Total knee arthroplasty (TKA) is the primary treatment for severe knee osteoarthritis, yet some patients continue to experience challenges such as pain, weakness, balance issues, and gait problems.
The Lie-to-Sit-to-Stand-to-Walk transfer test is a reliable assessment means in rehabilitation and fitness, effectively assessing fall risk and mobility in post-total knee replacement patients.
Total knee arthroplasty (TKA) is the primary treatment for severe knee osteoarthritis, yet some patients continue to experience challenges such as pain, weakness, balance issues, and gait problems. This study examined the validity and reliability of the Lie-to-Sit-to-Stand-to-Walk Transfer Test (LSSWT) in older adults following knee replacement surgery.
The study included twenty-two patients who had undergone TKA. Participants completed the LSSWT test, the Timed Up and Go Test (TUG) and the Hospital for Special Surgery (HSS) Knee Rating Score. To minimize fatigue, patients were given a 1-hour break between tests.
The average age of the participants was 68.1 years (± 2.59), and their mean HSS knee score was 85.43 (± 3.47). The relative reliability, measured by the intraclass correlation coefficient (ICC) coefficient, was 0.88, while the absolute reliability values were 1.21 for the standard error of measurement (SEM) and 3.33 for the smallest real difference (SRD95). The correlation coefficient of 0.63 was discovered when examining the relationship between LSSWT and TUG using the Spearman method.
LSSWT showed strong reliability and validity for assessing fall risk, dynamic stability, and range of motion in post-TKA patients. Its low minimal clinically important difference (MCID) of 3.33 indicated sensitivity to small changes. It is important to assess the risk of falling and the ability to move around for people living in the community, planning to leave the hospital, or entering a care facility.
