PURPOSE: The aim of this study is to find a more efficient intervention method through a study of the gait variables and dynamic balance of chronic neck pain patients. METHODS: Forty subjects aged between 40 and 60 years were allocated randomly to two groups; The first group performed PA (Posteroanterior Mobilization), and the second group conducted CCF (Craniocervical Flexion Exercise). The gait variability measured the speed, cadence, and dynamic balance in the forward, leftward, rightward, and rearward directions. An independent t-test, Wilcoxon signed-rank test, and paired t-test were used for statistical analysis. RESULTS: In the dynamic balance measurements, the variability of PA (p < .000) and CCF (p < .000) in the rightward direction, PA (p < .004) in leftward direction and forward direction increased significantly (p < .013). In an analysis of the gait variability, the cadence increased significantly in the PA group (p < .022) and not significantly in the CCF group (p < .056). On the other hand, there was no increase in the speed variable, in the PA group (p < .437). In the CCF group, the cadence increased significantly (p < .022). The differences in the PA and CCF group differences were not significant. CONCLUSION: The PA group showed a significant increase in the forward (p < .013), leftward (p < .004), and rightward directions (p < .000). Speed was significant in the CCF group, and cadence was significant in the PA group. The dynamic Balance was effective in the rightward direction in both groups, but there was no significant difference between the two groups.

Background: In previous studies regarding flexible pes planus, Foot orthosis, special shoes have been used as interventions for correcting malalignment and intrinsic muscles strengthening exercise have been regarded as interventions for foot function and supporting medial longitudinal arch during walking. However, some recent studies reported that strengthening extrinsic muscles as well as intrinsic muscles is more effective and active intervention for flexible pes planus. In particular, the tibialis posterior muscle of foot extrinsic muscles plays essential roles in maintaining the medial longitudinal arch during dynamic weight bearing and balance. In addition this muscle acts longer than other supination muscles during the stance phase in the gait cycle. Objects: This study aimed to investigate the effect of foot intrinsic muscle and tibialis posterior muscle strengthening exercise for plantar pressure and dynamic balance in adults with flexible pes planus. Methods: 16 young flexible pes planus adults (7 males, 9 females) were recruited and were randomized into two groups. The experimental group performed foot intrinsic muscle and tibialis posterior muscle strengthening training, the control group performed only foot intrinsic muscle strengthening training. All groups received strengthening training for 30 minutes five times a week for six weeks. Results: The experimental group had significantly lower plantar pressure of medial heel area than the control group in stand (p<.05). The experimental group had significantly higher dynamic balance ability than control group (p<.05). Conclusion: The results of this study provide evidence to suggest that foot intrinsic muscle and tibialis posterior muscle of extrinsic muscle strengthening exercises may improve plantar pressure distribution and dynamic balance ability in adults with flexible pes planus.

Purpose: The purpose of this study was to investigate the effects of using proprioceptive neuromuscular facilitation (PNF) exercise in the progressive sitting position on the dynamic balance ability of a patient with a cerebellar injury. Methods: The subject had ataxia due to cerebellar injury. The subject participated in a PNF bilateral scapular pattern exercise with stabilizing reversal technique during a progressive sitting position session as well as baseline for 20 minutes a day for 4 weeks. In the first session, PNF exercises were performed at a height of 40 cm for 10 minutes, and in the second session they were performed at 50 cm for 10 minutes from a lower center of gravity (COG) to a higher COG sitting position. We used the Berg Balance Scale (BBS), Five-Times-Sit-to-Stand Test (FTSST), and the Timed Up and Go Test (TUGT) to measure the subject's dynamic balance ability every two days through the entire session. Results: After participating in the program, the subject's dynamic balance ability improved compared to the first baseline, as measured by BBS (2 points increased), FTSST (5.3 sec decreased), and TUGT (2 sec decreased). The increase was also maintained in the second baseline session. Conclusion: PNF exercise using bilateral scapula patterns with a stabilizing reversal technique helps to enhance the dynamic balance ability of a cerebellar injury patient.

