Effects of early virtual reality-based rehabilitation in patients with total knee arthroplasty: A randomized controlled trial.

ABSTRACT: BACKGROUND:Virtual reality (VR)-based rehabilitation is a promising approach for improving recovery in many conditions to optimize functional results, enhancing the clinical and social benefits of surgery. OBJECTIVE:To assess the efficacy of an early rehabilitation performed by the VR-based rehabilitation versus the traditional rehabilitation provided by physical therapists after primary total knee arthroplasty (TKA). METHODS:In this randomized controlled clinical trial, 85 subjects met the inclusion criteria and were randomized 3 to 4 days after TKA to an inpatient VR-based rehabilitation and a traditional rehabilitation. Participants in both groups received 60?minutes/day sessions until discharge (around 10 days after surgery). The primary outcome was the pain intensity. The secondary outcomes were: the disability knee, the health related quality of life, the global perceived effect, the functional independent measure, the drugs assumption, the isometric strength of quadriceps and hamstrings, the flexion range of motion, and the ability to perform proprioception exercises. Outcomes were assessed at baseline (3-4 days after TKA) and at discharge. RESULTS:VR-based or traditional rehabilitation, with 13% of dropout rate, shown no statistically significant pain reduction between groups (P?=?.2660) as well as in all other outcomes, whereas a statistically significant improvement was present in the global proprioception (P?=?.0020), in favor of the VR-based rehabilitation group. CONCLUSIONS:VR-based rehabilitation is not superior to traditional rehabilitation in terms of pain relief, drugs assumptions and other functional outcomes but seems to improve the global proprioception for patients received TKA. LEVEL OF EVIDENCE:Therapy, level 1b. CONSORT-compliant. TRIAL REGISTRATION:http://www.clinicaltrials.gov, ClinicalTrials.gov, NCT02413996.

Project description:BackgroundPhysical therapy is regarded as an essential aspect in achieving optimal outcomes following total knee arthroplasty (TKA). The coronavirus disease 2019 (COVID-19) pandemic has made face-to-face rehabilitation inaccessible. Virtual reality (VR) is increasingly regarded as a potentially effective option for offering health care interventions. This systematic review and meta-analysis investigate VR-based rehabilitation's effectiveness on outcomes following TKA.MethodsFrom inception to May 22, 2021, PubMed/Medline, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Scopus, PsycINFO, Physiotherapy Evidence Database, China National Knowledge Infrastructure, and Wanfang were comprehensively searched to identify randomized controlled trials (RCTs) evaluating the effect of VR-based rehabilitation on patients following TKA according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane Handbook for Systematic Reviews of Interventions.ResultsEight studies were included in the systematic review, and seven studies were included in the meta-analysis. VR-based rehabilitation significantly improved visual analog scale (VAS) scores within 1 month (standardized mean difference [SMD]: -0.44; 95% confidence interval [CI]: -0.79 to -0.08, P = 0.02), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) within 1 month (SMD: -0.71; 95% CI: -1.03 to -0.40, P < 0.01), and the Hospital for Special Surgery Knee Score (HSS) within 1 month and between 2 months and 3 months (MD: 7.62; 95% CI: 5.77 to 9.47, P < 0.01; MD: 10.15; 95% CI: 8.03 to 12.27, P < 0.01; respectively) following TKA compared to conventional rehabilitation. No significant difference was found in terms of the Timed Up and Go (TUG) test.ConclusionsVR-based rehabilitation improved pain and function but not postural control following TKA compared to conventional rehabilitation. More high-quality RCTs are needed to prove the advantage of VR-based rehabilitation. As the COVID-19 pandemic continues, it is necessary to promote this rehabilitation model.

