[์˜๋ฌธ] This study tested whether repeated measurement of median frequency (MDF)-related variables could express the muscle power changes during a 12-week DeLorme strengthening program, by using consecutive overlapping FFT (fast Fourier transformation) and integrated EMG (IEMG) from surface EMG data for isometric and isotonic exercise. To evaluate the effect of training, the following were recorded every 3 weeks for the elbow flexors and knee extensors of 5 healthy male volunteers: MVC, 1RM, limb circumference, and surface EMG during isometric MVC or isotonic contraction at 10RM load. From the EMG data, IEMG and variables from a regression analysis between MDF and time were obtained.MVC, 1RM, IEMG, and initial MDF increased linearly over the training period. The fatigue index and slope of the regression line increased temporarily until the 6th week and decreased thereafter. From these results, there appeared to be enhanced neural recruitment of fast twitch fibers in the first 6 weeks and continued enhancement in the recruitment and hypertrophy of fast twitch fibers, which led to increased fatigue resistance, over the last 6 weeks.Accordingly, the MDF and IEMG analysis technique could demonstrate the effect of the program detected significant changes in both isometric and isotonic contractions. EMG analysis methods can be used to estimate the electrophysiological and histological changes in skeletal muscles during a strengthening program.ope

[์˜๋ฌธ]Cortical reorganization and functional motor recovery were studied in subjects with chronic stroke paretic hand using functional magnetic resonance image (fMRI) before and after intensive treatment with an electromyography-triggered, neuromuscular stimulation (EMG-stim). Subjects were assigned randomly to either the EMG-stim group (n=7) or control group (n=7). The EMG-stim group received 2 sessions (30min/session) per day, five days per week over 10 weeks (100 sessions in total) on the extensor digitorum communis. The control group did not receive any treatment. The dependent variables consisted of the variables for hand function and for cortical activation. The hand function was measured by 1) the box and block test, 2) Fugl-Meyer assessment (FMA), 3) accuracy index and peak extension during metacarpophalangeal joint (MCP) tracking test, and 4) the delay in onset and offset and maximal strength during the isometric MCP joint extension. The cortical reorganization was measured by the laterality index using the fMRI. Functional brain images were collected with a 1.5 T magnetic resonance scanner. Predetermined regions of interest (ROIs) were the primary sensorimotor cortex (SMC), the premotor cortex (PMC), and the supplementary motor area (SMA).The EMG-stim group demonstrated significant improvement in all motor functional scores except for FMA, compared with the control group (p<0.05). Only SMC in the ROIs demonstrated a significant improvement compared with the control group (p<0.05). The SMC change was correlated significantly with the box and block test, tracking accuracy, peak extension, delay in EMG-offset and force-offset in change.We concluded that stroke patients receiving intensive EMG-stim showed an improvement of motor functions, and that these improvements were induced by brain reorganization from ipsilateral (or bilateral) activation to contralateral SMC activation.ope

    Provided are a driving simulator apparatus and a driver rehabilitation training method using the apparatus, the apparatus including: a display unit for displaying a preset simulation driving screen; a mode selecting unit via which a normal mode, an assist mode, or a resist mode is selected by a user; and a control unit for controlling to apply a driving force in a rotational direction of a steering wheel operated by a user when the assist mode is selected and to apply a reaction in an opposite direction to the rotational direction of the steering wheel operated by the user when the resist mode is selected. Accordingly, a driver with a degraded driving capability due to the aging or brain lesions may have effective driving rehabilitation training. In particular, besides the normal mode, the assist mode and the resist mode are added to conduct target tracking training to thereby improve visual-motor coordination of the user, thereby recovering the driving capability of a patient, which has degraded due to physical and cognitive damages. In addition, by configuring a program according to a state of a patient who needs driving rehabilitation, a recovery state of the patient according to continuous practicing may be estimated by comparing the same with an initial state of the patient. Also, the patient&apos;s fun or interests may be aroused so as to allow the patient to concentrate on practicing
