Comparison of Muscle Activity of Lower Limbs in Bridging Exercise according to Knee Joint Angle

The purpose of this study is to identify the bridge exercise posture for the efficient exercise by comparing the muscle activity of the lower limbs according to the changes in muscle length because of knee angle in bridge exercise. The subjects of this study were 9 randomly selected males in their 20s living in D city from those who satisfied inclusion criteria. The measured muscles were Vastus medialis oblique, Vastus lateralis, Semitendinosus, Biceps femoris, Gluteus maximus, Gluteus medius, Tensor faciae latae, and Adductor longus. Data were analyzed through paired comparison test. In the result, ST, BF, and TFL muscle activities were high when knee joint flexion angle was 90°Although in most cases higher muscle activity was shown at 90°than 60°there was no statistical significance. Interestingly, it was lower at 90°than 60°in VL. In ST, BF, and TFL, it was significantly higher at 90°han 60°(p<.05). Conclusively, knee angles in bridge exercise may affect the muscle activity, and in particular when the activity of two joint muscles such as semimenbranosus muscle, biceps femoris muscle, and tensor fasciae latae muscle increase as the angle gets higher. Therefore, it is considered that this study will provide helpful tips to develop muscular strength enforcement program for the patients with damages in the lower limbs through bridge exercise in clinical situations.

These results suggest that virtual reality training using virtual reality cognitive rehabilitation program is feasible and suitable for mild dementia.

The Study on Respiratory Function, Spirometric Lung Pattern and Fatigue of Elderly in a Facility

The purpose of this study was to investigate spirometric lung pattern, respiratory function and degree of fatigue by lung function tests and fatigue tests of 39 elderly people in a care facility aged 65 and over. The respiratory function tests were used to the Spirovit SP-1 and fatigue tests were used modified Piper fatigue scale(mPFS). Regarding the respiratory function, the FVC was l, the FVC % predicted was %, the was l, the % predicted was %, the /FVC was %, and the fatigue score was . As for the spirometric lung pattern, 19 patients had a restrictive pattern(48.7%), followed by 11 with a mixed pattern(28.2%), 5 with an obstructive pattern( 12.8%), and 4 with a normal pattern(10.3%). Regarding the respiratory function and fatigue by spirometric lung pattern, the FVC and the FVC % predicted of patients with a normal pattern or an obstructive pattern were greater than other groups at a statistically significant level. As for the , that of patients with a normal pattern was significantly higher than others, and for the % predicted, that of patients with a normal pattern or a restrictive pattern was significantly higher(p

Influences of Chronic Shoulder Pain on Muscle Tone Changes in Trunk Muscles

The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study``s subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

Effects of Therapeutic Ball Exercise and Hippotherapy for Balance Ability in Elderly

Fall accidents in old age are primarily caused bylowered balancing abilities including bone density,muscular strength, flexibility, power, and stabilityaccording to decreased amounts of exercise, accord-ingly having a very high risk(1). It was reported thatprograms designed to increase balance, flexibility,and response time improved the balance and percep-tual exercise of the elderly and thus contributed totheir stability(2) and that programs based on aerobicexercise, active strength exercise, long walk, postureadjustment, and repeating muscular coordinationexercise increased balance and mobility and reducedand prevented falls(3, 4).There have been many researches to help toincrease balancing abilities, which have much influ-ence on fall. Research efforts have recently beenactive to help the elderly reduce pain and increasestability, flexibility, and muscular strength throughtherapeutic ball exercise with positive effects onhealth, the muscles in the waist, pelvis, and trunk,and balance reported(5, 6). The elderly more and moreexperience a fall accident with aging and desperatelyneed efforts to prevent such an accident. With theincreasing elderly population, it is further importantto raise the quality of life in old age. Illness-basedaging rather than simple aging is emerging as asocial issue beyond the individual economic level.The number of proper exercise programs to help theelderly prevent a fall is low in reality. This studythus set out to investigate the effects of ball exerciseand hippotherapy, which are both a regular and eas-ily applicable exercise enough to induce interest andfun in the elderly and thus settle down as an elderlyexercise program and consists of simple and easymovements, on the balancing abilities of the elderly. The subjects include the male and female elderlyaged 65 or older according to the Elderly Welfare Actand hospitalized in a nursing hospital in Gyeonggi
