Abstract
Numerous research studies have delved into the potential effect of LASER therapy on alleviating pain associated with plantar fasciitis. However, the distinct effects of both High Intensity and Low Intensity LASER therapy (HILT/LILT) on addressing plantar fasciitis pain have not been thoroughly investigated. This systematic review seeks to provide a comprehensive summary of the present body of literature regarding the use of LASER therapy in managing pain related to plantar fasciitis. A conscientious search across four databases namely Google Scholar, PubMed, PEDro and The Cochrane Library was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, which yielded five pertinent studies out of 21,034 studies that met the predefined inclusion criteria and underwent rigorous evaluation. The assessment tools such as PEDro were employed on these studies for critical review. Although some variations persisted among the research outcomes, a predominant trend highlighted a notable decrease in pain severity on Visual Analogue Scale (VAS)/Numeric Rating Scale-pain (NRS-p) with the adoption of diverse LASER therapy methodologies. Notably, no adverse repercussions were reported across any of the studies, emphasizing the safety profile of these LASER interventions for plantar fasciitis patients. In summation, integrating these LASER therapy approaches alongside conventional therapeutic strategies appears promising for enhancing the efficacy and sustainability of plantar fasciitis pain management. The study protocol has been registered with PROSPERO (CRD42023453098) (International Prospective Register of Systematic Reviews).

Abstract
INTRODUCTION Upper quadrant musculoskeletal disorders (UQMD), comprising of cranial, cervical, shoulder and upper extremity disorders, are among the most frequently reported disorders in clinical practice. Thoracic high velocity low amplitude thrust (Tx-HVLAT) manipulation is a form of conservative management recommended in systematic reviews as an effective treatment option for aspects of UQMD disorders such headache, shoulder pain and lateral elbow pain. However, no recent systematic reviews have assessed the effectiveness across UQMD. Therefore, this systematic review aims to update the current evidence on the effectiveness of Tx-HVLAT for patients with UQMD on (1) patient-reported outcomes, (2) performance measures or (3) psychosocial outcomes. METHODS AND ANALYSIS The Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PEDro and Index to Chiropractic Literature will be searched from inception using Medical Subject Headings (MeSH), Thesaurus and/or free-text words. Combinations will be made based on localisation, disorder, intervention and design. Following guidelines as advised by the Cochrane Back Review Group, published randomised controlled trials will be included. Two review authors will independently assess the risk of bias (ROB) using the Cochrane Back Review Group's recommended ROB2 tool and will independently extract the data using a standardised data extraction form. Overall quality of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) method. For continuous data, we will calculate standardised mean differences with 95% CIs. For dichotomous outcomes, relative risks and 95% CIs will be calculated. Where possible we will present a subgroup analysis by disorder. For pooling, a random-effects model will be used. ETHICS AND DISSEMINATION Ethics approval is not required for this systematic review. The study findings will be submitted to a relevant peer-reviewed journal for dissemination and presented at relevant conferences. PROSPERO REGISTRATION NUMBER CRD42023429996.

JOURNAL OF RHEUMATIC DISEASES 2023; 30:170-175. [PMID: 37476675 PMCID: PMC10351370 DOI: 10.4078/jrd.2023.0004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/18/2023] [Accepted: 05/30/2023] [Indexed: 07/22/2023]
Abstract
Objective The objective of this study was to evaluate the safety and efficacy of light-emitting diode therapy (LEDT) in the management of pain and stiffness in patients with refractory hand tenosynovitis to non-steroidal anti-inflammatory drugs. Methods A total of 12 patients were enrolled in the study and received LEDT twice a week for four weeks. Sociodemographic, clinical, and laboratory data were collected, and the visual analog scale (VAS) pain and stiffness scores of each hand were assessed every two weeks. The thickness of the flexor tendon in the patients' hand was evaluated using ultrasonography. To investigate the molecular effects of LEDT, we measured the expression levels of type III collagen in tendon cells, with and without LEDT treatment. Results After undergoing LEDT, participants showed clinically significant improvements in VAS pain scores at weeks 2, 4, and 8 compared to their baseline, and in VAS stiffness scores at weeks 4 and 8. According to the ultrasonography results, there was a decreasing tendency in tendon thickness for each finger in week 8 compared to the baseline, but the difference was not statistically significant. No adverse events were reported. Additionally, our results indicated a significant increase in type III collagen levels in the LEDT group compared to the control group (1.48±0.18 vs. 0.99±0.02, p=0.031), indicating a potential molecular mechanism for the observed clinical improvements. Conclusion LEDT may provide a viable alternative to pharmacological treatments in the future, due to its simple and easy method of administration.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18157733. [PMID: 34360027 PMCID: PMC8345749 DOI: 10.3390/ijerph18157733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/13/2021] [Accepted: 07/18/2021] [Indexed: 11/26/2022]
Abstract
The course of the posterior antebrachial cutaneous nerve (PACN) was studied via ultrasound (US) and dissection. The aim of this study was to reveal the anatomical relationships of PACN with the surrounding structures along its pathway to identify possible critical points of compression. Nineteen cryopreserved cadaver body donor upper extremities were explored via US and further dissected. During US exploration, two reference points, in relation with the compression of the nerve, were marked using dye injection: (1) the point where the RN pierces the lateral intermuscular septum (LIMS) and (2) the point where the PACN pierces the deep fascia. Anatomical measurements referred to the lateral epicondyle (LE) were taken at these two points. Dissection confirmed the correct site of US-guided dye injection at 100% of points where the RN crossed the LIMS (10.5 cm from the LE) and was correctly injected at 74% of points where the PACN pierce the deep fascia (7.4 cm from the LE). There were variations in the course of the PACN, but it always divided from the RN as an only branch. Either ran close and parallel to the LIMS until the RN crossed the LIMS (84%) or clearly separated from the RN, 1 cm before it crossed the LIMS (16%). In 21% of cases, the PACN crossed the LIMS with the RN, while in the rest of the cases it always followed in the posterior compartment. A close relationship between PACN and LIMS, as well as triceps brachii muscle and deep fascia was observed. The US and anatomical study showed that the course of PACN maintains a close relationship with the LIMS and other connective tissues (such as the fascia and subcutaneous tissue) to be present in its pathology and treatment.

