[Objective] The purpose of this study is to examine the effects of press tack needles (PTNs) on subjective assessment of symptoms such as heaviness, stiffness and lassitude in the lower limbs during walking, or in everyday life. Sham PTNs are used for the purpose of comparison.
[Methods] The subject is a male in his seventies who has a daily routine of walking 10,000 steps; experiences heaviness, stiffness and lassitude in his lower limbs; and has spinal or internal disease. Intervention: PTNs or sham PTNs are randomly chosen and worn on the subject's body for two days. The subject fills out a questionnaire regarding subjective assessment of symptom relief in his lower limbs during the following three time periods; in advance of the use of PTN, in the evening during the use of PTN, and the following evening. PTNs are applied to a total of 10 sites around both sides of his lower limbs depending on symptomatic or tender areas. Assessment: A questionnaire, in which a Visual Analog Scale (VAS) is introduced, is filled out three times per trial, that is, thirty records from ten trials are finally kept. Differences can be seen in the result answered the following evening. The results regarding the use of PTNs and the results regarding the use of sham PTN are analyzed respectively by randomization test (R test).
[Result] Significant difference was shown in the heaviness of the lower limbs for both the PTN and sham in the evening of the next day (P < 0.05). Significant difference was shown in the stiffness of the lower limbs for both the PTN and sham in the evening of the next day (P < 0.05).
[Conclusion] A PTN is attached for two days when there is a feeling in the lower limbs of heaviness and stiffness, even with spinal disease, liver disease or varicose veins in the lower extremities. It is suggested that PTNs are effective in decrease of symptoms.
