Researchers are evaluating the effects of a novel sock design on ankle and postural stability in adults. This study uses a prospective cohort design to explore how wearing the sock impacts ankle function, muscle activation, and overall stability. It also aims to measure changes in participants confidence when performing balance and stability exercises with and without the sock. Participants will perform a series of functional tests both while wearing the stability sock and without it. These assessments include grip strength, single leg stance, Y-Balance Test, functional reach, single leg hops, balance error scoring, and fingertip to floor tests. The order of testing with or without the sock will be randomized, and each test is timed or measured for performance and balance errors. During the study, participants will provide informed consent and complete a medical history questionnaire to confirm eligibility. They will undergo a warm-up routine before testing and complete all assessments twice, once with and once without the sock. After testing, participants will fill out a questionnaire about their perceptions of performance. The primary outcomes measured immediately after the intervention include grip strength, balance, dynamic stability, and postural control. The study is expected to continue until early 2026.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Stability Sock | Balance training / External supports |
|---|---|---|
| What it is | A novel device‑like sock designed to support ankle and postural stability by wearing it during functional tasks | Proprioceptive and neuromuscular training through rehabilitation exercises is a key management strategy |
| Role in study | Participants wear the stability sock during functional tasks to assess its immediate effect on ankle and postural performance | Not tested in this study but commonly used in current practice for improving ankle function |
| Primary use | To explore whether wearing the sock improves measures of ankle and postural stability immediately after intervention | To enhance balance and neuromuscular control over time in individuals with ankle instability |
| How it is used | Worn during sit‑to‑stand, jump, balance and hop tasks as defined in the trial protocol | Typically applied or performed in therapy sessions under clinician guidance or via self‑managed exercises |
| Evidence status | Effect on stability is under investigation; no results posted yet | Rehabilitation exercises and external ankle supports have evidence showing they improve postural stability in individuals with ankle instability |
| Important risks | No specific safety risks documented in trial registry | Generally low‑risk interventions; minor discomfort or skin irritation possible with external supports |
| Important limitations | Evidence limited to immediate effects in a single‑group feasibility study without comparison group | Effects depend on long‑term adherence and may vary by individual needs |
| Patient impact | Not yet established | Evidence supports improved balance, stability, and functional performance through rehabilitation and supports |
