Unravelling a hidden pathology of a vertebral fracture in a teenage girl

BackgroundAlthough the skeleton remains a common target of primary hyperparathyroidism, the classic bone disease “osteitis fibrosa cystica” is currently rare due to early diagnosis. This case represents severe classic bone manifestations of primary hyperparathyroidism due to delayed diagnosis and delayed medical attention.Case presentationA 19-year-old young female was symptomatically managed for chronic back pain and nonspecific bone pain in the small joints of both hands over 2 months by a general practitioner. The patient had delayed seeking for treatment for 3 months. Later, she was evaluated for tuberculosis, hematological malignancies and rheumatic disorders following a fractured T12 vertebra and underwent pedicle screw fixation. However, clinical examination and investigations, including biochemistry, imaging and histology, ruled out the above conditions. Unfortunately, serum calcium level was not performed at the initial presentation. Later, primary hyperparathyroidism was diagnosed on the basis of moderate hypercalcaemia and elevated intact PTH levels (2064 pg/ml). She had sufficient vitamin D levels and normal kidney function. Her DXA scan revealed severe secondary osteoporosis with the lowest Z score of -8 at the total lumbar spine. Ultrasonography of the thyroid revealed a hypo echoic mass in the left lower neck, and localization studies with technetium-99 m sestamibi and 4D-CT revealed a left inferior parathyroid adenoma (1.6 × 1.5 × 1.6 cm). CT scan also revealed brown tumors in the mandible and vertebrae and diffuse bony changes in the skull, sternum, humerus and vertebrae. Her radiographs revealed subperiosteal bone resorption on the radial aspects of the middle and distal phalanges and brown tumors in both the ulna and fibula. We excluded MEN and other hereditary syndromes in our patient with a personal and family history and with a normal pituitary hormone profile because of poor resources for genetic testing. She underwent parathyroid adenoma excision, and the postoperative period was complicated with hungry bone syndrome, requiring high doses of calcium and active vitamin D supplements. These supplements were gradually weaned off over 6 months, and she recovered with normal biochemical investigations. Histology revealed parathyroid adenoma without malignant features.ConclusionIn developing countries where routine calcium screening is not available, clinicians should be aware of various manifestations of primary hyperparathyroidism to allow diagnosis as soon as possible without delay to prevent further progression, as it is a treatable condition.

The Efficacy of Triple Shoulder Injection with Steroids and Ozone in the Treatment of Chronic Shoulder Pain and Range of Motion Limitation

Objective: This study aimed to evaluate and compare the therapeutic effects of fluoroscopy-guided triple shoulder injections with steroids and, a combination of steroids and ozone. Methods: Data were retrospectively collected from the files of 70 patients diagnosed with non-specific chronic shoulder pain and received triple shoulder injections. The patients were divided into two groups. One group included triple shoulder injections with steroids under fluoroscopic guidance, while the other group included combination of steroids and ozone. Pain intensity was evaluated with the Visual Analog Scale (VAS), the patient's quality of life and functionality were assessed using the Shoulder Pain and Disability Index (SPADI), and the active range of motion (ROM) of shoulder abduction, external rotation, and flexion were measured by goniometry. Beck Depression Inventory (BDI) was used to measure the severity of depression before the procedure. All measurements were recorded at baseline and 1, 3, and 6 months after the procedure. Results: Baseline characteristics were similar in both groups. There was no statistical difference in VAS scores between the two groups at baseline, 1st, and 3rd months. However, in the 6th months, the VAS scores of patients treated with steroids plus ozone were significantly lower than those of patients treated with steroids (P<0.001). Both groups showed significant improvements in SPADI pain, disability, and total subscores compared to pre-treatment values (P < 0.001). There was a significant improvement in the ROM of the shoulder joint in both groups (p<0.001). However, patients who received ozone and steroid treatments showed a significantly greater increase in SPADI and ROM of shoulder joints in the 6th months (p<0.001). There was a positive correlation between BDI score and pain duration, and the severity of depression had no statistically significant effect on VAS scores. Conclusion: Results of this study revealed that triple shoulder injection with steroids or a combination of steroids and ozone proved to be an effective therapeutic approach for patients suffering from shoulder pain and limited mobility. The combination of ozone with steroids may lead to better results than using steroids alone. Furthermore, a long duration of pain increases the risk of chronic depression in patients.