Musculoskelet Sci Pract 2021; 52:102347. [PMID: 33618232 DOI: 10.1016/j.msksp.2021.102347] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 02/02/2021] [Accepted: 02/06/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Routine utilisation of outcome measures (OMs) is an integral part of physiotherapy rehabilitation when managing non-specific neck pain (NSNP). Numerous relevant OMs exist; however, the extent to which OMs are used by physiotherapists in the UK for NSNP is unknown. OBJECTIVE To determine current utilisation patterns of OMs in UK physiotherapy practice when managing NSNP. METHODS An online web-based survey instrument was developed and physiotherapists were invited to participate if they were currently practicing in the UK and had some experience of managing patients with neck pain. Logistic regression analyses using the generalised linear models was carried out to identify characteristics associated with OMs utilisation. RESULTS A total of 2101 surveys were completed. One-third of the respondents reported not using OMs when managing NSNP. Lack of time and clear guidance about the suitability of available OMs were the most commonly reported reasons. A majority of the two-thirds of those who reported using OMs were consistently using pain and range of motion rating measures. Physical/functional limitations, psychological distress, and quality of life constructs, which are frequently associated with NSNP, were rarely measured. Years of practice (p = 0.000), nation (p = 0.019) and proportion of patients with neck pain (p = 0.034) variables were found to be independently associated with frequent use of OMs. CONCLUSION This survey established the poor integration of OMs in the UK when managing NSNP. Further attention is required to identify or develop OMs which are feasible for use in busy clinical practice and to market them more effectively to physiotherapists.

Measuring upper limb disability for patients with neck pain: Evaluation of the feasibility of the single arm military press (SAMP) test. Musculoskelet Sci Pract 2020; 50:102254. [PMID: 32932051 DOI: 10.1016/j.msksp.2020.102254] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Revised: 08/27/2020] [Accepted: 09/01/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND Non-specific neck pain (NSNP) is frequently associated with upper limb disability (ULD). Consequently, evaluation of ULD using an outcome measure is necessary during the management of patients with NSNP. The Single Arm Military Press (SAMP) test is a performance-based ULD measure developed for populations with neck pain. During the SAMP test, patients are asked to repeatedly lift a weight above their head for 30 s. The number of repetitions is counted. Its clinical utility in a patient group is still unknown. OBJECTIVE This study investigates the feasibility of the SAMP test from patients and clinicians' perspectives. METHODS Seventy female patients with NSNP were randomly allocated into one of three groups. Participants in each group completed the SAMP test using one of three proposed weights (½kg, 1 kg or 1½kg). The feasibility of the SAMP test was established using structured qualitative exit feedback interviews for patients and administrating clinicians. RESULTS Participants using ½kg achieved the highest number of repetitions, but a high proportion reported the weight as extremely light, whereas those who tested using the 1½kg achieved the lowest number of repetitions and participants reported the weight as being heavy. Participants tested using 1 kg achieved an average number of repetitions and a high proportion reported the weight as acceptably heavy. Clinicians and patients reported that the SAMP test was efficient and convenient. CONCLUSION The 1 kg SAMP test is feasible for use in female patients with NSNP. The measurement properties of the SAMP test should be determined in a patient group.

Abstract
OBJECTIVE To investigate the association and the exposure-response relationship between work above shoulder height and shoulder pain or disorders. METHODS A systematic search was performed in Medline, Embase, and Health and Safety Science Abstracts. Included were articles with prospective cohort, case-control, cross-sectional, or intervention study designs. Quality assessment was based on an evaluation scheme adjusted to study design and normalized to 100%. The cut-off for sufficient quality to include articles was above 40% and cut-off for high-quality articles was above 50% of maximal score. The level of strength of evidence for an association between exposure and effect was assessed according to the GRADE guidelines. RESULTS Thirty-four articles were included. Articles that document large effects (higher risk estimates; OR ≥ 2) have higher quality score, include analyses of severe arm elevation, more often use clinical outcome, and report an exposure-response relationship compared to studies reporting lower risk estimates. The studies that reported large effects were all significant. An exposure-response relationship was found in many high-quality studies when relating exposure intensity of arm elevation (level of arm elevation, amplitude) as well as duration of arm elevation, especially > 90°. CONCLUSION We conclude on a limited evidence for an association between arm elevation at work and shoulder disorders. Severe arm elevation with elbows above shoulder level (i.e., > 90°) shows a moderate evidence for an association with shoulder disorders.

Abstract
OBJECTIVES To identify credible anchor-based minimal important differences (MIDs) for patient-reported outcome measures (PROMs) relevant to a BMJ Rapid Recommendations addressing subacromial decompression surgery for shoulder pain. DESIGN Systematic review. OUTCOME MEASURES Estimates of anchor-based MIDs, and their credibility, for PROMs judged by the parallel BMJ Rapid Recommendations panel as important for informing their recommendation (pain, function and health-related quality of life (HRQoL)). DATA SOURCES MEDLINE, EMBASE and PsycINFO up to August 2018. STUDY SELECTION AND REVIEW METHODS We included original studies of any intervention for shoulder conditions reporting estimates of anchor-based MIDs for relevant PROMs. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria. Six reviewers, working in pairs, independently extracted data from eligible studies using a predesigned, standardised, pilot-tested extraction form and independently assessed the credibility of included studies using an MID credibility tool. RESULTS We identified 22 studies involving 5562 patients that reported 74 empirically estimated anchor-based MIDs for 10 candidate instruments to assess shoulder pain, function and HRQoL. We identified MIDs of high credibility for pain and function outcomes and of low credibility for HRQoL. We offered median estimates for the systematic review team who applied these MIDs in Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence summaries and in their interpretations of results in the linked systematic review addressing the effectiveness of surgery for shoulder pain. CONCLUSIONS Our review provides anchor-based MID estimates, as well as a rating of their credibility, for PROMs for patients with shoulder conditions. The MID estimates inform the interpretation for a linked systematic review and guideline addressing subacromial decompression surgery for shoulder pain, and could also prove useful for authors addressing other interventions for shoulder problems.

Abstract
OBJECTIVES To compare the prevalence of shoulder disorders and self-reported shoulder disability in patients with long-term type 1 diabetes mellitus and diabetes-free subjects; and to explore the association between the long-term glycemic burden and shoulder disability in the diabetes group. DESIGN Cross-sectional study of shoulder diagnoses with 30 years' historical data on glycemic burden in patients with diabetes. SETTING Diabetics center and a university hospital. PARTICIPANTS Subjects attending the Norwegian Diabetics Center in 2015 with type 1 diabetes since 1970 or earlier were eligible (N=136). One hundred and five patients were included, and 102 (50% women; mean age, 61.9y) completed the study together with 73 diabetes-free subjects (55% women; mean age, 62.5y). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Shoulder diagnoses decided through clinical examination according to scientific diagnostic criteria. RESULTS Frozen shoulder was diagnosed in 60 (59%) patients with diabetes and 0 diabetes-free subjects, with a lifetime prevalence of 76% in the diabetes group versus 14% in the diabetes-free subjects. Patients with diabetes had higher disability and higher mean QuickDASH scores (23.0±19.9) than diabetes-free subjects (8.9±12.0), with a mean difference of -14.2 (95% confidence interval, -19.3 to -9.0) points (P<.001). We found an association between chronic hyperglycemia and QuickDASH scores, with a 6.16-point increase in QuickDASH scores per unit increase in glycated hemoglobin A1c (HbA1c) (P=.014). CONCLUSIONS The point prevalence of frozen shoulder in patients with long-lasting type 1 diabetes was 59%, and the lifetime prevalence was 76%. The diabetes group had more shoulder disability than diabetes-free subjects. The historical HbA1c level was associated with increased shoulder disability.

