[Purpose] The purpose of this study was to investigate the immediate effect of proprioceptive neuromuscular facilitation on muscle tone and muscle stiffness in stroke patients. [ Subjects and Methods] The subjects consisted of 15 patients with chronic stroke (stroke group) and 15 healthy persons (healthy group). We measured the effects of proprioceptive neuromuscular facilitation intervention on the lower extremity using a muscle tone measurement device; this detected changes in muscle tone and stiffness in the lower extremity muscles. [Results] Measurements taken before the intervention showed that, on average, the lower extremity muscles of the stroke group showed abnormally increased muscle tone and stiffness compared to the lower extremity muscles of the healthy group. After the intervention, the average muscle tone and stiffness in the lower extremity muscles of the stroke group decreased, but this change was insignificant, and the differences between the two groups were also insignificant. [Conclusion] Based on the findings of this study, we recommend proprioceptive neuromuscular facilitation treatment of both affected and non-affected sides to decrease the abnormally increased muscle tone and stiffness in the lower extremity muscles of chronic stroke patients.
[Purpose] This study aimed to examine the effects of a combined intervention consisting of massage therapy and transcutaneous electrical nerve stimulation on gastrocnemius muscle fatigue, assessing whether the intervention improved muscle tone, stiffness, and muscle contraction. [Subjects and Methods] The subjects were 20 healthy males in their 20s who were equally divided into a transcutaneous electrical nerve stimulation group and a combined therapy group that received a combination of massage therapy and transcutaneous electrical nerve stimulation. Muscle fatigue was triggered on the gastrocnemius muscle, and the effects of intervention method on muscle tone, stiffness, and muscle contraction were examined over time. [Results] Lateral and medial gastrocnemius muscle tone and stiffness significantly increased and gastrocnemius muscle contraction significantly decreased in each group immediately after fatigue was triggered on the gastrocnemius muscle. There was no difference in the effects of the two intervention methods over time. [Conclusion] This study verified that a combined therapy of massage therapy and transcutaneous electrical nerve stimulation was able to be used effectively in improving muscle tone, stiffness, muscle contraction, thereby reducing gastrocnemius muscle fatigue.
[Purpose] This study aimed to examine the effects of neuromuscular electrical stimulation on masticatory muscle activation in elderly stroke patients. [Subjects and Methods] The subjects included 20 elderly patients diagnosed with stroke and 10 healthy elderly individuals. The neuromuscular electrical stimulation group received stimulation on the masseter muscle in the affected side for 30 min each day, 3 times per week for 8 weeks. In all the subjects, surface electromyography was used to measure activity of the masseter and temporal muscles in both sides under resting and clenching conditions. [Results] In the neuromuscular electrical stimulation group, after the intervention, an increase in the activity of all of the masticatory muscles was observed during clenching, with a significant increase in the activity of the masseter muscle in the affected side. Significant differences between the groups were not observed after the interventions. [Conclusion] The results of this study suggest that application of neuromuscular electrical stimulation effectively improves muscle activity in elderly stroke patients during clenching, and that this technique can be applied particularly for the improvement of the clenching activity of the masseter muscle in the affected side.
[Purpose] The purpose of this case study was to identify the effects of joint mobilization using Kaltenborn-Evjenth orthopedic manual therapy (KEOMT) and proprioceptive neuromuscular facilitation (PNF) techniques on a patient with chronic low back pain (CLBP) and a lumbar transitional vertebra. [Methods] The intervention methods were joint mobilization using KEOMT and PNF techniques. The program consisted of 40-min sessions 3 days a week for 4 weeks. The spinal motion (thoracic and lumbar vertebrae), pain, and thickness of the multifidus were measured. [Results] The angle of spinal curvature increased, and the range of motions (ROMs) flexion and extension increased in the thoracic and lumbar vertebrae. The pain score as measured on a visual analogue scale (VAS) and the Oswestry disability index (ODI) score decreased. The thickness of the multifidus (L4) increased on the left and right sides. [Conclusion] These results suggest that joint mobilization using KEOMT and PNF techniques had a positive effect on the spinal motion, pain, and thickness of the multifidus of a patient with chronic low back pain and a lumbar transitional vertebra.
[Purpose] This study aimed to examine the immediate effects of diaphragm taping with breathing exercise on the tone and stiffness in the respiratory muscles of patient with stroke. [Subjects and Methods] A total of 28 subjects, 14 in the diaphragm taping with breathing exercise group and 14 in the breathing exercise group, were administered respective intervention methods. Subsequently, the muscle tone and stiffness in upper trapezius, scalene, external oblique abdominal and ractus abdominis muscle of both the respiratory muscles were measured. [Results] The comparison of respiratory muscles on the affected and non-affected sides in stroke patients showed statistically significant declines in the muscle tone and stiffness of all measured muscles but not in the stiffness of the external oblique abdominal muscle and rectus abdominis muscles. After intervention, the diaphragm taping with breathing exercise group exhibited statistically significant increases in the muscle tone of all measured muscles and in the stiffness of the upper trapezius and scalene muscles, and statistically significant declines in the saturation of peripheral oxygen. However, the breathing exercise group showed statistically significant increases only in the muscle tone of the upper trapezius and external oblique abdominal muscles. [Conclusion] This study demonstrated that diaphragm taping with breathing exercise had positive effects of immediately increasing the muscles tone and stiffness in the respiratory muscles.
