Decreased hip strength is often present in patients with chronic overuse lower extremity injuries. The hand-held dynamometer (HHD) can be used in a clinical setting to quantify hip strength; however, reliability of the device remains unclear. The purpose of this study was to determine the interexaminer and intersession reliability of a HHD when measuring isometric hip abduction (HABD) and external rotation (HER) strength, both with and without a fixed strap. The HHD had good to high reliability regardless of examiner, session, or stabilization when measuring HABD (ICC = 0.885–0.977) and HER (ICC = 0.879–0.958) isometric strength. HHD is an appropriate instrument for measuring isometric hip strength.

Proximal neuromuscular alterations are hypothesized to contribute to the patient- and disease-oriented deficits observed in CAI individuals. The objective was to compare the efficacy of two 4-week intervention programs with or without proximal joint exercises. Twenty-three individuals with CAI completed this single-blinded randomized controlled trial. Outcome measures included the Star Excursion Balance Test (SEBT) and the Foot and Ankle Ability Measure (FAAM). A time main effect was observed for the FAAM-ADL (p = .013), FAAM-Sport (p = .012), and posteromedial (p = .04) and posterolateral (p = .003) SEBT reach directions. No group main effect or time by group interaction was found. Four weeks of supervised rehabilitation improved self-reported function and dynamic balance in people with CAI.
