The Effect of Capacitive and Resistive Electric Transfer Therapy in Chronic Ankle Instability Patients

Chronic Ankle Instability Clinical Trial

Official title: Effectiveness Study of Capacitive and Resistive Electric Transfer Therapy Combined With Balance Training on Chronic Ankle Instability

Status Completed

Clinical Trial Summary

The goal of this clinical trial is to compare the applicability and effectiveness of capacitive and resistive Electric transfer (CRET) therapy in combination with balance training in improving ankle function, proprioception, and balance in patients with chronic ankle instability (CAI). The main questions it aims to answer are:

• Can CRET therapy expedite the rehabilitation process for patients with chronic ankle instability?

• Does the combination of CRET therapy and balance training yield superior efficacy to other interventions?

This study involved 31 physically active participants with unilateral ankle instability, comprising 19 males and 12 females. The participants were randomly assigned to one of three groups: the balance training group (B Group), the capacitive and resistive electric transfer group (CRET Group), and the balance training combined with the capacitive and resistive electric transfer group (B+CRET Group).

Clinical Trial Description

B group received only the balance training program, CRET group received only the CRET therapy, and B+CRET group received both the balance training program and the CRET therapy. Each intervention group received 12 interventions, three times per week, for a total of four weeks. Participants were instructed not to participate in any other exercise or treatment program during the experiment. Measurements were taken by the same researcher before and after the intervention. All participants were fully informed of the experiment's purpose and procedures and provided voluntary informed consent to participate. 31 participants completed the experimental study three times per week for four weeks under the guidance of a physical therapist. Only data from individuals with a completion rate of 75% or higher were included in the analysis.

The technical line of this study was to collect basic information about the participants, including age, height, weight, injury history, etc., and perform Ankle Special Tests, One Leg Standing Test, modified Star Excursion Balance Test, and fill out the Ankle Joint Functional Assessment Tool. Then the intervention groups underwent 12 sessions. In both the CRET and B+CRET groups, participants received a 10-minute intervention in CAP mode followed by a 20-minute intervention in RES mode. However, the B+CRET group received balance training along with CRET treatment.

The data was processed and analysed using SPSS 29.0 and Excel before and after the experiment. For count data that conformed to a normal distribution, mean ± standard deviation was used to express them. One-way ANOVA was used to analyse pre- and post-intervention between-group differences, with two-way comparisons using Tukey's test. Paired-sample t-tests were used to analyse pre- and post-intervention within-group differences. The Kruskal-Wallis H test was used to analyse pre- and post-intervention between-group differences for data that did not conform to a normal distribution. Similarly, the Wilcoxon signed-rank test was used to analyse pre- and post-intervention within-group differences. A significant difference was indicated by P<0.05 for all statistical results. ;