Cognitive Behavioral Therapy for Insomnia in Pain Management for Nonspecific Chronic Spinal Pain

Insomnia is highly prevalent in patients with nonspecific chronic spinal pain (nCSP). Given the close interaction between insomnia and pain, targeting sleep problems during therapy could improve treatment outcomes. To evaluate the effectiveness of cognitive behavioral therapy for insomnia (CBTi) integrated in best-evidence pain management (BEPM) vs BEPM only in patients with nCSP and insomnia. A multicenter randomized clinical trial with 1-year follow-up was conducted between April 10, 2018, and April 30, 2022. Data and statistical analysis were performed between May 1, 2022, and April 24, 2023. Patients with nCSP and insomnia were evaluated using self-report and at-home polysomnography, to exclude underlying sleep pathologic factors. Participants were treated at the University Hospital Brussels or University Hospital Ghent, Belgium. Intention-to-treat analysis was performed. Participants were randomized to either CBTi-BEPM or BEPM only. Both groups received 18 treatment sessions over 14 weeks. The CBTi-BEPM treatment included 6 CBTi sessions and 12 BEPM sessions. The BEPM treatment included pain neuroscience education (3 sessions) and exercise therapy (9 sessions in the CBTi-BEPM group, 15 sessions in the BEPM-only group). The primary outcome was change in mean pain intensity (assessed with Brief Pain Inventory [BPI]) at 12 months after the intervention. Exploratory secondary outcomes included several pain- and sleep-related outcomes. Blinded outcome assessment took place at baseline, posttreatment, and at 3-, 6-, and 12-month follow-up. A total of 123 patients (mean [SD] age, 40.2 [11.18] years; 84 women [68.3%]) were included in the trial. In 99 participants (80.5%) with 12-month BPI data, the mean pain intensity at 12 months decreased by 1.976 points (reduction of 40%) in the CBTi-BEPM group and 1.006 points (reduction of 24%) points in the BEPM-only group. At 12 months, there was no significant difference in pain intensity change between groups (mean group difference, 0.970 points; 95% CI, -0.051 to 1.992; Cohen d, 2.665). Treatment with CBTi-BEPM resulted in a response for BPI average pain with a number needed to treat (NNT) of 4 observed during 12 months. On a preliminary basis, CBTi-BEPM was, consistently over time and analyses, more effective than BEPM only for improving insomnia severity (Cohen d, 4.319-8.961; NNT for response ranging from 2 to 4, and NNT for remission ranging from 5 to 12), sleep quality (Cohen d, 3.654-6.066), beliefs about sleep (Cohen d, 5.324-6.657), depressive symptoms (Cohen d, 2.935-3.361), and physical fatigue (Cohen d, 2.818-3.770). No serious adverse effects were reported. In this randomized clinical trial, adding CBTi to BEPM did not further improve pain intensity reduction for patients with nCSP and comorbid insomnia more than BEPM alone. Yet, as CBTi-BEPM led to significant and clinically important changes in insomnia severity and sleep quality, CBTi integrated in BEPM should be considered in the treatment of patients with nCSP and comorbid insomnia. Further research can investigate the patient characteristics that moderate the response to CBTi-BEPM in terms of pain-related outcomes, as understanding of these moderators may be of utmost clinical importance.

Exploring the Real-Time Variability and Complexity of Sitting Patterns in Office Workers with Non-Specific Chronic Spinal Pain and Pain-Free Individuals.

Chronic spinal pain (CSP) is a prevalent condition, and prolonged sitting at work can contribute to it. Ergonomic factors like this can cause changes in motor variability. Variability analysis is a useful method to measure changes in motor performance over time. When performing the same task multiple times, different performance patterns can be observed. This variability is intrinsic to all biological systems and is noticeable in human movement. This study aims to examine whether changes in movement variability and complexity during real-time office work are influenced by CSP. The hypothesis is that individuals with and without pain will have different responses to office work tasks. Six office workers without pain and ten with CSP participated in this study. Participant's trunk movements were recorded during work for an entire week. Linear and nonlinear measures of trunk kinematic displacement were used to assess movement variability and complexity. A mixed ANOVA was utilized to compare changes in movement variability and complexity between the two groups. The effects indicate that pain-free participants showed more complex and less predictable trunk movements with a lower degree of structure and variability when compared to the participants suffering from CSP. The differences were particularly noticeable in fine movements.