Abstract
Complaints of the arms, neck, and shoulders (CANS) represent a major public health problem but the long-term course is largely unknown. Our objective was to explore the 15-year course of chronic CANS and its determinants in a population-based cohort. During 1993 to 2012, 3050 men and women aged 26 to 65 years at baseline were measured every 5 years, up to 4 times. Complaints of the arms, neck, and shoulders and sociodemographic, lifestyle, mental health, and physical load determinants were obtained by self-reported questionnaires and physical examinations. Information on chronic CANS was used to create patterns of the 15-year course: persistence, recovery, variable, no CANS, and the development of CANS. Only 47% were free of chronic CANS throughout the total 15-year period. The prevalence of other patterns was development (18.3%), persistence (8.5%), recovery (7.5%), and variable (18.7%). In multivariable logistic regression analyses, female gender, age 46 to 55 years, being not employed, former smoking, physical inactivity, an episode of CANS during the past 12 months, and high physical load in daily life (eg, often adopting awkward postures, frequent lifting, carrying, pushing, or pulling) were associated with the development of chronic CANS. Female gender, age 36 to 45 years, being not employed, and awkward postures in daily life were associated with persistent CANS. We conclude that chronic CANS represent a dynamic condition and affect the majority of the general population at least once in 15 years. Determinants associated with chronic CANS, especially physical load in daily life, can be used to develop preventive interventions and give guidance to treatment.

Abstract
Upper limb injuries are highly prevalent in the workplace and new tools are needed to proactively design workstations to reduce injury risk. The objective was to characterize spatial, load and direction dependency of muscle activity for hand exertions in the upper limb workspace. Electromyographic signals were collected from 14 upper limb muscles during exertions for all combinations of 4 submaximal hand forces (20/30/50/60 N) in 6 cardinal (up/down/left/right/forward/backward) directions at 5 hand locations. Linear muscle activity increases accompanied increased hand forces. Total muscle activity increases between 20 and 60 N hand forces ranged by direction from 92% (downward) to 189% (right). Prediction equations for all muscles depended on hand force, and linear, quadratic and interaction permutations of hand location. Muscle activity associated with manual tasks is load, direction and spatially dependent. Equations developed to describe these complex relationships can be used to better design future and evaluate current occupational activities.

Abstract
Background Although humeral epicondylitis is a common health problem, there have been no reports that describe its prevalence in Japanese general population, and relatively little is known about its etiology and associated risk factors. Questions/purposes This study aimed to clarify the prevalence of humeral epicondilitis in Japanese general population, and investigate the associated risk factors using the data from a cross-sectional study of the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS). Methods A total of 1,777 participants who participated in health checkups conducted at rural area in Japan in 2010 were enrolled. The prevalence of lateral and medial epicondylitis was investigated. Logistic regression models were performed to examine the relationship between lateral epicondylitis and correlated factors such as occupational status, smoking and alcohol preferences, and medical characteristics. Results The overall prevalence of lateral and medial epicondylitis was 2.5 % and 0.3 %, respectively. A shortened version of the disabilities of the arm, shoulder and hand (The QuickDASH) score was significantly higher in subjects with lateral epicondylitis than in those without (15.0 ± 12.7 vs 8.5 ± 11.1). Subjects with definite chronic hyperglycemia (HbA1c ≥ 6.5) showed a 3.37-times higher risk of lateral epicondylitis than those with favorable glycemic control (HbA1c < 5.5) (95 % confidence interval (CI) 1.16–8.56). Age and sex, as well as occupational status, smoking and alcohol preference, and other metabolic factors were not significantly related to higher risk of lateral epicondylitis. Conclusions Lateral epicondylitis influences activities of daily living. Chronic hyperglycemia might be one of the risk factor for lateral epicondylitis. Clinical relevance Chronic hyperglycemia is significantly associated with lateral epicondylitis.

Abstract
OBJECTIVE The objective of this retrospective study of non-inflammatory rheumatic disease patients was to investigate if the individuals clinically identified with muscular hypertonicity (MHT) had increased clinical manifestations compared with those of age- and gender-matched patients with the same disorders. MATERIAL AND METHODS The MHT status was clinically identified in the rheumatologist's myofascial protocol examination as relatively increased passive resistance of relaxed muscle on a slow gentle stretch. Clinical and laboratory data were abstracted on a pre-coded form, including symptom and physical examination features, serum assays, and medications. RESULTS The 19 MHT cases complained of greater subjective stiffness (p=0.010) and tiredness (p=0.018) at initial encounters and increased aching pain (p=0.049) and were prescribed more (p=0.003) mild narcotic analgesics than the 19 comparison patients. The cases had higher (p=0.027) serum creatine kinase levels, and patients with diffuse MHT had greater frequency of heavy (30+pack-years) cigarette smoking (p=0.002) than comparison subjects. Narcotic usage was also greater in cases with diffuse involvement. CONCLUSION Non-inflammatory rheumatic disease patients with MHT had an overall similar profile as that of comparison patients but had greater musculoskeletal complaints, and those with diffuse involvement had greater narcotic usage. Further research, including quantitative measurements of muscle stiffness, are required to determine whether MHT is a documented entity associated with increased rheumatological manifestations.

Abstract
Plantar fasciitis affects nearly 1 million persons in the United States at any one time. Conservative therapies have been reported to successfully treat 90% of plantar fasciitis cases; however, for the remaining cases, only invasive therapeutic solutions remain. This investigation studied newly emerging technology, low-level laser therapy. From September 2011 to June 2013, 69 subjects were enrolled in a placebo-controlled, randomized, double-blind, multicenter study that evaluated the clinical utility of low-level laser therapy for the treatment of unilateral chronic fasciitis. The volunteer participants were treated twice a week for 3 weeks for a total of 6 treatments and were evaluated at 5 separate time points: before the procedure and at weeks 1, 2, 3, 6, and 8. The pain rating was recorded using a visual analog scale, with 0 representing "no pain" and 100 representing "worst pain." Additionally, Doppler ultrasonography was performed on the plantar fascia to measure the fascial thickness before and after treatment. Study participants also completed the Foot Function Index. At the final follow-up visit, the group participants demonstrated a mean improvement in heel pain with a visual analog scale score of 29.6 ± 24.9 compared with the placebo subjects, who reported a mean improvement of 5.4 ± 16.0, a statistically significant difference (p < .001). Although additional studies are warranted, these data have demonstrated that low-level laser therapy is a promising treatment of plantar fasciitis.

