Efficacy of mirror therapy in improving hand function post flexor tendon repair

The aim of this study was to determine the efficacy of mirror therapy (MT) in improving the total active range of motion (AROM) of the affected finger, hand grip strength, and hand function in patients with flexor tendon repair (FTR) in zone II. The study was an open-label, parallel-group, randomized controlled trial. Thirty patients with zone II FTR, aged 20-45 years, were recruited and randomized into two equal groups: the MT group and the sham MT group. The intervention began in the fourth week post-operation, consisting of thirty minutes of MT or sham MT, three sessions per week for four weeks, in addition to the traditional physical therapy (PT) program. The total AROM of the interphalangeal (IP) joints of the affected fingers, hand grip strength, and hand function were assessed. After four weeks of intervention, the percentage change in total AROM was 25.7% in the MT group and 19.93% in the sham MT group. Additionally, hand grip strength and Michigan Hand Outcomes Questionnaire (MHQ) scores showed greater improvement in the MT group compared to the sham MT group (p < 0.05). Adding MT to the traditional PT program may be more effective than the traditional PT program alone in improving the AROM of the interphalangeal (IP) joints of the operated fingers, grip strength, and MHQ scores.

The Russian Version of the Michigan Hand Outcomes Questionnaire: Cross-Cultural Adaptation and Validation

Background. The Michigan Hand Outcomes Questionnaire (MHQ) is one of the most commonly used specialized scales to assess function, pain, aesthetic component, and overall patient satisfaction with their hands and wrists. However, to date, the scale has not been validated into Russian.
 Aim of the study — validation and cross-cultural adaptation of the Russian-language version of the questionnaire for patients with hand diseases MHQ.
 Methods. Validation and cultural adaptation were carried out in several stages: forward translation, back translation, formation of a preliminary version, pilot testing (pretesting), formation of the final version, with the help of which 50 patients were interviewed, of which 29 men (58%) and 21 women ( 42%), whose average age was 52.72 (25–84) years. Next, the psychometric properties of the questionnaire were assessed: validity, ceiling and floor effects, internal consistency (Cronbach’s α), reproducibility, completion rate. Patients completed the MHQ questionnaire upon initial visit to an orthopedic traumatologist and again the next day. Reproducibility was assessed using the intra-class correlation coefficient (ICC). Validity was assessed by studying the relationship between the results of the questionnaire under study and the results of the DASH questionnaire validated in Russia.
 Results. As part of the study, a rating scale was obtained with good psychometric properties: validity — 0.726, p0.001; Cronbach’s α 0.9, 95% CI (0.65–0.97); reproducibility — 0.92 (0.87–0.96); occupancy rate — 100%; the ceiling effect is observed in 42 questions 1–20, 22–27, 35, 37, 38, 42, 46–57, the floor effect in 13 questions — 17, 20, 28–32, 39–41, 43–45.
 Conclusions. The results of the study of the validity and retest reliability of the Russian version of the MHQ scale indicate that it is a reliable and reliable tool for assessing the function, pain, aesthetic component and overall satisfaction of patients with respect to their hands and wrists, which can be widely used by domestic researchers in practical and scientific activities.

