Abstract

Clinical Application of the Timed Up and Go Test in Total Hip Arthroplasty for Osteoarthritis of the Hip

Tomoyuki Yamauchi

The Timed Up and Go (TUG) test is a simple, widely used measure of mobility that has proven reliability in patients undergoing Total Hip Arthroplasty (THA) for osteoarthritis. This test is valuable for assessing physical function from the early postoperative period through long-term follow-up. Various studies show that TUG performance is influenced by factors such as age, body mass index, hip muscle volume and quality, phase angle, and cognitive function. On the other hand, factors like hemoglobin levels, surgical approach, and femoral stem design generally do not affect TUG results. Several interventions have been shown to improve TUG outcomes, including hip external rotator strengthening, telerehabilitation, imagery-based training, and enhanced recovery after surgery protocols. Conversely, interventions such as leg length correction, fascial manipulation, nutritional supplementation, and certain assistive devices have limited impact. Importantly, TUG has prognostic value as it can predict early hospital discharge, delayed functional recovery, long-term muscle deficits, and the ability to return to driving. These findings highlight the test’s relevance beyond simple mobility assessment, extending to activities of daily living and social participation. In conclusion, the TUG test is a versatile and reliable tool that can guide postoperative rehabilitation and evaluate the effectiveness of interventions, with comprehensive assessment including muscle strength, muscle quality, and cognitive status optimizing patient recovery after THA.
