A vast majority (75-85%) of ankle sprain patients treated in emergency departments (ED) receive pain medication and are not referred for physical rehabilitation. Therefore, purpose of this study is to increase access to the standard of care for an ankle sprain by provide patients with physical rehabilitation delivered through telehealth. The purpose of this study includes compare a 2-week telehealth intervention to the usual care for treating 1) subjective function; 2) physical impairments; 3) medication consumption; and 4) patient-perceived barriers. The central hypothesis is participants receiving the 2-week telehealth intervention will 1) have less pain and disability; 2) improve balance and ankle range of motion; 3) consume less medication; and 4) reports positive feedback compared to the usual care group.
Musculoskeletal injuries account for 15% of all emergency department (ED) visits in the United States. More than 1 million people are treated in the ED every year for an ankle sprain; making it the most common musculoskeletal injury. Most ankle sprain patients do not receive the recommended care because the vast majority (75-85%) are prescribed opioid or non-opioid medication and are not referred for follow-up health care services. Physical rehabilitation is the gold standard for follow-up care because of its known benefits as a non- pharmacological alternative to pain management and for restoring normal function. However, ankle sprain patients aren't referred to physical rehabilitation because of the lack of access to timely health care services, particularly for rural communities or underserved urban areas. A lack of access and/or increased wait time from referral to the first outpatient visit has been associated with detrimental physical and psychological effects. In fact, without physical therapy, ankle sprain patients can develop chronic pain, become less physically active, report having a worse health-related quality of life, suffer a recurrent injury and show early symptoms of post- traumatic osteoarthritis. Telehealth is a novel method of care delivery designed to bridge this gap by leveraging live-video communication platforms to provide timely health care services. Therefore, the rationale for this project is demonstrating the benefits of telehealth to deliver the standard of care for an ankle sprain will lead to new methods providing timely access to follow-up health care services for patients discharged from the ED for not only an ankle sprain, but a wide variety of musculoskeletal injuries. The specific aims for the proposed research include comparing a 2-week telehealth intervention to the usual care for 1) treating pain, disability, health-related quality of life, and physical activity; 2) ankle range of motion, static and dynamic balance; 3) opioid and non-opioid medication consumption; and 4) the feasibility, acceptability and appropriateness of each intervention. The investigators hypothesize, compared to the usual care, participants receiving telehealth will 1) have less pain and disability; 2) a better health-related quality; 3) increased physical activity levels; 4) greater ankle range of motion; 5) better static and dynamic balance; 5) take fewer opioid and non-opioid medication; and 5) report positive feedback. A single-blind, randomized control trial will assign 70 ankle sprain patients discharged from the ED to two equal groups (Telehealth, usual-care). The telehealth intervention includes 5-live video sessions with an investigator providing education about injury management, long-term health and therapeutic exercises. The usual care group will follow their physicians' orders. The expected outcomes will illustrate the value of immediate access to rehabilitative services delivered via telehealth for an ankle sprain.

The first live-video session will orient participants to the features of the software, discuss the checklist to minimize environmental distractions, gauge how participants are managing their symptoms (pain, swelling) and provide non-pharmacological alternatives to supplement their current treatment strategies. The second live-video session will be used re-examine how the participant is managing their symptoms (pain, swelling) and re-emphasize non-pharmacological alternatives. The remaining live-video sessions will be focused on giving participants home-based therapeutic exercises. The therapeutic exercises will target the four main areas important to ankle sprain recovery: 1) range of motion; 2) balance; 3) gait; and 4) strength. All of the therapeutic exercises are based on previously published criteria for the rehabilitation of an LAS. The progression will start with single-plane, non-weight bearing or low-force activities and will advance at the same rate.
The usual care group will be instructed to follow their treating physicians' orders. Participants will not receive instructions on how to self-manage symptoms nor a home-based exercise program.

Change in Visual Analog Scale
Self-reported levels of acute ankle pain at rest, while walking, climbing stairs and when running will be recorded using separate 100 mm VAS for each of those tasks. Each VAS will be anchored on the left (0 mm) with 'no pain' and 'worst pain' on the right (100 mm). Participants will place a single handwritten mark at one point along the 100 mm line. The linear distance from the left end of the line to the participants' mark will be measured using a standard ruler and recorded in millimeters. Therefore, a higher numerical value reflects greater levels of pain intensity during the selected activity. Excellent test-retest reliability has been reported for assessing acute pain using a VAS (ICC=0.97).
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
Change in Foot and Ankle Ability Measure (FAAM)
The FAAM is a region-specific patient-reported outcome to measure self-reported function in patients with ankle pathologies. The FAAM contains items that measure the level of difficulty patients have performing activities of daily living (ADL) and physical activity (Sport). Items are scored on a 5-point Likert scale with 4 representing 'no difficulty' and 0 indicating 'unable to do'. The sum from both subscales is calculated and presented as a percentage of the total possible points. A lower score is indicative of decreased function and HRQL. The FAAM is reliable (ADL: ICC=0.89; Sport: ICC=0.087), valid and responsive to change after intervention.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
Documentation of opioid and non-opioid medication consumed:
Participants ≥18 years of age and legal guardians of adolescents will be given a daily log to record the type and dose of any opioid or non-opioid medication consumed. Frequent reminders to complete the daily medication log will be sent via email to both groups and the daily log will be collected at the end of each week. Secondly, all participants or legal guardian's will be interviewed weekly over the phone with and asked if they had filled their opioid prescription, the quantity of any medication consumed, and any new opioid prescriptions filled. Information gathered will be used to calculate the morphine milligram equivalent (MME) per day for any opioid medication. The MME per day consumed from baseline to post- intervention and post-intervention to the 1-month follow-up will be summed and used for statistical analysis. The number of tablets consumed per day for all non-opioid medication will be recorded, summed and used for statistical analysis.