Project description:ObjectiveFew effective treatments improve upper extremity (UE) function after stroke. Immersive virtual reality (imVR) is a novel and promising strategy for stroke UE recovery. We assessed the extent to which imVR-based UE rehabilitation can augment conventional treatment and explored changes in brain functional connectivity (FC) that were related to the rehabilitation.MethodsAn assessor-blinded, parallel-group randomized controlled trial was performed with 40 subjects randomly assigned to either imVR or Control group (1:1 allocation), each receiving rehabilitation 5 times per week for 3 weeks. Subjects in the imVR received both imVR and conventional rehabilitation, while those in the Control received conventional rehabilitation only. Our primary and secondary outcomes were the Fugl-Meyer assessment's upper extremity subscale (FMA-UE) and the Barthel Index (BI), respectively. Both intention-to-treat (ITT) and per-protocol (PP) analyses were performed to assess the effectiveness of the trial. For both the FMA-UE/BI, a one-way analysis of covariance (ANCOVA) model was used, with the FMA-UE/BI at post-intervention or at follow-up, respectively, as the dependent variable, the two groups as the independent variable, baseline FMA-UE/BI, age, sex, site, time since onset, hypertension and diabetes as covariates.ResultsBoth ITT and PP analyses demonstrated the effectiveness of imVR-based rehabilitation. The FMA-UE score was greater in the imVR compared with the Control at the post-intervention (mean difference: 9.1 (95% CI 1.6, 16.6); P = 0.019) and follow-up (mean difference:11.5 (95% CI 1.9, 21.0); P = 0.020). The results were consistent for BI scores. Moreover, brain FC analysis found that the motor function improvements were associated with a change in degree in ipsilesional premotor cortex and ipsilesional dorsolateral prefrontal cortex immediately following the intervention and in ipsilesional visual region and ipsilesional middle frontal gyrus after the 12-week follow-up.ConclusionsImVR-based rehabilitation is an effective tool that can improve the recovery of UE functional capabilities of subacute stroke patients when added to standard care. These improvements were associated with distinctive brain changes at two post-stroke timepoints. The study results will benefit future patients with stroke and provide evidence for a promising new method of stroke rehabilitation.Trial registrationClinicalTrials.gov identifier: NCT03086889.

Project description:BackgroundThe recovery of quadriceps muscle force and function after total knee arthroplasty (TKA) is suboptimal, which predisposes patients to disability with increasing age.ObjectiveThe purpose of this investigation was to evaluate the efficacy of quadriceps muscle neuromuscular electrical stimulation (NMES), initiated 48 hours after TKA, as an adjunct to standard rehabilitation.DesignThis was a prospective, longitudinal randomized controlled trial.MethodsSixty-six patients, aged 50 to 85 years and planning a primary unilateral TKA, were randomly assigned to receive either standard rehabilitation (control) or standard rehabilitation plus NMES applied to the quadriceps muscle (initiated 48 hours after surgery). The NMES was applied twice per day at the maximum tolerable intensity for 15 contractions. Data for muscle strength, functional performance, and self-report measures were obtained before surgery and 3.5, 6.5, 13, 26, and 52 weeks after TKA.ResultsAt 3.5 weeks after TKA, significant improvements with NMES were found for quadriceps and hamstring muscle strength, functional performance, and knee extension active range of motion. At 52 weeks, the differences between groups were attenuated, but improvements with NMES were still significant for quadriceps and hamstring muscle strength, functional performance, and some self-report measures.LimitationsTreatment volume was not matched for both study arms; NMES was added to the standard of care treatment. Furthermore, testers were not blinded during testing, but used standardized scripts to avoid bias. Finally, some patients reached the maximum stimulator output during at least one treatment session and may have tolerated more stimulation.ConclusionsThe early addition of NMES effectively attenuated loss of quadriceps muscle strength and improved functional performance following TKA. The effects were most pronounced and clinically meaningful within the first month after surgery, but persisted through 1 year after surgery.

Project description:BackgroundThe purpose of this study was to assess the effect of preoperative physiotherapy (PT) on functional, subjective and socio-economic parameters after total knee arthroplasty (TKA).Methods20 patients (mean ± SD: age 67 ± 7 years) scheduled for TKA at Balgrist University Hospital between July 2016 and March 2017 were randomly assigned to a control (CG) or intervention (IG) group. 3 to 4 weeks prior to surgery the IG completed 5 to 9 sessions of PT containing proprioceptive neuromuscular facilitation (PNF) techniques, endurance training and individually indicated interventions. Measurements were executed at baseline, preoperative and 3 months after TKA. The primary outcome measure was the Stair Climbing Test (SCT), secondary outcome measures were the knee range of motion (ROM) and the level of physical activity using Lysholm Score (LS) and Tegner Activity Scale (TAS). The subjective and socio-economic parameters were the Patients' Global Impression of Change (PGIC) scale, inpatient rehabilitation time, preoperative pain levels and metabolic equivalent (MET), postoperative intake of analgesics and overall costs.ResultsNo difference between IG and CG was found for SCT (F (2/36) = 0.016, p = 0.984, η2 = 0.004). An interaction between group and time was shown for TAS (F (18/1) = 13.890) with an increase in the IG (p = 0.002, η2 = 0.536). The sub-item "pain" within the LS presented a higher pain-level in CG (F (18/1) = 4.490, p = 0.048, η2 = 0.974), while IG showed a higher preoperative MET compared to CG (p = 0.035). There were no other significant changes. The CG produced 21.4% higher overall costs, took more analgesics and showed higher preoperative pain levels than the IG.ConclusionsFindings show that preoperative therapy improved the level of physical activity before and after TKA and resulted in a clinically relevant gain in TAS.Trial registrationClinicalTrials.gov Identifier; NCT03160534.
