PURPOSE: This study aimed to investigate the effects of pressure sense perception training (PSPT) on various surfaces on the somatosensory system, balance, and walking ability in chronic stroke patients. METHODS: Thirty patients with stroke participated in this study and were randomly assigned to one of three groups; group 1 received the general physical therapy and the PSPT on a stable surface, group 2 received the general physical therapy and the PSPT on an unstable surface, and group 3 received the general physical therapy alone. Participants in group 1 and group 2 underwent 30 min/session, 3 days per week, for 4 weeks. Pressure error (PE) was used to evaluate changes of proprioception. The Balancia, Functional reach test (FRT), and Timed Up and Go (TUG) were used to assess the balance ability, and the 10m Walking Test (10-MWT) was used to assess walking ability. RESULTS: Experimental groups (group 1 and group 2) showed significant differences in PE, FRT, TUG, and 10-MWT compared to the control group (p <0.05). Group 2 (PSPT on an unstable surface) was significantly different in PE, FRT, and 10-MWT from group 1 (p <0.05). No significant differences were observed for other measures. CONCLUSION: Pressure sense perception training on an unstable surface might be a significantly more effective method for improving somatosensory function, balance, and walking ability, than PSPT on a stable surface.

문제 정의
This study was a double-blinded, randomized controlled design. Participants were randomized into three groups (directly after the test) by a physical therapist not involved in the study.
This study was conducted in order to evaluate the effect of PSPT on an unstable surface in patients with chronic stroke. The results of PSPT improved somatosensory function, balance, and walking ability; with significantly better outcome in training on an unstable surface than a stable surface.

제안 방법
Participants were randomized into three groups (directly after the test) by a physical therapist not involved in the study. All of the enrolled patients were randomly assigned to 1 of 3 groups using a table of random numbers; group 1 received general physical therapy and the PSPT on a stable surface, group 2 received general physical therapy and the PSPT on an unstable surface, and group 3 received general physical therapy alone.
All subjects were patients with chronic stroke undergoing hospital rehabilitation, and independent standing maintenance. The analysis included thirty patients (20 men and 10 women) with no missing data on the outcome measure.
Subjects in the three groups participated in a rehabilitation program consisting of physiotherapy and occupational therapy during a 60-min session, 5 days per week, for 4 weeks. In addition, the experimental group (group 1 on the stable surface and group 2 on the unstable surface (balance pad) participated in the PSPT described below.
05) in the pre-test (Table 2). The study was conducted 30 min/day, 3 days a week, for 4 weeks. All procedures are shown in the flow diagram (Fig.
Second, absence of follow-up after the end of intervention did not allow for determination of the durability of effects. Therefore, conduct of further studies, including large sample sizes and long-term follow-up assessment are required in order to evaluate the effects of PSPT.

The Kruskal-Wallis test or a 1-way analysis of variance was used to assess the homogeneity between groups before the study. Because outcome measurement data showed parametric distributions, the paired t-test was used to compare data obtained before and after treatment in each group. The 1-way analysis of variance was followed by a Scheffe post-hoc test for comparison of significant differences among groups.

Table 1 outlines the baseline characteristics of the participants. The inclusion criteria were: (1) experienced a unilateral stroke at least 6 months post event or more, (2) able to maintain a standing position on the balance mat over 30 seconds, (3) capable of standing without any assistance over 30 seconds, (4) not training in any interventions from other institutions, and (5) sufficient cognition to participate in the training, that is, a Mini-Mental State Exam (MMSE) score of 24 or higher (Park and Kwon, 1989), (6) Semmes-Weinstein monofilaments test, size up to 5.07 discrimination of the foot pressure.

In this study, Experimental groups (group 1 and group 2) trained for the weight shift task on a stable or unstable surface. The result of this study seems to indicate improved balance ability. Furthermore, during weight shifting training, the therapist discussed with participants the degree of pressure, using feedback that might affect their weight shifting ability.
This study was conducted in order to evaluate the effect of PSPT on an unstable surface in patients with chronic stroke. The results of PSPT improved somatosensory function, balance, and walking ability; with significantly better outcome in training on an unstable surface than a stable surface. Thus, PSPT was successfully applied for clinical rehabilitation.
The results of this study showed a better improvement in the PSPT groups on the PE, balance, and walking ability than the control group. PE was used as a somatosensory test.
PSPT is a special program aimed at motor control through sensory input to improve balance. The study revealed that experimental groups (group 1 and group 2) showed significant differences in the pressure error (PE), Balancia (path-length, velocity average), FRT, TUG, and 10-MWT, compared to the control group after intervention. Group 2 (unstable surface) showed a significant difference from group 1 (stable surface) in PE, Balancia (velocity average), FRT, TUG, and 10-MWT.