Effects of Wrist Stability Training Combined with Grip Strength Exercise on Pain and Function in Patients with Nonspecific Chronic Wrist Pain.

Background and Objectives: Non-specific chronic wrist pain is wrist pain that occurs without a specific cause, such as trauma, and may limit the range of motion of the joints of the wrist and hand, affecting muscle strength, grip strength, and function. This study aimed to determine the effects of grip-strengthening exercises combined with wrist stability training on pain and function in patients with non-specific chronic wrist pain. Materials and Methods: The subjects of the study were 31 patients with wrist pain. To determine the effect of grip-strengthening exercises combined with wrist stability training, 15 participants participated in grip-strengthening exercises combined with wrist stability training and 16 control subjects participated. The experimental group participated in wrist-stability training. Grip-strengthening exercises combined with wrist stability training were performed for 20 min/day twice a week for 4 weeks, and relaxation massage and conservative physical therapy were performed for 20 min/day twice a week for 4 weeks. The control group received relaxation massage and conservative physical therapy for 40 min/day twice a week for 4 weeks. A visual pain scale was used to evaluate the degree of pain before and after treatment, and a patient-rated wrist evaluation was used to evaluate wrist function. Results: The results showed that the visual score significantly decreased in the time effect before and after the intervention in both groups (p < 0.001), patient-rated wrist evaluation significantly decreased (p < 0.001), and grip strength and muscle strength significantly increased (p < 0.001). The results of this study showed that grip-strengthening exercises combined with wrist stability training were effective in improving pain, function, grip strength, and muscle strength in patients with non-specific chronic wrist pain. Conclusions: Grip-strengthening exercises combined with wrist stability training can be used as an effective intervention method to improve pain, function, grip strength, and muscle strength, emphasizing the need for wrist exercise interventions in patients with non-specific chronic wrist pain in the future.

Clinical Impact of Thermotherapy and Spinal Twisting Massage on Chronic Non-Specific Spinal Pain.

As the prevalence of chronic non-specific spinal pain rises, the utilization of diverse massage devices for therapeutic intervention increases rapidly. However, research on their mechanisms, particularly those involving spinal twisting, is limited. This study was designed to evaluate the impact of heat application and spinal twisting massage techniques on individuals suffering from chronic non-specific spinal pain. A total of 36 individuals were divided into two groups: a control group (18 participants) and an experimental group (18 participants). The experimental group received heat treatment plus spinal twisting massage twice a week for four weeks, while the control group received heat therapy plus traditional vibration massage techniques. Effectiveness was measured using the Visual Analog Scale (VAS), the Pressure Pain Threshold (PPT), the Korean Western Ontario and McMaster Universities (K-WOMAC) Index, spine tilt, and Cobb angle. VAS, K-WOMAC, and PPT significantly improved in both groups at all three time points. VAS notably decreased in the experimental group compared to the control group (p-value: 0.0369). Despite improvements in K-WOMAC and PPT scores within the experimental group, statistical significance remained elusive. Furthermore, spine tilt and Cobb angle showed no significant differences from baseline to the 6th week. In conclusion, the application of thermotherapy coupled with twisting massage demonstrates significant efficacy in mitigating chronic non-specific spinal pain, surpassing the pain-relief outcomes achieved through heat therapy in combination with standard vibration massage techniques.

The application of directional preference for chronic non-specific knee pain: A pragmatic, controlled, randomized clinical trial

Functional disability and chronic knee pain are frequent in combats sports participants. The McKenzie Method of Mechanical Diagnosis and Therapy (MDT) is a system for specific function examination and intervention for spinal and extremity musculoskeletal disorder. This clinical trial aimed to investigate the effectiveness of MDT, through Directional Preference, for specific function disability in Brazilian Jiu-Jitsu practitioners (BJJPs) experiencing chronic non-specific knee pain. MethodsSixty-five BJJPs with chronic non-specific knee pain were evaluated and classified according to the MDT system. Following classification, 28 BJJPs were randomized pairwise into intervention (IG) and control (CG) groups. The procedures were consistent with the principles of DP and the intervention period was 6 weeks and follow up was included. The primary outcome was specific functional disability evaluated using the Patient Specific Function Scale (PSFS) and the secondary outcomes were pain intensity and fear-avoidance in utilizing the symptomatic limb. Data were analyzed with a two-way analysis of variance (ANOVA) and repeated measures for the outcome factor were performed (p < 0.05). ResultsFor the specific functional disability, ANOVA revealed significant differences between groups based on group interaction and treatment factors (F (2, 52): 162,015; p < 0.001; η2: 0.208). The BJJPs allocated to the IG achieved significant improvements in specific functional disability, a mean difference of −4.36 (−5.01 to −3.72) post-interventional and −4.80 (−6.07 to −3.53) follow-up in the PSFS. Improvements in pain intensity and fear-avoidance were also achieved post-intervention and follow-up. ConclusionIntervention in accordance with DP promoted resulted in favorable outcomes for clinical effects on specific functional disability pain intensity, and symmetry index of the lower limbs. These findings suggest that intervention based on DP may be effective in the management of chronic knee pain in BJJPs.

