Which kinesiotaping technique is effective? Comparision of two different techniques in patients with carpal tunnel syndrome

Background & Objective: Although different kinesiotaping (KT) techniques can be applied in the treatment of carpal tunnel syndrome (CTS), to our knowledge, there is no study in the literature showing the superiority of these techniques over each other. The aim of this study is to compare the effectiveness of KT techniques applied to the dorsal surface and palmar surface of the forearm in patients with CTS. Methods: Forty six patients (70 wrists) diagnosed with CTS were randomized into 3 groups. Fabricated night splint was applied to the first group, KT was applied to the palmar surface of the wrist to the second group, and KT was applied to the dorsal surface of the wrist to the third group. Clinical, electrophysiological and ultrasonographic evaluations before treatment and at the end of 3-week treatment were compared. Results: In the comparison pre- and post-treatment, the changes in pain evaluated with Visual Analog Scale, and median motor nerve distal latency were significant in all groups, the change in median nerve sensory conduction velocity was significant in Groups 1 and 2, the change in median motor nerve conduction velocity was significant in only Group 2, the change in The Boston Carpal Tunnel Questionnaire (BCTQ)-Symptom Severity Status was significant in Group 1 and Group 3, the change in BCTQ-Functional Severity Scale and median nerve cross-sectional area was significant in only group 1. When the changes in treatment between the groups were compared, no statistically significant difference was found in any of the parameters. Conclusion: While splinting and different KT methods provided various benefits in CTS patients, they were not statistically superior to each other.

Evaluation of Hand-Arm Vibration Syndrome Owing to Nerve Conduction Study and Cumulative Exposure Index-A 2.5-Year Cohort Study.

This study aims to clarify the relationship between peripheral neuropathy in hand-arm vibration syndrome and cumulative exposure index. 68 participants without symptoms were surveyed. The participants were divided into three groups based on past and current vibration exposure (VE). Comparison among groups according to past VE showed that the median and ulnar sensory nerve conduction velocities and median sensory nerve action potential (SNAP) amplitude were significantly lower in past high and low exposure groups than in the past nonexposure group. Comparison among groups according to current VE showed that the median and ulnar SNAP amplitudes were significantly lower in the current high exposure group than in the current low or nonexposure group. Vibration tool handlers have potential peripheral nerve lesions at a certain stage without subjective symptoms of the finger.

Effectiveness of manual therapy to the Cervical Spine on clinical outcomes and electrodiagnostic tests in people with carpal tunnel syndrome: A randomized controlled trial

ObjectiveTo determine if cervical spine manual therapy (CMT) plus conventional physical therapy (PT) optimizes clinical objective and self-reported outcomes, compared to PT alone, in people with carpal tunnel syndrome (CTS). MethodForty-eight patients with the diagnosis of CTS were randomly divided into conventional PT (control group) and conventional PT plus cervical spine manual therapy (intervention group). All patients received 10 sessions of supervised conventional physical therapy (wrist splint, electrotherapy and wrist joint mobilization). Patients in the cervical spine manual therapy group also had manual therapies techniques given to their neck. Visual analog scale (VAS), Boston Carpal Tunnel Questionnaire (BCTQ), the disabilities of the arm, shoulder, and hand (DASH) questionnaire, median nerve motor distal latency (mMDL), and median sensory nerve conduction velocity (mSNCV) were assessed at three points: baseline, post-intervention, and six months later. ResultsThe cervical spine manual therapy group showed significantly greater improvement in VAS, DASH score, mMDL, and mSNCV in post-intervention and follow-up compared to the conventional group. There was no significant difference in two subscales of BCTQ at post-intervention for two groups, whereas these two subscales showed a significant difference in favor of the cervical manual therapy group at follow-up. ConclusionThe analysis of results showed that conventional CMT combined with PT could be more effective in improving the clinical outcomes and electrodiagnostic findings of patients with CTS compared to conventional PT only in the long term. Therefore, it can be suggested as a proper therapeutic method in CTS.

Perineural 5% dextrose versus corticosteroid injection in non-surgical carpal tunnel syndrom treatment.

