Background: Musculoskeletal disorders are not only becoming prevalent among health care professionals in our country but are affecting their health and performance adversely. They are caused by poor ergonomics and awkward posture during work activities. The purpose of this study was to determine the frequency of neck and upper limb musculoskeletal disorders in dentists of Lahore, Pakistan. Material and Methods: This cross-sectional study was conducted during October 2017 to March 2018. The data was collected using convenient sampling technique from 162 Dentists including 52 males and 110 females of Children hospital Lahore, Punjab Dental hospital and Fatima Memorial Hospital, Lahore. Data was collected by using Mangalore Questionnaire for identification of musculoskeletal disorders. Descriptive analysis of the data was done using SPSS version 22.0. Results: Of 162 dentists, 115 (71%) suffered from musculoskeletal disorders. Shoulder was the most commonly affected region (30.9%) followed by neck (25.9%), arm (6.2%), wrist (4.3%), elbow (3.1%) and forearm (0.6%). Pain (45.7%) was found to be the most common complaint followed by muscle weakness (20.4%), paraesthesia (3.7%) and swelling (1.2%). Conclusions: It was concluded that majority of the dentists were suffering from musculoskeletal disorders with shoulder as the most affected region and pain as the most frequent complaint. Key words: Dentists, Musculoskeletal disorders, Neck pain, Upper extremity

Numerous investigators have performed cross-sectional studies of upper extremity musculoskeletal disorders (UEMSDs) among industrial workers, and modeled the prevalence of these conditions in relation to potential ergonomic exposures and other covariates. However, prospective studies have been rare for a variety of reasons. Results of a cross-sectional study of UEMSDs based on data collected approximately 5 years ago were published in 1999 (Latko et al., 1999). A subset of the workers from this study were available for re-examination approximately 5 years after the first investigation. The survey tools and clinical examination protocols used in the follow-up examinations were largely identical to the baseline procedures, thus permitting direct comparison of results between rounds. Workers from 2 of the 3 employers in the original study were available for the follow-up investigation. Just over 50% of available and eligible workers participated in the follow-up examinations (152 out of 267, or 57%). The mean age at follow-up was almost 48 years (standard deviation = 9.5 years). The mean body mass index (BMI) was 28.9 at follow-up, and just over half of the study participants were male (53%). Most subjects were still employed by the same employer, and most were still in the same jobs. The prevalence and severity of upper extremity symptoms declined significantly in most body regions between baseline and follow-up. In contrast, the prevalence of most upper extremity diagnoses (tendinitis and carpal tunnel syndrome based on symptoms, standardized physical examinations, and/or nerve conduction tests) increased slightly, though not significantly. Relative median-minus-ulnar peak latency differences increased slightly, and significantly, between rounds. There are almost no studies for comparison of results. More prospective studies are needed to better understand the natural history of upper extremity musculoskeletal disorders among workers.

BACKGROUND: Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions. OBJECTIVES: This study aims to implement a new ergonomics aid for the betterment of job procedures and improvement of productivity, health, and safety of the preadolescent farmers. METHODS: 100 male and 100 female preadolescent farmers were randomly selected from the villages of Tarakeswar, West Bengal, India, to evaluate and reduce work-related musculoskeletal disorders, physiological stress. Modified Nordic questionnaires, Body Part Discomfort (BPD) scale, and handgrip strength were assessed before and after using the ergonomics aid. RESULTS: The results of the study show that there was a significant change (decrease) in discomfort in the lower back, wrists, shoulder, and hands among preadolescent farmers when using the newly designed ergonomic aid. Handgrip strength increased and physiological stress was decreased among preadolescent farmers in post-intervention than pre-intervention in just after work conditions. Productivity has been increased in farming by decreasing absenteeism from work with the use of ergonomic aid. CONCLUSION: This study concludes that productivity has been increased in farming by decreasing absenteeism from work as well as by using the ergonomic aid the discomfort feeling has been decreased markedly.

To play a musical instrument, such as the violin or flute, requires controlled, adequate movements performed by the arm, hand, and fingers in an asymmetric playing posture. The movements are monotonous and often of long duration, involving static and repetitive muscle work of the upper extremity and neck-shoulder muscles. This situation may lead to an increased risk of contracting musculoskeletal problems. The aim of this cross-sectional study was to investigate the relationship between physical workload, defined as playing posture and playing time per week, and musculoskeletal disorders in music teachers. A questionnaire was distributed, with items based on work-related musculoskeletal disorders and physical working conditions. The study population consisted of music teachers employed at a Swedish municipal music school. Out of 61 music teachers, 47 (77%) agreed to participate, including 28 women and 19 men. The study group was divided into two groups depending on if they had an asymmetric or symmetric upper extremity/back playing position. Of the total participants, 77% reported musculoskeletal disorders during the preceding 12 months. Female teachers reported significantly more symptoms in the neck, shoulders, and upper back than male teachers. Music teachers with an asymmetric playing posture had significantly more musculoskeletal disorders than music teachers with a symmetric playing posture. This study demonstrates that an asymmetric playing position may affect the amount of musculoskeletal disorders in the upper extremity and back.
