| Objectives Using exercise therapy to treat the therapists with work-related musculoskeletal disorders(WRMDs);To evaluate the effects of the exercise therapy for the intervention of WRMDs among therapists;To observe the influence of exercise therapy on the intensity of pain,muscle strength and the ability to resist fatigue;To provide the therapists with a simple and practical method.Methods 60 therapists with WRMDs in neck,shoulder and upper back were recruited from several hospitals in tang shan to receive eight weeks of intervention.A randomized controlled trial with one intervention group(IG=30)and a control group(CG=30)was used to evaluate the effects of intervention among therapists.Participants in the IG were instructed to perform a standardized exercise program 20min/session,1 time/day,5 days/week for 8 weeks.At the same time,the control group solely took a break and did not receive any form of specific intervention.The exercise programs included: 1 Warm-up exercises: joint movement and stretching;2 Training the muscular strength and endurance of the neck,shoulder and upper back.Visual analogue scale(VAS)and surface electromyography(MVC,RMS,MF)were assessed in both groups at preintervention,4 and 8 weeks after intervention.The data collected were analyzed with repeated measures ANOVA.Results 1 Intergroup analysis showed no statistically significant difference before intervention(P>0.05),statistically significant after 4-week intervention in left neck MVC and RMS and right shoulder RMS(P<0.05),and statistically significant after 8-week intervention in all outcomes(P<0.05).2 Intragroup analysis showed no statistically significant improvement in the control group(P>0.05),and statistically significant improvement in the intervention group(P <0.05).Conclusion Exercise therapy intervention after work can effectively relieve pain,improve muscle strength and the ability to resist fatigue,so as to improve work-relatedmusculoskeletal disorders,and more effectively after 8 weeks. |