<p>We aimed to investigate the difference of clinical and electrophysiological improvement between perineural corticosteroid injection therapy (PCIT) and perineural 5% dextrose injection therapy (5%PDIT) in carpal tunnel syndrome (CTS).</p>. <p>Total of 92 wrists that were diagnosed as mild-to-moderate idiopathic CTS and completed their follow-up were included in our study. The severity of pain, symptom severity and functional status were asses&shy;sed by visual analog scale (VAS) and the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores for treatment effectiveness. Randomized wrists were administered PCIT or 5%PDIT accompanied by ultrasound guidance. VAS, BCTQ scores and the electro&shy;physiological study repeated before and after treatment at the 1st and 6th months after perineural injection therapies (PITs) were recorded.</p>. <p>Compared with baseline data, within groups there was significant improvement in VAS, BCTQ severity and function scores at 1st and 6th months follow-up (all p &lt; 0.001). Considerable advance were detected in the median sensory nerve conduction velocity (SNCV) when pretreatment values were compared with posttreatment first month in both groups (p = 0.01; p &lt; 0.001, respectively). No significant change occurred in median distal motor latency (DML) values between the 1st and 6th months in the groups (p = 0.095; p = 0.113, respectively). No significant difference was observed bet&shy;ween 5%PDIT and PCIT groups.</p>. <p>Clinical and electrophysiologic improvement in CTS began from 1st month after PCIT and 5%PDIT. At the 6th month follow-up of the patients, 5%PDIT and PCIT had similar therapeutic effects. As a result, we can consider the replacement of PCIT with 5%PDIT in mild-to-moderate CTS patients especially in those who are hesitant because of the corticosteroid&rsquo;s adverse effects.</p>.

A Pilot Study In to the Effects of Cervical Manual Therapy Plus Conventional Physical Therapy on Clinical Outcomes and Electrodiagnostic Findings in People With Carpal Tunnel Syndrome.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy that has a significant impact on patients' quality of life. Current physical therapy treatment options show limited effects or low-quality evidence, especially in the long term. To date, there has been little research to look at the effects of treating the cervical spine on decreasing symptoms distally to the carpal tunnel. This study aimed to evaluate the effects of cervical manual therapy plus conventional physical therapy on patients with carpal tunnel syndrome. This pilot pretest/posttest and six-month follow-up clinical study included 15 adult patients with CTS. For two weeks, each patient received 10 sessions of supervised intervention treatment. The efficacy of the therapies was assessed at baseline (T0), immediately after treatment (T1), and six months after treatment (T2). The visual analog scale (VAS), a symptom severity scale, the functional capacity scale of the Boston Carpal Tunnel Questionnaire (BCTQ), the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, median nerve motor distal latency (mMDL), and median sensory nerve conduction velocity (mSNCV) were outcome measures. There were significant improvements in all measures between the baseline values at T0 and those recorded immediately after the treatment at T1 or six months later at T2 (p<.05). This pilot study indicates that cervical manual therapy plus conventional physical therapy applied for two weeks improves clinical outcomes and electrodiagnostic findings in people with CTS.

Use of Iontophoresis with Corticosteroid in Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis.

Carpal tunnel syndrome is a neuropathy that affects the median nerve. The aim of this review is to synthesize the evidence and perform a meta-analysis on the effects of iontophoresis in people with carpal tunnel syndrome. The search was carried out using PubMed, Web of Science, Scopus, CINHAL Complete, Physiotherapy Evidence Database, and SciELO. The methodological quality was evaluated using PEDro. A standardized or mean difference meta-analysis (Hedge's g) using a random-effects model was calculated. Seven randomized clinical trials using iontophoresis for electrophysiological, pain, and functional outcomes were included. The mean of PEDro was 7/10. No statistical differences were obtained for the median sensory nerve conduction velocity (SMD = -0.89; p = 0.27) or latency (SMD = -0.04; p = 0.81), motor nerve conduction velocity (SMD = -0.04; p = 0.88) or latency (SMD = -0.01; p = 0.78), pain intensity (MD = 0.34; p = 0.59), handgrip strength (MD = -0.97; p = 0.09), or pinch strength (SMD = -2.05; p = 0.06). Iontophoresis only seemed to be superior in sensory amplitude (SMD = 0.53; p = 0.01). Iontophoresis did not obtain an enhanced improvement compared to other interventions, but no clear recommendations could be made due to the limited number of included studies and the heterogeneity found in the assessment and intervention protocols. Further research is needed to draw sound conclusions.

Effect of Wrist Dorsiflexion/Palmar Flexion on Median Nerve Deviation and Cross-Sectional Area in Patients with Carpal Tunnel Syndrome.

