Evaluation of motion strategy during FRT is not generally included in physical assessment aiming at rehabilitation and promotion of good health. We believe that measuring only reach distance during FRT is insufficient for evaluating gait; therefore, examining motion strategy during FRT is also necessary. [Subjects] The subjects were 83 healthy university students (46 men and 37 women; range, 19-21 years), and 128 elderly persons (42 men and 86 women; range, 70-87 years). [Methods] We investigated and compared the motion strategy during FRT in both the young and elderly subjects and examined the influence of aging on motion strategy. [Results] Elderly persons used patterns of movement with ankle plantar flexion more often than the young persons. [Conclusion] The ankle plantar flexion pattern was dominant among the elderly subjects because the center of gravity in FRT was located within the base of support. We would like to use FRT as an index for fall prevention. To do that, we would need to devise a method to measure the ability to control the body in the situation in which center of gravity starts deviating from the base of support.
Abstract.[Purpose] Ability in activities of daily living of psychiatric patients is decreased because of postural control and voluntary movement disorders, and the quality of life of inpatients is also decreased. As preliminary research for evaluating standing balance of psychiatric patients, the purpose of this study was to investigate reach distance and movement strategy while subjects performed the functional reach test.[Subjects] Thirty-eight psychiatric patients and 38 healthy elderly control volunteers participated in this study.[Methods] Reach distance and movement strategy patterns were measured while subjects performed the functional reach test.[Results] The reach distance of the psychiatric patients was significantly shorter than that of the controls. The hip strategy was most often used by both patients and controls. Patients were more likely to select the ankle movement strategy than controls.[Conclusion] Based on the above findings, we speculate that the hip strategy is the ideal movement strategy for safely extending the reach distance of both psychiatric patients and controls. However, psychiatric patients were more likely to select the ankle movement strategy than controls.
Purpose: The F-wave shows the excitability of spinal nerve function. There is prior study that it is normal to appear the various F-waves. However, there is no provision for a method of judging whether or not it is the same waveform. The purpose of this study is to find objective evaluation in comparing F-wave waveform.Method: Present 5 trials of 30 F-wave to 3 people who are engaged in F-wave for many years. We compared the results of visually selected waveform and correlation coefficient (hereafter CC) calculated by personal computer.Results: There were 2 F-waves that 3 people checked, the highest value of CC was 0.99, the lowest value of CC was 0.95. There were 10 F-waves that 2 peoples checked, the highest value of CC was 1.00, the lowest value of CC was 0.71. From the above, consistency of 0.95 or more correlation coefficient was recognized, except for one case.
Conclusion:F-wave waveform analysis, criterion with a CC of 0.95 was made as a judgment of the same waveform. We think that waveform analysis become index for physical disability improvement in clinical scene and it will be an objective evaluation of influential physical therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