Chronic nonspecific multiple-sites pain [CNMSP] of unknown etiology: Biopsychosocial method of evaluation for the primary care level.

Understanding and dealing with chronic nonspecific pain (CNP) is the important entity at primary care hospital. Chronic nonspecific multiple-site pain [CNMSP] of unknown etiology creates diagnostic and therapeutic challenges for primary care physicians due to lack of guidance regarding evaluation and treatment. To classify and formulate the evaluation, treatment strategies, and prediction of prognosis of patients with CNMSP of unknown etiology. Patients present with CNMSP of more than 3-month duration without any obvious medical cause. The biopsychosocial [BPS] model with 3P model was applied to see the biological, psychological, and social factors behind persistence. Finally, patients were classified into four groups for evaluation response to treatment and relapse rates in 12-month follow-up. Of the total 243 patients of CNMSP, 243 [96.3%] were females. Sixty [24.7%] patients had short duration, and 183 [75.3%] had long duration. Headache was in 115 [47%], low back pain ± leg pain in 96 [39.4%], cervical pain ± shoulder/arm pain in 83 [34.1%], and diffuse body pain in 50 [20.5%] in various combinations. A total of 155 [63.8%] patients had high somatization-sensitization index (SSI), and 144 [59.3%] had low ferritin level. Group 1 [high SSI and low ferritin] had 37.9% of patients, group 2 [high SSI and normal ferritin] had 25.9% of patients, group 3 [low to medium SSI with low ferritin] had 21.4% of patients, and group 4 [low to medium SSI with normal ferritin] had 14.8% of patients. Response to pain symptoms was better in group 1, and relapse rate was higher in group 2. CNMSP of unknown etiology itself is a heterogeneous entity, and assessment based on the BPS model can be very useful to understand the treatment plan and outcome of these patients.

The Role of Anxiety and Depression in Shaping the Sleep-Pain Connection in Patients with Nonspecific Chronic Spinal Pain and Comorbid Insomnia: A Cross-Sectional Analysis.

(1) Background: This exploratory study aims to explore the relationship between nonspecific chronic spinal pain (nCSP) and insomnia symptoms, by examining the interconnections, strengths, and directional dependence of the symptoms. In addition, we aim to identify the key symptoms of the nCSP-insomnia relationship and shed light on the bidirectional nature of this relationship. (2) Methods: This study is a secondary analysis of the baseline data (cross-sectional) from a randomized controlled trial, which examined the added value of Cognitive Behavioral Therapy for Insomnia (CBT-I) combined with cognition-targeted exercise therapy, conducted in collaboration with the Universiteit Gent and Vrije Universiteit Brussel (Belgium). One hundred and twenty-three nCSP patients with comorbid insomnia were recruited through the participating hospitals, advertisements, announcements in local newspapers, pharmacies, publications from support groups, and primary care. To explore the interconnections and directionality between symptoms and the strengths of the relationships, we estimated a regularized Gaussian graphical model and a directed acyclic graph. (3) Results: We found only one direct, but weak, link between sleep and pain, namely, between average pain and difficulties maintaining sleep. (4) Conclusions: Despite the lack of strong direct links between sleep and pain, pain and sleep seem to be indirectly linked via anxiety and depression symptoms, acting as presumable mediators in the network of nCSP and comorbid insomnia. Furthermore, feeling slowed down and fatigue emerged as terminal nodes, implying their role as consequences of the network.

Adaptation and validation of the west haven-yale multidimensional pain inventory for Pakistani population.

