Due to inherent portability of laptops, users frequently assume inconvenient postures while using them that may lead to discomfort or injury. The study was conducted to evaluate the postures and identify the prevalence of musculoskeletal symptoms in girls using laptops for which 100 college going female students between 18 - 25 years age group were selected through random sampling technique. A self-structured questionnaire was used to assess the laptop usage among adolescents and Rapid Upper Limb Assessment (RULA) was used to assess the posture of students while working with laptop. Standardized Nordic Musculoskeletal Questionnaire (SMSQ) was used to assess the nature and severity of self-rated musculoskeletal symptoms. Results revealed that the maximum respondent’s (74%) posture came under Action level 3 and 26% respondents comes under Action level 2 which indicated that the posture needed “further investigation and may need change” or “changes needed soon”. There was a positive correlation in Normal (0.50), Mild (0.31), Moderate (0.56) and Severe users (0.60) between the posture adopted by the respondents and the incidence of pain in last 12 months and in Normal (0.76), Mild (0.52), Moderate (0.56) and Severe user (0.65) respectively in last 7 days. The Musculoskeletal Symptoms was prominent in various anatomic regions like Neck, Shoulders, Upper back and Lower back, respectively. These symptoms if not addressed at an earlier stage might lead to Musculoskeletal Disorders.

Musculoskeletal disorders (MSDs) can be characterized from their occupational etiology and their occurrence; their chronicity generates negative repercussions for the health of workers, especially of artisanal fishing. To investigate the prevalence of generalized musculoskeletal disorders by body region and self-reported pain in a fishing population of northeastern Brazil, an epidemiological cross-sectional study was carried out in Santiago do Iguape, Bahia-Brazil, in 2017. The Brazilian version of the Nordic Musculoskeletal Questionnaire (NMQ), in addition to a questionnaire containing the socio-demographic and labor conditions were applied to a random stratified sample of 248 artisanal fisheries. There were 170 female shellfish gatherers and 78 fishermen, with a mean age of 36.7 years (SD = 10.5 years) and 43.3 years (SD = 11.8 years), respectively. The beginning of the labor activity was initiated at approximately 11 years of age. The average weekly income varied from 17.64 USD to 29.10 USD. The prevalence of MSD independent of occupation occurred in at least one body region in 93.5% and the presence of musculoskeletal pain/discomfort over the last seven days in 95.2% of the fishing workers. The highest prevalence of MSD was found in shellfish gatherers in: lower back (86.4%), wrist and hand (73.5%), and upper back (66.8%). In relation to the presence of pain in the last year, the frequency of pain was greater in the fishermen compared to the shellfish gatherers. The generalized severity of the MSD in 93.5% of this community of fishermen is evident, with emphasis in the following regions: lower back, wrist and hand and upper back in both groups, with occurrence of pain in more than one body region at the same time.