To evaluate the effect of wrist dorsiflexion/palmar flexion on median nerve excursion and cross-sectional area in patients with carpal tunnel syndrome. From November 2019 to December 2021, 85 patients (110 affected wrists) who presented to our department and were diagnosed with carpal tunnel syndrome were collected and classified by severity as mild to moderate. Twenty-five healthy controls were selected during the same period, with a total of 50 healthy wrists. All patients and healthy volunteers underwent high-frequency ultrasonography to measure the vertical deviation between the median nerve and the transverse carpal ligament during wrist dorsiflexion/palmar flexion and the changes in the cross-sectional area of the median nerve in the pisiform plane. All patients with carpal tunnel syndrome underwent neurophysiological testing to measure median nerve sensory conduction velocity, sensory latency time, and sensorimotor point fluctuation amplitude. The mean age of the patients was 50 ± 8 years, the proportion of males was 18%, and the disease course was 2.3 ± 1.2 years. In terms of severity grading, 38 patients (34.5%) had mild carpal tunnel syndrome, 30 patients (27.3%) had moderate carpal tunnel syndrome, and 42 patients (38.2%) had severe carpal tunnel syndrome. Compared with the control group, the distance between the proximal median nerve and the transverse carpal ligament, the distance between the distal median nerve and the transverse carpal ligament, and the cross-sectional area were decreased in the carpal tunnel syndrome group compared with those during wrist dorsiflexion, and the differences were statistically significant (P < 0.05). Compared with the control group, there were significant differences in the vertical distance and cross-sectional area between the median nerve and the transverse carpal ligament at the proximal and distal ends in the mild, moderate, and severe groups (P < 0.05). The proximal vertical distance of the median nerve was positively correlated with sensory latency (P < 0.05) and negatively correlated with sensory conduction velocity (P < 0.05). The vertical distance of the distal end of the median nerve was also significantly positively correlated with sensory latency (P < 0.05) and significantly negatively correlated with sensory conduction velocity (P < 0.05). Wrist dorsiflexion/palmar flexion can affect median nerve deviation and cross-sectional area in patients with carpal tunnel syndrome. High-frequency ultrasound is helpful to detect such an effect and can also help determine the severity of carpal tunnel syndrome, which is worthy of clinical promotion.

Five Traditional Chinese Medicine External Treatment Methods Combined with Mecobalamin for Diabetic Peripheral Neuropathy: A Network Meta-Analysis.

Diabetic peripheral neuropathy (DPN) is one of the most common chronic complications of diabetes. Traditional Chinese medicine (TCM) external treatment has been widely used in China as adjunctive treatment, and some small sample clinical studies have proved its effectiveness. However, due to the limited number of studies, we used network meta-analysis to compare the effectiveness of 5 commonly used external treatment methods of traditional Chinese medicine in the treatment of diabetic peripheral neuropathy. We searched PubMed, EMBASE, The Cochrane Library, Web of Science, CNKI, CBM, WanFang Knowledge Service Platform, and VIP databases and collected and screened randomised controlled trials on the external treatment of traditional Chinese medicine combined with mecobalamin in the treatment of DPN according to the inclusion and exclusion criteria. The search period was from 2011 to May 2021. The quality of included studies was assessed using the revised Cochrane risk-of-bias tool for randomized trials. The outcome indicators are Toronto score, median nerve sensory conduction velocity, and median nerve motor conduction velocity. A total of 22 publications were included in the study. The results of the network meta-analysis showed that acupuncture combined with mecobalamin was superior to other TCM external treatments combined with mecobalamin in terms of decreasing the Toronto score (MD = -2.8, 95% CI: -5.2∼-0.49), improving median nerve sensory conduction velocity (MD = 3.6, 95% CI: 2.4∼4.9), and median nerve motor conduction velocity (MD = 4.5, 95% CI: 2.6∼6.5). The SUCRA value and probability ranking chart showed that among the three outcome indicators, acupuncture combined with mecobalamin was the best, followed by acupoint injection combined with mecobalamin. In this network meta-analysis, acupuncture combined with mecobalamin shows the best results in the treatment of DPN, followed by acupoint injection combined with mecobalamin.

Influence of ergonomic factors on peripheral neuropathy under HAV exposure.

