Summary

Pablo is a new virtual reality (VR) game combined with wearable motion sensor system which can targeted intervention in an interactive environment, immediate and sensitive feedback about the user's performance, a motivating effect due to game-based feature. Unlike commercial camera systems such as Kinect or force platforms, the systems require a continuous sightline or restrict the base of support which may increase risk of falling. Few of studies had investigated the rehabilitation effects on balance with Pablo for patients with stroke. The purpose of this study is to investigate the effects of virtual reality training through Pablo system in patients with chronic stroke.

Detailed description

Pablo is a new virtual reality (VR) game combined with wearable motion sensor system which can targeted intervention in an interactive environment, immediate and sensitive feedback about the user's performance, a motivating effect due to game-based feature. Unlike commercial camera systems such as Kinect or force platforms, the systems require a continuous sightline or restrict the base of support which may increase risk of falling. Few of studies had investigated the rehabilitation effects on balance with Pablo for patients with stroke. PURPOSE: The purpose of this study is to investigate the effects of virtual reality training through Pablo system in patients with chronic stroke. METHODS: A prospective, randomized, controlled, blinded assessor design was used. Patients with stroke were recruited and randomly assigned to a "virtual reality(VR) group" (n = 20) and "functional balance training (FBT) group" (n = 20). After 18 training sessions (60 minutes per session, 2 sessions per week), outcome measures which included the Berg Balance Scale, the Timed Up and Go Test (cognition), a gait analysis, the Activities-Specific Balance Confidence scale, Stroke Impact Scale (SIS), Level of pleasure, and frequency of adverse events. The data were analyzed using nonparametric tests, and significance was indicated at α \< 0.05.

Conditions

• Stroke

Interventions

Type	Name	Description
BEHAVIORAL	virtual reality treatment	18 virtual reality training through Pablo system (30 minutes a time, 2-3 times a week). Postural transition included sit-to-stand, sit down, reaching to different directions, stepping to different directions with weight transfer, and bending the trunk forward and side to side. The controller was attached to lower extremity or trunk to control the game, such as elevator, hot air balloon, shooting cans, etc.
BEHAVIORAL	standard treatment	18 standard rehabilitation sessions (60 minutes a time, 2-3 times a week). The rehabilitative protocol focus on strengthening, endurance training, ambulation, and ADL training that included: (1) Hip flexor and knee extensor strengthening with resistance progressing used by weight bag or Thera-band. (2) Cycle ergometer riding with increase speed and resistance. (3) Gait pattern and speed correcting through treadmill and parallel bar. (4) Hand functional training and strategy teaching for feeding, dressing, and toileting.
BEHAVIORAL	balance training	18 balance training sessions (30 minutes a time, 2-3 times a week) (1) Facilitated the balance reaction through weight shifting exercise with standing on even surface to uneven surface, such as tilting board.(2) Postural transition included sit-to-stand, sit down, reaching to different directions, stepping to different directions with weight transfer, and bending the trunk forward and side to side. (3) Changed the standing requirement, such as single legged stance or lunge stance. (4) Increased perception complications through cognition or upper extremity task to improve dual task attention.
