가설 설정
- The researcher considers that the treatment of TENS has an effect on the recovery of muscle fatigue because it can regulate and relieve the pain, stimulating sensory nerve electrically and it can also alleviate the muscle pain by fatigue owing to its effect of slight fever, massage effect and its effect on relieving muscle contracture.
제안 방법
- Accordingly, this research aimed to investigate how effectively the transcutaneous electrical nerve stimulation(TENS), self stretching and Functional Massage help human body to recover from the muscle fatigue, caused by exercise and also intended to look into which one shows the best effects in the same time duration of treatment, if the 3 methods shows a discrepancy in terms of recovery level.
- and normal distribution for all the data was verified by K-S test(Kolomogorov-Smirnov Test). And descriptive analysis was performed to work out the general features of the subjects.
- In this research, the researcher applied the treatments of TENS, functional massage and selfstretching to the quadriceps femoris, of which muscle fatigue was caused by isotonic exercise. And the researcher looked into the change of maximal voluntary contraction after these applications and intended to investigate which method of treatment worked most effectively for the recovery of muscle strength. Primus RS(BTE/USA) was adopted for isotonic exercise.
- Having fixed the tool at 70° of the bending angle of knee joint and linking the tool with the leg, ascertained to be non dominant, after having the subject seated on Primus RS and having the thoracic cage and femoral region of subject be fixed by Velcro fastener, the researcher had the subject conduct the extension exercise of knee joint.
- In this research, the researcher applied the treatments of TENS, functional massage and selfstretching to the quadriceps femoris, of which muscle fatigue was caused by isotonic exercise. And the researcher looked into the change of maximal voluntary contraction after these applications and intended to investigate which method of treatment worked most effectively for the recovery of muscle strength.
- In this research, the researcher has aroused the muscle fatigue using the program for isotonic exercise of Primus RS equipment and looked into the recovery aspect of muscle fatigue, based upon the measurement of MVIC after treatment. Two ways are to be used to determine whether the fatigue has occurred.
- In this research, the researcher has measured the fatigue, having instructed the subject to maintain the extension power as long as possible at the level of 50 % of knee joint's maximum contraction(16).
- The researcher has measured maximum voluntary isometric contraction(MVIC) upon accomplishing the isometric contraction for 3 seconds, three times, and 2 minutes' relaxation was allowed per a contraction for 3 seconds to eliminate the influence of fatigue.
- 45 healthy male and female students, attending the department of physical therapy at N university in Cheonan City were chosen as the subject and this research was conducted. The subjects were randomly assigned to the TENS(transcutaneous electrical nerve stimulation)group, self stretching group and functional massage group and the number of members of each group was 15 equally, non dominant legs of the research subjects were chosen for this research in order to compare the changes in maximum muscle strength, for the effects of exercise and treatment might become less as the subjects are all in their early 20s. The purpose and method of research were briefed to the subjects, prior to the commencement of experiment and all the subjects consented to the experiment voluntarily.
- This research was conducted to investigate the difference among 3 treatment methods in terms of the ability to regain the maximum muscle strength, after the researcher had aroused the muscle fatigue by isotonic exercise. 45 healthy adults in their 20s were selected as the subjects and the maximum muscle strength was measured before arousing muscle fatigue, after arousing muscle fatigue by isotonic exercise and after the application of treatment for 20 minutes, respectively.
- The experimenter flexed the subject's knee joint with one hand, while pressing down the subject's leg on the part of quadriceps femoris with his body weight. Treatment was applied to the part of vastus medialis, vastus lateralis and rectus femoris as the electric stimulation group and only one experimenter was allowed to conduct massage to make the experiment coherent.
- Having fixed the tool at 70° of the bending angle of knee joint and linking the tool with the leg, ascertained to be non dominant, after having the subject seated on Primus RS and having the thoracic cage and femoral region of subject be fixed by Velcro fastener, the researcher had the subject conduct the extension exercise of knee joint. Upon having each treatment group undergo the respective treatment of TENS, functional massage and self stretching for the fatigued quadriceps femoris, the research was executed by means of the following methods in order to investigate the change of muscle contraction.

- The equipment of Automote101(3NS/Korea) was used for TENS. This equipment, of which the pulse width is 50㎲ and the adjustable pulse rate ranges from 1Hz to 1000Hz has no hazardous effect on human body.
- Total 45 subjects who were divided into 3 treatment groups of equal 15 subjects, participated in this experiment without any dropout. The average age of TENS group was 20.
데이터처리
- In order to compare the differences between groups per period, Two way ANOVA was used and Paired ttest was used in order to make a comparison before and after the respective treatment. The significant level was set at .
이론/모형
- 0. and normal distribution for all the data was verified by K-S test(Kolomogorov-Smirnov Test). And descriptive analysis was performed to work out the general features of the subjects.
성능/효과
- 1. The MVIC after treatment was found to be significantly higher than the MVIC before the treatment with all treatment methods after the occurrence of muscle fatigue(p<.05).
- 2. No significant difference was found among the respective treatments in terms of the recovery results(p>.05).
- In this research, the MVIC after the treatment of TENS turned out to be significantly improved, compared to the MVIC before the treatment. It seems to mean that the treatment of TENS had an effect on the recovery of muscle fatigue.
- Putting above results together, the researcher made a conclusion that all the treatments of TENS, selfstretching and functional massage have positive effects on the recovery of fatigue, though no difference among 3 methods were found in terms of the extent of recovery.
- The researcher has measured maximum voluntary isometric contraction(MVIC) upon accomplishing the isometric contraction for 3 seconds, three times, and 2 minutes' relaxation was allowed per a contraction for 3 seconds to eliminate the influence of fatigue. The measurement was repeated 3 times and the average of measurement values was chosen as MVIC in case of no outlier. If we find an outlier, we adopt the average of the remaining 2 measurement values as MVIC, upon deleting the outlier.
후속연구
- Also, it is suggested a research should be executed, considering various significant factors, in order to prove that the treatments of TENS, functional massage and self stretching have an effect on the recovery of maximum muscle strength.