Hand-arm vibration (HAV) is a risk factor for carpal tunnel syndrome (CTS) and ulnar neuropathy at the elbow (UNE). It is unclear how ergonomic factors influence the relationship between HAV exposure and CTS and UNE. We aimed to assess the relationship between cumulative HAV exposure and CTS and UNE in workers exposed to HAV from two tools with different ergonomic profiles. We performed nerve conduction studies (NCSs) of the sensory and motor median and ulnar nerves and recorded symptoms indicating CTS and UNE in workers exposed to HAV from impact wrenches or from rock drills. Exposure was measured as cumulative lifetime exposure. We used linear regression adjusted for age and body mass index to assess linear relationships. Sixty-five workers participated (33 rock drill and 32 impact wrench operators). We found inverse linear associations between cumulative HAV exposure and median nerve sensory conduction velocity in impact wrench operators and ulnar nerve motor conduction velocity in rock drill operators (beta of 0.63 and 0.75). Based on NCS findings and symptoms, seven impact wrench operators had CTS and one UNE, and four rock drill operators had CTS and six UNE. Our findings indicate that ergonomic factors influence the development of CTS and UNE under HAV exposure. The ergonomic profile seems to influence which type of neuropathy workers exposed to HAV will develop. Design of occupational exposure guidelines and future studies should be based on ergonomic profile and exposure characteristics for different tools and not merely HAV.

Systematic review and Meta-analysis of efficacy and safety of Shuxuetong Injection in treatment of diabetic peripheral neuropathy

The present study evaluated the efficacy and safety of Shuxuetong Injection in the treatment of diabetic peripheral neuropathy(DPN). PubMed, Cochrane Library, EMbase, CNKI, VIP, SinoMed, and Wanfang were searched for randomized controlled trials(RCTs) of Shuxuetong Injection in the treatment of DPN from database inception to July 18, 2021. Literature screening was carried out according to the inclusion and exclusion criteria, and the required information was extracted. Cochrane risk-of-bias tool was used to evaluate the quality of the included trials, and RevMan 5.3 was used for Meta-analysis. Finally, six articles were included, involving 507 patients. The overall quality of included RCTs was not high. As revealed by Meta-analysis results, in terms of DPN score, one trial showed a significant difference in the experimental group before and after treatment, and the symptom of the experimental group was significantly improved compared with that in the control group after treatment. After treatment, a significant difference in DPN scores of the experimental group and the control group was observed(P&lt;0.05), and the symptom improvement of the experimental group was significantly better than that of the control group. In terms of sensory nerve conduction velocity(SCV), the experimental group was superior to the control group in improving conduction velocities(MD_(median SCV)=4.45, 95%CI[2.79, 6.10], P&lt;0.000 01; MD_(peroneal SCV)=6.70, 95%CI[5.64, 7.75], P&lt;0.000 01; MD_(posterior tibial SCV)=4.03, 95%CI[0.56, 7.49], P=0.02). In terms of motor nerve conduction velocity(MCV), compared with the conditions before treatment, the conduction velocities of median nerve, peroneal nerve, and posterior tibial nerve in both groups increased after treatment(P&lt;0.01). The experimental group was superior to the control group in improving MCV after treatment(P&lt;0.05). In terms of average blood glucose change, there is no statistical significance of the improvement of average blood glucose between experimental group and the control group(MD=-0.15, 95%CI[-0.82, 0.51], P=0.65). In terms of overall response rate, the curative effect of the experimental group in the treatment of DPN was superior to that of the control group(RR=1.23, 95%CI[1.11, 1.37], P=0.000 1). In terms of adverse events, no obvious adverse events were reported in the included RCTs. In light of existing data and indexes, the clinical efficacy of Shuxuetong Injection combined with western medicine in the treatment of DPN may be superior to that of conventional western medicine. It can improve the clinical symptoms, SCV, MCV, and average blood glucose of DPN, with good safety. However, existing clinical trials are few and the quality is low. It is recommended to further verify the above conclusions with internationally recognized outcome indicators.

The Relationship between Nerve Conduction Study and Clinical Grading of Carpal Tunnel Syndrome in Bangladeshi Population

