Purpose: The purpose of this study was to compare the strength and walking ability of chronic stroke patients following either proprioceptive neuromuscular facilitation (PNF) pattern training with pressure biofeedback units (feedback group) or PNF pattern training without pressure biofeedback units (control group). Methods: Eighteen participants with chronic stroke were recruited from a rehabilitation hospital. They were divided into two groups: a feedback group (n = 8) and a control group (n = 10). They all received 30 minutes of neurodevelopmental therapy and PNF training for 15 minutes five times a week for three weeks. Muscle strength and spatiotemporal gait parameters were measured. Muscle strength was measured by hand-held dynamometer; gait parameters were measured by the Biodex Gait trainer treadmill system. Results: After the training periods, the feedback group showed a significant improvement in hip abductor muscle strength, hip extensor muscle strength, step length of the unaffected limb, and step time of the affected limb (p<0.05). Conclusion: The results of this study showed that proprioceptive neuromuscular facilitation pattern training with pressure biofeedback units was more effective in improving hip muscle strength and walking ability than the proprioceptive neuromuscular facilitation pattern training without pressure biofeedback units. Therefore, to strengthen hip muscles and improve the walking ability of stroke patients, using pressure biofeedback units to improve trunk stability should be considered.

Nerve conduction study (NCS) is an electrophysiological tool to assess the overall function of cranial and peripheral nervous system, therefore NCS has been diagnostically helpful in the identification and characterization of disorders involving nerve roots, peripheral nerves, muscle and neuromuscular junction, and are frequently accompanied by a needle Electromyography. Furthermore, NCS could provide valuable quantitative and qualitative results into neuromuscular function. Usually, motor, sensory, or mixed nerve studies can be performed with using NCS, stimulating the nerves with the recording electrodes placed over a distal muscle, a cutaneous sensory nerve, or the entire mixed nerve, respectively. And these findings of motor, sensory, and mixed nerve studies often show different and distinct patterns of specific abnormalities indicating the neuromuscular disorders. The purpose of this special article is to review the neurophysiologic usefulness of NCS, to outline the technical factors associated with the performance of NCS, and to demonstrate characteristic NCS changes in the setting of various neuromuscular conditions.

This study evaluated and compared the effectiveness on upper motor extremity function between proprioceptive neuromuscular facilitation which has been frequently used in clinical practice, and action observation training in terms of improving upper motor extremity function. A study with a single-subject design (A-B-C-A') was conducted with a patient who was diagnosed with left hemiplegia. A repeated-measure analysis was conducted to assess results of the Wolf Motor Function Test (WMFT), Box and Block Test (BBT), and grip and pinch strength test performed daily in the study for 4 weeks. The results of the analysis indicated that the WMFT score, BBT score, grip strength, and pinch strength were improved from 29.60 to 39 (24.10%), from 1.67 to 4.93 each (EA) (66.22%), from 2.06 to 2.66 libras (lbs) (22.61%), and from 1.57 to 1.93 lbs (18.94%), respectively, from the baseline period to treatment period B. The values were improved from 29.60 to 42.20 (29.86%), from 1.67 to 7 EA (76.21%), from 2.06 to 3.47 lbs (40.57%), and from 1.57 to 1.67 lbs (6.12%), respectively, from the baseline period to treatment period C. From treatment period B to treatment period C, the WMFT score, BBT score, and grip strength were improved from 39 to 42.20 (7.58%), from 4.93 to 7 EA (29.56%), and from 2.66 to 3.47 lbs (23.20%), respectively, but pinch strength was decreased from 1.93 to 1.67 lbs (15.83%). In conclusion, proprioceptive neuromuscular facilitation and action observation training both have positive effects on upper extremity motor function. However, we suggest that the posttreatment effect of action observation training was better than that of proprioceptive neuromuscular facilitation.
