The Effect of Muscle Facilitation Using Kinesio Taping on Walking and Balance of Stroke Patients

[Purpose] The aim of this study was to evaluate the changes in function and balance after Kinesio Taping application in stroke patients. [Subjects and Methods] Thirty subjects were randomly divided into an experimental group and control group. The experimental group was applied taping before therapeutic exercise, and the control group received only therapeutic exercise. Functional gait was measured using the straight line walking test, and dynamic balance ability was measured using the Berg Balance Scale. Walking velocity was measured with the 10u2005m walking test. [Results] There were statistically significant differences between the results of the straight line walking and 10u2005m walking tests in the pre-post analysis for the experimental group. There were a statistically significant difference in the Berg Balance Scale and 10u2005m walking test between the two groups. [Conclusion] Application of taping to the paralyzed parts of a stroke patient has a positive effect on improvement of typical asymmetric gait and walking speed.

Effects of Thoracic Mobilization and Manipulation on Function and Mental State in Chronic Lower Back Pain

[Purpose] The aim of this study was to evaluate the changes in function and mental state after thoracic mobilization and manipulation in patients with chronic lower back pain (LBP). [Subjects and Methods] Thirty-six subjects were randomly divided into mobilization group (group A), manipulation group (group B) and control group (group C). The Oswestry disability index (ODI) was used to measure the functional impairment of patients with LBP. A multiple spinal diagnosis was used to measure the range of motion (ROM) of vertebra segments. The Fear-avoidance beliefs questionnaire (FABQ) was used to investigate the mental state of LBP patients. [Results] Group A and group B were significantly different from group C in terms of the ODI. Between groups, there was no difference in ROM during trunk flexion. Group A and group B were also significantly different from the control group in extension ROM. The FABQ of group B was significantly different from that of group A. [Conclusion] Application of mobilization or manipulation to thoracic lumbar vertebrae has a positive effect on function, mental state, and ROM in patients with lower back pain.

The effect of non-elastic taping on balance and gait function in patients with stroke.

[Purpose] This study investigated the influence of exercise on balance ability and gait function in stroke patients after applying non-elastic tape, which can stabilize muscles and joints, to the lower extremities of the affected side. [Subjects and Methods] The subjects were 30 patients diagnosed with stroke. They were divided into an experimental group (n = 15) and a control group (n = 15). The experimental group performed mat and treadmill exercises three times a week for six weeks with non-elastic tape applied to the lower extremities of the affected side. The control group performed the same exercises but without taping. [Results] The intervention significantly improved Berg balance scale scores and timed up and go (TUG) test scores as well as reduced stance duration and stride duration in the experimental group. In the control group, statistically significant improvements were observed in TUG test scores. [Conclusion] Although some differences did not reach the level of statistical significance, the application of non-elastic tape stabilized the joints of the lower extremities, thereby increasing balance and reducing stance duration and one step duration, which resulted in a reduction of overall gait duration.

Effects of a Task-specific Exercise Program on Balance, Mobility, and Muscle Strength in the Elderly

[Purpose] The aim of this study was to investigate the effects of a task-specific exercise program based on motor learning on balance ability and strength of the lower extremity in the elderly with/without falling experiences. [Subjects and Methods] Individuals who had experiences of falling over 2 times within the past 6 months were included in the falling group. The task-specific exercise program consisted of 3 stages (weeks 1–2, 3–4, and 5–6) and was conducted according to the level of difficulty in this study. [Results] The scores of the Korean version of the Activities-Specific Balance Confidence Scale and Performance-Oriented Mobility Assessment were significantly changed in both the falling group and non-falling group after the task-specific exercise program. In comparisons between the falling group and non-falling group, there were also significant differences in the Korean version of the Activities-Specific Balance Confidence Scale and muscle strength of the semitendinosus and gastrocnemius. [Conclusion] The task-specific exercise program has a positive effect on balance ability and muscle strength related to falls in the elderly.

Edema and pain reduction using transcutaneous electrical nerve stimulation treatment

[Purpose] The purpose of this study was to investigate the impact on the edema and pain when applying transcutaneous electrical nerve stimulation. [Subjects and Methods] Eleven patients who were diagnosed with lymphedema were selected as the subjects of the study. The experimental group received transcutaneous electrical nerve stimulation treatment on edema regions three times per week for four weeks. Surface tape measurement was used to measure changes in lower extremity edema. Pain intensity was measured using the visual analog scale. [Results] The edema decrements in the experimental group were significantly larger than those in the control group. The pain decrements in the experimental group were significantly larger than those in the control group. [Conclusion] In conclusion, application of transcutaneous electrical nerve stimulation was confirmed to be effective in reducing edema and pain.

