PURPOSE: In this study, we sought to investigate the effect of conservative ankle strengthening exercise programs using a Bosu® ball or taping, on the hallux valgus angle and the pain of hallux valgus patients in their 20s. METHODS: The hallux valgus angle, balance, and pain after measuring the hallux valgus were measured to select suitable subjects. In the ankle strengthening exercise group (ASG) an ankle strengthening exercise program using a Bosu® ball was performed for two sessions weekly for four weeks and the taping group (TG) was given Kinesiotaping® for two sessions weekly, two days per session, for four weeks. Before and after the experiment, a footprint was used to examine the changes in the hallux valgus angle and the visual analog scale (VAS) was used to measure pain. RESULTS: An evaluation of the post-experiment changes in the hallux valgus angle and pain showed statistically significant improvement in both groups. There was no statistically significant improvement between groups. CONCLUSION: These results show that both ankle strengthening exercises and Kinesiotaping® have a positive effect on the hallux valgus angle and pain.

This study was conducted to investigate the effect of ankle muscle strengthening exercise using BOSU ball and taping on static and dynamic plantar pressure in patients with hallux valgus. Subjects were 26 men and women in their twenties with hallux valgus, and they were randomly assigned to a taping group (TG; n=13) and an ankle strengthening group (ASG; n=13). Each group received the appropriate intervention over a total of 4 weeks, and static and dynamic plantar pressure were measured before and after the intervention. Independent T-test was performed to examine the difference in the amount of change between groups, and paired-sample T-test was performed to determine whether the difference between the pre-post values within the group was significant. The statistical significance level was set as α=.05. As for the ratio of the total body weight of the foot (Foot), the amount of change in the ASG of the left foot was significantly decreased compared to the TG within the group (p<.05). Significantly increased (p<.05). As for the degree of pronation of the foot (MP/change ratio), the amount of change in the TG of the right foot was significantly decreased compared to the ASG (p<.05), and in the force of the foot, the TG of the left foot was the amount of change within the group compared to the ASG. was significantly increased (p<.05), and in the group-to-group change, the amount of change in TG was significantly different than that of ASG (p<.05). Therefore, it can be considered that ankle strengthening exercise using bosu ball and taping are insufficient to give effective change to patients with hallux valgus.

This study examined the effects of trunk stabilization exercise on balance and trunk control in children with spastic diplegia. Four children with ambulatory spastic diplegia participated in the trunk stabilization exercise program using a Both Sides Utilized (BOSU) ball, 30 minutes a day, two times a week for eight weeks. Outcome variables included the pediatric balance scale, trunk control movement scale and multifidus thickness using ultrasound image. After trunk stabilization exercise, there was statistically no significant improvement in pediatric balance scale, trunk control movement scale and multifidus thickness. However, individual outcomes were observed with some positive changes. Balance, trunk control movement, and thickness of multifidus were found to be improved. Trunk stabilization exercise using a BOSU ball could improve trunk control and increase the thickness of multifidus in children with spastic diplegia. Further investigation is needed to evaluate subjects according to type of cerebral palsy and to understand the relationship between postural control and gait.

The purpose of this study was to examine the muscle activation in trunk and low-limbs muscle during squat exercise on various instability surface. 10 subject performed squat with 75% of 1 repetition maximum (1RM) on a stable floor, stability blue, stability black and BOSU. Electromyographic (EMG) activity was measured trunk muscle such as rectus abdomina (RA), external obliques (EO), internal obliques (IO), multifidus (MF), and low-limbs muscle such as gluteus maximus (GMA), gluteus medius (GME), biceps femoris (BF), rectus femoris (RF), vastus medialis oblique (VMO), vastus lateral oblique (VLO), medialis gastrocnemius (MG), lateral gastrocnemius (LG), soleus (SOL) and anterior tibia (AT) when ascending and descending squat phase. One-way ANOVA repeated measure with Sheffe used to compare the muscle activity on the stable and unstable surface. Squat with BOSU ball induces higher muscle activity of IO, MF, GMA and GME compared with stability and stability blue and blackduring descending motion. Squat with BOSU ball induces higher muscle activity of GMA compared with stability and stability blue and blackduring ascending motion. This results suggested that BOSU ball in the squat could be effective increasing of trunk stability and gluteal muscle activity. However, there was no difference of squat on low-limb muscle with or without instability.

The purpose of this study was to effectively improve the thigh muscles of adult women working from home due to COVID-19. In this study, ten adult women working from home performed 1) an electromyography test, 2) a static balance test on a balance board, and a 3) dynamic balance test by squatting on a Bosu ball four times: before electric muscle stimulation (EMS), after EMS, after high-intensity circuit training (HICT), and after EMS plus HICT. For this test, EMS was attached to a medical knee support to manufacture an EMS knee band that could be easily worn regardless of the location. For the experiment, EMS(electric muscle stimulation) was attached to the medical knee protector to manufacture an EMS knee band that can be easily worn regardless of location, and was measured based on the right foot. The study results confirmed that in all tests (electromyography test, static balance test on the balance board, and dynamic balance test by squatting on a Bosu ball), thigh strength improved in the order of treatment before EMS, after EMS, after HICT, and after EMS plus HICT. The study showed that people working from home or with activity restrictions due to COVID-19 had better exercise effects when wearing the EMS knee band and performing HICT, even in a small space.

The aim of this study was to examine the comparative analysis of body muscle EMGs according to the prop and different foot stability during Pilates bridge motion. Eighteen adult males(age, 22.3±2.1 years; height, 173.89±4.51 cm; body mass, 72.61±4.13 kg; and BMI, 24.03±1.31 kg/m²) participated in this study as subjects. The Pilates bridge was composed of a total of 9 motions, according to the props (NP, no prop; RG, ring; GB, gym ball) and different foot stability (BS, basic surface; FR, form roller; BOSU, both sides up). We measured the right's muscle activities of the upper rectus abdominis, lower abdominal stabilizers, external oblique, adductor longus, rectus femoris, vastus lateralis, tibialis anterior, and biceps femoris. The research findings were as follows. During Pilates bridge motion, the use of GB was found to be more effective in activating the body muscle. And during Pilates bridge motion, the use of BOSU was found to be most high in activating the body muscle as well. To summarize the research findings, the use of GB and BOSU during Pilates bridge motion were discovered to enormous affect muscle activities. Therefore, the results of this study are expected to be able to present efficient Pilates bridge exercises for strengthening physical strength.
