Effectiveness of Combined Stretching and Strengthening Exercise Using Rehabilitation Exercise System with a Linear Actuator and MR Damper on Static and Dynamic Sitting Postural Balance: A Feasibility Study

Postural imbalance induced by prolonged sitting can be improved exercise therapy. The aim of study was to evaluate the influence combined stretching and strengthening using rehabilitation system with a linear actuator MR damper on static dynamic postural balance. Twelve subjects who sit almost 10 h day participated in this study. manufactured provide exercise. All were asked perform an program that designed enhance balance tight muscle weakened muscle. Body pressure distributions analyzed for mean force seat sensor system. Trunk activities measured attaching surface electrodes thoracic erector spinae, lumbar multifidus data divided into two regions (dominant non-dominant side) under four conditions: no pelvic tilt, lateral anterior posterior tilt. trunk compared between before after performing conditions. Both conditions, there significant differences body DS NDS (p < 0.01). After exercise, increased dominant side while those decreased significantly In addition, all muscles non-predominant 0.01 p 0.05). These results showed decreasing distribution activity From study, we concluded is suitable providing it could helpful maintain correct posture enhancing during sitting.