Introduction: The CTS is one of the clinical syndromes, it was experienced by the patients from numbness, tingling, burning and or pain associated with localized compression of the median nerve at the wrist. Median nerve with the carpel tunnel (CTS) is localized and it was compressed in median nerve, resulting in mechanical compression and local ischemia has been associated with age and sex matched control. Objective: To assess The Relationship between Nerve Conduction Study and Clinical Grading of Carpal Tunnel Syndrome in Bangladesh Population. Methods: A prospective study was conducted at Department of Neurology, Uttara Adhunik Medical College Hospital (UAMCH), Uttara, and Dhaka, Bangladesh from January to December 2021. A total 100 case were prospectively observed for the period of six months 50 patients’ with symptoms consistent with CTS and 50 age and sex matched healthy control subjects were examined. Based on clinical assessment, the study patients were divided into 03 groups with mild CTS, moderate CTS and severe CTS respectively as per Mackinnsons classification. The relationship between the clinical severity grade and various nerve conduction study parameters were correlated. The study was correlated with age and gender matched control intervention and we extrapolate the any significant correlation between the clinical grades and various attributes of study traits. All the traits were carefully assessed by using logistic regression analysis and Fisher F- test statistics. Results: Out of 50 patients with symptoms consistent with CTS and 50 age and sex matched healthy control subjects were examined. The Left hand was involved in 11patients; right hand in 19 patients &amp; 20 patients had involvement of both hands. Numbness and tingling of hand and first three fingers was the most common presenting symptom. Phalens test was positive 30 (60.0%) of our patients. 7(14.0%) pts had hypothyroidism, 10(20%) patients showed raised DM and 4(8.0%) patients showed lipid profile abnormalities. Both male and female sex ratio was 1:3. All cases were considered for the study. The distal motor latency was significantly correlated with different age group of the population and CMAP and conduction velocity not shows any significant relation with clinical severity of CTS. Since, the median sensory latency and nerve conduction velocity seen in study population and well apprehension with clinical different grading of CTS. Conclusion: Summing of the results concludes that, the sensory conduction appears to be more sensitive (95%) AUC 0.89 and significantly correlated when compared to motor conduction attributes, the correlation besides with clinical severity of CTS apart from gender and age matched cases.

Local Corticosteroid Injections versus Surgical Carpal Tunnel Release for Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis.

Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. This meta-analysis compared local steroid injections (LSIs) versus carpal tunnel release (CTR) for the management of CTS. Neurophysiological parameters, patient-reported outcome measures (PROMs), and the complication rate were investigated. We hypothesized that LSIs may represent an effective and safe alternative to surgical management. Methods: This systematic review was conducted according to the 2020 PRISMA statement. All the clinical investigations comparing LSIs versus CTR for carpal tunnel syndrome were accessed. In March 2022, the following databases were accessed: Pubmed, Web of Science, Google Scholar, and Embase. No time constrains were used for the search. The risk of bias and statistical analyses were conducted using the Review Manager Software 5.3 (The Nordic Cochrane Collaboration, Copenhagen). Results: Data from 1096 procedures were retrieved. The mean follow-up was 12.3 (1 to 58) months. The mean age of the patients was 51.1 ± 4.6. Nocturnal paraesthesia (p < 0.0001) and visual analogue scale (p < 0.0001) were greater in the LSIs cohort. No difference was found in the functional (p = 0.2) and symptom (p = 0.4) subscales of the Boston Carpal Tunnel Questionnaire (BCTQ), median nerve distal motor latency (p = 0.9), median nerve motor amplitude (p = 0.7), median nerve sensory conduction velocity (p = 0.4), or median nerve sensory amplitude (p = 0.3). No difference was found in terms of minor complications (p = 0.9). No major complications were observed within the duration of follow-up. Conclusion: Both CTR and LSIs were effective and feasible in reducing symptoms of carpal tunnel syndrome. Though LSIs led to greater pain relief, this superiority was not permanent. Irrespective of the severity of the symptoms, current evidence suggests that a cycle of LSIs may be considered in patients with CTS. However, patients must be aware that LSIs may not be the definitive therapy, and CTR should be recommended.

Heart rate-corrected QT interval: A novel diagnostic biomarker for diabetic peripheral neuropathy.

Aims/IntroductionTo explore the relationship between heart rate‐corrected QT (QTc) interval and diabetic peripheral neuropathy (DPN), and whether QTc interval has diagnostic utility for DPN beyond nerve conduction velocity.Materials and MethodsA total of 965 patients with diabetes, including 473 patients with DPN and 492 patients without DPN, underwent standard 12‐lead electrocardiography and detailed assessments of peripheral neuropathy.ResultsPatients with DPN had longer QTc intervals than those without. Among participants, from the first to fourth quartile of QTc interval, the proportion of patients with DPN appreciably increased and the nerve conduction velocity obviously decreased (P for trend <0.001). The univariate and multivariate analyses showed that prolonged QTc interval was closely associated with increased risk of DPN (univariable odds ratio 1.112, 95% confidence interval 1.097–1.127, P < 0.001; multivariable odds ratio 1.118, 95% confidence interval 1.099–1.137, P < 0.001). Receiver operating characteristic analysis for the diagnosis of DPN showed a greater area under the curve for QTc interval of 0.894 than the median nerve motor conduction velocity of 0.691, median nerve sensory conduction velocity of 0.664 and peroneal nerve motor conduction velocity of 0.692. The optimal cut‐off point of QTc interval for DPN was 428.5 ms with sensitivity of 0.715 and specificity of 0.920 (P < 0.001). The combination of QTc interval and nerve conduction testing increased the area under the curve for the diagnosis of DPN (from 0.736 to 0.916; P < 0.001).ConclusionsQTc interval with 428.5 ms has more reliable diagnostic utility for DPN than nerve conduction velocity, and prolonged QTc interval is closely associated with an increased risk of DPN.

