Sensory-Targeted Ankle Rehabilitation Strategies (STARS)

The purpose of this study is to determine the effect of 3 types of sensory-targeted rehabilitation interventions on subjective and objective measures of function for those with chronic ankle instability. The investigators hypothesize that subjective and objective measures of function including self-reported disability, balance, and range of motion will improve after 2-weeks of sensory-targeted interventions.

About this study

The purpose of this study is to determine the effect of 3 types of sensory-targeted rehabilitation interventions on subjective and objective measures of function for those with chronic ankle instability. If a potential participant is deemed eligible for participation and consents to participate, he/she undergo a pretest session in which balance, gait, and range of motion will be assessed. The participant will then be randomized into one of the 4 treatment groups and undergo the first treatment which takes approximately 5 minutes. After completion of the first treatment, the participant will be immediately retested on the balance, gait, and range of motion measures. Upon completion of testing on the first day, participants in the treatment groups will be asked to return for 5 more treatments over the course of 2 weeks. Upon completion of the treatments, each participant will be tested on their balance, gait, and range of motion again. Then, after 1 month, each participant will be contacted to do a self-reported function follow-up visit in which he/she will be asked to report how stable and functional his/her ankle has been over the past month.

Treatment and study plan

Ankle Joint Mobilization

Other

The posterior ankle mobilization treatment is a manual therapy technique that consists of gently gliding your ankle in the backward direction through a pain free range of motion. This is a common therapy technique used by athletic trainers for the treatment of ankle sprains. The objective of this therapy technique is to glide the ankle into the area which restricts range of motion and gently stretch the restricted area. To begin this treatment, a certified athletic trainer with experience in applying this therapy technique will provide mild traction to the ankle joint to lightly distract the bones of the ankle joint. The athletic trainer will then apply two sets of joint mobilizations which will each last 2 minutes. Each repetition will consist of gently gliding the ankle joint in the backward direction until an area of restriction is reached. The athletic trainer will push into the restriction and then glide the ankle back to the starting position.

Other names: Ankle Range of Motion, Joint Manipulation

foot massage

Other

The foot massage treatment is a manual therapy technique that consists of gently rubbing the bottom of your feet with both hands like kneading dough. To begin the treatment, you will be asked to lie comfortably on a treatment table you're your feet hanging slightly off the edge. The athletic trainer with experience in applying this therapy will place his hands on the bottom of your foot and begin to massage your feet from your toes down to your heel. The athletic trainer will perform 2 sets of 2 minutes of massage with 1 minute rest in between sets.

Other names: Plantar Massage, Plantar Stimulation, Foot Rub

Calf Stretching

Other

The calf stretching treatment is a technique that is commonly used in sports and rehabilitation. You will be asked to place your foot on a slant board located next to a wall with your heel positioned below your toes on the slant board. You will be asked to lean towards the wall until you feel tension in your calf muscles that feels like a good stretch. You will perform 2 sets of 3 stretches that are held for 30 seconds each. Between each stretch, you will rest for 10 seconds. Between each set, you will rest for 1 minute.

Other names: Muscle Stretch, Flexibility

Primary outcomes

  1. Foot and Ankle Ability Measure

    Time frame: This will be assessed at 3 time points: Change from Pre-intervention to Post-Intervention, change from Pre-Intervention to 1-month Post-Intervention

    The Foot and Ankle Ability Measure (FAAM) is a questionnaire used to quantify the amount of self-reported disability a person experiences because of chronic ankle instability. It has two sections which will be used to assess disability associated with activities of daily living and sport activities.

  2. Gait Initiation

    Time frame: This will be assessed at 3 time points: Change from Pre-Intervention to Immediately Post Day 1 Intervention, and Change from Pre-Intervention to Post-Intervention

    Gait initiation is a laboratory technique that involves the use of a force plate. Participants are asked to stand on the force plate with feet and step off the force plate with either the right or left foot. The size of the weight shifts a participant makes while taking a step are evaluated using the force plate. Each participant will complete 5 trials stepping with each leg for every time point.

  3. Time to Boundary

    Time frame: This will be assessed at 3 time points: Change from Pre-Intervention to Immediately Post Day 1 Intervention, and Change from Pre-Intervention to Post-Intervention

    Time to Boundary is a balance measurement in which a person maintains single leg stance on a force plate for 10 seconds. This measurement technique evaluates the amount of time a person has to make corrections to maintain balance. Each participant will perform 12 trials for each time point. Each leg will be tested 6 times, 3 with eyes open and 3 with eyes closed.

  4. Weight-bearing Lunge Test

    Time frame: This will be assessed at 3 time points: Change from Pre-Intervention to Immediately Post Day 1 Intervention, and Change from Pre-Intervention to Post-Intervention

    The Weight-bearing Lunge Test is a measure of ankle dorsiflexion range of motion while the participant stands in front of a wall.

  5. Cutaneous Sensation

    Time frame: This will be assessed at 3 time points: Change from Pre-Intervention to Immediately Post Day 1 Intervention, and Change from Pre-Intervention to Post-Intervention

    Each participant will have the sensitivity of the bottom of his/her feet assessed. The investigators will use a set of monofilaments (similar to fishing line) to see how small of a monofilament can be detected when the investigator touches the bottom of his or her foot. Participants will be asked to close their eyes during testing.

  6. Single Limb Balance Error Scoring System Assessment

    Time frame: This will be assessed at 3 time points: Change from Pre-Intervention to Immediately Post Day 1 Intervention, and Change from Pre-Intervention to Post-Intervention

    Each participant will be asked to balance on one leg for 20 seconds with eyes closed while standing on the floor. During the test, the investigator will count how many times the participant deviates from the target position (standing on one leg with hands on hips).
