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.

Purpose: This study investigates the effects of task-oriented training for a left trunk flexion pattern using real-time ultrasound imaging in a stroke patient with unilateral neglect symptoms. Methods: This study used the ABA experimental design, which is a single-subject research method among individual case research methods. For the ABA experimental design, changes in the degree of unilateral neglect, balance ability, and the thickness of the lateral abdominal muscle were visually analyzed during the baseline process, in the intervention period, and after the intervention. The experiments were performed 24 times in total for 8 times in each of the 3 periods. The unilateral neglect was measured using the Albert test, balance ability was measured using the Berg balance test, and the thickness of the lateral abdominal muscle was measured using ultrasound imaging. The subject was a 50-year-old male patient with unilateral neglect caused by right cerebral hemorrhage. He performed task-oriented training for a voluntary left trunk flexion pattern using real-time ultrasound imaging during the intervention period. Results: The result of comparing the data collected during the intervention period with the data point average of the baseline process showed that balance ability improved and the tendency line was above the baseline. The tendency line of unilateral neglect was below the baseline and showed a decreasing tendency. The thickness of the lateral abdominal muscle showed an increasing trend and the tendency line was above the baseline. Conclusion: The results of this study suggest that the task-oriented training for left trunk flexion pattern using real-time ultrasound imaging has a beneficial effect on balance ability, the degree of unilateral neglect, and the strength of the lateral abdominal muscle in unilateral neglect patients.

Purpose: The aim of this study was to examine the activation of the contralateral upper and lower extremities and trunk muscle during ipsilateral upper extremity diagonal isokinetic exercise. Methods: Twenty-one healthy male subjects with no history of shoulder injury undertook ipsilateral diagonal isokinetic exercise at 60, 120, and $180^{\circ}/sec$, utilizing a standard Biodex protocol. Muscle activation amplitudes were measured in the upper trapezius, pectoralis major, biceps brachii, rectus abdominis, external oblique, rectus femoris, adductor longus, and biceps femoris muscles using electromyography. A one-way analysis of variance and paired t-tests were conducted, and the data were analyzed using SPSS, version 21.0. Results: The results revealed no statistically significant interaction between motion and angular velocity and no statistically significant contralateral muscle activation according to angular velocity (p>0.05). However, they revealed statistically significant contralateral muscle activation according to motion (p<0.05). Conclusion: These results suggest that the movements involved in contralateral upper extremity diagonal isokinetic exercise can enhance muscle strength in patients affected by stroke, fracture, burns, or arthritis.
