Objective: The rehabilitation protocols for functional recovery have been emphasized after total knee arthroplasty, and Pilates is in the spotlight as a safe and easily modified exercise method. The purpose of this study was to investigate the effects of mat Pilates exercise on lower extremity function, postural balance, and walking in the individuals with total knee arthroplasty. Design: One group pretest-posttest design. Methods: Eighteen older women with unilateral total knee arthroplasty was recruited in the study. The subjects were evaluated on lower extremity function, postural balance, and walking before and after mat Pilates exercise. All subject performed one hour mat Pilates exercise, 3 times a week for 8 weeks. Mat Pilates exercises were focused on core stability and lower extremity strengthening and, more dynamic movements were added to increase the difficulty of movements every two weeks. The lower extremity function was measured using the Western Ontario and McMaster Osteoarthritis Index (WOMAC), knee joint position sense, and five times sit-to-stand test. Postural balance was assessed by single leg stance test, functional reach test, and timed up and go test. Walking was measured by OptoGait system to temporospatial parameter. Results: The lower extremity function, postural balance, and walking were significantly improved after mat Pilates exercise, except for five times sit-to-stand test (p<0.05). Conclusions: This study demonstrated that the mat Pilates exercise was a useful method to improve lower extremity function, postural balance, and walking in the older women with unilateral total knee arthroplasty.

The purpose of this study was to assess the effects of lower extremity resistance training using elastic bands on balance in elderly people. Eight elderly persons each were randomly assigned to a test group(resistance exercise group, REG) or a control group(CG). FRT and TUG test were used to compare balance before and after exercise. Exercise programs were implemented three times a week for 40 minutes for nine weeks. They did warm-up exercise for 5 minutes and then lower extremity resistance exercise using elastic bands for 30 minutes. And then they did cool-down exercise for 5 minutes. TUG and FRT significantly decreased but in the control group it did not significantly decrease. In comparison between the groups, TUG and FRT significantly reduced in the resistance exercise group compared to the control group. Lower extremity resistance training using elastic bands performed by elderly persons are considered to be effective in improving balance.

Objective : This study aims to examine how lumbar stabilization exercise and resistive exercise affect lumbar and lower extremity muscular strength of the aged. Method : Randomly selected 15 female senior citizens aged 65 or older at S, Y, and J senior citizens' center located in D city who meet the requirements for the study were divided into a resistive exercise group of 7 and a stabilization exercise group of 8 for which 60-minute-exercise sessions were administered three times a week for 12 weeks. Measuring lumbar and lower extremity muscular strength was measured six weeks and 12 weeks after exercise, respectively. Results : First, both resistive exercises and stabilization exercises are effective to improve lumbar muscular strength. Second, resistive exercise is effective to improve flexural muscle strength as well as lower extremity muscular strength, and stabilization exercise is effective for both flexion and extensor muscle strength. Conclusion : The 12 week lumbar stabilization exercise program appeared to be effective to improve lumbar and lower extremity muscular strength of the aged. This indicates that applying this program to identify and prevent frequent risk factors of falling can lead to the prevention of secondary problem factors of falling accidents.

PURPOSE: The purpose of the study was to determine the effects of close kinetic chain resistant exercise of lower extremity on the gait with stroke patients. METHODS: The subjects were 50 patients who were diagnosed with cerebrovascular accident. They were randomly assigned either to a close kinetic chain resistant exercise of lower extremity group (study group)(n=25) or open kinetic chain resistant exercise of lower extremity exercise group (control group)(n=25). Gait abilities were measured by using Timed Up & Go (TUG) test, Functional Gait Assessment (FGA) and spatio-temporal gait variable that were velocity, cadence, stride length, double limb support by 3 axises wireless accelerometer and sway angle of center of mass by same instrument. RESULTS: Study group and control group before and after the intervention there were significantly difference in TUG, FGA, spatio-temporal gait variables and sway angle of center of mass (p<.05). There were significantly different between study group and control group for all variables at post-exercise. CONCLUSION: When all is said and done it is expected to be used as a method for the treatment and prevention in the process of rehabilitation of patients with stroke. In its final analysis when applying resistant exercise of lower extremity to stroke patients' gait, close kinetic chain is more effective than open kinetic chain.