The purpose of this study is to identify the effects of two trunk stability exercise types on the gait factors of stroke patients. We randomly divided 24 old elderly patients with hemiplegia, who were hospitalized due to stroke, into a two groups, each with its own six-week exercise program: one that used of a dynamic trunk stability exercise using with physio-balls(n=12) and a group of one that used a static trunk stability exercise using on mats(n=12). After measuring the participants gait ability a sin a pre-test, we again measured their ability again as in a posttest after two-for both types of six-week exercise programs for each group. The analysis of the data analysis showed that both ball and mat exercise programs significantly improved the participants' gait velocity and stride length; cadence, however, was significantly changed only by the ball exercise program. In conclusion, both types of trunk stability exercise may be useful in improving the gait ability of stroke patients, and, in particular, the former can be used as an exercise method that effectively significantly affects more various other gait factors.

Muscle atrophy is characterized by the loss of muscle function. Many efforts are being made to prevent muscle atrophy, and exercise is an important alternative. Methylglyoxal is a well-known causative agent of metabolic diseases and diabetic complications. This study aimed to evaluate whether methylglyoxal induces muscle atrophy and to evaluate the ameliorative effect of moderate-intensity aerobic exercise in a methylglyoxal-induced muscle atrophy animal model. Each mouse was randomly divided into three groups: control, methylglyoxal-treated, and methylglyoxal-treated within aerobic exercise. In the exercise group, each mouse was trained on a treadmill for 2 weeks. On the last day, all groups were evaluated for several atrophic behaviors and skeletal muscles, including the soleus, plantaris, gastrocnemius, and extensor digitorum longus were analyzed. In the exercise group, muscle mass was restored, causing in attenuation of muscle atrophy. The gastrocnemius and extensor digitorum longus muscles showed improved fiber cross-sectional area and reduced myofibrils. Further, they produced regulated atrophy-related proteins (i.e., muscle atrophy F-box, muscle RING-finger protein-1, and myosin heavy chain), indicating that aerobic exercise stimulated their muscle sensitivity to reverse skeletal muscle atrophy. In conclusion, shortness of the gastrocnemius caused by methylglyoxal may induce the dynamic imbalance of skeletal muscle atrophy, thus methylglyoxal may be a key target for treating skeletal muscle atrophy. To this end, aerobic exercise may be a powerful tool for regulating methylglyoxal-induced skeletal muscle atrophy.

The purpose of this study is to examine the effect of stabilization, resistance exercise, and combined exercise for lumbar on balance and walking ability of elderly. This study selected 22 subjects of over 65 years old elderly women who satisfy the study condition from A, B and C Senior Citizen's Center, in Daegu. The subjects were divided into groups; 7 for resistance exercise group, 8 for stabilization exercise group, and 7 for combined exercise group(resistance and stabilization exercise). The exercises were conducted for 60min a day, three times a week for 12 weeks. Balance and walking ability were checked before the exercise, 6 weeks later, and 12 weeks later. First, all lumbar muscle strengthening exercises were effective for static balance which changed according to exercising period. In dynamic balance, the resistance exercise group showed significant improvement in sit to stand. Stabilization exercise group showed significant improvement in all factors. The combined exercise group showed significant improvement in sit to stand and timed up and go. There was no difference between the exercise types. Second, the resistance exercise group showed significant change in Cadence which changed according to exercising period. The combined exercise group showed significant improvement in all factors. Between the exercise types, combined exercise was a bit more effective than resistance exercise. According to the result of 12 weeks of lumbar muscle exercise, combined exercise is considered to be the most effective exercise to prevent fall as it helps balance and walking ability slightly more than other exercises. Therefore, this study can understand the risk factors for fall accidents that frequently occur among elderly and adopt the combined exercise to prevent fall which in turn will prevent secondary problems occur from fall accidents and improve quality of life of elderly.