Ultrasonographic and electrophysiological outcomes of carpal tunnel syndrome treated with low-level laser therapy: A double-blind, prospective, randomized, sham-controlled study.

Objectives The aim of this study was to investigate the therapeutic effects of low-level laser therapy (LLLT) on clinical, ultrasonographic (US), and electrophysiological findings in carpal tunnel syndrome (CTS).Patients and methods Between January 2015 and August 2015, 42 patients (7 males, 35 females; mean age: 50.4±8.7 years; range, 32 to 65 years) with mild-to-moderate CTS were randomly assigned to one of two groups: active LLLT (therapy group, n=22) 0.8 J/painful point and sham LLLT groups (n=20). Both groups wore neutral wrist orthoses. The patients were evaluated before and after 15 sessions of therapy (670 nm, 4 J/session over the carpal tunnel). Follow-up parameters included the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) Symptom Severity Scale (SSS), Functional Status Scale (FSS), nerve conduction studies and US evaluation of the median nerve cross-sectional area (CSA), vascularization (via power Doppler), flattening ratio (FR), and palmar bowing of the flexor retinaculum.Results Nocturnal paresthesia improved in both groups; however, pain and patients with a positive Phalen’s test reduced only in the therapy group (p=0.031). The FSS and SSS scores also improved only in the therapy group (p<0.001). Electrophysiologically, median sensory nerve conduction velocities showed a significant improvement only in the therapy group (p=0.002). The CSA, FR, and vascularization of the median nerve showed a significant improvement in the therapy group alone (p<0.001, p=0.048, and p=0.021, respectively).Conclusion Improvements in the signs and symptoms of CTS and hand function, the improvements in sensory nerve conduction studies, and reduction in median nerve CSA, FR and vascularity in the LLLT group can be attributed to the anti-inflammatory and analgesic effects of LLLT. This study provides new US data demonstrating efficacy of LLLT along with a clinical and electrophysiological improvement. The LLLT seems to be an easily applied, non-invasive treatment option.

Ultrasound-Guided Triamcinolone Acetonide Hydrodissection for Carpal Tunnel Syndrome: A Randomized Controlled Trial.

Background: Despite the wide use of corticosteroid hydrodissection for carpal tunnel syndrome (CTS), there is insufficient evidence to confirm its efficacy. This study aimed to compare the effectiveness of corticosteroid hydrodissection vs. corticosteroid perineural injection alone on clinical and electrophysiological parameters in patients with CTS.Method: This prospective randomized controlled trial (RCT) was conducted in a tertiary care center with a follow-up period of 12 weeks. Subjects were randomly assigned to either ultrasound-guided hydrodissection with a mixture of 1 mL of triamcinolone acetonide (10 mg/mL), 1 mL of 2% lidocaine, and 8 mL normal saline or ultrasound-guided perineural injection with 1 mL of triamcinolone acetonide (40 mg/mL) and 1 mL of 2% lidocaine. The primary outcome measure was the symptom severity subscale (SSS) of Boston Carpal Tunnel Questionnaire (BCTQ) scores at baseline and at 6 and 12 weeks' post-treatment. The secondary outcomes included the functional status subscale (FSS) of BCTQ and the distal motor latency and sensory nerve conduction velocity of the median nerve. The effect of interventions on the designated outcome was analyzed using a 3 × 2 repeated measures analysis of variance. The within-subject and among-subject factors were differences in time (before the intervention, and 6 and 12 weeks after injection) and intervention types (with or without hydrodissection), respectively.Results: Sixty-four patients diagnosed with CTS were enrolled. Both groups experienced improvement in the SSS and FSS of BCTQ and median nerve distal motor latency and sensory nerve conduction velocity. However, group-by-time interactions were not significant in any outcome measurements. No serious adverse events were reported in either group, except for two patients in the hydrodissection group who reported minor post-injection pain on the first day after the intervention, which resolved spontaneously without the need for additional treatments.Conclusion: Hydrodissection did not provide an additional benefit compared to corticosteroid perineural injection alone. More prospective studies are needed to investigate the long-term effectiveness of corticosteroid hydrodissection, as well as its influence on median nerve mobility.