Effects of physical exercise on the functional recovery of rat hindlimbs with impairments of the sciatic nerve as assessed by 2D video analysis.

[Purpose] The purpose of this study was to investigate the effects of treadmill training on functional recovery by analyzing the ankle joint as well as the knee and hip joints with 2D video analysis during gait by rats with sciatic nerve injury. [Subjects and Methods] Twenty-four male Sprague-Dawley rats were used in this study. The sham group (SG) received only a sham operation without any sciatic injury; the training group (TG) performed treadmill training for 4 weeks after sciatic injury; and the control group (CG) wasn’t provided with any therapeutic intervention after sciatic injury. [Results] The ankle, knee, and hip ROM of TG and CG during the initial, mid stance, and toe-off phases of gait at post-test were significantly different from SG. [Conclusion] Physical exercise, like treadmill training, is beneficial for the improvement of the ankle, knee and hip joints of rats with crushed sciatic nerve injury.

Nerve growth factor expression in stroke induced rats after shock wave

[Purpose] This study investigates effects of extracorporeal shock wave therapy on nerve growth factor expression in stroke in rats. [Subjects and Methods] Sixteen eight-week-old Sprague-Dawley rats were used and randomly divided into two groups: an experimental group, a control group. The experimental group received extracorporeal shock wave therapy after the stroke. The spinal cord encompassing the lumbar 4-lumbar 5 level was then removed for Western blot analysis. [Results] There was a significant difference in nerve growth factor expression between the groups after the impairment. [Conclusion] Application of extracorporeal shock wave therapy increased the expression of nerve growth factor and nerve growth factor postulated to promote nerve growth factor upregulation through formation of a microenvironment at the spinal cord level related to the injured area.

Effects of Kinesio taping and Mcconnell taping on balance and walking speed of hemiplegia patients

[Purpose] The aim of this study was to evaluate the overlap effect of the PNF following the application of Kinesio taping and the McConnell taping, and also the impact of the taping application method on the balance and walking speed of the patients with stroke. [Subjects and Methods] Thirty-six patients who were diagnosed with hemiplegia due to stroke were selected as subjects of this study. They were randomly and evenly divided into experiment group 1 (Kinesio taping group), experiment group 2 (McConnell taping group), and the control group; each group had 12 patients. [Results] The Berg balance scale (BBS) was used to evaluate balance, and the ability in this study. A 10u2005m walking test (10MWT) was performed to measure the walking speed. Experiment group 1 showed a statistically significant improvement in balance and walking speed compared to experiment group 2, and the control group in week 4 and week 8. [Conclusion] Application of Kinesio taping had a more beneficial effect on the balance and walking speed than joint-fixation taping of the patients with stroke.

The effects of stabilization exercise with an oral assistive device on pain and functionality of low back pain patients

[Purpose] This study examined low back pain patients’ decrease in pain and improvement in functionality after performance of a lumbar stabilization exercise using an oral assistive device, which can replace a lumbar assistive device. [Subjects and Methods] The experimental group (n=12) conducted a stabilization exercise using an oral assistive device after conventional physical therapy. The control group (n=12) received conventional physical therapy. In order to objectively measure pain in this study, a visual analogue scale (VAS) was used. In order to evaluate the subjects’ functional aspects while living with low back pain, the Oswestry Disability Index (ODI) was used. [Results] There were statistically significant improvements in the comparison of the VAS and ODI of the experimental group and the control group. The experimental group’s VAS and ODI significantly improved after the intervention compared to the control group. [Conclusion] The stabilization exercise using the assistive device after conventional physical therapy in the rehabilitation of low back pain patients reduced subjects’ pain and increased their functional activities.

Analysis of muscle activations in lower extremities muscles at various angles of ankle flexion using wedges during static squat exercise.

[Purpose] This study aimed to investigate changes in activation of the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius muscles during one-legged squats performed at various angles of ankle flexion. With the use of wedges, the muscles were activated at different angles of ankle flexion angles to establish the appropriate posture necessary for muscle strengthening and rehabilitation. [Subjects and Methods] Healthy adults aged 20–40u2005years were recruited from Good Morning Hospital in Ulsan City. Of the 22 participants, two dropped out during the tests, leaving a final sample of 20 participants. The wedges were 100u2005mm wide and 200u2005mm long and had inclinations of 10°, 30°, and 50°. EMG Analyzer software was used to measure muscle activation. [Results] A significant difference in the activation of the rectus femoris muscle at various angles of ankle flexion was seen. The gastrocnemius muscle exhibited significant differences in activation among the 0°–30°, 0°–50°, and 10°–50° inclinations. [Conclusion] Wedge-assisted muscle activation under different ankle flexion angles can be introduced as an effective exercise option under clinical conditions.
