Effects of Weight-Bearing Biofeedback Training on Functional Movement Patterns Following Total Knee Arthroplasty: A Randomized Controlled Trial.

ABSTRACT: Randomized controlled trial.To examine the effects of weight-bearing biofeedback training on weight-bearing symmetry and functional joint moments following unilateral total knee arthroplasty.Individuals after unilateral total knee arthroplasty place more weight on the nonsurgical limb compared to the surgical limb during function. It is unknown whether targeted intervention can improve function in the surgical limb and resolve altered movement patterns.Twenty-six patients were randomly assigned to 2 groups (reload or control). The reload group had a standard-of-care rehabilitation augmented with weight-bearing biofeedback training, and the control group had a dose-matched standard-of-care rehabilitation. Lower-limb weight-bearing ratios were measured preoperatively and 6 and 26 weeks after total knee arthroplasty during a 5-time sit-to-stand test (FTSST) and walking. Secondary outcomes were FTSST time, walking speed, and lower-limb joint moments during the FTSST and walking.No between-group differences were found in weight-bearing ratios. Five-time sit-to-stand test time improved in the reload group compared to the control group at 6 (P = .021) and 26 weeks (P = .021). There were no between-group differences in knee extension moment during the FTSST. Surgical-limb knee extension moments during walking increased from baseline to 26 weeks in the reload group and decreased in the control group (P = .008).Weight-bearing biofeedback training had no effect on functional weight-bearing symmetry or knee extension moments during the FTSST. However, the biofeedback training resulted in increases of knee extension moments during gait and improved FTSST times. Trial registered at ClinicalTrials.gov (NCT01333189). Level of Evidence Therapy, level 2b.

Project description:BackgroundLoading and contraction failure (muscular exhaustion) are strength training variables known to influence neural activation of the exercising muscle in healthy subjects, which may help reduce neural inhibition of the quadriceps muscle following total knee arthroplasty (TKA). It is unknown how these exercise variables influence knee pain after TKA.ObjectiveTo investigate the effect of loading and contraction failure on knee pain during strength training, shortly following TKA.DesignCross-sectional study.SettingConsecutive sample of patients from the Copenhagen area, Denmark, receiving a TKA, between November 2012 and April 2013.ParticipantsSeventeen patients, no more than 3 weeks after their TKA.Main outcome measuresIn a randomized order, the patients performed 1 set of 4 standardized knee extensions, using relative loads of 8, 14, and 20 repetition maximum (RM), and ended with 1 single set to contraction failure (14 RM load). The individual loadings (kilograms) were determined during a familiarization session >72 hours prior. The patients rated their knee pain during each repetition, using a numerical rating scale (0-10).ResultsTwo patients were lost to follow up. Knee pain increased with increasing load (20 RM: 3.1±2.0 points, 14 RM: 3.5±1.8 points, 8 RM: 4.3±2.5 points, P = 0.006), and repetitions to contraction failure (10% failure: 3.2±1.9 points, 100% failure: 5.4±1.6 points, P<0.001). Resting knee pain 60 seconds after the final repetition (2.7±2.4 points) was not different from that recorded before strength training (2.7±1.8 points, P = 0.88).ConclusionBoth loading and repetitions performed to contraction failure during knee- extension strength-training, increased post-operative knee pain during strength training implemented shortly following TKA. However, only the increase in pain during repetitions to contraction failure exceeded that defined as clinically relevant, and was very short-lived.Trial registrationClinicalTrials.gov NCT01729520.