Reverse dorsolateral proximal phalangeal island flap: Long-term results

ObjectivesThis study aims to present long-term follow-up results of the reverse dorsolateral proximal phalangeal island flap designed for reconstruction of large fingertip and pulp defects. MethodsWe examined 18 patients who underwent reverse dorsolateral proximal phalangeal island flap surgery to address ≥2.5 cm fingertip and pulp defects. Mean follow-up was 84.4 months. Sensitivity assessments were conducted using the Semmes–Weinstein monofilament and 2-point discrimination tests. Additionally, we evaluated finger joint active range of motion, complications and cold intolerance. ResultsMild venous congestion was observed in 5 flaps. Significant differences were observed in 2-point discrimination and Semmes-Weinstein monofilament tests between the injured and contralateral sides, specifically in the flaps, the dorsal side of the middle phalanx, and the donor site. The flap's mean static 2-point discrimination was 8.3 mm. Restricted distal interphalangeal joint extension was observed in 2 cases. Total active motion with the flap was good or excellent in the injured fingers, but with a significant difference between injured and contralateral fingers. Additionally, 42% of the injured fingers exhibited hook nail deformity, and 2 patients reported cold intolerance. Despite these issues, most patients has high scores for the appearance and satisfaction aspects of the Michigan Hand Outcomes Questionnaire. ConclusionIn moderate or larger fingertip defects, the reverse dorsolateral proximal phalangeal island flap serves as an alternative for reconstructing both fingertip and pulp issues. However, this option involves sacrificing some sensation in the dorsum of the middle phalangeal finger and the donor area. Level of evidenceIV, therapeutic study.

Estimation of Hand Function Impairment in Breast Cancer Survivors with Lymphedema

Breast cancer (BC) is one of the most frequent cancers in women, and breast cancer-related lymphedema (BCRL) is a common side effect of BC treatment. When the lymphatic drainage system is damaged, lymphedema develops, which further exacerbates swelling and leads to pain, an increase in limb circumference, a reduction in joint range of motion, and a decrease in the use of the affected hand for functional tasks. Handgrip strength is essential for performing upper limb functional daily activities. Less is known about the long-term effects of lymphedema on hand function. The objective of the study was estimation of hand function impairment in BC survivors with lymphedema. This study was carried out by randomly selecting 100 out of 1,200 women with lymphedema, aged between 40 and 80 years, and who underwent sentinel lymph node biopsy along with radiotherapy, were included in this study. The handgrip strength was tested using an electronic handheld dynamometer. The functional wrist and hand scales were used to evaluate hand function. The Michigan Hand Outcome Questionnaire (MHQ) was used to evaluate the hand's overall function. A statistical analysis was done using SPSS statistical software (version 23.0). Handgrip strength of the affected hand by BCRL when compared with the unaffected hand was reduced. Functional hand and wrist scale have shown very poor results of the affected hand when compared with the unaffected hand. Majority of participants in the MHQ were unsatisfied with the overall functioning of the hand (p < 0.0001). This study concluded that there was significant hand function impairment in BC survivors with lymphedema. BCRL had a negative impact on daily activities of the individual and also affected the mental, emotional, and social aspects. BCRL also had an impact on overall self-reported physical function and quality of life.

Incision techniques for trigger thumb release: a comparison of outcomes of four types of skin incision.

Although trigger thumb release is commonly performed, there is no consensus on the optimal skin incision. This study aimed to compare outcomes of four incision techniques, including V-shaped, oblique, transverse and longitudinal incisions. Outcomes included the Michigan Hand Outcomes Questionnaire, satisfaction with the treatment and postoperative complications. The results of 875 patients who underwent trigger thumb release were assessed. All groups demonstrated improvement in self-reported hand function (range of 10-14 points), pain (25-27 points) and aesthetics (4-7 points) from baseline to 3 months postoperatively with no differences between incision techniques. Of the patients, 76% reported good or excellent satisfaction with the outcome of treatment. Satisfaction and complication rates of the different incision techniques were similar. These findings imply that there is no clear benefit of one type of incision over another for trigger thumb release, suggesting that surgeons may use the technique of their preference.Level of evidence: III.

Tree-Based Reinforcement Learning for Identifying Optimal Personalized Treatment Decisions for Hand Deformity in Rheumatoid Arthritis.

