The efficacy of preventive physiotherapy practices on forward head posture and upper extremity work-related functions among office workers with neck pain

In the present study, it was aimed to investigate the efficacy of Preventive Physiotherapy Practices (PPP) that are intended for work-related musculoskeletal disorders (MSD), posture training, ergonomic arrangements, exercise, and EMG biofeedback (EMG-B) training on Forward Head Posture (FHP), and upper extremity work-related functions among office workers with neck pain. 51 office workers with neck pain, under the age of 40, active full-time employees for the past 1 year were included in the study. All individuals received posture training and ergonomic arrangements in their workplace. Three groups, EMG-B, Exercise, and Control, with 17 individuals in each group, were formed. EMG-B and Exercise training were performed for 6 weeks, 3 days a week. Pain (NDI and NPAD), postüre (FHP and RULA), upper extremity functionality (DASH T/W, Constant-Murley Score), task performance (keyboard/ mouse tasks), and Upper Trapezius (UT) muscle activation (sEMG) were assessed pre-post study. According to the findings obtained; significant differences were observed in all parameters except task performance and muscle activation in 3 groups. UT muscle activation decreased only in the EMG-B group (p<0.01); In the Exercise group, FHP and neck disability was found to be lower than the other groups (p<0.01). There was no significant difference between the groups in RULA and upper extremity functionality (p>0.05). In addition, determined that FHP was correlated with neck pain, mouse task speed, and UT activity (p<0.05). Individualized posture training and ergonomic arrangements given by physiotherapists for office workers showed positive effects on pain, posture, and work-related functions. It would be beneficial to support the program with exercise training when a more effective treatment is aimed on FHP and pain, and with EMG-B to reduce UT muscle activity. Further studies are needed to examine the long-term effects and psychosocial parameters of PPP.
