Purpose : The purpose of this study is to investigate the effect of strengthening program for improving the muscle strength and body function in rehabilitation of patients with stroke Methods : We found the 15 precedent studies at online portal site of "Korea education and Research information service" and found 5 precedent studies at "Pubmed". We analyzed and describe the total 19 studies involving national and international research. Results : The strengthening exercise was adapted to lower extremities and trunk muscle of participants and the isokinetic (concentric and eccentric) exercise was most of exercise type and then manual isometric exercise, functional activities, progressive task oriented resistance exercise, PNF pattern exercise was following. The studies reported that the strengthening program increased target muscle strength and improved balance capacity and walking function for the participants positively. Conclusion : Conclusionally the several strengthening program can be the intervention to increase the muscle strength without increasing spasticity for patients with stroke. We think that the strengthening of lower extremities an improve balance capacity and walking ability and it can use the intervention to change the quality of life in patients with stroke. More than 3weeks strength program might be effectiveness, in case of acute patients with stroke, the improving of muscle strength is available but need to study for improving balance and walking capacity more in the future.

The purpose of this study was to observe the change of circumference, volume and strength of normal and operated lower extremities on 3rd, 7th, 10th, and 14th days of postoperation following THRA compared with their condition on preoperation day. Subjects consisted of 13 male and 7 female Patients operated with THRA between the age of 20 and 69 years with a mean age of 38.55(SD=15.1). Circumference of upper and lower leg was measured by tape, leg volume was determined according to formula (Moor & Thornton, 1987) with measurement of 8 circumferences of leg. Leg strength was measured by pressing the center of digital health meter in supine position. The results can be summarized as follows : 1. Circumference of operated thigh decreased significantly at 14 following THRA compared with preoperative value, while that of normal thigh decreased significantly at day 3, 7, 10 and 14 after THRA compared with preoperative value. 2. Circumference of midcalf in both operated and normal limb decreased significantly at day 3, 7, 10 and 14 following THRA compared with preoperative value. 3. Leg volume of operated lower limb decreased significantly at 10, 14 following THRA compared with preoperative value, while that of normal limb decreased significantly at day 7 & 10 after THRA compared with preoperative value.4. Leg strength of operated limb decreased significantly at day 3, 7, 10, 14 following THRA compared with preoperative value. No significant difference of normal leg strength was shown following THRA. 5. Circumference of midcalf differed significantly at day 14 after THRA between normal and operated extremity. From these results, it can be suggested that a decreased activity after THRA caused muscle atrophies in normal and operated extremity.

PURPOSE: Application of an oscillating program for the lower extremities is an effective training method for increasing muscle strength. However, no oscillatory program has yet been identified to confirm the effectiveness of oscillation for balance ability and maximum muscle strength. We investigated the effects of an 8-week vibration exercise program on the maximum muscle strength and balance of the lower extremities. METHODS: Research subjects participating in the study were 22 male and female college students with no past history of diseases of the nervous or musculoskeletal systems. All subjects were randomly divided into two groups and performed their assigned experimental treatment 3 times a week over a period of 20 min for 8 weeks. Maximum strength of the quadriceps extension, flexion, and balance ability were measured using Biodex System 4 and Biodex balance systems. RESULTS: The 8-week oscillation program resulted in a significant increase in quadriceps extension and flexion strength in both male and female participants (p<.05). The balance ability also showed a significant improvement after the oscillation program (p<.05). The balance value was higher for male 17% than for female 21% (p<.05) participants. CONCLUSION: An 8-week oscillation program led to an increase in the strength of knee flexion and extension. The balance ability also improved significantly. This positive effect on balance ability was higher in female than in male subjects.

In order to investigate the effects of a decreased activity on skinfold thickness, circumference and muscle strength of the extremities during the recovery period following heart surgery, skinfold thickness, circumference and muscle strength of the extremities were measured on days 0, 3, 6, and 9 following the surgery, and compared with those on the arrival day of intensive care unit. Skinfold thickness was measured using a skinfold caliper(Saehan Cor., Korea), circumference of the limbs were measured with a tape measure, upper extremity strength was determined using the Takei grip dynamometer and lower extremity strength was measured by pressing the flatfoot on an electronic digital health meter while tying on a bed. Results from this study were thus : 1. Skinfold thickness of triceps, quadriceps and gastrocnemius muscle on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. 2. Circumference of midupperarm and midthigh on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. Circumference of midcalf on days 3, 6 following the heart surgery was not significantly different from that of on the day of operation, while that of midcalf on day 9 following the surgery decreased significantly compared with that of on the day of operation. 3. Muscle strength of the upper extremity was not significantly different from that of on the day of operation, while that of the lower extremity on day 9 following the surgery decreased significantly compared with that of on the day of operation. From these results, it may be concluded that circumference and muscle strength of lower extremity can be decreased due to the postoperative inactivity following heart surgery in congenital heart disease children.

Objective: The aim of this study is to test the effects of elastic band exercise accompanied by Swiss ball exercise on lower limb muscle strength, balance and pain in middle-aged women with osteoarthritis. Design: A randomized controlled trial. Methods: Thirty-five participants were randomly assigned to the experimental group (n=18), which performed elastic band exercise combined with Swiss ball exercise, and the control group (n=17), which performed elastic band exercise only. Both groups did a 30-minute session of exercise three times a week for eight weeks and were assessed for lower extremity muscle strength, static and dynamic balance, and pain levels before the first therapy session. All participating patients underwent outcome assessment after eight weeks of therapy without any additional treatment. Results: The experimental group made a significant increase in muscle strength of the lower extremities, static and dynamic balance ability, and pain level (p<0.05). The control group made a significant improvement in lower limb muscle strength, dynamic balance ability and pain level (p<0.05) with no such improvement in static balance ability. The exercise group made a significant increase in static and dynamic balance ability and pain level compared to the control group (p<0.05). Conclusions: These results demonstrated that both Swiss ball exercise and elastic band exercise were effective for middle-aged women with osteoarthritis and found that elastic band exercise combined with Swiss ball exercise produced more significant effects on their balance and pain.

Grip strength provides a quick and objective index of the functional integrity of the upper extremities. It is widely used as an assessment measure in physical and rehabilitation medicine. In this study, maximum voluntary grip strength of 20 college students wearing 5 different gloves were measured using Jamar hand dynamometer. The results show that maximum voluntary grip strength was generally reduced when wearing gloves as compared to bare-handed. More specifically, the grip strength was highest when wearing PVC coated glove or bare-handed and getting lowered as wrist band, rubber, leather, and cotton glove in these order. Depending on the measuring posture of grip strength, shoulder height with arm extended forward was higher than the elbow was flexed 90 degree. Moreover, subjects' demographic factors and hand dimensions were not closely related to the grip strength. It is thus recommended that the proper glove should be provided to reduce the negative consequences including dropping a tool, poorer control of a tool. lower quality work, and increased muscle fatigue and in turn to increase the user safety and satisfaction.
