This was a single-blind randomized controlled trial of multisensory stimulation virtual reality to improve motor and cognitive dysfunction in stroke patients.
This was single-blind randomized controlled intervention study. Each stroke subject underwent screening period, baseline assessment period, intervention period, endpoint assessment period. The screening period include the verification of inclusion/exclusion criteria and the acquisition of informed consent. Baseline and endpoint assessment period include motor function related scales were evaluated (muscle strength, muscle tone, Fugl-Meyer scale, Berg balance scale); cognitive function related scale assessment \[Brief Mental State Examination Scale (MMSE), Montreal Cognitive Assessment (MoCA), drawing clock test, Shape connection test A.B, standardized digital modal experiment, auditory word Learning Test\], emotional correlation scale assessment (Hamilton Depression Scale, Hamilton Anxiety Scale), and activity of daily living scale ADL scale. Meanwhile, quantitative evaluation of motor function three-dimensional gait detection and assessment of brain functional activation (fNIRs tests and fMRI) were synchronously completed. The intervention period included multi-sensory stimulation immersive VR+ treadmill training with suitable for training intensity in the experimental group and only treadmill training similarly with suitable for training intensity in the control group. 20 minutes a day for 30 days, a total of 600 minutes (training frequency is adjusted according to the patient's own conditions). Preliminary validation of effectiveness assessment includes Fugl-Meyer scale, Berg balance scale, and three-dimensional gait detection. Preliminary validation of the safety assessment includes fall and dizzy incidents.

RECRUITINGFugl-Meyer Assessment- Lower Extremity
The Fugl-Meyer Assessment of Motor Recovery after Stroke - Lower Extremity (FMA-LE) evaluates lower extremity motor impairment through 17 items assessing reflexes, synergy patterns, and coordination. Each item is scored 0-2 (total range 0-34), with higher scores indicating better motor function. The total is the sum of all items, including motor (0-30) and coordination (0-4) subcomponents.

Functional Near-Infrared Spectroscopy Detection - Supplementary Motor Area - Oxygenated Hemoglobin (fNIRS Detection - SMA - HbO2)
Functional Near-Infrared Spectroscopy Detection - Supplementary Motor Area - Oxygenated Hemoglobin (fNIRS Detection - SMA - HbO2) measures cortical activation in the supplementary motor area via oxygenated hemoglobin concentration changes. Values are reported as changes from baseline in mmol/L, with increases indicating greater neural activity during motor tasks.

Berg balance scale
Berg Balance Scale (BBS) is a 14-item performance-based measure that assesses static and dynamic balance abilities in older adults or individuals with impaired balance function. Each item is rated on a 5-point ordinal scale ranging from 0 (unable to perform) to 4 (able to perform independently), yielding a total score range of 0 to 56, with higher scores indicating better balance and lower fall risk. The total score is calculated by summing all 14 individual item scores, and it is commonly used to evaluate balance impairment and predict fall risk in clinical populations.

3D Gait Analysis - Affected Side Step Width
3D Gait Analysis - Affected Side Step Width: This parameter measures the lateral distance between the two feet during walking, derived from three-dimensional motion analysis, focusing on the affected side. Units are centimeters (cm), with typical values ranging from approximately 5 to 20 cm depending on individual factors. Higher values represent wider step width, which may indicate balance deficits or compensatory strategies; lower values may also reflect instability. The clinical interpretation of better or worse outcomes is context-dependent.

Montreal Cognitive Assessment（MoCA）
Montreal Cognitive Assessment (MoCA) is a brief screening tool for mild cognitive impairment, evaluating visuospatial/executive function, naming, memory, attention, language, abstraction, delayed recall, and orientation. It comprises 30 items with a total score range of 0 to 30, where higher scores indicate better cognitive function (≥26 considered normal). The total is the sum of all subdomain scores.

Mini-Mental State Examination (MMSE)
Mini-Mental State Examination (MMSE) is a brief cognitive screening tool assessing orientation, registration, attention and calculation, recall, language, and visual construction. It consists of 30 items with a total score range of 0 to 30, where higher scores indicate better cognitive function (scores ≥24 are generally considered normal). The total score is calculated by summing all item scores.
