The researches that concerned with visual feedback training was often used for treatment on symmetrical weight-bearing training in stroke patients. Although there were many researches for the effects of visual feedback training in stroke, it was not identify that effects of visual feedback training in stroke following pure motor, sensory deficit and neglect.
The purpose of this study was to investigate the effects of visual feedback training on standing balance in stroke with neglect and/or sensory deficit.
Subjects were assigned to pure stroke group, sensory deficit group and neglect group. In all groups, assessed for standing balance(weight-bearing symmetry on quiet standing, maximal voluntary weight bearing on affected/unaffected, limit of stability and training time of program ), balance performance(short form of Berg balance scale) and measured the EMG on lower extremity muscle for lateral stability(gluteus medius, hip adductors, medial gastrocnemius, lateral gastrocnemius and peroneal muscles) before training.
Subjects underwent the visual feedback training for three times per week and tested the standing balance once in two weeks during 10weeks. After training, retested the standing balance, balance performance and EMG.
The results of this study were as follows:
1. In all groups, there were statistically significant improvement in weight bearing on quiet standing, maximal voluntary weight shifting volume on unaffected side and totally, and program training times following visual feedback training during 10 weeks.
2. There were a statistically significant difference between groups in weight bearing on quiet standing, maximal voluntary weight shifting volume on affected side, maximal voluntary weight shifting volume on both side totally, and program training times following visual feedback training during 10 weeks.
3. There were statistically significant correlations among the affected side maximal voluntary limit of stability and weight bearing at least during 6weeks following visual feedback training in all groups, and sensory deficit and neglect group were statistically significant correlations during 10weeks.
4. In all groups, there were no significant correlations among the unaffected side maximal voluntary limit of stability and weight bearing during 10weeks.
5. In pure motor and sensory deficit groups, there were statistically significant improvement between pre and post training in SFBBS scores following visual feedback training.
6. In all groups, there were statistically significant improvement between pre and post training in muscle activation of affected side gluteus medius, medial and lateral gastrocnemius and peroneal muscles when weight transfer on affected side.
7. In all groups, there were statistically significant improvement between pre and post training in muscle activation of unaffected side lateral gastrocnemius and peroneal muscles when weight transfer on unaffected side.
In conclusion, although pure motor stroke group was more improve than neglect and/or sensory deficit groups through the visual feedback training, neglect and/or sensory deficit groups also could effect improvement. Therefore, visual feedback training was worth stroke whose included neglect and/or sensory deficit while to improve standing balance.
