About

In this study, the effects of different treatment methods for ankle instability patients are being compared aiming to find the optimal treatment. Via comparing virtual reality, motor imagery, and classic rehabilitation programs to clarify their effects on ankle static and dynamic balance, proprioception, range of motion, muscle strength, pain, function and patient satisfaction.

Full description

This study will be carried out at Istanbul University-Cerrahpaşa Department of Physiotherapy and Rehabilitation with 30 participants. Subjects who meet the inclusion criteria and who voluntarily agree to participate in this study will be randomly divided into 3 study groups as conventional physiotherapy rehabilitation treatment program, Conventional + virtual reality (VR) group and Conventional + VR+ motor imagery (MI) group. Group 1 (Conventional physiotherapy program): Physiotherapy and rehabilitation treatment program will be applied to the patients. In this program, a 30-40-minute exercise protocol covering proprioceptive, balance and strengthening exercises will be implemented. Group 2; VR group: in addition to the conventional physiotherapy program virtual reality (VR) program will be applied to this group using balance and strengthening games by Nintendo Wii Fit Plus; warm-up exercise (5 minutes), workout (20 minutes) and cool-down exercise (5 minutes) for a total of 30 minutes. Group 3; Motor imagery (MI): this group will be introduced to explicit Motor imagery program adding to Conventional physiotherapy and VR programs. The content of the imagery program will last 20 minutes in total, with 5 minutes of relaxation and 15 minutes of imagery training.

All patients in the groups will be treated for a total of 12 sessions, 3 days a week, over a 4-week period. Session duration will vary according to the groups. Interventions will last approximately 40-80 minutes.

Ankle mobility and instability will be assessed through different tests. Balance parameters will be measured with the Star Balance Test for dynamic balance and the Single Leg Stance Test for static balance. The pain intensity will be measured with the Pressure Pain Threshold device also with Visual Analog Scale. Muscle strength will be assessed with a manual muscle test. Ankle range of motion and joint position feeling will be measured with a mobile application such as an inclinometer. Finally, 2 questionnaires will be used to assess functional ability and patient satisfaction. These are; Cumberland ankle instability tool and Global Assessment Scale questionnaire respectively. All of the assessment parameters (outcomes measurement) will be evaluated twice, pre-treatment and post-treatment (after 4 weeks).Which approximately will take from 30 to 45 minutes.

G*Power analysis program was used to calculate the sample size of the study. While the Cumberland ankle instability tool (CAIT) change results were taken as reference, the effect size was calculated as 1.35, and the number of subjects to be included in the study was reported as a total of 15 patients (Group 1: 5/Group 2: 5/Group 3: 5) in order to be determined as significant with 95% power and type 1 error=0.05,however, the exclusion rate was added as 25% and it has been decided to include a total of 30 patients (Group 1: 10/Group 2: 10/Group 3: 10) (1). SPSS (Statistical Package for Social Sciences) (SPSS 20.0) statistical program will be used for statistical analysis of the data obtained. In all analyzes, p<0.05 will be considered statistically significant. Before the final analysis, the data will be screened to test the normality assumption using the Shapiro-Wilk test, which reflects normal distribution (p > 0.05). Furthermore, Levene's test was used to test homogeneity of variance and no significant difference was found (p > 0.05). If the data are normally distributed, parametric analysis (e.g. t-Test, ANOVA, Paired t-Test and Linear Regression) will be used, otherwise non-parametric analysis (e.g. Mann-Whitney U Test, Wilcoxon Signed-Rank Test, Kruskal-Wallis Test and Spearman's Rank Correlation) will be used.

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 39 years old

Volunteers: No Healthy Volunteers

• Patients with sub-acute (10 days after injury) and chronic ankle instability
• Diseases/patients without surgical indication
• Cases between the ages of 18-39
• Gender (Male-Female)

Exclusion criteria

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

30 participants in 3 patient groups

Conventional physiotherapy program group

Active Comparator group

Description:

Physiotherapy and rehabilitation treatment program will be applied to the patients. In this program, a 30-40-minute exercise protocol including proprioceptive, balance and strengthening exercises will be applied.

Treatment:

Other: Conventional physiotherapy program

Virtual reality (VR) program group

Active Comparator group

Description:

Virtual reality (VR) program will be applied in addition to the conventional physiotherapy program. In VR; the subjects will be asked to stand on the Wii fit balance board and will be able to physically and visually see and participate in the game. Nintendo Wii Fit Plus will last 30 minutes in total as warm-up exercise (5 minutes), workout (20 minutes) and cool-down exercise (5 minutes). Interactive video games will be used, including both strength and balance exercises. The exercises in the study include 5 muscle strengthening (e.g. forward lunge/ lunge, single leg extension, side leg raise, single leg bend, rowing) and 5 balance exercises (e.g. playing soccer, ski slalom, tightrope walk, snowboard slalom) among the programs built into the Nintendo Wii Fit Plus.

Treatment:

Other: Virtual reality (VR)

Other: Conventional physiotherapy program

Motor imagery (MI) program group

Active Comparator group

Description:

In addition to VR and conventional physiotherapy programs motor imagery program will be given to the patients in this group. Using the explicit MI method, individuals will be explicitly instructed to perform imagery (2). The physiotherapist will ask the patient to imagine a real or fantasy place that is peaceful, happy and relaxing. Then, they will be asked to imagine that they are in this picture. Patients will be asked to imagine themselves doing physiotherapy exercises and feel the movements as vividly as possible. The content of the imagery program will last 20 minutes in total, with 5 minutes of relaxation and 15 minutes of imagery training.
