Isometric and isokinetic hip strength and agonist/antagonist ratios in symptomatic femoroacetabular impingement

Abstract

Objectives This study investigated isometric and isokinetic hip strength in individuals with and without symptomatic femoroacetabular impingement (FAI). The specific aims were to: (i) determine whether differences exist in isometric and isokinetic hip strength measures between groups; (ii) compare hip strength agonist/antagonist ratios between groups; and (iii) examine relationships between hip strength and self-reported measures of either hip pain or function in those with FAI. Design Cross-sectional. Methods Fifteen individuals (11 males; 25 ± 5 years) with symptomatic FAI (clinical examination and imaging (alpha angle >55° (cam FAI), and lateral centre edge angle >39° and/or positive cros..
