Retrograde neuronal tracing with horseradish peroxidase (HRP) was used to determine the position in the spinal cord of motor neurone pools innervating muscles in the regenerated axolotl hindlimb. This method allows a detailed analysis of the accuracy of reformation of neuromuscular connections. The results show that regenerated distal limb muscles are reinnervated by motor neurones in the same ...

We report the case of a 75-year-old woman who developed involuntary jerks of the abdominal musculature. They occurred spontaneously or triggered by a forced inspiration or attempts to rise from the supine position. Electromyography (EMG) recorded abnormal bursts of muscle activity in the abdominal, thoracic paraspinal, and intercostal muscles up to the 3rd intercostal space. The bursts were bil...

shoulder movements are a complex motor act, controlled by many muscles attached to thescapula and the vertebral column. these muscles are innervating by motoneurons (mns) located in theventral horn of the spinal cord. motoneurons of the ventral horn are arranged such that several groups ofmns can be distinguished in a transverse section through the spinal cord. the anatomical or functionalimpli...

We investigated autonomic control of cardiovascular function in able-bodied (AB), paraplegic (PARA), and tetraplegic (TETRA) subjects in response to head-up tilt following spinal cord injury. We evaluated spectral power of blood pressure (BP), baroreflex sensitivity (BRS), baroreflex effectiveness index (BEI), occurrence of systolic blood pressure (SBP) ramps, baroreflex sequences, and cross-co...

BACKGROUND Previous studies have demonstrated the existence era reflex response, measurable by surface electromyography (sEMG), after manually delivered spinal manipulative therapy (SMT). This reflex response has been characterized as consistent, reproducible within individual subjects, and nonlocal because it extends beyond the site of manipulation. However, the nature and magnitude of possibl...

This work proposes an identification methodology to estimate the residual tension values (tones) for human trunk muscles, including deep ones, using multidirectional stiffness data in association with numerical modeling. The role of this muscle or contraction is maintain posture and balance. Knowledge tone useful diagnosis treatment several spinal diseases important realistic modeling simulatio...

Limited back motion and damage of paraspinal muscles after spinal fusion surgery may lead to abnormal compensatory movements of the body. Whether neuromuscular control changes after surgery remains unclear. The purpose of the study was to identify the muscle activation patterns employed before and after lumbar spinal fusion. Nineteen patients having low back pain and undergoing minimally invasi...

the purpose of this study was to determine the effect of combination specific resistance and ordinary swimming  training on breaststroke swimming  performance in young boys. twenty boys of alborz  province  swimming team age of 13±1 years ,weight 50/ 65±1/02kg and height 159/8 ±4/91cm, participated in this study. after the initial testing of the performance variable (fifty-meter record of breas...

Lower thoracic spinal cord stimulation (SCS) results in the generation of large positive airway pressures (Paw) and may be a useful method of restoring cough in patients with spinal cord injury. The purpose of the present study was to assess the mechanical contribution of individual respiratory muscles to pressure generation during SCS. In anesthetized dogs, SCS was applied at different spinal ...