To evaluate the adapted version of West Haven-Yale Multidimensional Pain Inventory for patients with chronic pain. The multiphase study was conducted from January to December 2021. The factorial structure of the Urdu version of West Haven-Yale Multidimensional Pain Inventory was evaluated on a sample of adult patients aged 18- 45 years with non-specific chronic pain, taken from public and private hospitals and clinics of Lahore, Pakistan. The Urdu version was then subjected to factor analysis, while Cronbach's alpha, composite reliability, convergent and discriminant validity of the scale were also calculated. Data was analysed using SPSS 24. Of the 306 subjects, 204(66.7%) were females and 102(33.3%) were men. The overall mean age was 30.94+/-8.44 years. There were 166(54.2%) subjects who were married, and 137(44.8%) reported experiencing pain daily. The confirmatory factor analysis showed a 45-item structure for 12 sub-scales as the best fit. The statistics for the final model were observed as minimum discrepancy function by degrees of freedom divided was 1.69, root mean square error of approximation was 0.05, and standardised root mean square residual was 0.06. Comparative fit index value was 0.91 and Tucker-Lewis coefficient was 0.90. Cronbach's alpha reliability ranged between 0.68 and 0.89 for the subscales, while for the total scale, it was 0.72. The Urdu version of West Haven-Yale Multidimensional Pain Inventory was found to be a reliable and valid tool for chronic pain assessment for patients in Pakistan.

Exploring Interactions Between Sex, Pain Characteristics, Disability, and Quality of Life in People With Chronic Spinal Pain: A Structural Equation Model

In people with nonspecific chronic spinal pain (nCSP), disability and quality of life are associated with clinical, cognitive, psychophysical, and demographic variables. However, evidence regarding the interactions between these variables is only limited to this population. Therefore, this study aims to explore path models explaining the multivariate contributions of such variables to disability and quality of life in people with nCSP. This secondary analysis uses baseline data from a randomized controlled trial including 120 participants with nCSP. Structural equation modeling was used to explore path models for the Pain Disability Index (PDI), the Short Form 36-item physical (SF-36 PC), and mental (SF-36 MC) component scores. All models included sex, pain catastrophizing, kinesiophobia, hypervigilance, and pain intensity. Additionally, the PDI and SF-36 PC models included pressure pain thresholds (PPTs) at the dominant pain site (ie, neck or low back). Significant associations were found between sex, pain cognitions, pain intensity, and PPTs. Only pain catastrophizing significantly directly influenced the PDI (P ≤ .001) and SF-36 MC (P = .014), while the direct effects on the SF-36 PC from kinesiophobia (P = .008) and pain intensity (P = .006) were also significant. However, only the combined effect of all pain cognitions on the SF-36 PC was mediated by pain intensity (P = .019). Our findings indicate that patients’ pain-related cognitions have an adverse effect on their physical health-related quality of life via a negative influence on their pain intensity in people with nCSP. PerspectiveThis secondary analysis details a network analysis confirming significant interactions between sex, pain cognitions, pain intensity, and PPTs in relation to disability and health-related quality of life in people with chronic spinal pain. Moreover, its findings establish the importance of pain cognitions and pain intensity for these outcomes. Trials registrationClinicaltrials.gov (NCT02098005).

Pain-Related Stigma and Its Associations With Clinical and Experimental Pain Severity in Youth With Chronic Musculoskeletal Pain Conditions.

Many children with chronic musculoskeletal pain conditions experience stigma which can have negative downstream consequences. This study compares ratings of clinical pain (current pain intensity and pain interference), experimental pain (temporal summation, cold water tolerance, and cold pain intensity), and pain-related stigma among three groups of youth with rheumatic conditions. The relations among ratings of pain-related stigma and pain variables were explored. Eighty-eight youth aged 8-17 years with a diagnosis of juvenile idiopathic arthritis (JIA = 32), juvenile fibromyalgia (JFM = 31), or non-specific chronic pain (NSCP = 25) completed measures of clinical pain ratings (average 7-day pain intensity, day of assessment pain (DoA), and pain interference), experimental pain (cold pain tolerance, cold pain intensity, and temporal summation of mechanical pain), and pain-related stigma. Data analysis compared pain-related stigma and pain ratings across the three groups and examined the relations among pain-related stigma and pain ratings. Youth with JFM reported higher ratings of clinical pain and pain-related stigma than their counterparts with NSCP or JIA. However, there were no differences in experimental pain. Pain-related stigma was associated with greater ratings of pain interference, particularly for those with JIA and NSCP. Pain-related stigma was also associated with greater average daily pain intensity but not DoA. Youth with medically unexplained pain report greater stigma and worse pain than their peers; thus, robust assessment of pain in this population is necessary. Future work should longitudinally explore the impact of pain-related stigma on pain outcomes and treatment responses.