Time frame: Total amount consumed between baseline to 24-72 hours immediately post intervention AND total amount consumed between immediately post intervention to 1 month folllow-up.
Change in Feasibility of Intervention Measure (FIM):
Feasibility is the extent to which a new treatment can be successfully used or implemented within a setting. The FIM contains four, 5-point Likert scales that assess the perceived feasibility of the intervention. Each Likert Scale is anchored with a 1 representing 'completely disagree' and 5 indicating 'completely agree'. The average score is calculated, with a higher score suggesting the intervention is perceived as being more feasible. The FIM has demonstrated acceptable internal consistency with a Cronbach α score of 0.89 and good test-retest reliability (r=0.88).
Time frame: Change from 24-72 hours immediately post intervention at 1 month follow-up.
Acceptability of Intervention Measure (AIM)
Acceptability is the extent to which stakeholders perceive a treatment to be palatable or satisfactory. The AIM includes four, 5-point Likert scales that assess the perceived acceptability of the intervention. Each Likert Scale is anchored with a 1 representing 'completely disagree' and 5 indicating 'completely agree'. The average score is calculated, with a higher score suggesting the intervention is perceived as being more acceptable. The AIM has shown acceptable internal consistency with a Cronbach α score of 0.85 and good test-retest reliability (r=0.80).
Time frame: Post-intervention and 1-month follow-up
Intervention Appropriateness Measure (IAM)
Appropriateness is the perceived fit, relevance and compatibility of the intervention to address a particular issue. The IAM includes four, 5- point Likert scales that assess the perceived appropriateness of the intervention. Each Likert Scale is anchored with a 1 representing 'completely disagree' and 5 indicating 'completely agree'. The average score is calculated, with a higher score suggesting the intervention is perceived as more appropriate. IAM has exhibited acceptable internal consistency with a Cronbach α score of 0.91 and good test-retest reliability (r=0.73).
Time frame: Change from 24-72 hours immediately post intervention at 1 month follow-up.
Disablement in the Physical Active Scale (DPA).
The DPA is a 16-item global outcome instrument. Responses to each item are based on a 5-point Likert scale ranging from 'no problem' to 'severe'. (26) High test-retest reliability (ICC = 0.943) and internal consistent (alpha = 0.890-0.908) have been reported.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
International Physical Activity Questionnaire (IPAQ)- Short Form
The IPAQ is regularly administered to quantify the kinds of physical activity that people do as part of their everyday lives. The IPAQ has been shown to be a reliable and valid measure of physical activity among all age categories.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
Weight-bearing lunge test (WBLT)
Closed-kinetic chain dorsiflexion will be assessed bilaterally. A standard metric tape measure will be secured to the floor and perpendicular to a wall. Participants will stand facing the wall, with their hands on the wall and their feet in a tandem stance over the secured tape measure. Keeping their second toe and center of their heel on the tape measure, participants will be instructed to perform a forward lunge in which the anterior surface of the knee of the involved limb touches the wall. Participants will gradually be moved further away from the wall in 1 cm increments until the participant can no longer touch the wall with their anterior knee and keeping their heel on the ground. The maximum distance from the wall while continuing to maintain contact with the wall and heel on the ground will be recorded as maximum dorsiflexion ROM in cm. Three trials will be performed for each limb. \\The average of the three trials for each limb will be used for statistical analysis.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
Star-Excursion Balance Test (SEBT)
Dynamic balance will be assessed bilaterally. The anterior, posteromedial, and posterolateral reach directions of the SEBT will be used. Participants will maintain a single-leg stance on the involved limb while reaching for maximum distance with the non-stance limb. During the anterior reach the participant's first toe is placed at the 0 point of the tape measure, while the heel is placed at 0 on the tape measure for the posterolateral and posteromedial directions. The participant is instructed to gently touch the tape measure with the most distal part of the reaching limb while maintaining a single-leg base of support on the test limb, and then return to double-leg stance. The participant's hands must remain on their hips and the stance heel must remain in contact with the ground. Four practice trials will be performed in each direction, followed by three test trials in each direction. The average across all three trials for each direction will be used for statistical analysis.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
Static Postural Control
Static balance will be assessed bilaterally. A single-limb with eyes-open balance task will be utilized. A force platform (AccuSway Plus, AMTI, Watertown, MA) integrated with Balance Clinic software (AMTI, Watertown, MA) will be used to record center of pressure (COP) trajectories in the anteroposterior (AP) and mediolateral (ML) directions at a sampling rate of 100Hz. Participants will be asked to balance in a barefoot single-limb stance on the middle of the force platform, keep their hands on the chest, and stare at an "X" in front of them while keeping their foot flat on the force plate. Participants will be allowed three practice trials and then asked to perform three testing trials with their eyes-open. Participants will be instructed to balance quietly in a single-limb stance for 20 seconds while COP data will be collected. The COP velocity (COPV) (cm/s) and measures of time-to-boundary (TTB) (sec) in each direction will be calculated.
Time frame: Change from baseline at 24-72 hours immediately post intervention AND change from immediately post intervention at 1 month.
