Exploratory Trial of VR Intervention on Neuroplasticity in Older Adults With Cognitive Frailty

Condition(s) studied

Investigational drug(s) / intervention(s)

VR-Based Resistance Training Intervention: Participants in the intervention group will engage with a self-developed VR resistance training program entitled "Kitten Crossing the Bridge." This program is designed to guide older adults through static lower-limb resistance exercises, while integrating rhythm control, spatial judgment, and visual feedback. The intervention will be administered over 4 weeks, with two sessions per week; each session will last approximately 20 minutes (excluding equipment setup and rest periods). All training sessions will be supervised by qualified staff to ensure participant safety and provide necessary support.

Standardized Leg-Raising Training: Participants in the control group will implement a standardized leg-raising exercise protocol, which is designed to match the intensity and rhythm of the VR-based intervention. Training will be guided by pre-recorded verbal prompts and demonstration videos developed by the research team, ensuring procedural uniformity. Each session will last approximately 20 minutes (excluding equipment setup and rest periods), with two sessions per week over a 4-week duration. All sessions will be supervised by trained staff, who will monitor participant adherence and ensure safety throughout the process.

Study summary

To investigate the effects of VR based intervention on neuroplasticity in older adults with cognitive frailty.

Eligibility

Primary outcome measure(s)

• fNIRS — Baseline, 2 Weeks, 4 Weeks
  Neural activity during the intervention tasks will be recorded using a functional near-infrared spectroscopy (fNIRS) imaging system. A 24-channel NirLight fNIRS device (Huairui Medical Technology Co., Ltd., China) will be employed, with light sources operating at wavelengths of 760-850 nm and a sampling rate of 10 Hz. The probe configuration will primarily cover the frontal, parietal, and parts of the temporal and occipital lobes.
