A cross sectional study to determine the risk factors of work-related musculoskeletal disorders among physical therapists in Metro Manila

See More

Methods This cross-sectional study was done in selected hospitals in Metro Manila with the approval of the Ethics Review Committee. Licensed physical therapist were recruited using a purposive sampling technique. The Personal Demographic Sheet, Ovako Work Posture Analyzing System, MM040 Questionnaire were used to determine, assess and describe the participants' demographic profile, working conditions and environment, respectively. The Standard Nordic Musculoskeletal Questionnaire was used to determine the presence of work-related musculoskeletal disorders among the respondents. A Marascuilo table of statistics was used to determine the person-tasks-environment relationship to work-related musculoskeletal disorders.

Results Twenty-eight physical therapists participated in the study. Subjects perceived their working environment as good to very good in terms of temperature, cleanliness, noise and light. The common work-related musculoskeletal disorders involved the upper extremities and back. Gender, number of co-workers, years of service, BMI, and category 2 and 4 postures were associated with work-related musculoskeletal disroders among subjects in the last 12 months. Years of service, number of co-workers and cleanliness were associated with symptoms in the last 7 days. Gender, BMI, temperature, and category 2 and 4 postures prevented the subjects from working.

Conclusion The factirs commonly associated with work-related musculoskeletal disorders involving mostly the upper extremities and back are gender, BMI, number of co-workers and years of service. Work-related musculoskeletal disorders involving the neck, shoulder, upper and lower back prevented the therapists from doing their work.
