Effects of a workplace physical exercise intervention on the intensity of headache and neck and shoulder symptoms and upper extremity muscular strength of office workers: A cluster randomized controlled cross-over trial
& NA ; The purpose of the study was to examine the effects of a workplace physical exercise intervention on the perceived intensity of headache and the intensity of symptoms in the neck and shoulders , as well as on the extension and flexion strength of the upper extremities . The study was a cluster r and omized controlled trial . The cross‐over design consisted of physical exercise intervention ( 15 weeks ) and no‐intervention ( 15 weeks ) . The subjects ( n=53 ) were office workers ( mean age 46.6 ( SD 8.4 ) ) who reported headache ( n=41 ) symptoms in the neck ( n=37 ) or shoulders ( n=41 ) , which had restricted their daily activities during the last 12 months . Pain symptoms were measured using the Borg CR10 scale and muscular strength with a 5RM test . Statistical analyses were based on linear mixed models . Physical exercise intervention result ed in a slight , but statistically significant , decrease in the intensity of headache and neck symptoms , as well as an increase in the extension strength of the upper extremities . The mean decrease in headache during the 5‐week period was 0.64 CR10 ( 95 % CI 0.28–1.00 ) ( P=0.001 ) or 49 % ( 95 % CI 22–77 ) , and 0.42 CR10 ( 95 % CI 0.11–0.72 ) ( P=0.002 ) or 49 % ( 95 % CI 13–85 ) in the intensity of neck symptoms . The mean increase in the extension strength of the upper extremities was 1.3 kg ( 95 % CI 0.5–2.1 ) ( P=0.001 ) or 4 % ( 95 % CI 1–6 ) . The intervention had no effect on the intensity of shoulder symptoms or the flexion strength of the upper extremities . Specific exercise may be clinical ly important to alleviate headache and neck symptoms
