Development and Efficacy of a Novel, Cost-Effective Gait Training Device Utilized at Home for Stroke Survivors

This pilot, parallel-group randomized controlled trial will evaluate the feasibility, safety, usability, and preliminary efficacy of the Rise\&Walk InHome (RWH), a novel robotic gait training device designed for home use after stroke. Twenty adults with lower-extremity motor impairment following a first-ever stroke (3 months to 5 years post-event) will be randomized 1:1 to either (1) RWH-assisted home walking plus usual care or (2) usual care alone for 12 weeks. Participants in the intervention group will receive an in-home RWH device, complete a structured device training program, and be instructed to perform 30-minute RWH walking sessions four times per week (48 sessions total). All participants will undergo standardized outcome assessments at baseline, weeks 4, 8, and 12, including the 6-Minute Walk Test (primary outcome), 10-Meter Walk Test, daily step count via wearable activity tracker, and health-related quality of life (SF-36). Additional feasibility and usability outcomes include device use and adherence, patient satisfaction and motivation, ease of use, perceived exertion, and adverse events. Findings will inform the feasibility of in-home deployment of the RWH device and provide preliminary effect-size estimates to guide the design of a larger efficacy trial.

tACS for Sensory Motor Recovery After Stroke

The overall goal is to investigate the effectiveness of a novel intervention - transcranial alternating current stimulation (tACS) for motor recovery in stroke survivors.

Safety and Efficacy Study of Implantable Neuromodulation for Poststroke Hemiplegia

Background: Hemiplegia is a common complication after a stroke. Studies have shown that traditional medical and rehabilitation treatments are not good for improving patients' motor function, deep brain stimulation (DBS) and vagus nerve stimulation (VNS) can improve the motor function of patients, but there is no comparative study between them. Objectives: This study compares the efficacy and safety of DBS and VNS in the recovery of motor function in patients with post-stroke hemiplegia, determining the best treatment for patients with post-stroke hemiplegia, and providing high-level clinical evidence for patients and clinicians to choose from. Methods/Design: This is a randomized, double-blind, sham-controlled, cross-controlled pilot study. A total of 98 patients with post-stroke hemiplegia are assigned to receive DBS or VNS. After 3 and 6 months of follow-up, all the devices are turned off. After a 2-week washout, the control group is turned on, but the stimulation group is given sham stimulation. After 9 and 12 months of follow-up, all the devices are turned on. Then, at postoperative 15 and 18 months, postoperative neuroimaging and various post-stroke motor-related scores were performed for data collection and analysis. Discussion: We propose a study design and rationale to compare the efficacy and safety of DBS and VNS in patients with post-stroke hemiplegia to provide evidence and reference for implantable neuromodulation in the treatment of post-stroke dysfunction, and to compare the therapeutic effects of DBS and VNS to provide evidence for patient and clinical diagnosis and treatment choices. Study limitations are related to the small sample size and short study period.
