“…The interaction of the long-term standing position and the activity pipetting was also associated with WMSP in present study. which is consistent to the past study conducted by Park J-K et al, in 2013 which shows that, the extensive use of pipettes been suspected to cause upper-limb disorders [20].…”

Objective: To find out the frequency of musculoskeletal pain and to identify risk factors among biomedical science students working in laboratory Methods: This cross-sectional study used Nordic musculoskeletal questionnaire among biomedical science students and was conducted in the university of Central Punjab and University of Lahore, Pakistan. Study sample comprised of 103 participants. Data was collected by using non-probability convenient sampling technique and was analyzed through SPPS v 21.0 Results: Out of 103 students reported a laboratory related musculoskeletal pain in the last 12 months while 16 (15.5%) within 7 days. The lower back (21.4% and 16.5%), neck (13.6% and 9.7%) and shoulders (10.7% and 6.8%) were the most common sites of problems reported within a 12 month and 7 day period respectively. Moreover, feeling of pain or discomfort in lower back, neck and shoulders prevented 18 subjects (17.4%) from performing daily activities while the 10 (9.8%) students required physical assistance during past last year. There was a statistically significant association between WMSP and gender, laboratory activity, and students work position Conclusion: It is concluded that significant number of university biomedical science students experienced musculoskeletal pain during their laboratory training activities which was found to be highly prevalent in upper extremities than lower extremities. Students reported work related musculoskeletal pain during the last 12 months respectively which has affected their daily activities. Few of them also seek medical advice by the health professionals. Students need education and awareness for better seating and safer work postures that may reduce the prevalence of musculoskeletal pain.

“…Also, understanding that one floor nurse and 2 lab nurses were left hand dominant, may help explain the increased activity on the left side during the writing tasks. It has been shown that individuals who write using their left hand use more wrist flexion than right handed individuals (Park, 2013) and this is consistent with my finding of increased flexor activity on the left side during the nursing writing tasks. The large variability (standard deviation) found between workers during tasks like handling and writing as well as the noted thumb forces (Table 5), suggests that the workers performed the same tasks differently.…”

The purpose of this thesis was to examine hand actions required of nurses and pharmacy assistants involved with chemotherapy drug administration over a work shift, and propose associated risk control strategies. There is a need to evaluate and redesign manual "pushing" and mixing of chemotherapy drugs to prevent musculoskeletal disorders and associated healthcare costs. Muscle activity of the forearm flexor and extensor muscles, and thumb forces, were measured from 5 lab nurses, 5 floor nurses and 5 pharmacy assistants who had their actions recorded throughout their shift. Lab nurses performed an average of 1.85 ± 0.48 hand efforts per min, floor nurses performed 1.62 ± 0.09 per min, while pharmacy assistants performed 5.29 ± 1.27 per min. Syringe use accounted for 17% of the pharmacy assistants' shift and 12% each for the floor and lab nurses. The tasks of drawing fluid and manually pushing treatment represented 10% of the work day. The left forearm flexors generated the highest activity over the workday and across tasks while only resting for 6% of the workday. The high number of hand efforts, combined with prolonged durations, and lack of muscular rest show evidence of muscular overload over the course of the shift as well as illustrate that the pharmacy assistants are at higher risk for WMSD. The results may also help explain the documented injury statistics and complaints associated with the arm, hand and thumb and support the implementation of a chemotherapy robot to reduce the risk associated with tasks performed by the pharmacy assistants. Further, the findings of this thesis can act as a guide for future evaluation and research of workplaces with similar syringe and hand M.Sc. Thesis -Victoria MacDonald Master University -Kinesiology v demands. The risk reducing strategies presented may also be applied to other jobs where hand and syringe use is repetitive and prolonged.

“…Pipetting was used as an ecologically valid model of short-cycle, repetitive precision work using the upper extremities (Park and Buchholz 2013). The pipetting task (see below) was performed in the laboratory by 35 right-handed female volunteers, who had at least 1-year experience in pipetting (mean 28 (SD 7) months), and were free from any shoulder pain or injury at the time of the study.…”
