Secondary aim: studies that evaluated effects of conservative or surgical interventions on patients with FAIS using pre-post or controlled clinical trial designs. Biomechanical data must have been collected using three-dimensional motion capture devices. Reporting quality was assessed using the Epidemiological Appraisal Instrument and data were pooled (standardised mean difference (SMD), 95% CI) where populations and primary outcomes were similar.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Fourteen studies were included (11 cross-sectional and three pre\/post intervention), varying between low and moderate reporting quality. Patients with FAIS walked with a lower: peak hip extension angle (SMD \u22120.40, 95%\u2009CI \u22120.71 to \u22120.09), peak internal rotation angle (\u22120.67, 95% CI \u22121.19 to \u22120.16) and external rotation joint torque (\u22120.71, 95% CI \u22121.07 to \u22120.35), and squatted to a lesser depth with no difference in hip flexion range.
