Trial summary

Chronic Ankle Instability (CAI) is a health condition that results in repeated ankle sprains and other residual impairments. CAI has been linked to many different causative factors including sensory and motor deficits that affect the global function of the sensorimotor system as well as the patient.

About this study

Chronic Ankle Instability (CAI) is a health condition that results in repeated ankle sprains and other residual impairments. CAI has been linked to many different causative factors including sensory and motor deficits that affect the global function of the sensorimotor system as well as the patient. Over the past 20 years, strong evidence has been generated to support balance training as an effective intervention strategy in the CAI population. Unfortunately, most investigations have focused solely on maximizing motor output through balance training, while ignoring the full spectrum of sensorimotor dysfunction associated with CAI. There may be advantageous sensory-targeted interventions that augment the effects of balance training and lead to greater enhancements of functional outcomes for CAI. However, this possibility has not been systematically explored. Sensory-targeted ankle rehabilitation strategies (STARS), such as joint mobilization and plantar massage have resulted in improved sensorimotor function in those with CAI. However, only a single STARS (i.e. stochastic resonance) has been investigated in combination with balance training. While the combined effects were greater than those of balance training alone, stochastic resonance requires relatively expensive equipment that is not commercially available. Thus, the purpose of this investigation is to test the hypothesis that combining low cost STARS (e.g. plantar massage and joint mobilizations) with balance training will result in greater sensorimotor and functional improvements in those with CAI than balance training alone.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Balance TrainingBehavioural

    This is a 4-week supervised balance training program that has been previously validated in those with CAI by improving subjective and objective measures of function. During the 4-week program, subjects will complete three 20-25 minute sessions a week for a total of twelve supervised training sessions. The specific exercises and repetitions that will be performed per training session will include: 1) hop to stabilization (10 repetitions per direction), 2) hop to stabilization and reach (5 repetitions per direction), 3) unanticipated hop to stabilization (3 repetitions), 4) progressive single limb stance balance activities (3 repetitions), and 5) progressive single limb stance activities with eyes closed (3 repetitions).

  • STARSBehavioural

    The STARS intervention will consist of 4 unique sensory-targeted interventions: calf stretching, ankle joint traction, anterior/posterior ankle joint mobilizations, and plantar massage. These four techniques target 3 types of sensory pathways (musculotendinous, articular, and plantar cutaneous, respectively) and will be applied in the same order for all treatment sessions: 1) 60-second calf stretch, 2) 30-second ankle traction, 3) 30-second mobilization, 4) 2-minute plantar massage, 5) 30-second ankle traction, and 6) 30-second mobilization.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Balance

    Dynamic balance will be assessed with the Star Excursion Balance Test (SEBT). This test requires a person to maintain their balance on a single limb while reaching as far as they can (with their other leg) in 3 different directions (forward, back-left, and back-right).

    Measured: Balance at 1-day post intervention

  2. Self-assessed Disability

    2 questionnaires regarding self-assessed disability during activities of daily living and sport will be completed. The questionnaires will include the Foot and Ankle Ability Measure, and the Foot and Ankle Ability Measure-Sport. The FAAM contains 21 activity related items (max score of 84) while the FAAM-S contains 8 activity related items (max score of 32). Lower percentages (patient's score divided by max score) represent greater disability, and both FAAM and FAAM-S scores have been found to be reliable and precise (r=0.89, SEM= 2.1 and r=0.87, SEM= 4.5, respectively) in people with CAI.

    Measured: Disability to 1-day post intervention

Secondary outcomes (3)
  1. Balance

    Dynamic balance will be assessed with the Star Excursion Balance Test (SEBT). This test requires a person to maintain their balance on a single limb while reaching as far as they can (with their other leg) in 3 different directions (forward, back-left, and back-right).

    Measured: Change from baseline balance at 1-week post intervention

  2. Self-assessed Disability

    2 questionnaires regarding self-assessed disability during activities of daily living and sport will be completed. The questionnaires will include the Foot and Ankle Ability Measure, and the Foot and Ankle Ability Measure-Sport.

    Measured: Change from baseline disability at 1-week post intervention

  3. Self-assessed Disability

    3 questionnaires regarding self-assessed disability during activities of daily living and sport will be completed. The questionnaires will include the Ankle Instability Instrument, the Foot and Ankle Ability Measure, and the Foot and Ankle Ability Measure-Sport.

    Measured: Change from baseline disability at 1-month post intervention

Questions about this trial

What is this clinical trial studying?

A study testing Balance Training and STARS in people with Ankle (Ligaments); Instability (Old Injury), run by University of North Carolina, Charlotte at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Yes. Results are posted in the registry (first posted 24 Dec 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Balance (time frame: Balance at 1-day post intervention). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
