Isokinetic Profile of Ankle Joint Muscles in Chronic Non Specific Low Back Pain Patients

Recruiting now

Conditions studied: Chronic Non-specific Low Back Pain

In brief

Chronic non-specific low back pain and its resulting infirmity have become a huge health and socioeconomic burden. Low back pain is reportedly associated with decreased activities of daily living and quality of life. Previous literature supports the presence of a link between CLBP and lower limb kinematics that can contribute to functional limitations and disability. For example, CLBP commonly coexist with postural and structural asymmetry. Ankle muscle performance of individuals with LBP during gait becomes more clinically important as it may provide insights into the mechanisms of ankle strategies. The isokinetic testing is an assessment method of high effectivity and trustworthiness that can be used to compare bilateral and agonist/ antagonist ankle muscles strength of normal subjects and athletes. It can be used to analyze muscular performance and differences in muscle performance between dominant and non-dominant limbs.