Silicone metacarpophalangeal joint arthroplasty (SMPA) can reconstruct metacarpophalangeal (MCP) joint deformities in the rheumatoid hand, but patient selection criteria for the procedure remains unclear. We used statistical learning to elucidate patient selection criteria that will enhance long-term patient-reported and functional outcomes in patients with severe hand rheumatoid arthritis (RA). This is a secondary analysis of a prospective study of 169 adults with severe hand RA (average combined ulnar deviation (UD) and extensor lag (EL) at the MCP joint ≥ 50 degrees, per finger) with one-year follow-up, conducted at three centers in the United States and England from January 1, 2004, to December 31, 2011. Primary outcomes were Michigan Hand Outcomes Questionnaire (MHQ) pain sub-score, changes in EL, UD, and Arthritis Impact Measurement Scale (AIMS2) score. A tree-based reinforcement learning (T-RL) model was used to estimate clinical decision rules for treatment. 132 patients (mean[SD], 61[9] years; 108[72%] female) were included in the SMPA (n=50) and non-SMPA (n=82) cohorts. To minimize EL and UD, patients should undergo SMPA. To minimize pain, patients older than 55 should undergo SMPA. To increase hand-related quality-of-life (QOL), patients with grip strength <12 kg should undergo SMPA. Estimations with imputed missing data were similar, aside from a lower grip strength (<8 kg) threshold for hand-related QOL. Unless there is significant comorbidity that precludes surgery, most patients older than 55 with severe hand RA will have improved QOL, pain, and function after SMPA. Patients with preserved grip strength may benefit from continued medical management.

Management of the capsule in trapeziometacarpal joint implant arthroplasty: resection versus repair.

We compared the effects of capsule resection versus capsule suturing in patients treated with a dual-mobility trapeziometacarpal joint prosthesis. We included 131 patients with capsular resection and 57 patients with repair. The mean scores for pain and the brief Michigan Hand Outcomes Questionnaire were similar between the groups preoperatively and at 6 weeks and 1 year postoperatively. Mean key pinch strength was also similar in both groups before surgery and at 1 year, but higher in the capsular resection than in the suture group at 6 weeks. The incidence of complications reported throughout the 1-year postoperative period was not significantly different between the groups. One implant in the capsular resection group was revised for reasons most likely unrelated to capsule management. We conclude that the capsule can be safely resected during trapeziometacarpal joint implant arthroplasty.Level of evidence: III.

Outcomes of Headless Screw Fixation for Coronal Hamate Fractures

AIM The aim of this study is to clarify the surgical technique and to evaluate postoperative outcomes of patients who underwent open reduction and internal fixation (ORIF) with headless screws for the coronal hamate fractures. MATERIAL AND METHOD A retrospective evaluation was performed on a total of 9 patients who underwent ORIF with headless screws for the coronal hamate fracture between 2018 and 2021. Demographic information, surgical details, and clinical follow-up data were systematically collected. Postoperative clinical assessments were carried out using the Michigan Hand Outcome Questionnaire (MHQ) and Disabilities of the Arm, Shoulder and Hand (DASH) scores. RESULTS The mean age at surgery was 37 years (range: 18-49), and the mean follow-up period was 34 months (range: 24-50). Among the 9 patients with coronal hamate fractures, 5 experienced fractures and/or dislocations involving the 4th and/or 5th metacarpal bones. The median overall MHQ and DASH scores were 76.2 (range: 52.5-97.9, IQR: 68.45-83.95) and 6.7 (range: 0-35, IQR: 1.65-10), respectively. The follow-up X-rays revealed favorable healing of the fractures. CONCLUSION Coronal hamate fracture fixation can be effectively managed through fixation with headless screws. It is essential to address both coronal hamate fractures and any accompanying metacarpal fractures/dislocations to ensure optimal hand function. Mid-term follow-ups have demonstrated satisfactory outcomes.

Bone grafting combined with a spiral flap technique for the reconstruction of fingertip amputations.

