Alteration in ankle kinematics during uneven surface ambulation in stroke survivors: An exploratory observational study

Abstract

BACKGROUND: Impaired walking ability is a common disability in stroke survivors and is a known risk factor of fall. Navigation of uneven terrain is essential for rural residents of regions in much of the developing world even for basic activities of daily living. AIMS: This is a preliminary exploratory study to evaluate kinematic gait parameters of the ankle joint in stroke survivors in comparison to typical adults. MATERIALS AND METHODS: Seven chronic adult stroke survivors and seven age-matched typical adults were recruited for the study. Measurement of ankle and subtalar joint kinematics at different events of the gait cycle was recorded and analyzed using a motion analyzing software, Kinovea 0.8.15. Settings and Design: This is a prospective pilot study. Statistical Analysis Used: Descriptive statistics. RESULTS: During different events of the gait cycle, a large difference in range of motion in ankle and subtalar joints was noticed between stroke survivors and typical participants on pebbles and sand. CONCLUSIONS: The impact of gait deviations on joint kinetics is a future direction that will inform rehabilitation professionals on strategies to prevent joint loading, leading to dysfunction. Early intervention strategies to improve joint kinematics on different surfaces can potentially reduce the risk of fall, making the patient safe to ambulate on uneven terrains.
