Abstract: (299 Views)
Purpose: Low back pain (LBP) is a health problem. Rehabilitation could be a suitable therapy for LBP patients. Nonetheless, the effectiveness of movement pattern training on LBP patients was not assessed from scientific point of view. So, this research was done to assess the effects of movement pattern exercise on general lower limb muscular co-contraction in non-specific chronic LBP patients during walking.
Methods: The current research was semi-experimental. Forty male adults who experienced non-specific chronic LBP willingly enrolled in this study. Twenty samples were divided in intervention and control groups. Exercises protocol used in this study were based on that introduced by Harris-Hayes et al. for 18 supervised training sessions (during 6-weeks). The assessments were conducted before the intervention and again after six weeks. General co-contraction of the lower limb muscles were recorded by electromyography data while walking. General co-contraction was calculated by the total activation of the muscles abounded the joint.
Results: The findings indicated a significant decrease of general co-contraction of the ankle in intervention group at propulsion (p=0.011 ƞ2= 0.160). Also, the results showed that at loading phase, general knee co-contraction was greater in experimental compared with control group (p=0.037 ƞ2=0.110).
Conclusions: Our research revealed that the training program improve the general co-contraction of the lower limb muscles in individuals with LBP.
