Static surface electromyography can provide an objective test of the cervical, thoracic, and lumbar posterior areas that needs to be performed within a clear clinical or ergonomic context. It is of great help in postural assessment in the standing position in people with healthy backs or postural dysfunctions. The author has devised a protocol that allows statistically based treatment and more ...

Physiologic assessment of diseases of the motor unit from the anterior horn cells to the muscles relies on a combination of needle electromyography (EMG) and nerve conduction studies (NCS). Both require a unique combination of knowledge of peripheral nervous system anatomy, physiology, pathophysiology, diseases, techniques, and electricity is necessary. Successful, high-quality, reproducible EM...

Foot drop is a disease caused mainly by muscle paralysis, which incapacitates the nerves generating the impulses that control feet in a heel strike. The incapacity may stem from lesions that affect the brain, the spinal cord, or peripheral nerves. The foot becomes dorsiflexed, affecting normal walking. A design and analysis of a controller for such legs is the subject of this article. Surface e...

BACKGROUND Botulinum chemodenervation has been increasingly used for treating conditions characterized by muscular pain and dystonia. Complication rates commonly exceed 10 percent in published accounts due to an inadvertent spread of toxin. Various techniques of precision targeting have been described to minimize undesirable toxin effects. The present study reports on a clinical experience comb...

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...