Investigating the Effects of Retro Walking on Pain, Physical Function, and Flexibility in Chronic Non-specific Low Back Pain

Objectives: Chronic non-specific low back pain (CNSLBP) is described as pain whose pathoanatomical cause cannot be determined. The current study aims to evaluate the impact of retro-walking on pain, flexibility, and physical functions in patients with CNSLBP. Methods: A randomized controlled trial was conducted in the Physical Therapy Department of District Head Quarter Hospital Nankana Sahib, Punjab, Pakistan from September 2021 to March 2022. The trial was conducted on 36 patients, randomly divided into 2 groups of 18 patients. Conventional treatment and retro-walking were given to the experimental group and the conventional treatment alone was provided to the control group for 1 month with 3 sessions per week. The outcome variables were pain, the flexibility of hamstrings and lumbar region, and physical function assessed by numeric pain rating scale, sit and reach test, modified Schober test, and modified Oswestry disability index, respectively. The data were assessed at pre-treatment after the sixth and twelfth sessions. Results: This study showed a significant difference in the numeric pain rating scale, sit-and-reach test, and modified Oswestry disability index with a P&lt;0.05 in both groups after intervention. However, in the group comparison, these variables showed better results in the retro-walking group compared to others with a P&lt;0.001 after both the sixth and twelfth sessions. Discussion: The current study suggested that when added up to conventional treatment, retro-walking was more beneficial in reducing pain and enhancing the flexibility and physical function in patients with CNSLBP when compared to conventional treatment alone; therefore, it should be added to the treatment protocol for chronic non-specific pain in the lower back.

Análisis sobre la prescripción de benzodiazepinas por médicos de familia en una muestra en Río de Janeiro

This qualitative study researched the determinants influencing family physician’s decision on benzodiazepine prescription in a primary care setting, in the city of Rio de Janeiro. An analysis was sought to be elaborated, on how the prescription is negotiated between physician and user. Twelve general practitioners settled in primary care were recruited, gave acceptance signing free and informed consent form, responding to a semi-structured questionnaire that was recorded and transcribed verbatim for analysis, from August to December 2017. The questionnaire addressed physicians' perception of complaints in benzodiazepines users, and alternatives offered instead of medicines. Anxiety and insomnia were cited as the most frequent reasons for use. There was also mention of nonspecific somatic complaints, chronic pain, arterial hypertension, and dependence. Most physicians proposed the therapeutic alliance as a mechanism for offering alternatives to reduce the chronic use of benzodiazepines, despite this intervention achieving a low success rate. Longitudinal care was evidenced as a guiding principle. The analysis of the meanings attributed to BZD, as unveiled in this work, promotes a discussion about the place of medication in culture and its consequences in the approach to psychological and mental suffering.

Skeletal Muscle and Fat Mass Reflect Chronic Pain in Older Adult.

Objectives: The prevalence of chronic pain increases with age. It has been reported that chronic pain is associated with sarcopenia and obesity. Age-related skeletal muscle loss and fat gain are known to occur due to chronic inflammation. The aim of this study was to analyze how skeletal muscle and fat, caused by chronic inflammation due to aging, regulate the development of geriatric chronic pain. Methods: The results of skeletal muscle and fat mass, 412 participants aged ≥65 years with non-specific chronic pain lasting ≥6 months, including low back, neck, and knee pain, was compared with the control without chronic pain. Body composition threshold regulating chronic pain was calculated. Results: A significantly lower skeletal muscle mass index and higher body fat percentage were observed in patients with chronic pain than that in the control. The muscle fat ratio (MFR) was significantly lower in the chronic pain group than in the control group. When the MFR threshold related to chronic pain was calculated by sex, it was 2.984 for men and 1.867 for women. Conclusions: Evaluation of the body composition of elderly patients with non-specific chronic pain revealed that the MFR was useful as an index related to chronic pain.

