The effects of the neck stabilization exercise on the muscle activity of trunk respiratory muscles and maximum voluntary ventilation of chronic stroke patients.

Background: Unstable neck posture, muscle imbalance, and segmental instability can cause neck pain and decrease the respiratory function.

Objective: To examine effects of a neck stabilization exercise on respiratory muscle activity and maximal voluntary ventilation (MVV) in patients with a chronic stroke.

Methods: A total of 40 patients with a chronic stroke participated in this study.

A comparison of the shoulder and trunk muscle activity according to the various resistance condition during push up plus in four point kneeling.

[Purpose] This study was to compare the shoulder and trunk muscle activity according to the various resistance condition during knee push-up-plus. [Subjects and Methods] Twenty healthy adults participated in this study (9 males and 11 females). The subjects performed dominant-leg-extended knee push-up-plus apply to resistance in the direction of abduction, adduction, extension and the flexion.

The influence of an ankle foot orthosis on the percentage of weight loading during standing tasks in stroke patients.

[Purpose] The aim of this study was to investigate the effects of an ankle foot orthosis on weight-bearing abilities of stroke patients by comparing weight loading during performance of tasks in various standing positions on the affected side. [Subjects and Methods] This study was performed with 16 stroke patients. To measure the weight loading value and percentage of weight loading in affected lower extremities, 5 standing tasks were performed with and without an ankle foot orthosis in random order.

Effect of ankle-foot orthosis on weight bearing of chronic stroke patients performing various functional standing tasks.

[Purpose] This study examined how an ankle-foot orthosis (AFO) influences the weight-bearing of chronic stroke patients during the performance of five functional standing tasks. [Subjects and Methods] Sixteen patients with stroke participated in this experiment. The subjects performed functional standing tasks with or without the AFO and weight bearing was measured during the tasks.

Effects of neck exercises on swallowing function of patients with stroke.

[Purpose] This study examined the effects of neck exercises using PNF on the swallowing function of stroke patients with dysphasia. [Subjects and Methods] A total of 26 study subjects were selected and randomly divided into an experimental group of 13 subjects, who received the PNF-based short neck flexion exercises, and a control group of 13 subjects, who received the Shaker exercise. [Results] The experimental group showed statistically significant improvements in premature bolus loss, residue in the valleculae, laryngeal elevation, epiglottic closure, residue in the pyriform sinuses, and coating of the pharyngeal wall after swallowing, and improvements in pharyngeal transit time, and aspiration on both the new VFSS scale and the ASHA NOMS scale.

Effects of neck exercise on high-school students' neck-shoulder posture.

[Purpose] This study examined the effects of deep flexor muscle-strengthening exercise on the neck-shoulder posture, and the strength and endurance of the deep flexor muscles of high-school students. [Subjects] The subjects were 30 seventeen-year-old female high-school students who complained about bad posture and chronic neck-shoulder pain. They were randomly divided into an experimental group of 15 subjects, who performed a deep flexor muscle-strengthening exercise and a control group of 15 subjects, who performed a basic stretching exercise.

Comparison of expression of inflammatory cytokines in the spinal cord between young adult and aged beagle dogs.

Aging is an inevitable process that occurs in the whole body system accompanying with many functional and morphological changes. Inflammation is known as one of age-related factors, and inflammatory changes could enhance mortality risk. In this study, we compared immunoreactivities of inflammatory cytokines, such as interleukin (IL)-2 (a pro-inflammatory cytokine), its receptor (IL-2R), IL-4 (an anti-inflammatory cytokine), and its receptor (IL-4R) in the cervical and lumbar spinal cord of young adult (2-3 years old) and aged (10-12 years old) beagle dogs using immunohistochemistry and western blotting.
