Background: Limited knee flexion and increased muscle co-contraction during jump landing are believed to diminish outcomes after anterior cruciate ligament (ACL) reconstruction. The efficacy of jump training to improve patients’ mechanical and neuromuscular deficits is understudied. Hypothesis: Jump training will improve functional, mechanical, and neuromuscular outcomes and higher repetition training augmented by body weight support will result in better retention of gains. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Thirty athletes (18 months after surgery) were screened, and 19 with mechanical deficits and limited clinical outcomes were enrolled in the trial. Testing included the International Knee Documentation Committee (IKDC) questionnaire, leg landing mechanics via motion analysis, knee joint effusion using a stroke test, and a surface electromyography–generated co-contraction index during a single-legged landing. Participants were randomly assigned to 1 of 2 groups: jump training with normal body weight (JTBW) and high-repetition jump training with body weight support (JTBWS). Knee effusion grading throughout training was used to assess joint tolerance. Changes in outcomes over time were analyzed with mixed-effects modeling. Immediate outcomes were compared with retention testing at 8 weeks after training by use of 2-way analyses of variance with effects of time and group. Results: Significant effects of time were found during the training phase for all outcome measures, but no effects of group or sex were found. IKDC score (pooled; mean ± SD) increased from 76 ± 12 to 87 ± 8 ( P < .001). Knee flexion during single-legged landing increased from 57° ± 11° to 73° ± 9° ( P < .001). Average co-contraction index decreased from 37 ± 15 to 19 ± 6 ( P < .001). All measures were retained over the retention period in both groups. The relative risk of knee effusion of the JTBW group versus the JTBWS group was 4.2 (95% CI, 2.25-7.71; P < .001). Conclusion: Jump training mitigated some risk factors for second injury and osteoarthritis in patients after ACL reconstruction. Training made lasting improvements in physical function measures as well as mechanical and neuromuscular coordination deficits. Higher repetitions used with body weight support did not improve retention but substantially reduced risk for effusion. Clinical Relevance: Jump training is an efficacious intervention for athletes with poor outcomes after ACL reconstruction, and training with body weight support lessens the risk for excessive joint stress during practice.

Objective: To compare the effect of Tai Chi training with conventional exercise on dual-tasking performance among stroke survivors. Design: An assessor-blinded, randomized controlled trial. Subjects: Community-dwelling stroke survivors. Setting: Community centers and university. Interventions: Subjects in the Tai Chi group and the conventional exercise group were trained with the corresponding exercises for 12 weeks (1 hour/session, 2/week). No training was given to the controls. Main measures: An auditory Stroop test, a turning-while-walking test, and a dual-tasking condition that combined the two tests were conducted at baseline, after the intervention, and one month later. Results: Forty-seven subjects were randomized into Tai Chi group ( n = 15), conventional exercise group ( n = 17), or control group ( n = 15). There was no significant difference in the outcome measures among the three groups after the intervention and at the one month follow-up assessment. Within-group comparisons showed improvements in dual-tasking performance after Tai Chi training and further improvement during the follow-up period (composite score on the auditory Stroop test: pre-assessment: 73.1 ± 27.6, post-assessment: 89.9 ± 23.4, follow-up assessment: 91.7 ± 26.9; completion time of the turning-while-walking test: pre-assessment: 17.7 ± 6.9 seconds, post-assessment: 15.6 ± 5.2 seconds, follow-up assessment: 14.9 ± 4.9 seconds). Conclusion: Tai Chi training does not have superior effect on dual-tasking performance compared with conventional exercise among stroke survivors. Further studies with larger sample size, longer training, and follow-up periods are needed.

Abstract Background The rate of falls in patients after total knee arthroplasty (TKA) is high and related to lower limb muscle weakness and poor balance control. However, since routine post-TKA rehabilitation is uncommon, it is paramount to explore alternative strategies to enhance balance and physical functioning in post-TKA patients. As Tai Chi is a proven strategy for improving balance in older people, the proposed study aims to determine the feasibility and acceptability of a 12-week community-based post-TKA multimodal Tai Chi program and to collect preliminary data with respect to the efficacy of such a program in improving balance and physical functioning in post-TKA patients as compared to usual postoperative care. Methods A single-blinded 2-arm pilot randomized controlled trial will recruit 52 community-dwelling post-TKA patients (aged > 60 years) in Hong Kong. In addition, 26 untreated asymptomatic controls will be recruited for comparison purposes. The TKA patients will be randomized into either a 12-week multimodal Tai Chi rehabilitation group or a postoperative usual care group (26 each). Participants will perform the outcome assessments at baseline, 6, 12, 24, and 52 weeks after TKA, while asymptomatic controls will have the same assessments at baseline, 12, and 52 weeks after baseline. The rate of recruitment, retention, and attrition, as well as adherence to the intervention, will be measured and used to determine the feasibility of the study and whether a full-scale effectiveness trial is warranted. Further, qualitative interviews will be conducted to explore the acceptability and possible barriers to the implementation of the intervention. Primary and secondary outcomes including both patient-reported surveys and performance-based tests will be compared within and between groups. Discussion The study will determine the feasibility and acceptability/potential efficacy of community-based rehabilitation for post-TKA patients and assess whether the intervention has the potential to be assessed in a future fully powered effectiveness trial. The findings will also be used to refine the study design and guide the conduction of a future definitive randomized controlled trial. Trial registration ClinicalTrials.gov NCT03615638.