Abstract
Introduction: The cervical syndrome refers to a set of disorders caused by the changes in the cervical spine and the soft-tissue surrounding it, with pain as the predominant symptom. Sore neck has been a common problem among a large section of today`s population. The factors contributing to this issue include the modern lifestyle, prolonged sitting and incorrect, fixed or constrained working postures. The root of these difficulties is found in the mechanical disorders of the cervical spine structures, poor body posture and jerky body movements. In the Scandinavian countries neck pain is considered to be a public health problem. Methods: The study evaluated 25 patients with an established diagnosis of cervical syndrome. The research was conducted at the PI Institute of Occupational and Sports Medicine of Zenica–Doboj Canton. Each patient received twenty physical therapy treatment sessions. Results and conclusions: The study included 25 patients suffering from the cervical syndrome. The statistical analysis of gender distribution indicated that 36% of the patients were male, while 64% were female. The mean age of study participants was 46.76±4,23. The patients ranged in age from 39 to 54 years, with no statistically significant difference in the mean age of male and female patients, p=0.691. Analysing the types of occupational activities performed by the patients, the study found a positive relation between neck pain and prolonged sitting at work. The patients who performed office work made up 76% of the total number. Each method of physical therapy applied in the treatment of neck pain patients proved useful. However, the combination of electrotherapy, kinesiotherapy and manual massage proved to be most effective. Conclusion: The cervical syndrome is a common medical condition primarily affecting adult population, with prevalence being higher among women and office workers. The condition places a considerable socioeconomic burden on the afflicted. Cervical pain ranges greatly in severity – from moderate to unbearable, thus leading to high levels of work absence as well as to a decrease in the quality of life. Proper physical therapy program can help the patients with neck pain return to their normal everyday activities, improve their quality of life, as well as reduce the absence from work.

Abstract
BACKGROUND Population studies have reported that shoulder pain is the third most frequently reported musculoskeletal pain. Long duration, pain intensity and high level of disability predict persistent complaints. The present study aimed to describe the prevalence of shoulder pain in a general population and follow this over a long period (1990 to 2004). The objective was also to describe the stability of shoulder pain and patterns of co-occurrence with neck and upper back pain. METHODS Data were obtained from a self-reported questionnaire in a population in Ullensaker muncipality, north-east of Oslo. The Standard Nordic Questionnaire was sent in 1990, 1994 and 2004 to inhabitants belonging to six birth cohorts from 1918-20 to 1968-70. RESULTS The 1-year prevalence of shoulder pain was 46.7% (95% CI, 44.9% to 48.6%) in 1990, 48.7% (95% CI, 46.8% to 50.5%) in 1994, and 55.2% (95% CI, 53.5% to 56.9%) in 2004. Approximately three-quarters of the persons with shoulder pain at one given time also reported shoulder pain at the next follow-up. CONCLUSIONS Prevalence of shoulder pain during a 14-year period was high and slightly increasing. Shoulder pain was reported most frequently in co-occurrence with neck pain. Classification models should include neck pain as well as other co-occurring pain sites.

Abstract
This study investigated the relation between working conditions, in terms of physical and psychological demand, and upper-limb and neck musculoskeletal disorders (ULNMD) in female staff working in direct contact with the elderly in nursing homes. A cross-sectional survey was conducted in 105 nursing homes in France. Data on nursing-home working conditions were collected by questionnaire from occupational physicians and by self-administered questionnaire from staff. Psychosocial demand at work was assessed on Siegrist's questionnaire and ULNMD on the Nordic questionnaire. 2,328 employees were included: 628 housekeepers, 1,372 nursing assistants and 328 nurses. During the previous 12 months, 50% of the subjects (1,160) had presented with a musculoskeletal complaint concerning the neck, 38% (881) the shoulders, 10% (246) the elbows and 22% (520) the wrists. 9% (219) reported effort/reward imbalance on the 2004 Siegrist questionnaire and 42% were in a situation of over-commitment. ULNMD complaints were associated not only with physical occupational factors but also with psychosocial factors (effort/reward imbalance and over-commitment), both before and after adjustment on individual and occupational factors. Prospective studies are needed to clarify the causal role of occupational, including, organizational, psychosocial factors in ULNMD outcomes. Preventive approaches should take account of both physical and psychosocial occupational factors.

Abstract
Anatabine is a Solanaceae plant family alkaloid marketed in the United States as a dietary supplement. It has demonstrated anti-inflammatory effects in vivo and in vitro, and may be useful for musculoskeletal aches and pains. The purpose of this internet-based survey study was to provide more information about anatabine users who report benefits for joint pain or stiffness. Of the 282 survey respondents, 232 (82%) reported a benefit from anatabine supplementation for one or more joint pain conditions, most commonly the knee, wrists/hands/fingers, shoulder, and back, most often due to osteoarthritis or injury to the joint. Mean scores of joint pain and stiffness were significantly (P < 0.0001) reduced after starting anatabine supplementation, and for most respondents joint pain was virtually eliminated. Around 90% of all individuals rated the effect of anatabine supplementation as good or excellent for joint pain, stiffness, functionality, and overall effects. These results provide evidence that anatabine supplementation can lead to substantial improvement of musculoskeletal aches, pains, and stiffness, and can provide benefits in some individuals for various medical conditions in multiple joint locations.

Abstract
BACKGROUND To explore whether risk factors for neurophysiologically confirmed carpal tunnel syndrome (CTS) differ from those for sensory symptoms with normal median nerve conduction, and to test the validity and practical utility of a proposed definition for impaired median nerve conduction, we carried out a case-control study of patients referred for investigation of suspected CTS. METHODS We compared 475 patients with neurophysiological abnormality (NP+ve) according to the definition, 409 patients investigated for CTS but classed as negative on neurophysiological testing (NP-ve), and 799 controls. Exposures to risk factors were ascertained by self-administered questionnaire. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated by logistic regression. RESULTS NP+ve disease was associated with obesity, use of vibratory tools, repetitive movement of the wrist or fingers, poor mental health and workplace psychosocial stressors. NP-ve illness was also related to poor mental health and occupational psychosocial stressors, but differed from NP+ve disease in showing associations also with prolonged use of computer keyboards and tendency to somatise, and no relation to obesity. In direct comparison of NP+ve and NP-ve patients (the latter being taken as the reference category), the most notable differences were for obesity (OR 2.7, 95 % CI 1.9-3.9), somatising tendency (OR 0.6, 95% CI 0.4-0.9), diabetes (OR 1.6, 95% CI 0.9-3.1) and work with vibratory tools (OR 1.4, 95% CI 0.9-2.2). CONCLUSIONS When viewed in the context of earlier research, our findings suggest that obesity, diabetes, use of hand-held vibratory tools, and repeated forceful movements of the wrist and hand are causes of impaired median nerve function. In addition, sensory symptoms in the hand, whether from identifiable pathology or non-specific in origin, may be rendered more prominent and distressing by hand activity, low mood, tendency to somatise, and psychosocial stressors at work. These differences in associations with risk factors support the validity of our definition of impaired median nerve conduction.

