ElectroanalgesiaElectroanalgesia is a form of analgesia, or pain relief, that uses electricity to ease pain. Electrical devices can be internal or external, at the site of pain (local) or delocalized throughout the whole body. It works by interfering with the electric currents of pain signals, inhibiting them from reaching the brain and inducing a response; different from traditional analgesics, such as opiates which mimic natural endorphins and NSAIDs (non-steroidal anti-inflammatory drugs) that help relieve inflammation and stop pain at the source.
SpondylolisthésisLe spondylolisthésis (du grec ancien , vertèbre, et , action de glisser) désigne une affection du squelette humain, caractérisée par le glissement d'une vertèbre en avant de la vertèbre située en dessous d'elle (antéspondylolisthésis) ou en arrière (rétrolisthésis). Les vertèbres les plus souvent concernées sont la quatrième et la cinquième vertèbre lombaire. La spondylolyse est une perte de continuité de l'isthme articulaire (pars interarticularis), situé entre les deux apophyses articulaires supérieure et inférieure de l'arc vertébral postérieur.
Pelvic painPelvic pain is pain in the area of the pelvis. Acute pain is more common than chronic pain. If the pain lasts for more than six months, it is deemed to be chronic pelvic pain. It can affect both the male and female pelvis. Common causes in include: endometriosis in women, bowel adhesions, irritable bowel syndrome, and interstitial cystitis. The cause may also be a number of poorly understood conditions that may represent abnormal psychoneuromuscular function. The role of the nervous system in the genesis and moderation of pain is explored.
Piriformis syndromePiriformis syndrome is a condition which is believed to result from compression of the sciatic nerve by the piriformis muscle. The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick. The sciatic nerve forms the roots of L4-S3 segments of the lumbosacral plexus. The nerve will pass inferiorly to the piriformis muscle, in the direction of the lower limb where it divides into common tibial and fibular nerves.
Mal de PottLe mal de Pott est une spondylodiscite, c'est-à-dire une infection d'un disque intervertébral ou des corps vertébraux adjacents, due au bacille de la tuberculose. Il s'agit d'une urgence médicale qui nécessite une prise en charge rapide, une antibiothérapie lourde et longue ( de traitement) et parfois un traitement chirurgical orthopédique. Sa dénomination provient du chirurgien britannique Percivall Pott, connu pour ses travaux sur cette maladie. Il représente 50 % des manifestations de la tuberculose ostéoarticulaire.
Area postremaThe area postrema, a paired structure in the medulla oblongata of the brainstem, is a circumventricular organ having permeable capillaries and sensory neurons that enable its dual role to detect circulating chemical messengers in the blood and transduce them into neural signals and networks. Its position adjacent to the bilateral nuclei of the solitary tract and role as a sensory transducer allow it to integrate blood-to-brain autonomic functions.
