Résumé : |
"Objective To investigate which of the 2 muscle-impairment measures for the operated leg, normalized knee extension strength or leg press power, was most closely associated with performance-based and self-reported measures of function shortly after total knee arthroplasty (TKA). Design Cross-sectional, exploratory study. Setting Laboratory at a regional hospital. Participants Individuals (N=39) with an average age + SD of 65.5+10.3 years, who all had unilateral TKA 28 days prior. Interventions None. Main Outcome Measures The patients performed maximal isometric knee extensions and dynamic leg presses to determine their body-mass normalized knee extension strength and leg press power, respectively. The 10-meter fast speed walking- and 30-second chair stand tests were used to determine performance-based function, while the Western Ontario and McMaster Universities Osteoarthritis Index and Oxford Knee Scores were used to determine self-reported function. Results Normalized leg press power was more closely associated with both performance-based (r=.82, P<.001 and self-reported p=".002)" measures of function compared with normalized knee extension strength r=".39," respectively> Conclusions Normalized leg press power was more closely associated with both performance-based and self-reported function early after TKA than normalized knee extension strength. It may be explained by the fact that performance-based measures of function are typically closed kinetic chain tasks, such as walking or rising from a chair, and self-reported measures of function typically include questions that address perceived difficulty with performing these same tasks." |
