Effects of balance training on functional outcome after total knee replacement in patients with knee osteoarthritis: a randomized controlled trial

Abstract

Additional balance training exerted a significant beneficial effect on the function recovery and mobility outcome in patients with knee osteoarthritis after total knee replacement.

Body Mass Index and Functional Mobility Outcome Following Early Rehabilitation After a Total Knee Replacement: A Retrospective Study in Taiwan

“…Because being overweight or obese is a risk factor for poor postural stability (56)(57)(58), and because changes in body weight influence balance control (59,60), it is reasonable to expect that overweight and obese patients perform more poorly in the FRT and SLS test compared with patients with a normal BMI, because such tasks are highly dependent on postural stability and balance control. Previous studies have shown that the performance of postural stabilitydependent mobility tasks improves after balance-based post-TKR rehabilitation (24,38), which is consistent with the significant improvements in the FRT and SLS test results for all of the BMI groups at the 2-month and 6-month post-TKR followup assessments in the current study.…”

“…Performance-based tasks, such as the FRT, SLS test, TUG test, CRT, TMWT, and SCT, are used as measures to evaluate balance and mobility outcomes following post-TKR rehabilitation (18,20,21,24,38,(49)(50)(51). However, the impact of a high BMI on such clinical outcomes has not been clarified completely.…”

“…A flowchart showing the patient selection process and the study group assignments is shown in Figure 1. In a previous study by our group, the effect sizes calculated for an exercise training regimen were ;0.4 for both balance and functional mobility measures (24). We used G*Power 3 (35) to estimate the sample size required for our current study.…”

“…Previous studies have demonstrated that early rehabilitation following TKR surgery can improve functional mobility, including walking and stair climbing, regardless of the training protocols used (20)(21)(22)(23)(24). However, obesity is associated with limited recovery in functional activities within a short-term followup period (13)(14)(15), and whether BMI influences early mobility outcomes following post-TKR rehabilitation remains unclear.…”

“…Outpatient rehabilitation was initiated immediately after inpatient discharge. The rehabilitation program consisted of 2 months of supervised outpatient therapy, which followed a previously described rehabilitation program that consisted of functional and balance training (24). The functional training consisted of warm-up, strengthening exercises, functional task-oriented exercises, endurance exercises, and cool-down (21).…”