Various reconstructive options exist for distal finger and pulp defects, including grafting and local or distant flaps. In addition to reconstructing the normal anatomical structure, preserving the sensory function of the finger is crucial. This study presents the results of using bone grafting combined with a spiral flap (BGcSF) technique for reconstructing pulp defects accompanied by bone loss. Twenty-three patients with fingertip defects were treated using the BGcSF technique. Flap sensitivity was assessed us-ing the Semmes-Weinstein monofilament (SWM) and static two-point discrimination (2PD) tests at six months postoperatively. Cold intolerance of the affected fingers was evaluated using the Cold Intolerance Severity Score (CISS) questionnaire at one year postop-eratively. Patient satisfaction was assessed using the Michigan Hand Outcomes Questionnaire (MHQ). Range of motion (ROM) for the proximal and distal interphalangeal joints was measured with a goniometer at one year postoperatively. Distal flap necrosis, affecting 10-15% of the flap area, was observed in one patient. No other complications were noted. The mean static two-point discrimination value at six months postoperatively was 5.6 mm, and the mean SWM score was 3.56. The mean CISS score at one year postoperatively was 18.8. The mean active ROM angle for the proximal interphalangeal joint was 106.7 degrees, and for the distal interphalangeal joint, it was 65.4 degrees. The mean MHQ score at one year postoperatively was 18.5. The BGcSF technique provides soft tissue with a texture similar to that of the fingertips and supports effective sensory repair. It can be considered a viable option for fingertip reconstruction in cases where replantation is not feasible.

Primary Arthrodesis of Non-thumb Metacarpophalangeal Joints of the Hand: Clinical and Patient-Reported Outcomes.

Metacarpophalangeal (MCP) joint arthritis is common secondary to a variety of inflammatory, degenerative, and traumatic causes. Although MCP arthroplasty is more common for the second to fifth digits, primary arthrodesis can be used for high-demand patients with arthritis or unsalvageable fractures of the MCP joint. There has been limited recent studies on the outcomes of these patients. A retrospective review of 38 fingers in 27 patients with primary arthrodesis from 1990 to 2020 was conducted. The major outcomes were complications, reoperations, radiographic union, and time to union. Patient-reported outcomes including the Michigan Hand Outcomes Questionnaire and a questionnaire specific to the operative MCP joint were collected. Rate of radiographic union was 84% including revisions. The average time to union was 3.6 months. Rates of complications, reoperation, and amputation were 26%, 16%, and 7%, respectively. Arthrodesis as part of emergent trauma reconstruction was significantly more likely to result in reoperation (50% vs 7%) and complication (63% vs 17%) than chronic arthritis. Patient-reported outcomes were fair to good with improvement in pain (79%), function (66%), and appearance (40%). Sixty-six percent (66%) of patients were satisfied with their surgery, and 73% would repeat the surgery. Arthrodesis for unsalvageable MCP fractures was associated with higher rates of reoperation and complication than inflammatory or degenerative arthritis. Excluding emergent trauma, MCP fusion was reliable with a reoperation rate of 7% and a modest complication rate of 17%. Patients rated reasonable levels of satisfaction and willingness to repeat the procedure despite complications.

Dorsal capsule release and lateral band translocation for a stiff swan neck deformity without articular involvement.

The treatment for proximal interphalangeal joint (PIP) stiffness in extension requires extensor tenolysis, concomitant procedures to restore flexion, and intensive therapy. A stiff swan neck deformity without articular involvement is rare and the treatment is always challenging. Six patients with stiff swan neck deformities were operated between 2016 and 2023, and the outcome was analyzed retrospectively. A dorsal capsule release and radial lateral band translocation volar to the PIP joint axis were done. This translocation was maintained by a sling formed by the flexor digitorum superficialis and the free margins of the accessory collateral ligament. The range of movements in the PIP joint, visual analog scale (VAS), and functional outcomes were analyzed by the Michigan Hand Outcome Questionnaire (MHOQ) score. The mean follow-up was 49.5months (range 48-52months). The mean preoperative PIP joint extension was 8 (range 5-10) degrees of extension), and the mean preoperative PIP joint flexion was 0. All patients improved after the surgery and the mean flexion of the PIP joint at follow-up was 95 degrees; extension was 1 degree (range 0-5 degrees). The mean Michigan Hand Outcomes Questionnaire (MHOQ) score was 92 (range 90-95) and the VAS was 0. Dorsal capsule contracture release and lateral band translocation to the volar axis of the PIP joint seem to be the possibilities for correcting stiff swan neck deformity. IV, retrospective case study.

