Effects of balance training by knee joint motions on muscle activity in adult men with functional ankle instability

Abstract

[Purpose] This study examined the effects of balance training by applying knee joint movements on muscle activity in male adults with functional ankle instability. [Subjects and Methods] 28 adults with functional ankle instability, divided randomly into an experimental group, which performed balance training by applying knee joint movements for 20 minutes and ankle joint exercises for 10 minutes, and a control group, which performed ankle joint exercise for 30 minutes. Exercises were completed three times a week for 8 weeks. Electromyographic values of the tibialis anterior, peroneus longus, peroneus brevis, and the lateral gastrocnemius muscles were obtained to compare and analyze muscle activity before and after the experiments in each group. [Results] The experimental group had significant increases in muscle activity in the tibialis anterior, peroneus longus, and lateral gastrocnemius muscles, while muscle activity in the peroneus brevis increased without significance. The control group had significant increases in muscle activity in the tibialis anterior and peroneus longus, while muscle activity in the peroneus brevis and lateral gastrocnemius muscles increased without significance. [Conclusion] In conclusion, balance training by applying knee joint movements can be recommended as a treatment method for patients with functional ankle instability.

Effects of visual feedback balance training on the balance and ankle instability in adult men with functional ankle instability

“…Moreover, the present study showed that the CAIT score increases were statistically significant in both the experimental and the control groups because the training improved muscle strength around the ankles and thereby reduced subjective feelings of ankle instability. The present study’s results were consistent with those of previous studies, in which balance training and muscle strengthening exercises increased muscle activity around ankles, including the tibialis anterior and peroneus longus muscles, as well as isokinetic muscular strength, improving ankle stability 1 , 14 ) .…”

“…A tilt sensor detects the angle of flexion and extension of the knee joints. For example, when the knees are bent, a cursor is raised, and when the knees are extended, a cursor descends, thereby performing training to touch various fruits arranged randomly on a tree on the screen 1 , 9 ) . The visual feedback balance training was conducted three times a week for 8 weeks.…”

“…In recent years, participation in sports has increased, resulting in an increase in sports-related injuries. These injuries frequently involve the lower extremities, with sprains of ankle joints, which damage the lateral ankles due to inversion, accounting for 85% of the incidents 1 , 2 ) . Among patients with ankle-joint sprains, 20% to 40% progress into functional ankle instability, which refers to repetitive ankle sprains or re-damage, and complain of the subjective feeling that the ankle may give way during daily activities 3 ) .…”

Effects of balance training on movement control, balance and performance in females with chronic ankle instability

“…Evidence suggests that balance-training program of short to moderate duration over the course of at least 4 weeks can improve objective and subjective measures of function in persons with musculoskeletal injuries (eg, CAI) and uninjured control participants. Using a progressive style, 4week balance-training programs including a combination of low-impact and dynamic activities have also improved self-assessed disability and postural control in those with CAI (1,(20)(21)(22)(23)(24).…”

Information Processing Speed and Accuracy in Basketball Players With and Without Functional Ankle Instability

“…Subjects with FAI were included in the study if their ages were between 20 and 30 years, had at least 1 significant unilateral inversion sprain of either ankle that resulted in pain, swelling, and loss of function within last year, followed by more than 1 repeated injury or the perception of ankle instability or "giving way", no recent lower-limb or low back pathology, no evidence of mechanical instability as assessed by the anterior drawer and talar tilt tests, no reported history of ankle injury within the last 3 months. Subjects in the FAI group had 1 to 3 ankle sprains within the previous 12 months, and the Cumberland Ankle Instability Tool (CAIT) score lower than 24 [24][25][26][27].…”
