Background: The gastrocnemius (GCM) is one of the lower extremity muscles that tend to tighten easily. GCM tightness results in limited ankle dorsi-flexion (DF), especially when the knee joint is fully extended. Joint flexibility is determined by the morphological and physiological characteristics of joints, muscles, tendons, and ligaments. Impaired joint flexibility can be attributed to increased susceptibility to muscle injury. High-frequency diathermy is clinically used to reduce pain and muscle tightness and to improve limited range of motion. Objects: This study aimed to investigate the immediate effects of high-frequency therapy in subjects with GCM tightness. Methods: The study was designed as a one-group before-after trial. The subjects included 28 volunteers with GCM tightness (an active ankle DF angle of less than 12°) without any known neurological and musculoskeletal pathologies in the ankle and calf areas. WINBACK Transfer Electrode Capacitive and Resistive Therapy equipment was used to apply high-frequency therapy to the subjects' GCMs for 10-15 minutes. The pennation angle and the fascicle length of the GCM were measured using ultrasonography. The flexibility of the ankle joint, peak torque to the passive ankle DF (Biodex), and soft tissue stiffness (MyotonPRO) were also measured. Results: The pennation angle was significantly decreased following the treatment; however, no significant difference in the fascicle length was found (p < 0.05). The flexibility was significantly increased and both the passive peak torque to passive ankle DF and the soft tissue stiffness significantly decreased (p < 0.05). Conclusion: High-frequency therapy is immediately effective for improving the muscle's architectural properties and functional factors in subjects with GCM tightness. Further longitudinal clinical studies are required to investigate the long-term effects of high-frequency therapy on subjects with GCM tightness from various causes.

The dynamic responses of human standing postural control were investigated when subjects were exposed to long-term horizontal vibration. It was hypothesized that the motion of standing posture complexity mainly occurs in the mid-sagittal plane. The motor-driven support platform was designed as a source of vibration. The AC Servo-controlled motors produced anterior/posterior (AP) motion. The platform acceleration and the trunk angular velocity were used as the input and the output of the system, respectively. A method was proposed to identify the complexity of the standing posture dynamics. That is, during AP platform motion, the subject's knee, hip and neck were tightly constrained by fixing assembly, so the lower extremity, trunk and head of the subject's body were individually immovable. Through this method, it was assumed that the ankle joint rotation mainly contributed to maintaining their body balance. Four subjects took part in this study. During the experiment, the random vibration was generated at a magnitude of $0.44m/s^2$, and the duration of each trial was 40 seconds. Measured data were estimated by the coherence function and the frequency response function for analyzing the dynamic behavior of standing control over a frequency range from 0.2 to 3 Hz. Significant coherence values were found above 0.5 Hz. The estimation of frequency response function revealed the dominant resonance frequencies between 0.60 Hz and 0.68 Hz. On the basis of our results illustrated here, the linear model of standing postural control was further concluded.

This paper proposed the sizing system for womens lower clothes. The sizing system was classified according to 4 body types and 5 age groups. The size intervals of waist girth, hip girth, stature, and slacks length were 3cm, 4cm, 8cm, and 5cm respectively. Frequency distribution analyzed with waist girth, hip girth, and stature showed that the most frequent sizes were 86-100-158 in the fattest-medium length H type, 77-92-158 in the fat-short M type, 68-92-158 in the balanced-long A type, and 65-88-158 in the balanced-medium length A type. The number of the sizes for lower clothes, which had frequencies more than 4∼5%, was 33 and each size was presented with slacks length, skirt length, thigh girth, and knee girth. Also frequency distribution analyzed with waist girth, hip girth, and slacks length showed that the most frequent sizes were 86-100-90 in the fattest-medium length H type, 74-96-90 in the fat-short M type, 68-92-90 in the balanced-long A type, and 65-88-90 in the balanced-medium length A type. The sizing system classified by age group had 21 cases in the early twenties, 21 cases in the late twenties, 18 cases in the early thirties, 16 cases in the late thirties, and 8 cases in the forties. This result will contribute to clothing fitness and efficient production.

Objectives : This study is aimed to evaluate and objectify the therapeutic effect of moxibustion on muscle fatigue recovery. Methods : To evaluate the therapeutic effect on the muscle fatigue recovery, we compared the fatigue recovery of two groups (non-stimulation group and moxibustion group) by analyzing the EMG and peak torque after strenuous knee exercise of isokinetic contraction. Results : The median frequency (MF) of the moxibustion group was recovered faster than that of the non-stimulation group. However, the peak torques of both groups were not restored until after 20 minutes. Nevertheless, the moxibustion group's peak torque was regained higher than that of the non-stimulation group. Conclusions : We confirmed the therapeutic effect of moxibustion and found that the moxibustion can used as prevention method for musculoskeletal disease.

We studied the postural response induced by plantar sole vibration with various frequencies(20, 60, 100Hz) and vibration zone(the anterior and posterior foot zone) of both soles during standing. Eight healthy young adults were exposed to 15s periods of plantar sole vibration while blindfolded. Body sway(COM, center of mass), the angle of neck, trunk, hip, knee, ankle and EMG of four lower limb muscles(tibialis anterior, lateral and medial gastrocnemial, soleus muscle) were recorded during 15s plantar sole vibration using 3D motion analysis system. Simulating each zone separately resulted in spatially oriented body tilts; oppositely directed backward and forward, respectively, the amplitude of which was proportional to the vibration frequency. EMG activity of lower limb muscles also varied according to the direction of the vibration zone and linearly according to the frequency. These findings led us to consider the plantar sole vibration as useful method of postural balance control and adjustment.

Purpose: Patient-controlled epidural analgesia (PCEA) is an effective method for controlling post surgical pain. However, it is associated with adverse drug reactions such as nausea and vomiting. In this, study we tested the effects of Nei-Guan (P6) acupressure on PCEA-associated nausea, vomiting, and pain in geriatric patients after total knee replacement arthroplasty (TKRA). Methods: Ninety-nine patients who had TKRA for the first time were randomly assigned to either, experiment group (n=50) or control groups (n=49). All patients received PCEA immediately after surgery, but acupressure on Nei-Guan (P6) point was applied to experiment group only. Ten minutes of finger acupressure on Nei-Guan (P6) acupressure point was applied twice with 15 minute-interval in the experiment group. The incidence of nausea, vomiting, and retching as well as pain intensity were assessed at 12 and 24 hours after surgery. Nausea, and vomiting were assessed by Index of Nausea, Vomiting and Retching (INVR) questionnaire. Pain intensity was measured with frequency of analgesics. Results: Vomiting both was significantly different between two groups at 12 hours (t=-2.18, p=0.03) and 24 hours (t=-2.64, p=0.01) after surgery. Total scores of nausea, vomiting and retching in experimental group was significantly lower than control group 24hours after surgery (t=-2.18, p=0.03). However, pain was not different between two groups. Conclusion: Nei-Guan (P6) acupressure may be considered as an effective nursing intervention to decrease PCEA-associated nausea and vomiting in older patients after TKRA.
