Background: Previous studies have suggested that the Pro-Kin visual feedback balance system can promote the recovery of balance function in stroke patients. Objectives: However, this system has not been used effectively in the early stages of stroke rehabilitation. This study aimed to investigate the effect of Pro-Kin system combined with weight loss system for the early recovery of balance and walking ability following a stroke. Methods: A total of 62 patients who underwent radiological diagnosis of stroke were randomly divided into two groups: a control group (n = 31) and a treatment group (n = 31). Both groups received conventional balance training. The treatment group also received training on the Pro-Kin system in conjunction with a weight loss system. Balance was measured using the Berg Balance Scale (BBS), Timed 'Up & Go' (TUG) test and Pro-Kin system. Walking ability was assessed using the Functional Ambulation Classification (FAC). The tests were performed before the start of treatment and on the 4th week following the training. There was no statistically significant difference between the groups before training. Results: After 4 weeks of training in both groups, there were significant improvements in balance and walking ability. BBS values and FAC were significantly higher (p < 0.01), TUG times, ellipse area and motion trajectory length were significantly reduced (p < 0.01, p < 0.05) after training. The treatment group outperformed the control group (p < 0.05). In addition, there was a positive correlation between balance function and walking ability (p < 0.01). Conclusion: The Pro-Kin system combined with weight loss system is a viable method that promotes early reconstruction of balance and walking ability following a stroke.