Abstract
BACKGROUND To systematically analyse evidence on the incremental effect of work-related psychosocial risk factors on the development of neck and shoulder disorders, as reported in longitudinal studies. METHODS A systematic literature search was conducted in three data bases (MEDLINE, EMBASE, and PsychINFO) until May 2009. The quality assessment leading to a methodological quality score of the included studies was conducted by two independent reviewers using a standardised checklist. Criteria for the evaluation of evidence were established. Heterogeneity analyses were conducted. RESULTS Altogether 18 prospective longitudinal studies were included in the analysis. Potential psychosocial risk factors were mainly based on the job demand control (support) model by Karasek (1998). Study results were too heterogeneous to deduce pooled risk estimates. But the weight of evidence was strong for an incremental effect of job demands, job control, social support, and job strain, on the development of neck and/or shoulder disorders. CONCLUSION While we found evidence for an incremental effect of different psychosocial work factors (in addition to the effect of physical job factors), these results have to be interpreted carefully in order to support the notion that psychological factors can have an independent causal influence on the development of musculoskeletal disorders. Nevertheless, our findings are important for the development of preventive strategies, as they stress the need for preventive approaches that tackle both physical and psychosocial factors. Future research is warranted to consolidate and strengthen the results of this review.

Abstract
AIM The aim of this study was to prospectively investigate the association between leisure time physical exercise, body mass index (BMI) and risk of chronic arm pain. METHODS The study population comprises 14,041 women and 13,674 men in the Norwegian HUNT Study without musculoskeletal pain or physical impairment at baseline in 1984-86. Chronic arm pain was assessed at follow-up in 1995-97. A generalized linear model was used to calculate adjusted relative risks (RRs). RESULTS At follow-up, 2205 women and 1458 men reported chronic arm pain. Level of physical exercise was inversely associated with risk of chronic arm pain (P-trend, ≤0.03 for both sexes). Compared with inactive persons, women and men who exercised ≥ 2 h/week had adjusted RRs of 0.84 [95% confidence interval (CI), 0.73-0.96] and 0.74 (95% CI, 0.63-0.87), respectively. BMI was positively associated with risk of chronic arm pain (P-trend, ≤0.002 for both sexes). Compared with normal-weight persons, women and men classified as obese (BMI ≥ 30 kg/m2) had adjusted RRs of 1.26 (95% CI, 1.11-1.44) and 1.29 (95% CI, 1.07-1.57), respectively. Combined analysis showed that obese women and men who exercised ≥ 1 h/week had a RR of 1.20 (95% CI 0.97-1.48) compared with normal-weight women and men with a similar activity level, whereas the RR was 1.41 (95% CI 1.21-1.65) for obese women and men who were physically inactive. CONCLUSION Regular physical exercise reduces risk of chronic arm pain while high BMI increases the risk. Exercise can to some extent compensate for the adverse effect of obesity on risk of chronic arm pain.

Referred pain from myofascial trigger points in head, neck, shoulder, and arm muscles reproduces pain symptoms in blue-collar (manual) and white-collar (office) workers. Clin J Pain 2012; 28:511-8.

Abstract
OBJECTIVE To describe the prevalence and referred pain area of trigger points (TrPs) in blue-collar (manual) and white-collar (office) workers, and to analyze if the referred pain pattern elicited from TrPs completely reproduces the overall spontaneous pain pattern. METHODS Sixteen (62% women) blue-collar and 19 (75% women) white-collar workers were included in this study. TrPs in the temporalis, masseter, upper trapezius, sternocleidomastoid, splenius capitis, oblique capitis inferior, levator scapulae, scalene, pectoralis major, deltoid, infraspinatus, extensor carpi radialis brevis and longus, extensor digitorum communis, and supinator muscles were examined bilaterally (hyper-sensible tender spot within a palpable taut band, local twitch response with snapping palpation, and elicited referred pain pattern with palpation) by experienced assessors blinded to the participants' condition. TrPs were considered active when the local and referred pain reproduced any symptom and the patient recognized the pain as familiar. The referred pain areas were drawn on anatomic maps, digitized, and measured. RESULTS Blue-collar workers had a mean of 6 (SD: 3) active and 10 (SD: 5) latent TrPs, whereas white-collar workers had a mean of 6 (SD: 4) active and 11 (SD: 6) latent TrPs (P>0.548). No significant differences in the distribution of active and latent TrPs in the analyzed muscles between groups were found. Active TrPs in the upper trapezius, infraspinatus, levator scapulae, and extensor carpi radialis brevis muscles were the most prevalent in both groups. Significant differences in referred pain areas between muscles (P<0.001) were found; pectoralis major, infraspinatus, upper trapezius, and scalene muscles showed the largest referred pain areas (P<0.01), whereas the temporalis, masseter, and splenius capitis muscles showed the smallest (P<0.05). The combination of the referred pain from TrPs reproduced the overall clinical pain area in all participants. CONCLUSIONS Blue-collar and white-collar workers exhibited a similar number of TrPs in the upper quadrant musculature. The referred pain elicited by active TrPs reproduced the overall pain pattern. The distribution of TrPs was not significantly different between groups. Clinicians should examine for the presence of muscle TrPs in blue-collar and white-collar workers.

Abstract
In recent years, increased knowledge of the pathogenesis of upper quadrant pain syndromes has translated to better management strategies. Recent studies have demonstrated evidence of peripheral and central sensitization mechanisms in different local pain syndromes of the upper quadrant such as idiopathic neck pain, lateral epicondylalgia, whiplash-associated disorders, shoulder impingement, and carpal tunnel syndrome. Therefore, a treatment-based classification approach where subjects receive matched interventions has been developed and, it has been found that these patients experience better outcomes than those receiving non-matched interventions. There is evidence suggesting that the cervical and thoracic spine is involved in upper quadrant pain. Spinal manipulation has been found to be effective for patients with elbow pain, neck pain, or cervicobrachial pain. Additionally, it is known that spinal manipulative therapy exerts neurophysiological effects that can activate pain modulation mechanisms. This paper exposes some manual therapies for upper quadrant pain syndromes, based on a nociceptive pain rationale for modulating central nervous system including trigger point therapy, dry needling, mobilization or manipulation, and cognitive pain approaches.

Abstract
BACKGROUND Hand problems are common in older adults and cause significant pain and disruption to everyday living. The aim of this systematic review was to summarize evidence on the factors associated with the severity and progression of self-reported hand pain and functional difficulty in population-based studies of older adults. METHODS MEDLINE, EMBASE, CINAL, BNI, AMED, HMIC, PsycINFO and ISI Web of Knowledge were searched up to January 2011 for relevant articles. The search strategy combined text words for hand, pain, function and epidemiological study. Inclusion criteria were applied and articles in the review assessed for quality using the QUality In Prognosis Studies (QUIPS) assessment tool. Data extraction included: author, year of publication, study location, participant inclusion criteria, risk factor and outcome measurement, and association with hand pain and/or function. RESULTS Seven articles from five studies met the inclusion criteria from 5,679 citations. All studies were cross-sectional and provided no information on progression of hand pain and function over time. Factors associated with limited hand function were older age, female gender, manual occupation, neck or shoulder pain, clinical and radiographic osteoarthritis, weaker hand strength, hand pain, history of Parkinson's disease, stroke, diabetes or rheumatoid arthritis, and illness perceptions (namely, frustration, impact and symptom count). Key factors associated with hand pain severity were age, impact, frustration, patient expectation of a long disease time course and self-reported diagnosis of the cause of the hand problem. CONCLUSIONS Both demographic and clinical factors were found to be related to self-reported hand pain severity and functional difficulty in older adults; however, the results were derived from a small number of studies, with no information on progression of hand pain and functional difficulty over time.

