|a Context: Hip pain is associated with impairments in postural control and balance. The Star Excursion Balance Test (SEBT) is a reliable and valid method for measuring dynamic postural control. Objective: To examine changes in dynamic postural control after hip arthroscopy and subsequent rehabilitation from baseline to 3 and 6 months postsurgery. Design: Case series. Setting: Physiotherapy department. Patients or Other Participants: Sixty-seven individuals (47 men, 20 women; age ¼ 31 6 8 years, height ¼ 1.78 6 0.09 m, mass ¼ 83 6 15 kg) scheduled for hip arthroscopy to address chondrolabral conditions were matched with 67 healthy individuals serving as controls (47 men, 20 women; age ¼ 31 6 8 years, height ¼ 1.77 6 0.09 m, mass ¼ 80 6 16 kg). The hip arthroscopy group underwent postoperative rehabilitation including SEBT training. Main Outcome Measure(s): The SEBT reach normalized to limb length was collected before surgery (baseline) and at 3 and 6 months after arthroscopy and compared with that of the healthy matched control group. Repeated-measures analysis of variance was used to evaluate whether SEBT reach differed among the 3 time points, and t tests were used to evaluate between-limbs and between-groups differences. Results: The SEBT reach in the hip arthroscopy group at baseline was less than that of the control group in all directions (P values, .001). At 3 months after arthroscopy, SEBT reach increased in the posteromedial (PM; P ¼ .007), posterolateral (PL; P, .001), and anterolateral (AL; P, .001) directions from baseline. At 6 months after arthroscopy, all directions of reach had increased (P values, .001) from baseline. The anteromedial (mean difference [MD] ¼-2.9%, P ¼ .02), PM (MD ¼-5.2%, P ¼ .002), and AL (MD ¼ -2.5%, P ¼ .04) reach distances remained shorter at 6 months after surgery in the hip arthroscopy group than in the control group. No difference existed between the control and hip arthroscopy groups for reach in the PL direction (MD ¼ -3.6%; P ¼ .06). Conclusions: Dynamic balance control in the hip arthroscopy group at baseline was poorer than in a matched control group as measured using the SEBT. At 3 months after hip arthroscopy, we observed improvements in dynamic balance in the PM, PL, and AL SEBT directions. By 6 months after arthroscopy, all directions of SEBT reach had improved, but only the PL reach improved to the level of healthy control individuals. © by the National Athletic Trainers’ Association, Inc.
