Abstract ▼ AI-Helper

This study investigated the effects of indirectly applying proprioceptive neuromuscular facilitation (PNF) to the scapular adductor muscles of stroke patients on their scapular movements and walking ability. Five patients who were diagnosed with stroke participated in this study as a single group. PNF patterns were applied to the scapulae anterior elevation and posterior depression patterns and upper limbs patterns of the patients in side lying and sitting positions together. The data were analyzed with a paired t-test in order to identify within-group differences in the measurements before and after the intervention. The scapular movements of the upper and lower parts, weight bearing and walking speed were significantly improved in the stroke patients after the application of PNF (p<0.05). These results suggest that PNF training effective in improving the scapular movements and walking ability in patients with stroke.

문제 정의

05). As clinical research on the effects of PNF on changes in the scapular movements, weight loading, and walking of stroke patients, this study provides important data for treating such patients. Further studies on more patients may be needed to generalize the results of this study.
Although there have been many studies using proprioceptive neuromuscular facilitation (PNF) for stroke, sports injuries, and musculoskeletal disorders, little research has been done on the effects of the intervention on the scapular movements and walking of stroke patients when it is applied to their scapular adductors. In this context, this study attempted to identify the effects of training using PNF on the scapular adductors of stroke patients.

제안 방법

A portable compact control unit attached to the ankle temporarily saved the patient's walking data, which was wirelessly sent to a computer on which Smart Step was installed and evaluated the walking ability.
In this study, although the patients did not undergo exercise applied directly to the affected lower limbs, the PNF applied to their scapular adductors, muscles that are closely related to the limbs, led to improvements in weight loading and walking speed. These results are consistent with those of Pontzer et al¹⁸⁾ and Choi JH et al¹⁹⁾, demonstrating that scapular movements and upper limb functions are intimately associated with walking.
In this study, we applied PNF to the scapular adductors in order to identify its effects on the scapular movements of the affected side and walking of stroke patients. Statistically significant changes were observed in the scapular movements (p < .
And exclusion criteria for the study were¹⁾ had cardiovascular patients²⁾, medical, or orthopedic disorders that could affect treatment. They performed a treatment program consisting of 30- minute sessions five times per week for six weeks.
We measured the distance from the spinous process of the second vertebra to the superior angle of the scapula and the distance from the spinous process of the seventh vertebra to the inferior angle of the scapula when the subject was in a comfortable sitting position, in order to identify differences. To investigate walking ability, we measured the pressure on the fore and heel of the foot by using a sensor attached to the insole. A portable compact control unit attached to the ankle temporarily saved the patient's walking data, which was wirelessly sent to a computer on which Smart Step was installed and evaluated the walking ability.

대상 데이터

The subjects were five patients who were admitted to a hospital in Seoul from 2 .Jan, 2017 to 10 Feb, 2017; Subjects were screened according to the following inclusion and exclusion criteria.
There were four men and one woman in the study group. The participants’mean age was 49.

성능/효과

The results of this study show that PNF may improve the movement of the scapulae and walking when it is applied to the scapular adductors of stroke patients. Further studies may be needed to identify the effects of more diversified patterns and techniques.
Weight bearing and speed while walking, which were measured to identify changes in walking ability between pre- and post-intervention, showed statistically significant changes (p < 0.05).