Withdrawal: “Efficacy of cervical manual therapy plus conventional physical therapy on clinical outcomes in patients with carpal tunnel syndrome: A double blind randomized controlled trial” Milad Zarrin, Maryam Saadat, Mohammad Jafar Shaterzadeh Yazdi, Davood Shalil Ahmadi

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Current physical therapy treatment options show limited effects or low-quality evidence, especially in the long-term. To date, there has been little research to look at the effects of treating the cervical spine for decreasing symptoms distally to the carpal tunnel. So the aim of this study was to compare the effects of cervical manual therapy plus conventional physical therapy with conventional physiotherapy only in Carpal Tunnel Syndrome Subjects. A group of 46 patients with CTS was randomly allocated into two groups: Cervical manual therapy plus conventional physiotherapy (n = 23), and conventional physiotherapy (n = 22). All patients received 10 sessions of supervised intervention treatment for 2 weeks. The efficacy of the therapies was assessed before initiation of therapy and after completion of therapy using a visual analog scale (VAS), a symptom severity scale, the functional capacity scale of the Boston Carpal Tunnel Questionnaire (BCTQ), functional status of DASH questionnaire, measurement of median nerve motor distal latency (mMDL) and median sensory nerve conduction velocity (mSNCV). Cervical manual therapy plus conventional physiotherapy group showed significantly greater improvement in VAS, DASH score, mMDL and mSNCV (p < 0.05) compared to the conventional group. There was no significant difference in BCTQ for two groups (p > 0.05). The analysis of the results showed that conventional physiotherapy combined with Cervical manual therapy could be more effective in improving the pain, functional abilities, median nerve motor distal latency and median sensory nerve conduction velocity of patients with CTS compared with conventional physiotherapy only.

Frequency of Local Treatment in Carpal Tunnel Syndrome during Pregnancy

Background and Aim: The most common entrapment neuropathy is carpal tunnel syndrome (CTS). Carpal tunnel syndrome is caused by median nerve compression at the wrist joint. Idiopathic carpal tunnel syndrome is the most common cause. Among the other physiologic causes of carpal tunnel syndrome (wrist trauma, diabetes, hypothyroidism, rheumatoid arthritis, occupation, contraception, and pregnancy), pregnancy is the most common. The objective of the present study was to determine the frequency of local treatment in carpal tunnel syndrome during pregnancy. Materials and Methods: This cross-sectional study was carried out on 45 pregnant women with carpal tunnel syndrome in the departments of Neurology and Gynaecology, Ayub Teaching Hospital, Abbottabad from May 2020 to April 2021. Individuals who met the inclusioncriteria were enrolled in this study. Ethical approval and consent forms were taken from the participants. All the patients were treated with local treatment (dexamethasone acetate 4 mg and lidocaine 0.5 ml) under the carpal tunnel syndrome. Before and after 3 weeks of local injection, median nerve electro physiologic parameters through sensory nerve conduction velocity (SNCV), sensory latency (DSL), pain intensity (visual analog scale or VAS) and distal motor latency (DML) were all noted. Results: The mean age of the patients was 29± 5.3 years while mean weight gain was 13.2 ± 4.9 kg. The third trimester was the mostfrequent pregnancy trimester with carpal tunnel syndrome. Before and after 3weeks, the average pain score of injected dexamethasone acetate was 8.65 ±0.89 and 4.29 ± 0.74 respectively (p-value &lt; 0.005). Additionally, the median nerve SNCV transcarpalwas 32.9 ±7.1 and 25.1 ± 7.2 m/s (p-value = 0.001); while DSL median nerve was4.87±0.81 ms and 4.1±0.62. Lastly, the DML of the median nerve before and after 3weeks of local treatment was 5.2±1.03 and 4.69±0.54 ms respectively. Conclusion: Pain intensity and electrophysiological factors were considerablyimproved after local treatment dexamethasone acetate injection. Encouraging results have been offered for carpal tunnel syndrome with minimum invasive treatment in pregnant women. Keywords: Carpal tunnel syndrome, Pain intensity, local treatment

Clinical study on acupuncture combined with western medication for diabetic peripheral neuropathy: 针刺结合西药治疗糖尿病性周围神经病变临床研究

