PURPOSE: The purpose of this study is to examine the effect of proprioceptive neuromuscular facilitation (PNF) neck flexion exercise and the Shaker exercises on the activity of the suprahyoid muscles in chronic stroke patients with dysphagia and to show what exercise methods are effective for swallowing rehabilitation. METHODS: This study was conducted at F hospital in Daegu from August 2014 to February 2017 with 60 participants who understood the purpose of the study and desired to participate. The 60 participants were randomly divided into an experimental group (PNF neck flexion exercise) (n=30) and a control group (Shaker exercise) (n=30). PNF neck flexion exercise was performed in the experimental group and the Shaker exercise was performed in the control group for 30 minutes, 5 times a week for 6 weeks. The activity of the suprahyoid muscles was measured before and after treatment. RESULTS: Both the experimental group and the control group showed a statistically significant change in the activity of the suprahyoid muscles before and after the treatment. The changes were also statistically significant when compared by group. CONCLUSION: In conclusion, PNF neck flexion exercise should be used in addition to Shaker exercise when rehabilitating a patient with a swallowing disability.

Dawoon Jeong,Gak Hwangbo 국제물리치료연구학회 2020 Journal of International Academy of Physical Ther Vol.11 No.1

Background: Early rehabilitation after partial meniscectomy is important to recover the balance of the vastus medialis oblique and vastus lateralis and prevent pathological problems in the lower extremities and the whole body. Objective: To compare muscle activations for patients after partial meniscectomy. Design: Dual-group Pretest-Posttest Design from the Quasi-Experimental Research. Methods: Twenty participants after partial meniscectomy were recruited and were randomly divided into a Q-setting sensorimotor training group (QSMTG) and Q-setting exercise group (QSEG). Muscle activity of the vastus medialis oblique and vastus lateralis was measured before and after intervention. Results: In the two groups, the vastus medialis oblique and vastus lateralis activations increased significantly (P<.05). The Q-setting sensorimotor training group showed more increases than the Q-setting exercise group, and there were significant differences between the groups (P<.05). The activation ratio of the vastus medialis oblique and vastus lateralis had increasingly significant differences in the Q-setting sensorimotor training group (P<.05), and there were no significant differences between the groups (P>.05). Conclusion: Q-setting exercise with sensorimotor training was a useful method that improved the balance of vastus medialis oblique (VMO) and vastus lateralis (VL) activity after meniscectomy.

In this study, we investigated the effects of neuromuscular electrical stimulation (NMES) on the treatment of 20 acute stroke patients with dysphagia. For both the treated and control groups, the basic facial stimulation training was conducted for 30 minutes, five times a week, for four weeks. NMES was performed on the treated group only, for 30 minutes each time. Both groups were evaluated according to the functional dysphagia scale (FDS) using a videofluoroscopic swallowing study (VFSS). After the treatment was performed for four weeks, the FDS results of the treated group showed a significance difference in oral transit time in the oral phase and in the triggering of pharyngeal swallow fluid, laryngeal elevation and epiglottic closure, nasal penetration, residue in valleculae, coating of pharyngeal wall after swallow fluid, and pharyngeal transit time in the pharyngeal phase. In addition, the treated group showed a significant difference in laryngeal elevation and epiglottic closure, nasal penetration, and pharyngeal transit time in the pharyngeal phase after the treatment compared to the control group. The results of this study showed that neuromuscular electrical stimulation may be an effective method of treating dysphagia in acute phase stroke patients.

Delayed onset muscle soreness is a sensation of discomfort that occurs 24 h after exercise, and it is associated with the performance of unfamiliar and high force muscle work, such as eccentric contractions . The injury to the muscle has been well described but the mechanism underlying the injury is not fully understood. Although the pathophysiological processes underlying delayed onset muscle soreness are not completely understood, many researchers have investigated various treatments in a attempt to reduce the soreness. These treatments have focused on reducing the inflammation, or edema; consequent to tissue damage, and breaking up the cycle which is thought provoke tonic muscle spasm or pain. Physical therapy is the most importance thechniques to reduce delayed onset muscle soreness. Physical therapy on delayed onset muscle soreness includes massage, exercise, therapeutic ultrasound, TENS, stretching and cryotherapy. this investigation should encourage physical therapists to experiment further with various techniques to reduce delayed onset muscle soreness.

Active movement is able to actively contract his muscles and move a segment either with or without assistance. This movement maintain physiologic elasticity and contractility of the participating muscles, provide sensory feedback from the contracting muscles and stimulus for bone integrity as well as increase circulation and prevent thrombus formation, in addition to develop coordination and motor skills for functional activities. Passive movement is the motion to the external force; gravity, machine, another individuals. Active movement is more activated rather than passived on the central nervous system. Therefore, we think that active movement is more effected facilitating through specific inhibitory mobilization of muscle.
