Effect of a 4-week balance exercise with medio-lateral unstable sole on ankle joint functional ability

Abstract

[Purpose] This study examined the effects of 4-week of balance exercise with medio-lateral unstable sole on ankle muscle activation and functional ability. [Subjects and Methods] Thirty university students without current or past ankle injuries were assigned to either an experimental group or control group. The experimental group participated in a balance exercise program 3 times a week over 4 weeks, which consisted of one-leg stands and semi-squat exercises with medio-lateral unstable sole. The control group continued with their regular life activities without participation in the program. Electromyographic activities of peroneus longus and brevis muscles were recorded during stair descending immediately before and after the exercise program. Functional balance was tested with the Star Excursion Balance test immediately before and after the exercise program. Paired t-tests were used to assess statistical significance. [Results] Activation of peroneus longus and brevis and Star Excursion Balance Test scores in both groups did not show a significant difference between pre- and post-exercise. [Conclusion] A future study is suggested with increased level of medio-lateral perturbation during outcome measurements and exercises with addition of supervision in the exercise training and home program.

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

“…Clinicians who include balance training as a rehabilitation intervention in subjects with CAI to address sensorimotor control should consider the variety of tasks that can be performed to gain improvements in postural stability. This portion of our results is consistent with Nam et al (2017) that reported after intervention Star Excursion Balance Test scores did not show a significant difference between pre-and postexercise but only differences was in instrumentation that them used star excursion balance test (12).…”

“…Functional performance tests range from general lower extremity tests to unilateral hopping tests. Second, the improvement in Y-Balance scores that seen with either rehabilitation protocol conflicts with the findings of an earlier study that used a multicomponent rehabilitation protocol that resulted in significant improvements in scores of Star Excursion Balance Test (12). However, it is likely that the improvements seen in that study stemmed from the balance exercises included in that protocol, rather than the strengthening exercises (2).…”

“…Ju (2017) studied the effects of ankle functional rehabilitation exercise on the ankle joint functional movement screen and isokinetic muscular function in patients with chronic ankle sprain and reported significant improvements in ankle joint functional movement screen and in isokinetic muscular function after the exercise (11). Nam et al (2017) examined the effect of a 4-week balance exercise with medio-lateral unstable sole on ankle joint functional ability and reported after intervention Star Excursion Balance Test scores did not show a significant difference between pre-and post-exercise. Nam suggested a future study with increased level of medio-lateral perturbation during outcome measurements and exercises with addition of supervision in the exercise training and home program (12).…”

Nam suggested a future study with increased level of medio-lateral perturbation during outcome measurements and exercises with addition of supervision in the exercise training and home program (12). Because a high percentage of ankle sprain cases are associated with residual functional deficiencies, there is a need to identify effective clinical interventions that address the long-term deficits associated with CAI (4,10).…”

Examining the Use of Kinesiology Tape During Weight Bearing Exercises on Proprioception in Participants With Functional Ankle Instability

“…Weight bearing exercises cause joint approximation, improve co-contraction of agonist and antagonist muscles, improve movement control, dynamic stability, and neuromuscular control, and improve proprioception and balance (Kisner & Colby, 2002;Sulivan et al, 1982;Sullivan et al, 2001;Voss et al, 1985). Past studies revealed that weight bearing and balancing exercises can improve balance parameters in a posterior-medial direction during standing balancing tests such as the star excursion balance test (Burcal et al, 2019), both the posterior-anterior index and the overall index of balance (Youssef et al, 2018), increased activity of peroneal muscles (Nam & Choi, 2017;Yoshida et al, 2015), decreased ankle instability when landing from a jump (Yoshida et al, 2015), and increased power (Smith et al, 2012). Some studies have reported that these exercises, in combination with other exercises, improve proprioception; however, when these exercises were used alone they did not decrease angle repositioning error (Amrinder et al, 2012;Eils & Rosenbaum, 2001;Ha et al, 2018;Lee et al, 2019;Liu et al, 2012) .…”
