BackgroundSuprascapular nerve (SSN) block is a useful tool for pain control of different chronic shoulder pain syndromes. If the short‐term effect of nerve block using local anesthetics is not sufficient, pulsed radiofrequency (PRF) neuromodulation of the SSN may provide long‐term pain relief.Aim of InvestigationThe aim of this study was to determine the effectiveness of ultrasonography‐guided PRF of the SSN for management of chronic shoulder pain.Subjects and MethodThirty patients with chronic shoulder pain underwent diagnostic ultrasonography‐guided SSN block. After confirmation of positive results (>50% pain relief) via diagnostic testing, PRF of the SSN was performed in 27 patients, followed by application of dexamethasone; however, 2 patients had negative results with diagnostic block and 1 patient dropped out after positive results with diagnostic block. Pain was recorded using the VAS, and active range of motion of the affected shoulder was measured by goniometry (flexion, extension, adduction, abduction, external rotation, internal rotation). Assessments were done on day 0 and after 4, 8, 12, and 24 weeks.Statistical TestOne‐way analysis of variance testing.ResultsThe VAS score decreased significantly (P < 0.05) immediately after injection, and pain reduction was sustained for up to 24 weeks. Active range of motion in all directions also increased significantly (P < 0.5) after the procedure.ConclusionPRF of the SSN under ultrasonography guidance is a safe and effective treatment modality for management of chronic shoulder pain. The effect of a combination of PRF and a short‐acting corticosteroid lasts up to 24 weeks, thereby assisting patients in undergoing relatively painless physiotherapy.

Introduction. WHO recognizes low back pain as one of the most important ergonomic stressors. Therefore, the present study was designed to find out the magnitude of the problem among jute mill workers in India and identify possible associations. Methodology. This cross-sectional workplace based study was conducted among eight (8) selected jute mills of India. Subjects with self-reported back pain for at least last 12 weeks were included and n = 717 male jute mill workers actively engaged in work entered the study and completed all assessments. Results. Among all participants 55% (n = 392) had current chronic low back pain. Age was an important association with subjects in the age group of 40–59 years more likely to have pain (p = 0.02, OR 1.44). Regarding ergonomic risk factors lifting of load of more than 20 kg (p = 0.04, OR 1.42) and repetitive movements of limbs (p = 0.03, OR 0.67) were significant associations of chronic low back pain. Conclusion. This study identified a significant prevalence of current chronic low back pain among jute mill workers. Regarding ergonomic risk factors the present study has identified two significant associations: lifting of load above 20 kg and repetitive movements of limbs. Therefore, this study has identified need for workplace interventions in this occupational group employing approximately 3,50,000 workers in India.

IntroductionMusculoskeletal disorders (MSDs) are reported maximum among jute mill workers of India. The present study is designed to find out the actual magnitude of the problems among jute mill workers and to identify the possible associations between discomforts and working postures of these workers.MethodologyThis study was conducted among eight selected jute mills of India. 717 male jute mill workers actively engaged in work at least for one year were randomly selected in this study. Subjects with self-reported MSD complaints for at least last 12 weeks were included. A detailed posture analysis was performed among them by Ovako Working Posture Assessment System (OWAS) method.ResultsAmong all participants 55% had complained Chronic Low Back Pain (CLBP). Age had an important association with CLBP. Subjects in the age group of 40–59 years were more likely to have pain (p=0.02). Regarding ergonomic risk factors, lifting of load of more than 20 kg (p=0.04) and repetitive movements of limbs (p=0.03) had significant associations with CLBP.DiscussionPresent study identifies a significant prevalence of CLBP among jute mill workers. Regarding ergonomic risk factors, the study has identified that MSD is significantly associated with work related awkward postures, lifting of load above 20 kg, repetitive movements of limbs and prolonged standing during work. Jute mill workers are exposed to heavy workload with repetitive and forceful motions, which generally adopt awkward and uncomfortable postures and carrying of excessive loads that ultimately has got a great impact on their health. Therefore, this study suggests the urgent need for work place interventions for improvement of work related health of 3,50,000 Jute workers of India.
