Background and aims Recordings of electrical activity in the muscle and surface electromyography (EMG) have been widely used in the field of applied physiology. In parallel to recording of the EMG, the detectable low-frequency vibration signal generated by the skeletal muscle has been known and well documented. As the nature of the signal has been progressively revealed, the term of mec...
Objective: Low back pain (LBP) is one of the most common and costly health problems. Changes in muscle activity and recruitment of lumbar deep muscles which are responsible for lumbar spine stability have been reported in patients with LBP. Different exercise programs are used in the treatment of such patients to improve spinal stability. The purpose of this study was to systematically review t...
characterized by muscle stiffness and an inability of the muscle to quickly relax after voluntary contraction. although myotonia can affect any skeletal muscles, including muscles of the face and tongue, it occurs most often in the legs. myotonia causes muscle stiffness (a myotonic disorder should be considered in the differential diagnosis of a patient complaining of muscle stiffness) that can...
Introduction: Repetitive strain injuries are one of the most prevalent problems in occupational diseases. Repetition, vibration and bad postures of the extremities are physical risk factors related to work that can cause chronic musculoskeletal disorders. Repetitive work on a computer with low level contraction requires the posture to be maintained for a long time, which can cause muscle fatigu...
Pyomyositis is a pyogenic infection of the skeletal muscle characterized by muscle pain and swelling. The illness is more commonly seen in the tropics. The diagnosis of pyomyositis is difficult due to its vague clinical presentation and poor localizing signs. The differential diagnosis includes osteomyelitis, septic arthritis, muscle hematoma, muscle rupture and deep vein thrombosis. A delay in...
Background and Objective: Although there is evidence for an association between forward head posture and scapular muscles role, few studies consider the issue how this relationship might be. Therefore, the purpose of this study was to compare contribution ratio of scapular muscle during arm abduction in subjects with and without forward head posture. Methods: 18 female (mean age 22.6 years) wi...
Objectives: Different theories have been suggested to define factors involved in skeletal and craniofacial morphology. Many of these theories explain that the bone morphology is the result of the bone tissue capability to adapt in response to biomechanical forces exerted during growth. Also, it seems logical to hypothesize that there is a relationship between biomechanical connections of muscle...
background: alterations in the neuromuscular control of the spine were found in patients with chronic low back pain (clbp). sudden loading of the spine is assumed to be the cause of approximately 12% of lower back injuries. however, some aspects of this problem, such as alterations in the sensory–motor control of the spine, remain questionable. this study investigated postural and neuro–motor c...
background delayed onset muscle soreness (doms) is the sensation of stiffness and pain in the muscles that occurs 24-48 hours after unaccustomed or strenuous exercise. objectives the aim of this study was to examine and compare the effect of vibration training (vt) on delayed onset muscle soreness. materials and methods twenty healthy non-athletic volunteers (female, age 20-30 years, body mass ...
Background: The aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage. Methods : A total of 14 healthy females participated in this pre-experimental study. The subjects performed maximal eccentric quadriceps contractions at ...
