Objectives : This study was performed to investigate of prevalence rate of musculoskeletal symptoms and its
related factors in male physical therapists.
Methods : A self-administered questionnaire survey was conducted to 461 male physical therapists in Korea.
Definition of musculoskeletal symptoms is moderate pain (when they have pain in physical therapy for patients but if they get back home, rest and should be becomes recovery) at which above 1 anatomical areas of neck, shoulder, arm/elbow, hand/wrist/fingers, low back, leg/foot at last 1 year.
Results : The prevalence rate of musculoskeletal symptoms at which above 1 anatomical area was 49.9%, and were showed high on the low back 27.8%, shoulder 23.6% but hand/wrist/fingers (14.1%), neck (13.0%), leg/foot (10.2%), arm/elbow (9.3%) showed low. The prevalence rate of musculoskeletal symptoms at which above 1 anatomical area was in a statistically significant higher with group of sleeping hours are less than 7 hours per day (p<0.05), stressful (p<0.01), the more motions that bend or twist the waist (p<0.01), the more volume of works (p<0.05), manipulation treatment are more than 11 patient per day (p<0.01), number of exercise treatment are more than 16 patient per day (p<0.01), number of transfer from wheel chair to bed are more than 6 patient per day (p<0.01), have a separated therapy room (p<0.05), not put on the desk or arm holder for arm at sitting work (p<0.05). In multiple logistic regression to control confounding factors by interrelated independent variables, the significant risk factors (OR; odds ratio) of musculoskeletal symptoms at each anatomical area were as follows; exercise for shoulder (OR=1.792, p<0.05); stress for neck (OR=1.213, p<0.05), shoulder (OR=1.669, p<0.05) and hand/wrist/fingers (OR=2.454, p<0.01); work hours per week for neck (OR=2.494, p<0.05) and shoulder (OR=3.567, p<0.01); bending or twist motion of waist for neck (OR=2.319, p<0.05), shoulder (OR=2.721, p<0.01), low back (OR=1.918, p<0.05) and above 1 region (OR=2.735, p<0.01); work duration for shoulder (OR=1.893, p<0.05), low back (OR=2.580, p<0.01) and above 1 region (OR=1.698, p<0.05); number of manipulation treatment per day for above 1 region (OR=2.009, p<0.01); number of exercise a patient per day for arm/elbow (OR=2.365, p<0.01); Back spine straight at sitting work for shoulder (OR=1.706, p<0.05).
Conclusions : The prevalence rate of musculoskeletal symptoms in male physical therapists were generally high, and main cause were related to working factors with when they did repeated many times of bending or twist of waist and number of manipulation treatment, stress and work volume, lifting patients, uncomfortable pose and worktable, separated therapy room. Therefore, it is necessary to improve working environment with working time, treatment technique, physical therapy activity, comfortable pose and worktable for the prevention of musculoskeletal symptoms of male physical therapists.
