Article history: Received: .................. Accepted: ................... Available online: ........ ZJRMS 2015.....; X(X): XX-XX Background: Stabilization exercises lead to improve muscle performance and can be used to prevent and treat of low back pain. Aim of this study is to evaluate and compare the level of abdominal and lumbar muscles activity during two types of stabilization exercises...

STUDY DESIGN Controlled laboratory study using a repeated-measures, counterbalanced design. OBJECTIVES To test the ability of 8 Swiss ball exercises (roll-out, pike, knee-up, skier, hip extension right, hip extension left, decline push-up, and sitting march right) and 2 traditional abdominal exercises (crunch and bent-knee sit-up) on activating core (lumbopelvic hip complex) musculature. BA...

[Purpose] The purpose of this study was to identify changes in the thickness of the deep cervical flexors (DCFs) according to the degree of mouth opening (MO) in normal adults. [Subjects] The study's subjects were 50 normal adults (30 men, 20 women). [Methods] Ultrasound was used to obtain images of muscles, and the NIH ImageJ software was used to measure the thickness of each muscle. [Results]...

PURPOSE This is a pilot study to determine if endurance exercises for dorsiflexors will improve walking for people with foot drop secondary to MS, and if improvement in muscle endurance for persons with MS can be predicted based on the amount of central fatigue (CF) in the muscle. SUBJECTS Five individuals with foot drop secondary to MS and five age-matched controls. METHODS The interventio...

Purpose: The present study aimed to investigate the effect of voluntary and electrically stimulated quadriceps muscle fatigue on postural control. Methods: Sixteen healthy young males participated in this quasi-experimental study. All subjects performed two fatiguing exercises with equal intensity of isometric maximal voluntary contraction: Voluntary (VOL) and Electrical Stimulation (ES). The ...

[Purpose] It is well-known that the muscles of spinal stability also play roles in respiration. The spinal stability muscles are divided into two subgroups, the local muscle group and the global muscle group. Appropriately coordinated activation of muscle groups are recommended for more efficient spinal stability. The indirect method of measuring coordination of muscle groups is the synergist r...

Sample size calculation: Can the authors provide means and SDs on which the effect size (of 0.66) is estimated (for the main trial), rather than stating an effect size without any justification? It may be that this effect size is unrealisic, in which case the main trial would be underpowered at 30 per group. A sample size of 12 per group for the pilot study is very small and I am concerned that...

BACKGROUND Metastatic bone disease is a common and severe complication in patients with advanced cancer. Radiotherapy (RT) has long been established as an effective local treatment for metastatic bone disorder. This study assesses the effects of RT combined with muscle-training exercises in patients with unstable bone metastases of the spinal column from solid tumors. The primary goal of this s...
