Optimization and Effect of Water Hardness for the Production of Slightly Acidic Electrolyzed Water on Sanitization Efficacy.

Slightly acidic electrolyzed water (SAEW) has been recently proposed as a novel promising sanitizer and cleaner in the agricultural and food industries. However, several factors, including water hardness, were considered to strongly affect the physical properties and sanitization efficacy of SAEW. To study the effect of water hardness on the SAEW production, we evaluated the production properties and sanitization effect of SAEW, which was generated from water sources in 16 representatively geographical locations of South Korea.

Changes in rounded shoulder posture and forward head posture according to exercise methods.

[Purpose] This study aimed to determine the effect of forward head posture-improving exercises on rounded shoulder posture when employing the self-stretch exercise, the McKenzie exercise, and the Kendall exercise as intervention methods based on previous studies that reported negative effects of unbalanced posture and musculoskeletal problems on forward head posture and rounded shoulder posture.

The selected subjects had sufficient muscle strength for the experiment and normal joint range of motion.

The effects of self-mobilization techniques for the sciatic nerves on physical functions and health of low back pain patients with lower limb radiating pain.

[Purpose] This study aimed to examine the effects of self-mobilization techniques for the sciatic nerves on the quality of life in patients with chronic low back pain in the lower limbs accompanied by radiating pain. [Subjects and Methods] The subjects were divided into two groups: a group receiving of lumbar segmental stabilization exercise training including sciatic nerve mobilization techniques, which included 8 males and 7 females, and a group receiving lumbar segmental stabilization exercise training, which included 8 males and 7 females. [Results] There were statistically significant differences in comparison of measurement results between the groups before and after the intervention.

The effect of lumbar stabilization exercises and thoracic mobilization and exercises on chronic low back pain patients.

[Purpose] To investigate whether pain, balance, and stabilization of the lumbar region can be improved through thoracic mobilization in addition to lumbar stabilizaing exercises. [Subjects and Methods] This study recruited 36 subjects with chronic low back pain lasting more than 12 weeks. The subjects recruited for this study participated voluntarily, and provided their signed consent to participation.

The effects of gluteus muscle strengthening exercise and lumbar stabilization exercise on lumbar muscle strength and balance in chronic low back pain patients.

[Purpose] The aim of this study was to examine the effects of exercise to strengthen the muscles of the hip together with lumbar segmental stabilization exercise on the lumbar disability index, lumbar muscle strength, and balance. [Subjects and Methods] This study randomly and equally assigned 40 participants who provided written consent to participate in this study to a lumbar segmental stabilization exercise plus exercise to strengthen the muscles of the gluteus group (SMG + LES group) and a lumbar segmental stabilization exercise group. [Results] Each evaluation item showed a statistically significant effect.

Comparison of physical function according to the lumbar movement method of stabilizing a patient with chronic low back pain.

[Purpose] The purpose of this study was to examine the changes caused by lumbar stabilization exercises in chronic low back pain patients. [Subjects and Methods] Swiss ball exercise regimen group and sling exercise regimen group exercised for 30 minutes a day, 5 days a week, for 12 weeks. The control group was to continue performing their usual daily living activities.

Influence of the application of inelastic taping on shoulder subluxation and pain changes in acute stroke patients.

[Purpose] The purpose of this study was to investigate the impact on the shoulder joints of performing inelastic taping and bed physical therapy for acute stroke. [Subjects and Methods] The intervention was conducted for eight weeks with an experimental group of 18 stroke patients who received bed physical therapy and inelastic taping and a control group of 18 stroke patients who received only bed physical therapy. [Results] After the intervention, the subluxation degree of the experimental group, which received bed physical therapy and inelastic taping, was found to be significantly different from that of the control group, which received only bed physical therapy.

The effect of non-elastic taping on balance and gait function in patients with stroke.

[Purpose] This study investigated the influence of exercise on balance ability and gait function in stroke patients after applying non-elastic tape, which can stabilize muscles and joints, to the lower extremities of the affected side.