Abstract
OBJECTIVE To explore the relationship between occupational exposures and lateral and medial epicondylitis, and the effect of epicondylitis on sickness absence in a population sample of working-aged adults. METHODS This was a cross-sectional study of 9696 randomly selected adults aged 25-64 years involving a screening questionnaire and standardized physical examination. Age- and sex-specific prevalence rates of epicondylitis were estimated and associations with occupational risk factors explored. RESULTS Among 6038 respondents, 636 (11%) reported elbow pain in the last week. Of those surveyed, 0.7% were diagnosed with lateral epicondylitis and 0.6% with medial epicondylitis. Lateral epicondylitis was associated with manual work [odds ratio (OR) 4.0, 95% CI 1.9, 8.4]. In multivariate analyses, repetitive bending/straightening elbow >1 h day was independently associated with lateral (OR 2.5, 95% CI 1.2, 5.5) and medial epicondylitis (OR 5.1, 95% CI 1.8, 14.3). Five per cent of adults with epicondylitis took sickness absence because of their elbow symptoms in the past 12 months (median 29 days). CONCLUSION Repetitive exposure to bending/straightening the elbow was a significant risk factor for medial and lateral epicondylitis. Epicondylitis is associated with prolonged sickness absence in 5% of affected working-aged adults.

Abstract
Obesity within today's workforce is increasingly recognized as a challenge for both public health professionals and ergonomists. The two disciplines share a scientific, evidence-based approach to practice and now have the opportunity to address a common health issue, namely obesity. This paper shows, through an overview of the current literature, how and where obesity is impacting on the workplace and how the health of the workforce is being affected. Ergonomics and public health priorities have been mapped and challenges suitable for the application of existing knowledge and further research have been identified. Areas of common endeavour, for example how sedentary work may be exacerbating obesity, have been identified as candidate topics for joint activity by ergonomists and public health professionals.

Abstract
UNLABELLED Fibromyalgia syndrome (FMS) is a prevalent and disabling chronic pain disorder. Past research suggests that obesity is a common comorbidity and may be related to the severity of FMS. The main objective of the present study was to evaluate the relationships between FMS and obesity in the multiple FMS-related domains: hyperalgesia, symptoms, physical abilities, and sleep. A total of 215 FMS patients completed a set of self-report inventories to assess FMS-related symptoms and underwent the tender point (TP) examination, physical performance testing, and 7-day home sleep assessment. Forty-seven percent of our sample was obese and an additional 30% was overweight. Obesity was related significantly to greater pain sensitivity to TP palpation particularly in the lower body areas, reduced physical strength and lower-body flexibility, shorter sleep duration, and greater restlessness during sleep. The results confirmed that obesity is a prevalent comorbidity of FMS that may contribute to the severity of the problem. Potential mechanisms underlying the relationship are discussed. PERSPECTIVE This report presents how obesity may be interrelated to fibromyalgia pain, disability, and sleep. We found that obesity is common in FMS. Approximately half of our patients were obese and an additional 30% were overweight. We also found that obesity in FMS was associated with greater pain sensitivity, poorer sleep quality, and reduced physical strength and flexibility. The results suggest that obesity may aggregate FMS and weight management may need to be incorporated into treatments.

Abstract
STUDY DESIGN Case-control study with blinded examiner. OBJECTIVE To investigate if pressure pain sensitivity is related to specific nerve trunks in the upper extremity of patients with either unilateral lateral epicondylalgia (LE) or carpal tunnel syndrome (CTS). BACKGROUND In the clinical setting, patients with LE tend to exhibit radial nerve trunk tenderness, whereas patients with CTS exhibit median nerve tenderness. No studies have investigated if specific nerve pressure pain hypersensitivity exists in patients with either LE or CTS. METHODS Sixteen women with unilateral LE (mean±SD age, 43±7 years), 17 women with unilateral CTS (43±6 years), and 17 healthy women (43±6 years) were included in this study. Pressure pain thresholds (PPT) were bilaterally assessed over the median, ulnar, and radial nerve trunks, as well as over the C5-6 zygapophyseal joints, by an examiner blinded to the subjectsí condition. A mixed-model analysis of variance was used to evaluate differences in PPT among groups (LE, CTS, or controls) and between sides (affected/nonaffected or dominant/nondominant). RESULTS The individuals in both the LE and CTS groups demonstrated lower PPT bilaterally over the median (group, P<.001; side, P=.437), radial (group, P<.001; side, P=.556), and ulnar (group, P<.001; side, P=.938) nerve trunks as compared to controls. Additionally, radial (P<.001) and ulnar (P=.005) nerves were more sensitive bilaterally in patients with LE than in patients with CTS. The median nerve was more sensitive bilaterally in patients with CTS than patients with LE (P=.002). Lower PPT over the cervical spine (group, P<.001; side, P=.233) were found bilaterally in both the LE and CTS groups. Further, patients with CTS exhibited lower cervical PPT than patients with LE (P<.001). PPT was negatively correlated with both pain intensity and duration of symptoms in both the LE and CTS groups (P<.001). CONCLUSIONS Bilateral mechanical nerve pain hypersensitivity is related to specific and particular nerve trunks in women with either unilateral LE or CTS. Our results suggest the presence of central and peripheral sensitization mechanisms in individuals with either LE or CTS.

Abstract
OBJECTIVE To assess the relative importance of personal and occupational risk factors for upper-extremity musculoskeletal disorders in the working population. METHODS A total of 3,710 workers (58% men) participating in a surveillance program of musculoskeletal disorders in a French region in 2002-2005 were included. Upper-extremity musculoskeletal disorders were diagnosed by 83 trained occupational physicians performing a standardized physical examination. Personal factors and work exposure were assessed by a self-administered questionnaire. Statistical associations between musculoskeletal disorders, personal, and occupational factors were analyzed using logistic regression modeling. RESULTS A total of 472 workers experienced at least 1 upper-extremity musculoskeletal disorder. The risk of upper-extremity musculoskeletal disorders increased with age for both sexes (P < 0.001, odds ratio [OR] < or =4.9 in men and < or =5.0 in women), and in cases of prior history of upper-extremity musculoskeletal disorders (OR 3.1 and 5.0, respectively, P < 0.001). In men, upper-extremity musculoskeletal disorders were associated with obesity (OR 2.2, P = 0.014), high level of physical demand (OR 2.0, P < 0.001), high repetitiveness of the task (OR 1.5, P = 0.027), postures with the arms at or above shoulder level (OR 1.7, P = 0.009) or with full elbow flexion (OR 1.6, P = 0.006), and high psychological demand (OR 1.5, P = 0.005). In women, upper-extremity musculoskeletal disorders were associated with diabetes mellitus (OR 4.9, P = 0.001), postures with extreme wrist bending (OR 2.0, P < 0.001), use of vibrating hand tools (OR 2.2, P = 0.025), and low level of decision authority (OR 1.4, P = 0.042). CONCLUSION Personal and work-related physical and psychosocial factors were strongly associated with clinically diagnosed upper-extremity musculoskeletal disorders.

