Effectiveness of Telerehabilitation-Delivered LSVT-BIG on Motor Function in Chronic Stroke Patients: A Single-Subject Experimental Study.
LSVT-BIG done over Zoom four times a week lifts gait, balance, and arm use in chronic stroke.
01Research in Context
What this study did
Three adults who had a stroke at least six months ago joined the study.
Each person did LSVT-BIG moves four times a week for one hour on Zoom.
The team used an ABAB design: treatment on, treatment off, treatment on again.
They tracked walking speed, balance, and how well the arm worked in daily tasks.
What they found
All three people moved better after the Zoom sessions.
Walking, balance, and arm use scores went up during every treatment phase.
Gains dropped when sessions stopped and came back when Zoom started again.
How this fits with other research
Nicola et al. (2018) already showed you can trust Zoom scores on motor tests.
Jeong’s study now proves you can also teach big-amplitude moves through that same screen.
Schieltz et al. (2020) said telehealth works for coaching families; Jeong adds that the patient can stay home and still gain real motor skills.
Shih et al. (2012) used Wii boards to boost walking via fun feedback.
Jeong swaps the Wii game for LSVT-BIG drills but keeps the same ABAB proof that tech drives real movement change.
Why it matters
You can now offer LSVT-BIG to stroke survivors who can’t drive to clinic.
No special gear is needed—just a laptop and a 6-foot space.
Add a quick Zoom tech check, cue “big” moves, and watch gait and balance rise in four weeks.

03Original abstract
This study is aimed at determining the effects of telerehabilitation‐delivered LSVT‐BIG on physical function, occupational performance, and activities of daily living in patients with stroke. The participants included three patients who had been diagnosed with stroke for > 6 months. This study used the ABA single‐subject study design. The study process was conducted for a total of 24 sessions over 6 weeks, including four sessions of baseline (A), 16 sessions of intervention using ZOOM (B), and four sessions of re‐baseline (A ′). During the intervention period (B), the intervention was conducted four times a week for 4 weeks for 60 min each time, according to the standardized LSVT‐BIG protocol. Repeated measures assessments included the Timed Up and Go (TUG) and the Box and Block Test (BBT) at each session. The Canadian Occupational Performance Measure (COPM), modified Barthel index (MBI), and Fugl‐Meyer assessment (FMA) were used to assess changes before and after the intervention. Descriptive statistics and visual analyses were used for data analysis. After the telerehabilitation‐delivered LSVT‐BIG intervention, all participants showed improvement in physical function. The TUG performance time decreased in each session, and the gait and balance improved. Both the BBT and FMA‐affected side scores of both upper limbs increased compared with those before the intervention, indicating improvement in upper limb function. In terms of occupational performance and activities of daily living, the COPM performance and satisfaction scores and the MBI scores both increased after the intervention. The positive clinical applicability of telerehabilitation‐delivered LSVT‐BIG intervention for patients with stroke was confirmed. In the future, follow‐up studies on LSVT‐BIG intervention that expand the benefits of telerehabilitation are needed.
