Background: Aging often results in thoracic kyphosis and adverse postural changes. This may interfere with physiologic activity of paraspinal muscles. Few styles of spinal orthosis have been already used to reduce thoracic kyphosis. This paper describes the development of a novel orthosis, which is designed based on the anatomy of the back muscles. This novel orthosis may potentiate muscle acti...
BACKGROUND Prolonged sitting leads to low back discomfort and lumbopelvic muscle fatigue. This study examined the characteristics of body perceived discomfort and trunk muscle fatigue during 1 hour of sitting in three postures in office workers. METHODS Thirty workers sat for 1 hour in one of three sitting postures (i.e., upright, slumped, and forward leaning postures). Body discomfort was as...
Objective: Neck pain is one of the most common musculoskeletal disorders. Structural and functional alteration of cervical muscles is a commonly-reported complication of chronic neck pain (CNP). Measurement of muscle thickness is an acceptable way to evaluate muscle morphological structure. Therefore, this study aimed to measure cervical extensor muscles thickness in individuals with chronic no...
Whether interlimb reflexes emerge only after a severe insult to the human spinal cord is controversial. Here the aim was to examine interlimb reflexes at rest in participants with chronic (>1 year) spinal cord injury (SCI, n = 17) and able-bodied control participants (n = 5). Cutaneous reflexes were evoked by delivering up to 30 trains of stimuli to either the superficial peroneal nerve on the ...
Introduction and aim: In the past few decades, exercise has been promoted with increasing interest for the treatment of back pain. Therefore, the present study aimed to investigate the effect of rehabilitation exercises with medicine beta balls on the directional and general contraction of ankle joint muscles in patients with low back pain during walking. Methods: The present study was a clini...
This study aimed to examine the effects of kinesiology taping (KT) and different TRX suspension workouts on the amplitude of electromyographic (EMG) activity in the core muscles among people with chronic low back pain (LBP). Each participant (total n = 21) was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1) hamstring curl, (2) hip abductio...
Introduction: Low back pain is one of the most common musculoskeletal disorders leading to disability around the world. Several studies have suggested that prolonged computer/ laptop work contributes to the development of low back pain and discomfort. The results of the studies conducted on the association of back discomfort and muscle activity are contradictory. Thus, the present study aims to...
Background and purpose: Changes in neuromuscular control of the neck muscles, is one of the problems associated with neck pain. The purpose of the present study was to review the previously published studies concerning the effect of chronic neck pain on neuromuscular control of cervical region. Materials and methods: A literature search was performed for the studies published in 1990-2014 in...
STUDY DESIGN A normative, single-group study was conducted. OBJECTIVE To investigate the flexion relaxation phenomenon in the thoraco-lumbopelvic muscles among a pain-free population when moving from an upright to a slump sitting posture. SUMMARY OF BACKGROUND DATA The presence of the flexion relaxation phenomenon (FRP) of the back muscles is well documented at end-range spinal flexion when...
background: the comparison between voluntary and automatic contraction of deep abdominal muscles in patients with nonspecific low back pain (nlbp) may justify being the best treat for them. the aim of this case-controlled study was to compare changes in the thickness of the transverses abdomin is (tra) and internal oblique (io) muscles during the abdominal drawing-in maneuver (adim) and the act...