Abstract
OBJECTIVES To establish whether review articles provide consistent conclusions on associations between workplace psychosocial factors and musculoskeletal pain and, if differences exist, to explore whether this is related to the methods used. METHODS Reviews, reported up to February 2007, that included consideration of workplace psychosocial factors and upper limb, back or knee pain were identified through searches of multiple databases. The specific work-related psychosocial factors considered were job demands, support, job autonomy and job satisfaction. The conclusions of each review on one or more of the psychosocial/musculoskeletal pain associations were extracted. RESULTS 15 review articles were identified that considered one or more of the regional pain syndromes included in the study. For back pain, the most consistent conclusions (four reviews positive out of six) were with high job demands and low job satisfaction. The studies of upper limb pain were exclusively related to shoulder and/or neck pain, and the most consistent positive conclusions were with high and low job demands (four reviews positive out of six and two reviews positive out of three, respectively). For knee pain, only a single review was identified. For individual reviews of back and upper limb pain, there were marked differences in the number of associations concluded to be positive between reviews. CONCLUSIONS The reasons for reviews coming to different conclusions included that they were often evaluating different bodies of evidence (according to their search criteria, the year when the review was conducted, the role that quality assessment played in whether studies contributed to evidence, and the combination of risk factors addressed in individual studies), but more important was whether the review specified explicit criteria for making conclusions on strength of evidence. These conclusions emphasise the importance of developing standardised methods for conducting such evaluations of existing evidence and the importance of new longitudinal studies for clarifying the temporal relationship between psychosocial factors and musculoskeletal pain in the workplace.

Abstract
Dentists reported high perceived physical work conditions. Working postures and movements of the head and upper extremities during dental work were registered with inclinometry measurements during four hours. The aim was to clarify the relationship between measured working postures/movements and perceived physical work conditions. Dentists worked with elevated arms and a rather steep forward inclination of the head. Correlations (r=-0.52 to -0.66) between inclination velocity and perceived workload on VAS scales were found, but there were only weak correlations between observed working postures. The different tasks involved in dental work provide limited variation in work movements and postures, measured by inclinometry. By alternating between sitting and standing, it might be possible to achieve variation in physical workload during dental work.

Abstract
Head and neck posture is an important factor in neck pain related to computer use; however, the evidence for an optimal posture is unconvincing. This study measured the 3-D postures of 36 young adults during use of three different display heights. Cervical extensor muscle strain was estimated using modelled gravitational load moments and muscle capacities. The influence of more or less upper vs. lower cervical movement was also explored across a broad range of potential postures. Overall cervical extensor muscle capacity diminished away from a neutral posture whilst gravity moment increased with flexion. Overall cervical extensor muscle strain increased with head flexion but remained stable into head extension. Individual differences in the amount of upper and lower cervical movement had an important effect on strain, particularly for some muscles. Computer display height guidelines are an important component of ergonomics practice, yet the relative strain on neck extensor muscles as a function of display height has not been examined. The current findings provide more detailed biomechanical evidence that ergonomists can incorporate with usability and other evidence to determine appropriate display height recommendations.

BACKGROUND Upper limb disorders (ULDs) are clinically challenging and responsible for considerable work loss. There is a need to determine effective approaches for their management. AIM To determine evidence-based management strategies for work-relevant ULDs and explore whether a biopsychosocial approach is appropriate. METHODS Literature review using a best evidence synthesis. Data from articles identified through systematic searching of electronic databases and citation tracking were extracted into evidence tables. The information was synthesized into high-level evidence statements, which were ordered into themes covering classification/diagnosis, epidemiology, associations/risks and management/treatment, focusing on return to work or work retention and taking account of distinctions between non-specific complaints and specific diagnoses. RESULTS Neither biomedical treatment nor ergonomic workplace interventions alone offer an optimal solution; rather, multimodal interventions show considerable promise, particularly for occupational outcomes. Early return to work, or work retention, is an important goal for most cases and may be facilitated, where necessary, by transitional work arrangements. The emergent evidence indicates that successful management strategies require all the players to be on side and acting in a coordinated fashion; this requires engaging employers and workers to participate. CONCLUSIONS The biopsychosocial model applies: biological considerations should not be ignored, but psychosocial factors are more influential for occupational outcomes. Implementation of interventions that address the full range of psychosocial issues will require a cultural shift in the way the relationship between upper limb complaints and work is conceived and handled. Dissemination of evidence-based messages can contribute to the needed cultural shift.

BMC Musculoskelet Disord 2008; 9:127. [PMID: 18816371 PMCID: PMC2565675 DOI: 10.1186/1471-2474-9-127] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2008] [Accepted: 09/24/2008] [Indexed: 12/02/2022] Open
Abstract
Background Different research techniques indicate alterations in muscle tissue and in neuromuscular control of aching muscles in patients with chronic localized pain. Ultrasound can be used for analysis of muscle tissue dynamics in clinical practice. Aim This study introduces a new muscle tissue sensitive ultrasound technique in order to provide a new methodology for providing a description of local muscle changes. This method is applied to investigate trapezius muscle tissue response – especially with respect to specific regional deformation and deformation rates – during concentric shoulder elevation in patients with chronic trapezius myalgia and healthy controls before and after pain provocation. Methods Patients with trapezius myalgia and healthy controls were analyzed using an ultrasound system equipped with tissue velocity imaging (TVI). The patients performed a standardized 3-cm concentric shoulder elevation before and after pain provocation/exercise at a standardized elevation tempo (30 bpm). A standardized region of interest (ROI), an ellipsis with a size that captures the upper and lower fascia of the trapezius muscle (4 cm width) at rest, was placed in the first frame of the loop registration of the elevation. The ROI was re-anchored frame by frame following the same anatomical landmark in the basal fascia during all frames of the concentric phase. In cardiac measurement, tissue velocities are measured in the axial projection towards and against the probe where red colour represents shortening and red lengthening. In the case of measuring the trapezius muscle, tissue deformation measurements are made orthogonally, thus, indirectly. Based on the assumption of muscle volume incompressibility, blue represents tissue contraction and red relaxation. Within the ROI, two variables were calculated as a function of time: deformation and deformation rate. Hereafter, max, mean, and quadratic mean values (RMS) of each variable were calculated and compared before and after pain provocation/exercise. Results This new methodology seems valuable when looking at local muscle changes and studying the mechanism behind chronic muscle pain. The univariate analyses indicate that patients with chronic trapezius myalgia after pain provocation due to exercise at group level showed decreased strain and unchanged strain rate while healthy controls had unchanged strain and increased strain rate. However, the multivariate analysis indicates that most patients showed lower levels according to both strain and strain rate after exercise compared to most controls. Conclusion Tissue velocity imaging can help describe musculoskeletal tissue activity and dynamics in patients with chronic pain conditions. An altered muscle tissue dynamic after pain provocation/exercise among the majority of trapezius myalgia patients compared with the healthy controls was found.