Investigation of the effects of a short opponens splint and structured hand exercise program in computer engineers with wrist pain: a randomized controlled trial

Objectives. This study aimed to examine the effects of a short opponens splint and hand exercise program on pain, hand functionality, daily activities, and work efficacy in computer engineers with wrist pain. Methods. Forty-five engineers were randomized into three groups: group 1 (n = 15) utilized both splints and exercises, group 2 (n = 15) engaged in exercises only and group 3 (n = 15) received no treatment, across 8 weeks, thrice weekly. Only exercises were applied to group 2 (n = 15). No treatment was applied for group 3 (n = 15). The progress of subjects was controlled periodically each week. Outcome measurements including the Jamar hand dynamometer, pinchmeter, nine-hole peg test (9-NHPT), visual analog scale, Boston carpal tunnel syndrome questionnaire and Michigan hand outcome questionnaire (MHQ) were evaluated pre and post treatment during the study period. Results. Comparing the outcome measurements of the three groups showed a statistically significant difference between them except for the 9-NHPT and MHQ pain and esthetics (p < 0.05). According to post-hoc tests, groups 1 and 2 had more significant differences than group 3. Also, there was no statistically significant difference in any parameter between group 1 and group 2 (p > 0.017). Conclusion. Non-restrictive minimal orthosis or exercise programs are advisable for individuals with wrist pain.

ACUTE CARPAL TUNNEL SYNDROME: RESULTS OF A PROTOCOL FOR EARLY NERVE DECOMPRESSION AND SURGICAL STABILIZATION FOR BONY WRIST TRAUMA

We undertook this study to investigate the outcomes of surgical treatment for acute carpal tunnel syndrome following our protocol for concurrent nerve decompression and skeletal stabilization for bony wrist trauma to be undertaken within 48-hours.We identified all patients treated at our trauma centre following this protocol between 1 January 2014 and 31 December 2019. All patients were clinically reviewed at least 12 months following surgery and assessed using the Brief Michigan Hand Outcomes Questionnaire (bMHQ), the Boston Carpal Tunnel Questionnaire (BCTQ) and sensory assessment with Semmes-Weinstein monofilament testing.The study group was made up of 35 patients. Thirty-three patients were treated within 36-hours. Patients treated with our unit protocol for early surgery comprising nerve decompression and bony stabilization within 36-hours, report excellent outcomes at medium term follow up.We propose that nerve decompression and bony surgical stabilization should be undertaken as soon as practically possible once the diagnosis is made. This is emergent treatment to protect and preserve nerve function. In our experience, the vast majority of patients were treated within 24-hours.

Results of Pyrocarbon Disc Interposition Compared to Trapeziectomy with Ligament Reconstruction and Tendon Interposition.

To compare pyrocarbon disc interposition arthroplasty (PDI) with trapeziectomy plus ligament reconstruction tendon interposition (LRTI), the authors assessed whether PDI resulted in a higher pinch strength, and compared grip strength, range of motion (ROM), patient-reported outcomes, satisfaction, and complications between the approaches. Because of scarcity of preoperative hand measurements, the authors performed a descriptional cross-sectional cohort study of patients operated on between 2006 and 2014, with a minimum of 5 years of follow-up. Patients were treated with PDI or LRTI. The authors determined key pinch strength as the primary outcome, followed by tip and tripod pinch, grip strength, palmar abduction and opposition, Michigan Hand Outcomes Questionnaire (MHQ) and Patient-Reported Hand and Wrist Evaluation (PRWHE) scores, satisfaction level, and complications. Propensity score matching was used to match the study groups on demographic variables. A ratio of 2:1 was used, resulting in inclusion of 62 (of 154) PDI and 31 (of 31) LRTI thumbs. Patients in the PDI group showed stronger key and tip pinch strength than did patients in the LRTI group ( P = 0.027 and P = 0.036, respectively). Tripod pinch, grip strength, and ROM were equal between the groups. MHQ and PRWHE were comparable, with higher satisfaction levels in the PDI group. Eight patients with PDI were converted to LRTI because of pain. This study confirmed the hypothesis that key and tip pinch strength is stronger after PDI compared with LRTI for first carpometacarpal joint osteoarthritis. Both techniques have comparable outcomes considering patient-reported outcome (MHQ and PRWHE), ROM, and complications. Therapeutic, III.

