Investigation of the Efficacy of Balance Training Program Applied With Stroboscopic Glasses in Female Volleyball Players With Chronic Ankle Instability

Participants in Group A completed a supervised, multi-modal balance training program while wearing Senaptec stroboscopic glasses (Beaverton, Oregon), set to a duty cycle of 100 ms transparent followed by 150 ms opaque. The glasses use liquid crystal lenses that alternate between clear and nearly opaque states when electrically activated and can operate in both binocular and monocular modes, with settings adjustable via a Bluetooth application. The program, targeting static and dynamic balance in individuals with chronic ankle instability, consisted of six progressively challenging exercises performed indoors, barefoot, in small groups, lasting approximately 20 minutes per session, twice weekly for eight weeks. Exercises were completed in two sets with 30-second rests between exercises and 2-minute rests between sets, and progression was adjusted based on participant performance.

The intervention consisted of a supervised, multi-modal balance training program targeting differentaspects of static and dynamic balance for participants with chronic ankle instability. The program included six progressively challenging exercises, administered under the supervision of a physiotherapist. Each session lasted approximately 20 minutes, and participants completed two sessions per week for eight weeks. The training was conducted indoors, barefoot, in small groups, with exercises performed in two sets, including 30-second rests between exercises and 2-minute rests between sets. Progression was implemented according to participants' performance throughout the program.