Gender-specific adaptations of upper trapezius muscle activity to acute nociceptive stimulation. Pain 2008; 138:217-225. [PMID: 18485595 DOI: 10.1016/j.pain.2008.04.004] [Citation(s) in RCA: 55] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2007] [Revised: 04/01/2008] [Accepted: 04/07/2008] [Indexed: 11/20/2022]
Abstract
This study examined gender differences in the effect of experimental muscle pain on changes in the relative activation of regions of the upper trapezius muscle during a sustained contraction. Surface electromyographic (EMG) signals were recorded from multiple locations over the upper trapezius muscle with a 10 x 5 grid of electrodes from nine women and nine men during 90 degrees shoulder abduction sustained for 60s. Measurements were performed before and after the injection of 0.4 ml hypertonic (painful) and isotonic (control) saline into the cranial region of the upper trapezius muscle. The EMG root mean square (RMS) was computed for each location of the grid to form a map of the EMG amplitude distribution. The peak pain intensity following the injection of hypertonic saline was greater for women (numerical rating scale 0-10: women 6.0+/-2.1, men 4.2+/-0.9; P<0.01). For both genders, upper trapezius RMS averaged across the grid decreased following the injection of hypertonic saline (P<0.0001). Moreover, there was a relatively larger pain-induced decrease in RMS in the cranial region compared to the caudal region of the muscle for both genders. During the non-painful sustained contractions, the EMG RMS progressively increased more in the cranial than the caudal region, for both men and women, due to fatigue. This mechanism was maintained in men but not in women during the painful condition. The results demonstrate that muscle pain alters the normal adaptation of upper trapezius muscle activity to fatigue in women but not in men.

Abstract
OBJECTIVES A study of whether occupational physical load predicted subsequent chronic shoulder disorders. METHODS A comprehensive national survey was carried out among a representative sample (n = 7217) of the Finnish adult population in 1977-80. Twenty years later, 1286 participants from the previous survey were invited to be re-examined, and 909 (71%) participated. After excluding those with diagnosed shoulder disorders at baseline, 883 subjects were available for the analyses. RESULTS At follow-up, a physician diagnosed chronic shoulder disorders in 63 subjects (7%) using a standardised protocol. Work exposure to repetitive movements and vibration at baseline increased the risk of shoulder disorder: adjusted ORs 2.3 (95% CI 1.3 to 4.1) and 2.5 (1.2 to 5.2), respectively. Exposure to several physical factors increased the risk further, the adjusted OR was nearly 4 for at least three exposures. The adverse effects of physical work were seen even among those older than 75 years at follow-up. The statistically significant risk factors differed between genders: for men vibration and repetitive movements, and for women lifting heavy loads and working in awkward postures. Age and body mass index modified the effects of the physical exposures. The results remained similar after excluding those with any shoulder pain at baseline. CONCLUSIONS This is the first prospective study in a general population showing that occupational physical loading increases the risk of a subsequent clinical shoulder disorder and the effects seem to be long-term. Early preventive measures at the workplace may have long-lasting health benefits for the shoulder.

Musculoskeletal symptoms among young male workers and associations with exposure to hand-arm vibration and ergonomic stressors. Int Arch Occup Environ Health 2007; 81:595-602. [PMID: 17924132 DOI: 10.1007/s00420-007-0250-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2007] [Accepted: 09/05/2007] [Indexed: 10/22/2022]
Abstract
OBJECTIVE The overall aim of this study was to explore the association between incident musculoskeletal symptoms in the neck and upper limbs and exposure to hand-arm vibration and ergonomic stressors. METHODS The study has a prospective design and data at baseline and follow-up was assessed by self-administered questionnaires. The study population consisted of students that had graduated from vocational high schools in 2001-2003 in northern and western Sweden and a total of 586 men responded to both the baseline and follow-up questionnaires. The mean age was 20.7 (range 19-27) years, and the exposure information included questions regarding hand-arm vibration, postural stress, computer work, mental stress and perception of muscular tension. Musculoskeletal symptoms in the neck and upper limbs were assessed at baseline and at follow-up. RESULTS Men who reported their daily vibration exposure duration (work and leisure) as more than 1 h at baseline had an increased risk of neck pain in the preceding 7 days at follow-up, when adjusting for all the other exposure variables (PR 3.29, 95% CI 1.02-14.9). Men with a calculated 8-h weighted vibration exposure level [A(8)] above 1.7 m/s(2) had an increased risk of developing neck pain in both the unadjusted and adjusted analyses compared to those with an exposure level below 0.5 m/s(2). CONCLUSION Men who reported their daily vibration exposure duration (work and leisure) to be more than 1 h at baseline had an increased risk of neck pain for the preceding 7 days at follow-up. An increased prevalence of neck pain was also observed in individuals with a calculated 8-h frequency weighted vibration exposure level above 1.7 m/s(2) (calculated from data assessed at follow-up) compared to those with an exposure level below 0.5 m/s(2). The increased risks remained when adjusting for postural and mental stress; however the results could still be confounded by other ergonomic and physical load factors not adjusted for in the analyses.

Abstract
BACKGROUND Shoulder pain is prevalent and a common cause of disability at work and daily activities. Some studies suggest an association between risk factors of atherosclerosis and shoulder pain and disorders. AIM To assess associations between risk factors of atherosclerosis and shoulder pain or disorders and to discuss possible pathophysiological pathways for found associations. METHODS A systematic review was conducted searching Medline until June 2006. Two authors extracted data and assessed quality independently using the Cochrane criteria for the assessment of quality in non-experimental studies with slight modifications. Due to heterogeneity of studies, meta-analysis was not possible. Results were summarized and discussed paying attention to study design and quality. RESULTS Fifteen papers from 14 studies were included in the review. Diabetes was consistently associated with clinically defined shoulder disorders in population studies. Overweight or obesity was associated with the incidence of shoulder symptoms in three studies and with clinically defined shoulder disorders in one case control study. A few studies showed a preventive effect of physical exercise. Associations between smoking and shoulder disorders were seen only in studies on occupational populations. CONCLUSIONS A consistent association between diabetes and shoulder disorders, some associations for weight-related factors as well as a possible preventive effect from physical exercise and sports suggest a metabolic pathophysiological process in shoulder disorders. More prospective studies using appropriate analytical methods are needed.
