Objective
To investigate the dose-related effect of trunk control training (TCT) using Trunk Stability Rehabilitation Robot Balance Trainer (TSRRBT) in chronic stroke patients with poor sitting balance.
Methods
This was a retrospective study of 38 chronic stroke patients with poor sitting balance that underwent TCT with TSRRBT. The participants were assigned either to the low-dose training (LDT) group (n=18) or to the highdose training (HDT) group (n=20). In addition to the conventional rehabilitation therapy, the LDT group received 5 sessions of TSRRBT intervention per week, whereas the HDT group received 10 sessions of TSRRBT intervention per week. The outcome measures were the scores on the Trunk Impairment Scale (TIS) and its subscales, Berg Balance Scale (BBS), Functional Ambulation Classification (FAC), and the Korean version of Modified Barthel Index (K-MBI). All outcome measures were assessed before the training and at the end of the 4-week training.
Results
After the 4-week intervention, TIS, BBS, FAC, and K-MBI scores showed improvement in both LDT and HDT groups. Furthermore, the improvements in TIS scores and its subscales were significantly greater in the HDT group than in the LDT group (p<0.05).
Conclusion
TCT using TSRRBT could be an additional treatment for the conventional rehabilitation therapy of chronic stroke patients with poor sitting balance. HDT may provide more beneficial effects on improving patients’ sitting balance than LDT.

Objective
This study was aimed to compare the effect of visuo-perceptual biofeedback sitting balance training using Balance Master in stroke patients with that of conventional sitting balance training.

Method: The subjects were twenty-four stroke patients receiving rehabilitation therapy who could maintain sitting posture independently. These patients were randomly divided into a control and an experimental group. The ability of static postural balance control with the modified Clinical Test Sensory Interaction Balance (mCTSIB) and the weight bearing test was measured before and after the balance training. The ability of dynamic postural balance control was measured with the limit of stability (LOS) test and the rhythmic weight shift test. Motor assessment scale (MAS) and modified Barthel index (MBI) were also checked for measuring the effects.

Results: There was significant improvement in both abilities of static and dynamic postural balance control in the experimental group that had visuo-perceptual biofeedback training using the Balance Master (p＜0.05). MAS and MBI scores after the training showed a bigger increase in the experimental group than in the control group.

Conclusion: The visuo-perceptual biofeedback sitting balance training using the Balance Master was considered to be more effective than the conventional training in the stroke patients. (J Korean Acad Rehab Med 2003; 27: 164-172)
