Effects of Mobile-Based Rehabilitation in Adolescent Football Players with Recurrent Lateral Ankle Sprains during the COVID-19 Pandemic

Abstract

Football is a sport involving dynamic movements, and ankle sprains are common sports injuries experienced by football players. Ankle sprains exhibit a high recurrence rate, and rehabilitation training is effective; however, expert-supervised rehabilitation (SVR) at training centers is difficult due to the recent COVID-19 pandemic. This study investigated the effects of mobile-based rehabilitation (MBR) performed at home by high school football players. Sixty players (SVR: 30 and MBR: 30) with recurrent ankle sprains were analyzed. The rehabilitation program consisted of strength and balance training, and the training intensity was gradually increased from week 1 to week 8. The SVR group underwent training at the center with experts, and the BMR group were provided with programs and feedback using mobile devices. Ankle muscle strength was evaluated by measuring isometric eversion, inversion, plantarflexion, and dorsiflexion contraction using a hand-held dynamometer, and dynamic balance was assessed using the Y-balance test (YBT; anterior, posteromedial, and posterolateral); the Foot and Ankle Outcome Score (FAOS) was used for the subjective evaluation. Measurements were conducted at weeks 1, 4, and 8. The patients visited the clinic within 1 week after the injury, and the first test was conducted after consent to participate in the research. Patients underwent the second test at an average of 3.2 weeks after the first test, and the last test at an average of 4.4 weeks after the second test. Although only the SVR group exhibited improvement in strength (eversion and dorsiflexion), YBT and subjective satisfaction at week 4, these measurements improved in both the SVR and MBR groups at week 8. Therefore, mobile–based rehabilitation could be a suitable alternative for high school athletes with ankle sprains who cannot undergo supervised rehabilitation.

Kinetic Effects of 6 Weeks’ Pilates or Balance Training in College Soccer Players with Chronic Ankle Instability

“…In this study, the subjective ankle score evaluated by the FAOS was significantly improved after training in both groups that received PT and BT. The improvement in subjective evaluation through training intervention has already reported the same results in previous studies [12,31]. A minimal clinically important difference (MICD) was identified to confirm whether the self-reported results indicated clinically significant changes.…”

“…The purpose of the training program was to improve ankle-body coordination and stability through neuromuscular activation. The researchers reconstructed BT to fit the actual situation by referring to the prior literature [12,13,31,32]. The participants performed the BT program for 60 min per session three times a week for 6 weeks (10 min warm-up, 40 min Pilates, and 10 min cool-down), the same as the PT group.…”
