        The purpose of this study was to determine EMG biofeedback training effect on the muscle activities in 3 unilateral facial palsy patients along with multiple baseline design across subjects. The auditory feedback about facial muscles (orbicularis oris, orbicularis oculi, frontalis) was provided with each patient during facial exercise training. Electromyographic (EMG) activity during maximal voluntary contraction and maximal compound muscle action potential (CMAP) amplitude elected by supramaximal electrical stimulation on facial nerve of facial muscles were measured pre- and post- EMG biofeedback training to evaluate motor learning. EMG activity during maximal voluntary contraction was increased after EMG biofeedback training and CMAP amplitude elected by supramaximal electrical stimulation was not changed in all subjects. The results indicate that EMG biofeedback training is useful method to improve motor learning of facial excercise training in unilateral facial palsy patients.

        Despite research to treat delayed onset muscle soreness (DOMS), no effective treatment has been reported. The purpose of this study is to investigate the effect of a hold-relax technique and cryotherapy on DOMS. Thirty-three subjects were randomly assigned to one of three treatment groups: control, hold-relax technique, or hold-relax technique and cryotherapy. DOMS was induced in the non-dominant biceps muscle through repeated eccentric contractions. Resting elbow joint position, flexion and extension (universal goniometer), pain (Visual Analogue Scale; VAS), and WBC count (blood analysis) were measured one hour before DOMS was induced and 24, 48, and 72 hours after DOMS was induced. The data were analyzed by repeated measure of two-way ANOVA. The results of this study were summarized as follows: 1) While analysis showed no significant differences between groups in relation to a resting elbow joint position, there were significant differences over time, especially at 24, 48 hours after DOMS was induced compared with resting elbow joint position before DOMS was induced. 2) While analysis showed no significant differences between groups in relation to range of flexion, there were significant differences between range of flexion before DOMS was induced and range of flexion 72 hours after DOMS was induced. 3) There were no significant differences between groups or over time in relation to range of extension. 4) While analysis showed no significant differences between groups in relation to VAS, there were significant differences over time in different hours. 5) There were no significant differences between groups or over time in relation to WBC count. 6) There were no interactions between groups or over time in all variables. This results suggested that hold-relax technique and cryotherapy were not effective to reduce DOMS.

        This study was conducted to identify the effects of high-heel shoes on EMG activities of rectus femoris and biceps femoris in 28 healthy women. Subjects were composed of experimental group (wearing high-heel shoes) and control group (wearing low-heel shoes). Two groups participated in three conditions standing (bare foot wearing athletic shoes and 7.5 cm height shoes). In high-heel shoes condition, EMG activities of rectus femoris of control group were significantly lower than that of biceps femoris of experimental group, but EMG activities of both muscles of experimental group did not should significant difference. In bare foot standing condition, EMG activities of rectus femoris of experimental group were significantly lower than that of biceps femoris but EMG activities of both muscles of control group had no significant difference. These results showed that hamstring lengthening effects was produced when wearing high-heel shoes because the external knee extension moment was increased. In the short term, high-heel shoes effect on the increase of the biceps femoris activities by spindle reflex, but in the long term, the normal amplitude of the same muscle activities by Golgi tendon organ reflex.

        The purposes of this study were to ascertain differences of the sensory system, central processing system, effector system, and balance ability according to general characteristics (sex, fall experience, and age), and to identify the contributions of the sensory, central processing, and effector system to balance ability in 83 healthy elderly subjects. The subjects were elderly (over 60 years) who live in Wonju City. All subjects participated in six tests (position sense test, visual acuity, vestibular stepping test, Mini-Mental Status Exam-Korea, strength of dorsiflexors, and Berg Balance Test). Collected data were analyzed by the independent t-test, one-way ANOVA, and stepwise multiple regression. The results were as follows: 1. The results of the six tests according to sex showed that vestibular function was significantly better in women than in men. But visual acuity, cognitive function, strength of dorsiflexors, and balance ability were significantly better in men than in women (p<0.05). 2. There were no significant differences in position sense, visual acuity, vestibular function, cognitive function, strength of dorsiflexors, and balance ability between fallers and non-fallers (p>0.05). 3. However, the results of the six tests according to age (group A: 60-69 years, group B: 70-79 years, group C: 80-89 years) showed significant differences in five tests. In the Scheff test, position sense, visual acuity, and cognitive function showed significantly different results between in group A and group C: the strength of the dorsiflexors was significantly different between in group A and group B, and balance ability was significantly different between in group A and group C, and between in group B and group C (p<0.05). 4. Cognitive function and position sense were positively associated with balance ability. Their power of explanation regarding balance ability was 38% (p<0.05). These results suggest that cognitive function and position sense play an important role in balance ability. This would seem to suggest that programs for evaluation or improvement of elderly's balance ability in the elderly should consider cognitive function and position sense.

        The purpose of this study were to compare light touch, two-point discrimination, position sense, and static balance ability and to examine the relationship of static balance ability and different senses in those who are wearing various heights of high-heeled shoes. Each 29 women was classified two different heights (below 3 cm, above 7 cm) by experience in wearing shoes. A t-test was used to determine the differences between low- and high-heeled shoe in light touch, two-point discrimination, position sense, and static balance ability. Pearson correlation was used to examine the relationship of static balance ability to these sensation. The results were as follows: 1) No significant differences in average light touch, position sense between two groups were found(p>0.05). But significant differences in average two-point discrimination, static balance ability were found(p<0.05). 2) Static balance ability was not significantly correlated with light touch, position sense, two-point discrimination(p>0.05). The results suggest that long time experience in wearing high-heeled shoe may be caused local sensory change and decreased static balance ability. Even though, static balance ability was not significantly affected but correlated with two-point discrimination, position sense, and light touch in order.

        An A-B-A-C single subject research design was used to assess the effectiveness of transcutaneous electrical nerve stimulation(TENS) and inhibitive techniques on spasticity in a 10-year-old girl with cerebral palsy. Stimulation electrodes were placed over the sural nerve of the right leg. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. Inhibitive techniques including stretch, antagonist contraction, and weight bearing were used. The tonus of the leg muscle was measured by means of a surface-EMG biofeedback unit. Visual analysis of data indicate that the child showed clinically significant reduction of spasticity in passive ankle movement following 30 minutes of TENS and inhibitive techniques application, respectively. The effect of TENS on spasticity inhibition was similar to that of inhibitive techniques. This result suggests that for this child with cerebral palsy, the application of TENS to the sural nerve may induce short-term post-stimulation inhibitory effects on the spasticity of cerebral palsy. Replication of this study with a more complex single-subject design involving more subjects is recommended to confirm this result.

        The purpose of this study was to compare the effects of one proprioceptive neuromuscular facilitation technique and static stretching on calf muscle tightness. The subjects consist of 9 hemiplegics, and 9 quadriplegics. The eighteen subjects were randomly divided into 3 groups: prorioceptive neuromuscular facilitation(6 persons), static stretching(6 persons) and control(6 persons). Contract relax antagonist contract and static stretching techniques were applied continuously for twenty minutes each. Of the many proprioceptive neuromuscular facilitation techniques, only the contract relax antagonist contract technique was applied. The static stretching technique was applied with the subject placed in standing on a seventy degree inclined tilt table for twenty minutes. A wedge was placed under the feet to obtain maximum dorsiflexion. Wedge thickness varied with each subject. Results revealed: (1) a significant difference between the experimental and the control groups(p<0.05). (2) a significant difference between contract relax antagonist contract and static stretching groups(p<0.05). (3) At day five, the final increments were: contract relax antagonist contract , static stretching (meanstandard deviation).
