Effects of Two Compression Socks on Balance and Ankle Stability in Healthy Adults

This randomized study will compare a novel tensioning compression sock with a commercially available elastic foot and ankle compression sock in healthy adults. Participants will wear their assigned sock during waking hours for at least 6 hours per day for 7 days. Balance, ankle stability, grip strength, and tibialis anterior muscle contraction characteristics will be assessed at baseline and after the 7-day intervention. Participants will also report comfort and confidence in balance and stability after the intervention.

About this study

Participants will attend two in-person visits separated by 7 days. After consent, screening, and baseline testing, participants will be randomized using a computer-generated sequence concealed in sequentially numbered opaque envelopes. Participants will receive either the Trak Ground Wear C001 High-Performance Compression Sock or a commercially available elastic foot and ankle compression sock and will wear it for at least 6 hours per day during waking hours. Assessments include the Y-Balance Test, Side Hop Test, Biodex Balance System, handgrip dynamometry, and tensiomyography of the tibialis anterior. A post-intervention questionnaire will assess perceived comfort, balance confidence, stability, and willingness to wear the assigned sock.

Treatment and study plan

Novel Tensioning Compression Sock

Other

Participants assigned to the control group will receive a commercially available elastic foot and ankle compression sock. Participants will be instructed to wear their assigned sock during waking hours for a minimum of 6 hours per day over the 7-day intervention period.

Elastic Compression Sock

Other

Participants assigned to the control group will receive a commercially available elastic foot and ankle compression sock. Participants will be instructed to wear their assigned sock during waking hours for a minimum of 6 hours per day over the 7-day intervention period.

Primary outcomes

  1. Y-Balance Test

    Time frame: 7 days

    Mean Change From Baseline in Y-Balance Test Reach Distance at day 7 . Three recorded trials are completed in the anterior, posteromedial, and posterolateral directions on each limb and averaged.

Secondary outcomes

  1. Side Hop Test

    Time frame: 7 days

    Change From Baseline in Side Hop Test Score at day 7. Participants perform repeated single-leg side hops across lines 40 centimeters apart for 30 seconds; the highest of two trials is recorded.

  2. Biodex Balance System

    Time frame: 7 days

    Mean Change From Baseline in Biodex Athlete Single Leg Stability Score at day 7. Three 20-second trials are completed on each lower extremity.

  3. Grip Strength

    Time frame: 7 days

    Mean Change From Baseline in Handgrip Strength at Day 7. Two maximal contractions are performed with each hand; the highest value for each hand is recorded.

  4. Tensiomyography

    Time frame: 7 days

    Mean Change From Baseline in Tibialis Anterior Contraction Time at Day 7. Two tensiomyography measurements are obtained for each limb and averaged.

  5. Confidence Survey

    Time frame: 7 days

    Participant-Reported Comfort, Balance Confidence, Stability, and Willingness to Wear the Assigned Sock at Day 7.