Single or double Kirschner wire fixation: which provides better outcomes for pediatric proximal phalanx base fractures?

The most common hand fracture in children is seen at the base of the proximal phalanx. This study aims to compare clinical outcomes of single versus double Kirschner wire pinning for pediatric proximal phalanx base fractures. The retrospective study enrolled patients who underwent closed K-wire pinning for proximal phalanx base fractures from January 2016 to February 2022. We divided patients into two groups based on the number of K-wire inserted (single versus double). Demographics, removal of implant, complication rate were analyzed. Patients were asked to answer the Michigan Hand Outcomes Questionnaire (MHQ) by telephone. Data including fracture type, diaphyseal axis-metacarpal head angle (DHA) and Total Active Flexion Scale (TAFS) were analyzed. This study included 37 pediatric patients with proximal phalanx base fractures, treated with either single (n = 10) or double K-wire (n = 27) fixation. The mean operation time was significantly shorter for the single K-wire group. No significant differences were observed in complication rates, TAFS, implant removal times, MHQ, or pre- and post-operative DHA between the two groups. The single K-wire technique demonstrates similar effectiveness to the double K-wire technique in treating pediatric proximal phalanx base fractures, with the added benefit of shorter operation time. Therefore, the choice between using one or two K-wires should be determined based on the surgeon's proficiency and preference.

FUNCTIONS, SLEEP, FATIGUE AND QUALITY OF LIFE IN PATIENTS WITH SCLERODERMA DURING COVID-19: CROSS - SECTIONAL STUDY

Purpose: COVID-19, which has affected people in various ways, has also shown to cause various limitations on the lives of Scleroderma patients. The current study aims at evaluating the upper extremity functions, sleep quality, fatigue, and health-related quality of life in Scleroderma patients and to determine the factors affecting upper extremity functions.&#x0D; Methods: A total of 83 participants were recruited in this study. Of the participants, 39 were Scleroderma patients (mean age 43.28±9.96 years) and 44 were healthy controls (mean age 40.05±8.89 years). The Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) and Michigan Hand Outcomes Questionnaire (MHQ) were applied to evaluate upper extremity functions of the participants. Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and the Scleroderma Health Assessment Questionnaire (SHAQ) were used to evaluate the sleep quality, fatigue, and health-related quality of life, respectively.&#x0D; Results: Scleroderma patients had significantly lower scores in hand functions, sleep quality, fatigue, and health-related quality than the healthy group (p=0.001). The correlations between DASH and PSQI (r=0.559, p=0.001), FSS (r=0.496, p=0.001), SHAQ scores (r=0.754, p=0.001) were highly positive. Similarly, a high correlation was found between MHQ and SHAQ scores (r=-0.679, p=0.001).&#x0D; Conclusion: Upper extremity functions and health-related quality of life were found to be affected in patients with Scleroderma. It was revealed that upper extremity functions were affected by sleep quality, fatigue, and health-related quality of life. Therefore, knowing all these effects and their relationships with each other allows to draw a systematic treatment plan on Scleroderma patients.

