[Purpose]We report a case concerning 5 months of left elbow and knee joint pain thought to be caused by repetitive use at work. Symptoms were improved successfully (checked by M-test) by a single acupuncture treatment.
[Case]We used acupuncture to treat a 50-year-old woman who visited our Acupuncture and Moxibustion Centerwith complaints of increasing elbow and knee joint pain in the left side. Since 4 months ago, her job involved frequent stair-climbing while carrying an 18-liter can of cooking oil. The soft tissues seemed to be damaged and caused pain due to the repeated lifting of heavy cans at work. Acu-points were decided by M-Test to check limitations of movement, which identified damaged regions and provided feedback for optimal treatment. According to the specific operations of the patient's work, we identified limited movements of left-elbow joint flexion-extension, left-shoulder joint extension, and left hip joint inner rotation and external gyration. These were regarded as target motions for the treatment. Her Visual Analog Scale (VAS) scores before treatment were 90 mm in the left elbow and 80 mm in the left knee. Despite only a single round of acupuncture treatment, the respective values dropped to 18 mm and 15 mm.
[Consideration and Conclusion]The limited movement identified by M-Test could expose the affected areas and help in treating the appropriate acu-points. Therefore, acupuncture using M-Test might improve painful motions of the body.

Endurance exercises, such as cycling or running, are useful for reducing arterial stiffness. However, individuals with a low physical fitness level, or patients suffering from leg diseases with pain, are unable to perform such moderate-intensity lower-limb exercises for long periods of time. The aim of this study was to evaluate the effects of acute cycling with Electrical muscle stimulation (EMS) on the brachial to ankle pulse wave velocity (ba-PWV). Ten healthy adult men performed 3 sessions, as follows of 20 min: cycling at 50% VO2max (C), cycling at an intensity of 50%VO2max subtracted from VO2 during EMS (LC), and cycling at the intensity of the LC trial while also being combined with EMS (LC+E). The ba-PWV was measured before and after each exercise. In addition, the femoral artery blood flow (BF) was measured in eight healthy adult men before and after exercise using an ultrasound imaging system. In the C and LC+E trials, the ba-PWV significantly decreased immediately after the exercise session, whereas the ba-PWV did not significantly change following the LC trial in any session. Compared with the baseline, the femoral artery BF values significantly increased after all trials. In the C and LC+E trials, the femoral artery BF was significantly greater than that in the LC trial. Acute endurance low-intensity cycling with EMS results in a reduction in the arterial stiffness which is similar to that with moderate-intensity exercise.
