简要总结
Stroke frequently leads to long-term balance impairments, increased fall risk, and reduced independence in daily activities. In chronic stroke patients, deficits in sensory integration and postural control may persist despite conventional rehabilitation programs. Additional targeted balance interventions may enhance recovery by improving multisensory processing and motor control.
This study investigates whether adding biofeedback-based interactive posturographic balance training to conventional rehabilitation improves balance performance, fall risk, functional independence, and psychological well-being in individuals with chronic stroke. Participants were randomly assigned to receive either conventional rehabilitation alone or conventional rehabilitation combined with interactive balance training for eight weeks. Outcomes were assessed using validated clinical scales measuring balance, fall risk, daily functioning, and emotional status.
详细描述
Stroke is a major cause of long-term disability and frequently results in persistent impairments in postural control and balance. In individuals with chronic stroke, altered sensory integration and impaired motor coordination contribute to increased fall risk and reduced functional independence. Although conventional rehabilitation programs address strength, mobility, and functional training, balance deficits may remain due to insufficient multisensory challenge and limited task-specific feedback.
Biofeedback-based interactive posturographic systems provide real-time visual and sensory feedback during standing tasks and systematically challenge postural control under varying sensory conditions. Such interventions may enhance motor learning and promote adaptive sensory reweighting mechanisms by exposing individuals to controlled visual deprivation and head-position alterations.
This prospective, single-blind randomized controlled study was conducted in individuals with chronic stroke (>6 months post-event). Participants were randomly assigned to receive either conventional rehabilitation alone or conventional rehabilitation combined with interactive posturographic balance training. The intervention period lasted eight weeks, with sessions conducted five days per week.
The primary objective of the study was to determine whether adding biofeedback-based interactive posturographic balance training improves clinical balance performance. Secondary objectives included evaluating effects on fall risk, functional independence, and psychological status.

研究组 & 干预措施
Interactive Posturographic Balance Training + Conventional Rehabilitation
Participants received conventional rehabilitation (45 minutes per session, 5 sessions per week) combined with biofeedback-based interactive posturographic balance training (25 minutes per session) for 8 weeks. The balance training was conducted using a multisensory posturographic system providing real-time visual feedback under varying sensory conditions. The conventional rehabilitation program included neurophysiological facilitation techniques, range of motion exercises, strengthening exercises, postural control training, weight-shifting exercises, and gait training.

Conventional Rehabilitation
Participants received conventional rehabilitation only (45 minutes per session, 5 sessions per week) for 8 weeks. The program consisted of neurophysiological facilitation techniques, range of motion exercises, strengthening exercises, postural control training, weight-shifting exercises, and gait training.