Effect of Adding Kinesiotaping to Median Nerve Gliding Exercise Toward Hand Performance of Patients with Carpal Tunnel Syndrome by Using Michigan Hand Outcomes Questionnaire

Background: CTS occurs due to local compression of the median nerve with manifestations of neuropathy, mostly in the productive population. Many conservative treatments have been observed to reduce the degree of pain and quality of life in CTS patients. Kinesiotaping is a new therapy that has been widely used for various musculoskeletal conditions and is known for reducing median nerve compression. Aim: To determine the effect of adding kinesiotaping to median nerve gliding exercise on hand function in CTS patients by using the Michigan Hand Outcomes Questionnaire. Methods: This research was an experimental randomized pre-and post-test group design. A sample of 24 patients from the Medical Rehabilitation Outpatient in RSUP Dr. Kariadi were divided into two groups randomly. The intervention group (n=12, dropout 1) got kinesiotaping application and median nerve gliding exercise. The control group (n=12, dropout 1) did the median nerve gliding exercise only. Hand performance has been evaluated before and at the end of the 4th week of treatment by using the Michigan Hand Outcomes Questionnaire. Result: There were significant improvements in the intervention group’s right-hand function (p&lt;0,001), activities of daily living (ADLs) or the ability of the right hand to do certain tasks (p&lt;0,001), work performance (p&lt;0,001), pain (p=0,024), and satisfaction (p&lt;0,001), as compared to the control group. Meanwhile, the intervention and the control group did not show significant differences in left-hand function score (p=0.884), left-hand ability score (p=0.884), and aesthetics score (p=1,000). Conclusion: There was a positive effect on improving hand performance in CTS patients by adding kinesiotaping to median nerve gliding exercises.

Explaining Personalized Activity Limitations in Patients With Hand and Wrist Disorders: Insights from Sociodemographic, Clinical, and Mindset Characteristics

ObjectivesTo investigate the association of sociodemographic, clinical, and mindset characteristics on outcomes measured with a patient-specific patient-reported outcome measure (PROM); the Patient Specific Functional Scale (PSFS). Secondly, we examined whether these factors differ when a fixed-item PROM, the Michigan Hand Outcome Questionnaire (MHQ), is used as an outcome. DesignCohort study, using the aforementioned groups of factors in a hierarchical linear regression. SettingTwenty-six clinics for hand and wrist conditions in the Netherlands. ParticipantsTwo samples of patients with various hand and wrist conditions and treatments: n=7111 (PSFS) and n=5872 (MHQ). InterventionsNA. Main Outcome MeasuresThe PSFS and MHQ at 3 months. ResultsThe PSFS exhibited greater between-subject variability in baseline, follow-up, and change scores than the MHQ. Better PSFS outcomes were associated with: no involvement in litigation (β[95% confidence interval=-0.40[-0.54;-0.25]), better treatment expectations (0.09[0.06;0.13]), light workload (0.08[0.03;0.14]), not smoking (-0.07[-0.13;-0.01]), men sex (0.07[0.02;0.12]), better quality of life (0.07[0.05;0.10]), moderate workload (0.06[0.00;0.13]), better hand satisfaction (0.05[0.02; 0.07]), less concern (-0.05[-0.08;-0.02]), less pain at rest (-0.04[-0.08;-0.00]), younger age (-0.04[-0.07;-0.01]), better comprehensibility (0.03[0.01;0.06]), better timeline perception (-0.03[-0.06;-0.01]), and better control (-0.02[-0.04;-0.00]). The MHQ model was highly similar but showed a higher R2 than the PSFS model (0.41 vs 0.15), largely due to the R2 of the baseline scores (0.23 for MHQ vs 0.01 for PSFS). ConclusionsHealth care professionals can improve personalized activity limitations by addressing treatment expectations and illness perceptions, which affect PSFS outcomes. Similar factors affect the MHQ, but the baseline MHQ score has a stronger association with the outcome score than the PSFS. While the PSFS is better for individual patient evaluation, we found that it is difficult to explain PSFS outcomes based on baseline characteristics compared with the MHQ. Using both patient-specific and fixed-item instruments helps health care professionals develop personalized treatment plans that meet individual needs and goals.

