Ankle dorsiflexion range of motion influences dynamic balance in individuals with chronic ankle instability.

ABSTRACT: UNLABELLED:PURPOSEBACKGROUND: Individuals with chronic ankle instability (CAI) often have impairments in ankle range of motion (ROM) and balance. There is limited evidence that these impairments are related in individuals with CAI. The purpose of this study was to determine the relationship between ankle dorsiflexion ROM and dynamic balance in individuals with CAI. METHODS:Forty-five participants (age=23.2±2.8 y, height=172.1±10.8 cm, mass=70.6±13.3 kg, Foot and Ankle Ability Measure Sport= 71.2±11.7, Modified Ankle Instability Instrument= 6.4±1.3) volunteered for this study. Ankle dorsiflexion ROM was measured in a weight-bearing position while dynamic balance was measured using the Star Excursion Balance Test (SEBT) in the anterior, posteromedial, and posterolateral directions. Linear regression was used to determine the relationship between ankle dorsiflexion ROM and measures of dynamic balance. RESULTS:There were fair positive correlations between dorsiflexion ROM and the anterior reach direction (r = .55, r(2) = .31, P < .001), posterolateral reach direction (r = .29, r(2) = .09, P = .03), and the composite SEBT scores (r = .30, r(2) = .09, P= .02). There was little or no relationship between ankle dorsiflexion and the posteromedial reach direction (r = .01, r(2) = .001, P = .47). CONCLUSIONS:Ankle dorsiflexion ROM can influence dynamic balance, specifically the anterior reach portion of the SEBT. CLINICAL RELEVANCE:Individuals with CAI who demonstrate impairments in dorsiflexion ROM may also demonstrate difficulty with portions of the SEBT. Clinicians may use this information to better optimize rehabilitation programs that address ankle dorsiflexion ROM and dynamic balance. LEVEL OF EVIDENCE:5.

Project description:Background: Ankle sprains are common among physically active individuals, especially among athletes. Majority of those who suffer ankle sprains have residual symptoms including pain, episodes of giving way, compromised proprioception and neuromuscular control, and re-injury leading to chronic ankle instability. The aim of this study was to see the effect of chronic ankle sprain on pain, range of motion, proprioception, and, static and dynamic balance among athletes. Methods: A total of 80 athletes, aged 18 to 25 years, involved in track-and-field sports were invited to participate in this study. They were divided in two groups. Athletes with history of grade 1 or 2 ankle sprain on either side requiring medical care who reported at least three episodes of ankle giving way in past 12 months were included in group A. An equal number of healthy athletes without any history of ankle sprain or injury in the lower limbs in the past one year matched by sex, age, height, weight, and limb dominance, were included in group B (control). Outcome measures: Participant's pain, range of motion, proprioception and balance (static and dynamic) was measured using visual analog scale, half circle goniometer, degree of foot position sense, single leg stance time and Y-balance test respectively. Results: Although there were no differences in the active ankle joint range of motion (p > 0.05) in comparison to the control group, athletes with chronic ankle sprain reported mild pain and statistically significant (p < 0.05) deficits in foot proprioception, static and dynamic balance. Conclusions: Deficits in foot proprioception, static and dynamic balance even one year after the ankle sprain could be the reason for limitations in the dynamic defense system of the joint that predisposes to recurrent injury and instability. It is essential to understand the normal clinical course and risk factors for athletes who sustain sprain before devising a long term comprehensive rehabilitation program that focuses on mechanical and functional insufficiencies in order to improve their functional performance and prevent the risk of recurrent sprain.

Project description:BACKGROUND:New reliable devices for range of motion (ROM) measures in older adults are necessary to improve knowledge about the functional capability in this population. Dorsiflexion ROM limitation is associated with ankle injuries, foot pain, lower limb disorders, loss of balance, gait control disorders and fall risk in older adults. The aim of the present study was to assess the validity and reliability of the Leg Motion device for measuring ankle dorsiflexion ROM in older adults. METHODS:Adescriptive repeated-measures study was designed to test the reliability of Leg Motion in thirty-three healthy elderly patients older than 65 years. The subjects had to meet the following inclusion and exclusion criteria in their medical records: older than 65 years; no lower extremity injury for at least one year prior to evaluation (meniscopathy, or fractures) and any chronic injuries (e.g., osteoarthritis); no previous hip, knee or ankle surgery; no neuropathic alterations and no cognitive conditions (e.g., Alzheimer's disease or dementia). Participants were recruited through the person responsible for the physiotherapist area from a nursing center. The subjects were evaluated in two different sessions at the same time of day, and there was a break of two weeks between sessions. To test the validity of the Leg Motion system, the participants were measured in a weight-bearing lunge position using a classic goniometer with 1° increments, a smartphone with an inclinometer standard app (iPhone 5S®) with 1° increments and a measuring tape that could measure 0.1 cm. All testing was performed while the patients were barefoot. The researcher had ten years of experience as a physiotherapist using goniometer, tape measure and inclinometer devices. RESULTS:Mean values and standard deviations were as follows: Leg Motion (right 5.15 ± 3.08; left 5.19 ± 2.98), tape measure (right 5.12 ± 3.08; left 5.12 ± 2.80), goniometer (right 45.87° ± 4.98; left 44.50° ± 5.54) and inclinometer app (right 46.53° ± 4.79; left 45.27° ± 5.19). The paired t-test showed no significant differences between the limbs or between the test and re-test values. The test re-test reliability results for Leg Motion were as follows: the standard error of the measurement ranged from 0.29 to 0.43 cm, the minimal detectable difference ranged from 0.79 to 1.19 cm, and the intraclass correlation coefficients (ICC) values ranged from 0.97 to 0.98. CONCLUSIONS:The results of the present study indicated that the Leg Motion device is a valid, reliable, accessible and portable tool as an alternative to the classic weight-bearing lunge test for measuring ankle dorsiflexion ROM in older adults.
