Effect of balance training with and without stroboscopic vision on kinesiophobia, proprioception and timing of muscle activity of selected muscles in people with chronic ankle instability

Comparing the effect of balance training with and without stroboscopic vision on kinesiophobia, proprioception, and timing of muscle activity of selected muscles in people with chronic ankle instability

A randomized clinical trial study, single-blind, parallel-group, 45 elderly randomized to 3 intervention groups and a control group through web-based randomization

After evaluation by a physician, and inclusion-exclusion criteria, the researcher records the personal information of patients among with the signed consent form. Participants are divided into two groups intervention and control groups. This study was single-blind and the outcome assessor is blind to interventions and groups. This study will be conducted in the laboratory of movement analysis, faculty of physical education at Kharazmi University. The protocols are 8 weeks and three 60-minute sessions per week

Inclusion criteria: A score of less than 27 on the Cumberland Ankle Functional Instability Test, A history of at least two acute sprains in the last 6 months, Exclusion criteria: History of any ankle fracture, History of ankle joint surgery, Acute ankle sprain in the last 6 weeks, Vestibular or balance dysfunction

Intervention group 1: includes balance exercises three sessions a week for 6 weeks. The duration of each session is 60 minutes and 10 minutes of warm-up and cooling-down program is considered for each session. Intervention group 2: balance exercises with stroboscopic glasses, three weekly sessions for 6 weeks. Each session lasts 60 minutes, and 10 minutes of warm-up and cool-down program is considered for each session. The control group, no exercise program only performs daily activities during this time.

Ankle Proprioception, Ankle Instability Electromyography of lower limb muscles, Kinesiophobia

Randomization will be done using simple randomization individually and random sequence allocation through a computer program aided by a web-based program (randomizer.org). It will be determined by a non-involved research team member when selecting samples from opaque, sequentially numbered sealed envelopes for allocation concealment. Participants will be allocated to two intervention groups and one control group.

In this study, the outcome assessor is blind to the groups’ randomization and interventions receiving by participants. in this way, during the evaluation before and after the intervention protocol, they do not make mistakes in their judgments in favor of a specific therapeutic intervention.
