We hope this study would lead to protecting independent living for aged people in the aging society progressing in the world. Japanese life expectancy is 83.7 years old and the longest in the world. An aging rate is the highest at 26.0% in the world in 2014. The elderly ratio which was 12.1% in 1990 and increased to 26% in 2014. It is also the earliest pace of expansion in the world. There is the Long-Term Care Insurance System (Care Insurance) under the Long-Term Care Insurance Act (Insurance Act) to support this aged society. We investigated the situation of the English translation of the Care Insurance under the Insurance Act of Japan. We try to translate the untranslated part of it, "Care Degree" and introduced. We examined the Care Degree and the result of enforcement of the knee motivative exercise, which the outpatients are performing by themselves. We performed an evaluation of exercise with setting 15 subjects with their consent subjects at the medical facility by the therapist and rehabilitation collaborators. We analyzed the exercise value when they performed the motivative exercise individually. There was a big difference in the maximum range, the minimum range, time, and the average speed per second of the exercise under exercise for 300 seconds for every individual. We examined the correlation between exercise range and average speed, and the digitalized care degree. There were significant correlation as the maximum movement range (r = .702, p < .01), the minimum movement range (r = .608, p < .05), an average movement range (r = .745, p < .01), and average speed (r = .664, p < .01). We showed that the autonomous knee motivative exercise is an accommodated kinetic rehabilitation to the patient's physical strength due to correlating with the exercise value of the degree of care. We showed that they could implement under the therapist direction to do for 300 seconds without touching.
