This paper proposes a somatosensory stimulation system for the improvement of postural stability using vibration as somatosensory stimulation. This system consists of vibratory stimulation and postural response measurement. To evaluate this system, the center of pressure(COP) was closely observed in turn with simultaneous or separate mechanical vibratory stimulations to flexor ankle muscles (tibialis anterior, triceps surae) and two plantar zones on both feet while standing on a stable and an unstable support. The simultaneous vibratory stimulations cleared influenced postural stability and the effects of vibrations were higher with the unstable support. In separate vibratory stimulations, the extent of the COP sway reduced when the direction of the vibratory stimulations and that of the inclination of body coincided for flexor ankle muscle stimulations. In the contrary, the extent of the COP sway increased when the direction of the stimulations and that of body inclination coincided for plantar zone stimulations. These results can be useful for the development of rehabilitation systems that utilizes somatosensory inputs for postural balance.

Recently the number of elderly have been increasing at a rapid pace in Korea. Accompanying this aged society are numerous health problems. Whit this in mind health-promotion behaviors such as physical activity. good nutrition and stress management are vitally important to the elderly in reducing the risk of Health problems, maintaining health and improving the overall quality of life. Health promotion programs for the elderly must be developed. The purpose of th is study was to determine influential cognitive factors on health-promotion behaviors and the effects of previously implemented Health promotion programs. For this, previous studies were reviewed and analyzed. The results were as follows. 1. Cognitive factors on health-promotion behaviors were internal locus of control, perceived health status, self-efficacy, concerns about health, social support, attending social activities. 2. Components of health promotion programs were exercise and health education. Exercise was performed in most programs. The effects of exercise programs were improved flexibility, muscle strength. balance, cardiopulmonary function and elevated ability of daily living, perceived health status, quality of lift and a decrease depression. The results strongly suggest that complex health promotion programs should be developed. Health promotion programs need to include exercise, health education, health counseling and social activities. We have to consider cognitive factors on health-promotion behaviors.

Purpose : This study aims to examine effects of trunk strengthening exercise in three rigid cerebral palsy adolescents aged between 11 and 13 on their spinal segments and gait. Methods : 2A trunk strengthening program for proprioceptive neuromuscular facilitation was made focusing on improvement in their school life and mental and social activities during their school years, and then trunk strengthening exercise was applied to the three subjects for 30 minutes five times per week for four weeks. With the subjects in a static state, each group's gait analysis was made and maximum anterior flexion, maximum extension, maximum left and right lateral flexion, and cross rotation of the trunk were measured using Sonosens (Germany) prior to and after the intervention. Results : Assessment of spinal segment mobility with the subjects in a static state showed that the trunk muscle strengthening exercise increased their maximum joint movement angles from the right side to the center and rotational abilities of the cervical and lumbar spines. Gait analysis indicated increased movements in the thoracic and lumbar spines and relatively decreased anterior-posterior movement of the cervical spine. Conclusion : Trunk strengthening program is effective in enhancing spinal segment mobility and balance ability of cerebral palsy adolescents and considered able to be used together with diverse treatment interventions.

We conducted this study to analyze the effectiveness of a treatment called 12-week therapeutic recreation dance movement (TRDM) to elderly people in terms of health care and recovery. Forty two elderly people were participated in this study and divided into two groups with healthy (twelve) and unhealthy (thirty). After TRDM treatment, the muscular power was increased in both groups without statistical significance within and between groups. The flexibility, agility and balance were slightly increased in both groups. Although the elevation of muscular endurance was not significant between groups, it was statistically meaningful within groups. The results of body composition comparison did not reveal meaningful difference within and between groups. However, the amount of fat in serum and fat distribution percentages ware decreased in both groups. Both group appeared to be increased muscle mass. The level of body water was decreased in healthy group and increased in unhealthy group. Unhealthy group appeared to be decreased level of T-C, TG and LDL-C. In contrast, the unhealthy group revealed the increased level of HDL-C. These results demonstrate the effect of TRDM to elderly people. This effectiveness can be adapted for the protection and treatment of geriatics-related adult diseases such as diabetes, hypertension and hyperlipidemia.

We studied the postural response induced by plantar sole vibration with various frequencies(20, 60, 100Hz) and vibration zone(the anterior and posterior foot zone) of both soles during standing. Eight healthy young adults were exposed to 15s periods of plantar sole vibration while blindfolded. Body sway(COM, center of mass), the angle of neck, trunk, hip, knee, ankle and EMG of four lower limb muscles(tibialis anterior, lateral and medial gastrocnemial, soleus muscle) were recorded during 15s plantar sole vibration using 3D motion analysis system. Simulating each zone separately resulted in spatially oriented body tilts; oppositely directed backward and forward, respectively, the amplitude of which was proportional to the vibration frequency. EMG activity of lower limb muscles also varied according to the direction of the vibration zone and linearly according to the frequency. These findings led us to consider the plantar sole vibration as useful method of postural balance control and adjustment.

Tooth Positioner는 band를 제거한 후 가능한 빨리 장착시켜야 susceptible하며 무엇보다도 환자의 생리학적 jaw movement를 설정해서 제작해야 하고 적어도 hingeaxis relation은 찾아서 제작해야한다. Positioner의 장착시간은 하루에 $3\~4$시간의 active biting exercise와 수안시간동안 사용하게 한다. 처음 장착시에 가장 tight하고 이 tightness 는 치아가 요망되는 위치로 근접함에 따라서 점차 감소되고 이 tightness의 감소가 작용효과의 가장 좋은 지침이 되며 자는 하루 하루 그 변화를 느껴야 한다. Positioner가 느슨하게 적합되고 좋은 교합관계를 보이면 장착을 수안시간동안으로 제한시키거나 혹은 깨어 있을 동안 한 두시간 장착하게 한아. 대개 $3\~4$주 후에 predetermined pattern과 유사하게 되며, 일반적으로 장착 후 $8\~10$주 후에 더 장착할 것인가를 결정하고 필요성이 없다면 conventional retainer로 바꾸어 준다. Tooth Positioner는 기능적인 구호흡, thumb sucking, snoring을 해소시켜 줄 수 있으며 jaw relationship이나 overbite문제를 해결할 수 있다. 그리고 chair time을 감소시켜 줄 수 있으며 tissue tone을 자극해서 치아위치를 증진시키는데 끊임없이 작용한다. 그러나 제작에 많은 시간이 걸리고 치아를 배열하는 술자의 능력에 따라 치료효과가 많이 좌우되며 너무 bulky하므로 이물감이 커서 유용하게 장착할 수 있는 시간이 제한적이고 natural muscle balance에 대해 간헐적인 교정력을 가함으로써 치아를 loosening 시킬 수 있다. 이 장치물은 다른 removable appliance와 같이 환자의 협조가 무엇보다 중요하므로 환자에게 장착동기를 유발시켜 주는 것이 좋으며 True Blocked Nasal Airway가 있는 환자에게는 금기증이 된다.

This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.
