Measure Timed Up and Go (TUG) Prior to
Total Hip Arthroplasty
TUG < 10 seconds was found to predict ability to walk without assistive device 6 months post-THA.
The TUG test:
The TUG measures the time (in seconds) that a patient requires to stand up from an armless chair (chair seat height=45 cm), walk a distance of 3 m, turn, walk back to the chair, and sit down. The test is performed with the participants wearing shoes and walking at their maximum speed without any assistive devices.
A TUG score < 10 seconds prior to surgery means patients undergoing THA, will likely not require assistive device at 6 months post-THA.
Positive predictive value of 92%.Â Â Â Â Â Â Â Negative predictive value of 80%.
Will improving the TUG score (to less than 10 seconds) with preoperative training improve ambulatory ability after THA?
Further research is needed to answer this question. The results of this study do provide direction for preoperative treatment of this population. The TUG test involves the functional activities of standing from a chair, sitting to a chair, walking, and turning. Thus focusing on such activities should provide better improvement in daily activities, compared to an impairment-based program.
