Background and Objectives: Low back pain is a musculoskeletal disorder with an annual prevalence of 18.6%. The aim of the present study was to evaluate the effect of rehabilitation with medicine ball on directed and general co-contraction of knee joint muscles in low back patients during walking,
Materials and Methods: The present study was a clinical trial. The statistical population of the present study included patients with low back pain in the age range of 20-30 years in Ardabil in 1399. Participants in the study included 20 men with low back pain, who were randomly assigned (names were placed in a bag and identified randomly and one among extracts and groups) in two The exercise group and the control group were divided. The training group performed 12 sessions of strengthening exercises of the central muscles of the body with the beta medicine ball. Selected muscle activity during walking was recorded in two groups during pre- and post-test
Results: Findings demonstrated that general contraction during loading and mid-stance phases increased significantly at post-test than that pre-test. Paired wise comparison demonstrated that directed flexor/extensor knee joint contraction during push off phase increased significantly.
Conclusion: Exercise therapy with medicine ball improved directed and general co-contraction of knee joint muscles in low back pain patients during walking.
