Objective: The aim of this study was to analyze kinetic variables between thermotherapy and dynamic warm-up during drop-landing. Method: Twenty male healthy subjects (Age: 21.85 ± 1.90 years, Height: 1.81 ± 0.06 cm, Weight: 68.5 ± 7.06 kg) underwent three treatments applied on the thermotherapy of femoral muscles and a dynamic warm-up. The thermotherapy was performed for 15 minutes while sitting in a chair using an electric heating pad equipped with a temperature control device. Dynamic warm-up performed 14 exercise, a non-treatment was sitting in a chair for 15 minutes. Core temperature measurements of all subjects were performed before landing at a height of 50 cm. During drop-landing, core temperature, joint angle, moment, work of the sagittal plane was collected and analyzed. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was Bonferroni. Results: Results indicated that Thermotherapy was increased temperature than other treatments (p = .000). During drop-landing, hip joint of dynamic warm-up was slower for angular velocity (p < .005), and left ankle joint was fastest than other treatments (p = .004). Maximum joint moment of dynamic warm-up was smaller for three joints (hip extension: p = .000; knee flexion/extension: p = .001/.000; ankle plantarflexion: p = .000). Negative work of dynamic warm-up was smaller than other treatments (p = .000). Conclusion: In conclusion, the thermotherapy in the local area doesn't affect the eccentric contraction of the thigh. The dynamic warm-up treatment minimized the joint moment and negative work of the lower joint during an eccentric contraction, it was confirmed that more active movement was performed than other treatment methods.

Background: This study was designed to investigate the correlation between electromyography (EMG) activities in the vastus medialis oblique (VMO) vs vastus lateralis (VL) activity ratio and the valgus collapse knee position while stepping down. Methods: Twenty healthy women volunteered to participate in this study. We measured the frontal-plane projections of the knee valgus angle, knee valgus distance, and hip adduction angle by using a digital camcorder. After 3 repetitions of the step down (dominant side) exercise, the findings of the static and dynamic phases were analyzed. EMG activities data of the VMO:VL activity ratio were recorded during the step down exercise and were normalized to the maximal voluntary isometric contraction (MVIC) of the quadriceps. A paired t-test was used to compare the findings of the static and dynamic phases. We analyzed the Spearman's rank order correlation coefficient between the and VMO:VL ratio. Results: Hip adduction angle, knee valgus angle, VMO activity, VL activity, VMO:VL activity ratio were statistically higher in the dynamic phase than in the static phase (p<.05). Frontal-plane projections of knee valgus angle were significantly correlated with hip adduction angle (r=.459, p<.05) and knee valgus distance (r=.505, p<.05). However, the EMG activity ratio of the VMO and the VL did not show a significant change during step down exercise with respect to hip adduction angle (p=.875), knee valgus angle (p=.618), and knee valgus distance (p=.701). Conclusion: The results from this study indicate that frontal-plane projections of knee valgus angle were associated with hip adduction angle and knee valgus distance. On the basis of these results, the knee valgus distance may be used to determine the valgus collapse knee position while stepping down.

PURPOSE: This study evaluated an intrinsic foot strengthening exercise method for flat feet by comparing the effects of intrinsic exercises on a stable surface and intrinsic exercises on an unstable surface. METHODS: Twenty-four people with flat feet were divided into two groups. The control group performed short foot exercises and toe towel curl exercises on the stable support surface. The experimental group performed short foot exercises and toe towel curl exercises on an unstable support surface using Aerostep. The navicular drop test, and the static and dynamic balance were measured before and after the intervention. RESULTS: In the experimental and control groups, there was a significant difference in the navicular drop test and static balance before and after the intervention (p < .05). On the other hand, there was no significant difference between the two groups (p > .05). In the dynamic balance, the experimental group showed significant differences in all directions after the intervention (p < .05). The control group showed significant differences in the postero-lateral direction and posteromedial direction (p < .05). In particular, in the forward direction, the experimental group had a more significant change than the control group (p < .05). CONCLUSION: Intrinsic foot muscle strengthening exercises performed on unstable surfaces can be an effective clinical exercise method to improve the dynamic balance ability of people with flat feet.

Purpose: The purpose of this study was to evaluate the effect of 6-week sensorimotoor training on balance ability and lower limb muscle activation during gait in older adults. Methods: Twenty-four community-dwelling older adults between 65 and 90 years of age participated in this study. In the older adults of the experimental group (n=12), the sensorimotor training program was performed bare feet. General exercise was performed in the control group (n=12). Then, both groups exercised three times a week for forty minutes over a 6-week period. Balance ability was evaluated by One leg stand (OLS) test for determining the static balance and Timed Up & Go (TUG) test for determining the dynamic balance. In addition, muscle activation of the dominant lower limb tibialis anterior and gastrocnemius medialis muscles were measured by surface EMG to evaluate muscle activation during gait. Results: A significant improvement was seen in the one leg standing (OLS) time after exercise in both the sensorimotor training (SMT) group and general exercise (GE) group (p<0.05) and the change in the SMT group was greater than that in the GE group (p<0.05). A significant reduction was seen in the Timed Up & Go (TUG) test time after exercise in both the SMT group and GE group (p<0.05). Also, a significant increase was seen in muscle activation of tibialis anterior muscle after exercise in the SMT group (p<0.05), but no such significant increase was seen in the GE group (p>0.05). Conclusion: These results suggest that sensorimotor training improves the balance in older adults and has a more positive effect on muscular strength and gait. Sensorimotor training provided a variance of training environment and COG exercise of the body is thought to be a more effective exercise program that improves balance and gait ability in older adults.
