NCT04493645

Brief Summary

The overall objective of this study is to examine the effects of a 6-week foot-intensive rehabilitation (FIRE) program on lateral ankle sprain (LAS) re-injury rates, CAI symptoms, sensorimotor function, and self-reported disability in CAI patients.

Outcome Measures

Primary Outcomes (3)

  • Number of recurrent ankle sprains

    The ability of FIRE to attenuate the occurrence of ankle sprains compared to SOC rehabilitation will be determined through self-report. An ankle sprain will be operationally defined as an incident in which the rearfoot was inverted or supinated and resulted in a combination of swelling, pain, and time lost or modification of normal function for at least one day.

    24 months

  • Frequency of episodes of the ankle giving way

    The ability of FIRE to attenuate the number of episodes of the ankle giving way compared to SOC rehabilitation will be determined through self-reported occurrences per week in the past month. Episodes of giving way will be operationally defined for the subject as an incident in which the rearfoot suddenly rolled, felt weak, or lost stability; however, the individual did not sustain an ankle sprain and was able to continue with normal function.

    24 months

  • Severity of chronic ankle instability related symptoms

    The ability of FIRE to attenuate the severity of related symptoms compared to SOC rehabilitation will be determined through the Cumberland Ankle Instability Tool. The Cumberland Ankle Instability Tool is a 9-item instrument used to identify self-reported impairments associated with CAI. This instrument is scored on a 0-30 scale, where lower scores represent greater severity of CAI related symptoms.

Study Arms (2)

Standard of Care (SOC)

ACTIVE COMPARATOR

Participants will be randomized to receive standard of care rehabilitation (SOC) for a period of 6 weeks.The investigators will prospectively follow participants assigned to the SOC group for 24 months following completion of their assigned SOC intervention.

Behavioral: Standard of Care Rehabilitation (SOC)

Foot Intensive Rehabilitation (FIRE)

EXPERIMENTAL

Participants will be randomized to receive foot intensive rehabilitation (FIRE) for a period of 6 weeks.The investigators will prospectively follow participants assigned to the FIRE group for 24 months following completion of their assigned SOC intervention.

Behavioral: Foot Intensive Rehabilitation (FIRE)

Interventions

6 weeks of standard of care rehabilitation will be given designed to restore ankle joint range of motion, strength, postural control, and functional movement. Each participant will be expected to complete 2 supervised sessions and 3 unsupervised at home sessions per week.

Standard of Care (SOC)

6 weeks of FIRE will be given along with elements of SOC. Each participant will be expected to complete 2 supervised sessions and 3 unsupervised at home sessions per week.

Eligibility Criteria

Age18 Years - 44 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Aged 18-44.
  • Previous history of at least 1 ankle sprain and at least 2 episodes of "giving way" in the past 3 months.
  • Participants must answer "yes" to at least 5 questions on the Ankle Instability Instrument.
  • Score of 11 or higher on the Identification of Functional Ankle Instability (IdFAI).
  • Confirmed clinical presentation of CAI by a PT, AT, or MD.

You may not qualify if:

  • Sustained an ankle sprain in the previous four weeks or lower extremity neuromusculoskeletal injury other than to the ankle in the last 12 months.
  • History of surgery to the lower extremity.
  • Sustained a lower extremity fracture.
  • History of neurological disease, vestibular or visual disturbance or any other pathology that would impair their sensorimotor performance.
  • Current participation in a formal ankle joint rehabilitation program.
  • Sustained a concussion in the last 12 months.
  • Exhibit clinical examination characteristics of foot and ankle function which are consistent with conditions other than CAI (i.e. fracture, deformity).

PARALLEL
Model Details: The investigators will compare clinical and innovative outcome measures collected at five time points between cohorts of patients with CAI that receive a standard of care (SOC) rehabilitation program compared to an innovative foot intensive rehabilitation (FIRE) program to determine if FIRE can further reduce the rate of re-injury, improve sensorimotor function, and reduce self-reported disability during the 24 months following the intervention.