The effectiveness of mobilization with movement on patients with mild and moderate carpal tunnel syndrome: A single-blinded, randomized controlled study

Study designSingle-blinded, randomized controlled study. IntroductionCarpal Tunnel Syndrome (CTS) causes pain and loss of function in the affected hand. The mobilization with movement (MWM) technique is a manual therapy method applied to correct joint movement limitation and to relieve pain and functional disorders. Purpose of the studyThis study aimed to examine the effectiveness of MWM technique on pain, grip strength, range of motion, edema, hand reaction, nerve conduction, and functional status in patients with CTS. MethodsA total of 45 patients enrolled in the study. The MWM group (n = 18) completed a 4-week combined conservative physiotherapy and MWM program, whereas the control group (n = 18) received only the 4 weeks of conservative physiotherapy. Pain severity according to the numerical rating scale was used as primary outcome. ResultsWe found an improvement within the subjects in resting pain (MWMG:5.1 ± 3.6 vs 1.1 ± 2.4, Effect Size (ES)=1.3; CG:4.5 ± 3.3 vs 1.0 ± 2.2, ES=1.1), in activity pain (MWMG:6.5 ± 3.7 vs 1.1 ± 2.4, ES=1.5; CG:4.8 ± 3.4 vs 2.2 ± 2.3, ES=1) and in night pain (MWMG:5.9 ± 3.2 vs 1.8 ± 2.5, ES=1.2; CG:5.3 ± 4.2 vs ± 2.3 ± 3.5, ES=0.9). For between the groups, a statistical difference was found for the activity pain, Disabilities of the Arm Shoulder and Hand Questionnaire score (MWMG:52.2 ± 23.8 vs 27 ± 24.7, ES=1.3; CG:47.0 ± 24.8 vs 41.5 ± 22.1, ES=0.2), Michigan Hand Outcomes Questionnaire (MHQ-1), (MWMG:44.4 ± 23.7 vs 74.7 ± 24.5, ES=1.3; CG:44.8 ± 17.4 vs 57.4 ± 21.7, ES=0.9) and MHQ-5 (MWMG:68.8 ± 13.1 vs 82.5 ± 11.5, ES=0.9; CG:63.4 ± 26.7 vs 59.3 ± 25.8, ES=0.1) parameters in favour of MWM group. DiscussionThis study showed that MWM compared to conservative physiotherapy might be more effective in reducing perceived symptoms in mild and moderate CTS patients. ConclusionsMWM produced a small benefit to recovery of activity pain and upper extremity functionality level outcomes of patients with mild to moderate CTS when added to a traditional CTS physical therapy program.

Short-term recovery after implant versus resection arthroplasty in trapeziometacarpal joint osteoarthritis.

We compared the short-term recovery of patients treated with trapeziometacarpal joint (TMJ) implant arthroplasty versus resection-suspension-interposition (RSI) arthroplasty. Implant patients (n = 147) had a better 3-month postoperative brief Michigan Hand Outcomes Questionnaire (MHQ) score (mean 82) compared to RSI patients (n = 127), who had a mean score of 69. Key pinch strength at 3 months was also higher in the implant group compared to the RSI group (6.8 kg vs. 3.1 kg). At 1 year, both groups had similar brief MHQ scores, but key pinch remained higher in the implant group (7.0 kg vs. 3.9 kg [RSI]). After implant arthroplasty, employed patients returned to work after a mean of 44 days, which was significantly faster than the 84 days for RSI patients. Patients after TMJ implant arthroplasty recover significantly faster in the first 3 postoperative months compared to RSI patients. However, 1-year postoperative outcomes are similar for both cohorts, with key pinch strength remaining higher for patients with TMJ implant arthroplasty.Level of evidence: II.
