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

4. juni 2026 opdateret af: Mohamed Hazem Abdelhakam Elshafey, Cairo University

The Relationship Between Chronic Non-Specific Low Back Pain and Isokinetic Performance of Ankle Joint Muscles

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 (Haile et al., 2021). 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 (Leung et al., 2015). Ankle muscle performance of individuals with LBP during gait becomes more clinically important as it may provide insights into the mechanisms of ankle strategies (Claeys et al., 2015). 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 (Bonetti et al., 2018).
