Abstract ▼ AI-Helper

Purpose: In chronic stroke patients, muscle tone and stiffness increase due to ankle spasticity. Electrotherapy may control the spasticity of patients with central nerve system damage via neurophysiological mechanisms. Therefore, this study was conducted to determine the immediate effects of interferential current therapy on gastrocnemius (GCM) muscle. Methods: This study was a one-group pretest-posttest design and 20 stroke patients participated. The experimental group underwent interferential current therapy for GCM for 30 minutes. Muscle tone (MT) and stiffness were assessed using MYOTONE(R) PRO. After 30 minutes of interferential current therapy, MT and stiffness of the affected side and unaffected side by GCM were measured. Results: After interferential current therapy, the medial GCM MT (Hz) was significantly reduced in stroke patients. There was a significant difference in MT between affected GCM muscles and unaffected side medial GCM muscles before intervention, but there was no significant difference after interferential current therapy. Conclusion: This study demonstrated that interferential current therapy had a positive effect, producing an immediate decrease in the medial GCM muscles tone of stroke patients. However, this study employed a one-group pretest-posttest design. Future studies will show differences in muscle tone compared to a control group or other electrical stimulation treatments.

문제 정의

This study was conducted to investigate the immediate effects of interferential current therapy on the GCM muscle tone and stiffness of stroke patients. A total of 20 stroke patients were recruited with a one-group pretest-posttest design.

제안 방법

Therefore, this study was conducted to investigate immediate changes in GCM tone and stiffness in stroke patients following ICT in both affected and unaffected legs and to propose a new electrotherapy treatment.

대상 데이터

Twenty patients with stroke from Y Rehabilitation Hospital, Gyeonggi-do, South Korea, were included in this study. The selection criteria were as follows: chronic stroke patients between 1 year or more and less than 3 years after onset, a Korean mini-mental state examination (K-MMSE) score of 24 or higher, a MAS score of 2 or higher of the affected GCM, and Brunnstrom stage 3 or higher[2].

데이터처리

General characteristics such as the average and standard deviation were evaluated using descriptive statistics. A paired-t test was used to compare the affected and unaffected sides before and after intervention. A p<.

성능/효과

After the subjects were treated with ICT, no significant changes in the lateral GCM MT (p>.05) were noted; however, a significant decrease in the medial GCM MT on the affected side was observed after the intervention (p<.05).
It should be noted that this study could not determine the effectiveness of ICT because the number of subjects included was small, only those with high MAS scores were selected, and there was no control group. However, our finding that ICT alone, without therapeutic exercise, decreased the medial GCM tone is clinically significant.
