Novel Sock Design on Ankle and Postural Stability

Overview

This study uses a prospective cohort study design using a convenience sample to explore the sock's impact on various aspects of ankle function and overall stability. A secondary objective is measuring subjective changes in reported confidence levels in performing balance and stability exercises with and without sock

Study Design: This study uses a prospective cohort design to assess the effects of wearing the novel sock on ankle stability, muscle activation, and functional performance. Participant Consent: All participants will provide informed consent before beginning the study. They will be given the opportunity to ask questions about the procedures and consent will be documented by both the participant and the researcher. This process will take about 5 minutes. Participant Screening: Each participant will undergo screening based on the inclusion/exclusion criteria. They must be 18 years or older, with no recent ankle injury or surgery and no reported feelings of ankle instability or allergies to the sock material. A medical history questionnaire will be completed by each participant to confirm their eligibility. This process will take about 5 minutes. Warm-up and Familiarization: Participants will undergo the previously described warm-up, including 10 repetitions of specific exercises (toe spreads, toe raises, heel raises) and walking 120 meters to familiarize themselves with the sock. Warm-up will take 30 seconds for each exercise, and walking for familiarization will take about 1 minute. Functional Assessments: All assessments will be performed with and without the sock. The performance of the assessments with or without the socks will be randomized with each participant. Once randomized, all assessments will be performed and then the patient will either put on or take off the sock and perform the assessments again. Grip Strength: Grip strength will be measured using a hand dynamometer. Participants will sit in a chair with no armrests, feet flat on the floor, and squeeze the dynamometer with each hand while their forearm is positioned in a neutral position. Two trials will be conducted per hand, alternating hands with a 1-minute rest between each trial. The average of the two trials will be recorded. This assessment will take about 5 minutes. Single Leg Stance: This test measures static balance. Participants will be asked to stand on one leg, starting with the right leg. Timing will start when the participant lifts one foot off the ground and will stop when balance is lost or the foot touches the ground again. Each leg will be tested, and the average time from two trials will be recorded. This assessment will take about 5 minutes. Y-Balance Test (YBT): The YBT will be used to measure dynamic balance. Participants will stand on one leg and use the other leg to push a reach indicator in three different directions (anterior, posteromedial, and posterolateral). Six practice trials will be done, followed by three measured trials per leg. The distances reached will be recorded, and the average of the last three trials of each leg will be taken This assessment will take about 8 minutes. Functional Reach Standing: Participants will stand with their arm extended at 90 degrees and reach as far forward as possible without stepping. The distance reached will be measured and recorded using a yardstick. This test measures postural control and stability. This assessment will take about 2 minutes. Single Leg Hop: This test will measure dynamic balance and power. Participants will perform three types of hops: forward, lateral, and triple hops, landing on one leg. Each landing will be observed and assessed for balance. Participants will perform one practice attempt, then three trials for each test. The average of the three attempts will be recorded. The distance for each hop and any balance errors will be recorded. This assessment will take about 8 minutes. Balance Error Scoring System (BESS): Participants will perform balance stances (double leg, single leg, and tandem) on both a flat surface and foam pad for 20 seconds each. The researcher will record any balance errors such as eye opening or stepping off the testing surface. This assessment will take about 3 minutes. Fingertip to Floor Test (FFT) Participants will stand with their feet together on a 21.2 cm box and try to bend forward to reach as far down towards the floor as possible without bending their knees. Distance of fingertips from the ground will be recorded, if their fingertips touch the floor their radial styloid process will be used instead to measure the distance from the floor, using a ruler in centimeters. 1 practice trial will be conducted followed by 1 test trial. This test will take about 2 minutes to complete. After all tests have been performed with and without the novel sock, the participants will be asked to complete a google form questionnaire about their perceptions of their performance with and without the sock.