ObjectiveTo compare the clinical effect differences between western medication, acupuncture, and acupuncture combine with western medication in the treatment of diabetic peripheral neuropathy. MethodsNinety-three patients were randomized into western medication group, acupuncture group, and combination group, with 31 cases in each. The patients in western medication group were treated with lipoic acid injection and mecobalamin injection/ tablets. The patients in acupuncture group were treated with acupuncture, and the acupoints were selected according to the symptoms. The needles were retained for 30 min, once a day. The patients in combination group were treated with both western medication and acupuncture, specific methods as the above. The treatments were for 18 days in succession in all of three group. The motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of median nerve and common peroneal nerve, as well as the changes of symptoms and signs of patients were observed before and after treatment. The clinical effect was evaluated. ResultsAfter treatment, the median nerve MNCV in the three groups, the median nerve SNCV and common peroneal nerve MNCV in acupuncture group and combination groups, and the common peroneal nerve SNCV in acupuncture group were all higher than those of before treatment, with significantly statistical differences (all P<0.05). After treatment, the MNCV and SNCV of median nerve and common peroneal nerve in combination group were higher than those in western medication group and acupuncture group, with significantly statistical differences (all P<0.05). After treatment, the number of patients in the three groups with the symptoms and signs was lower than that of before treatment. The effective rate in combination group was 96.8% (30/31), higher than those of western medication group, 74.2% (23/31), and acupuncture group, 83.8% (26/31), with significantly statistical differences (both P<0.05). ConclusionAcupuncture combined with western medication in the treatment of diabetic peripheral neuropathy can improve the nerve conduction velocity and improve the symptoms and signs of diabetic patients, with a better effect than those of western medication and simple acupuncture.

A cross-sectional study on nerve conduction velocity in stable chronic obstructive pulmonary disease

Objectives: This study was undertaken with the aim to find out possible presence of subclinical peripheral neuropathy in patients of chronic obstructive pulmonary disease (COPD) and its association with advancing severity of disease. Changes in nerve conduction parameter values in these patients have been presented. Materials and Methods: Median, ulnar, peroneal motor, and sural sensory nerve conduction latency, amplitude, and velocity were recorded in 100 known cases of COPD in the age group of 25–65 years as per the standard protocol. Results: On analysis, statistically significant lowering of sural nerve conduction velocity (P = 0.002) and amplitude (P = 0.003) was found with decreasing FEV1% in the three stages of COPD. Decrease in ulnar sensory conduction amplitude and velocity was also noted but it was not significant. Fall in sural nerve conduction velocity was found to be strongly and positively correlated (P = 0.029, r = 0.444) with decrease in FEV1%. Conclusion: These findings suggest that with increasing severity of disease, airflow limitation enhances polyneuropathy in COPD patients. It is predominantly axonal and mainly involving sensory nerve.

Moxibustion for the treatment of diabetic peripheral neuropathy: A systematic review and meta-analysis following PRISMA guidelines.

At present, the effect of western-medicine (WM) therapy to treat diabetic peripheral neuropathy (DPN) is limited. Moxibustion is a representative external treatment in traditional Chinese medicine that has been beneficial to DPN. We aim to systematically assess the efficacy and safety of moxibustion in treating DPN, following PRISMA guidelines. Eight electronic databases were searched to acquire information on eligible trials published from inception to June 1, 2019. We included randomized controlled trials (RCTs) applying moxibustion therapy with a minimum of 14-days treatment duration for DPN patients compared with placebo, no intervention, or conventional WM interventions. The primary outcomes in our study include the sensory-nerve conduction velocity (SNCV) and motor-nerve conduction velocity (MNCV). We used the Cochrane Collaboration Risk of Bias tool to assess the methodological quality of eligible RCTs. Statistical analyses were conducted using Review Manager 5.3. Risk ratios (RR) and mean differences (MD) were calculated with a 95% confidence interval (CI). The χ test was applied to assess the heterogeneity. In total, 11 RCTs were included that involved 927 DPN patients. Compared with the control group, there was an increase in median MNCV (MD = 6.26, 95% CI 2.64-9.89, Z = 3.39, P = .0007) and peroneal MNCV (MD = 6.45, 95% CI 5.30-7.61, P < .00001). There was also an increase in median SNCV (MD = 6.64, 95% CI 3.25-10.03, P = .0001) and peroneal SNCV (MD = 3. 57, 95% CI 2.06-5.09, Z = 4.63, P < .00001) in the treatment groups. The treatment groups receiving moxibustion therapy indicated a more significant improvement in total effectiveness rate (RR = 0.25, 95% CI 0.18-0.37, Z = 7.16, P < .00001). Toronto Clinical Scoring System indicated a significant decrease in the treatment groups (MD = -2.12, 95% CI -2.82 to 1.43, P < .00001). Only 1 study reported that treatment groups experienced no adverse reactions. The other 10 studies did not mention adverse events. Moxibustion therapy may be an effective and safe option for DPN patients but needs to be verified in further rigorous studies.