Efficacy of Low-Level Laser Therapy for the Treatment of Nonspecific Chronic Neck Pain: Low-Level Laser Therapy vs. Sham Laser.

Introduction: The most common type of neck pain is chronic nonspecific pain. There are conflicting opinions about the beneficial effects of a low-level laser in reducing chronic nonspecific neck pain. The aim of this study was to evaluate the efficacy of low-level laser therapy (LLLT) for the treatment of non-specific chronic neck pain. Methods: This study was conducted as a prospective randomized clinical trial. Forty-four patients were randomly divided into two groups: (1) Intervention group (n=22): LLLT in the red spectra range with a wavelength of 980 (nm) and a power of 16 (J/cm2 ) was irradiated in the affected areas of the neck, the muscles along the spine, and the upper trapezius; (2) sham group (n=22): A low-level laser was irradiated with a passive probe (non-laser red light) in the affected areas of the neck, the muscles along the spine, and the upper trapezius. The treatment protocol consisted of 12 sessions (15 minutes, three times a week, for four weeks). These patients were evaluated for pain using the visual analog scale (VAS) (0-10). The patients were followed up for four weeks. Results: This study showed a statistically significant reduction in chronic nonspecific neck pain in the LLLT group (P<0.05). Conclusion: It is concluded that LLLT was effective in reducing chronic nonspecific neck pain. LLLT is a non-invasive, safe and effective method that can improve chronic nonspecific neck pain in patients in the short term.

The condition of the erector spinae muscle in patients with chronic nonspecific low back pain

Myofascial pain syndrome caused by damage to the paravertebral muscles is considered as one of the causes of chronic back pain. At the same time, there is not enough information about the condition of the paravertebral muscles, and it is contradictory.The aim of the work is to elucidate the presence and severity of structural and functional changes in the paravertebral muscles and their role in the development of chronic nonspecific pain in the lower back in women.Material and methods. Morphological, immunohistochemical examination of a muscle tissue biopsy was performed in 17 patients aged 24 to 59 years (average age — 41.5 ± 12.1 years) with CNS (average duration of pain syndrome 10.0 ± 6.9 months) caused by myofascial pain syndrome, as well as determination by gel electrophoresis of the isoform composition of giant sarcomeric proteins titin and nebulin.Results. Morphological examination revealed no signs of necrosis, proliferation of connective and adipose tissue, inflammatory infiltration. The transformation of the myosin phenotype in the direction of an increase in the proportion of “fast” type II muscle fibers was revealed in the biopsies of the patients’ muscles. A decrease in the content of giant titin and nebulin proteins associated with myosin and actin in the sarcomere was also found.Conclusion. The data obtained indicate a violation of the contractile function of the paravertebral muscle in CNS.

Relationship between Pain Intensity, Physical Factors, Pronociceptive Pain Modulation Profile and Psychological Vulnerability on Upper Limb Disability in Older Patients with Chronic Shoulder Pain.

Chronic shoulder pain is a very prevalent condition causing disability and functional impairment. The purpose of the study was to evaluate the relationship between pain intensity, physical variables, psychological vulnerability, pronociceptive pain modulation profile and disability in older people with chronic shoulder pain. A cross-sectional study was carried out. A total of 56 participants with non-specific chronic shoulder pain of the "Complejo Hospitalario Universitario" (Granada) and 56 healthy controls were included. The outcomes evaluated were pain intensity (visual analogue scale), physical factors (dynamometry for grip strength), psychological vulnerability (Fear-Avoidance Beliefs Questionnaire and Tampa Scale of Kinesiophobia), pronociceptive pain modulation profile (pain pressure algometry) and disability (Quick Disability Arm Shoulder Hand questionnaire). Disability showed a positive correlation with pain and psychological vulnerability (p &lt; 0.05) and a negative correlation with pronociceptive pain variables and dynamometry (p &lt; 0.001). Psychological vulnerability also presented a strong negative correlation with proprioceptive pain variables and dynamometry and a positive correlation with pain (p &lt; 0.05). In regard to the pronociceptive pain modulation profile, a strong negative correlation with pain (p &lt; 0.001) and a positive moderate correlation with dynamometry (p &lt; 0.001) were shown. Our results support a strong association between disability, psychological vulnerability and pronociceptive pain modulation profile in older adults with chronic shoulder pain.
