Recently published results showed brake reaction time among patients who underwent hip arthroscopy for femoroacetabular impingement was no different compared with preoperative times or those of control patients.

Joshua D. Harris, MD, and colleagues measured brake reaction time using the RT-2S reaction time tester in 19 patients undergoing primary hip arthroscopy to treat symptomatic femoroacetabular impingement and labral tears at a maximum of 6 weeks preoperatively and every 2 weeks postoperatively for 8 weeks. Researchers also measured sit-to-stand test at each brake reaction time testing session. Researchers selected an age- and gender-matched control group without hip or lower extremity symptoms to complete both brake reaction time and sit-to-stand tests.

Results showed no differences between preoperative and postoperative brake reaction times among patients undergoing total hip arthroscopy, as well as no differences between patients who underwent surgery and the control group. A strong negative correlation was noted between brake reaction time and sit-to-stand test preoperatively and at 4 weeks and 6 weeks postoperatively, according to results. Researchers also found a moderate negative correlation between brake reaction time and sit-to-stand test at 2 weeks postoperatively. – by Casey Tingle
