Motor, Sensory, and Autonomic Function in Traumatic Spinal Cord Injury After the LION Procedure.

2018-02-26 20:24:12 | BioPortfolio

Summary

Possover pioneered a minimally invasive and fully reversible laparoscopic technique, laparoscopic implantation of neuroprosthesis (LION), for precise placement of an implantable pulse generator and one to four leads for stimulating nerves of the lumbosacral plexus.

Unexpectedly, Possover in 2014 made the clinical observation that four patients with complete and incomplete chronic traumatic spinal cord injury regained significant motor and sensory function following the LION procedure for bladder and bowel dysfunction.

The primary objective of this randomized clinical trial is to investigate whether the LION procedure and the subsequent neurostimulation in individuals with chronic traumatic thoracolumbar spinal cord injury with spastic paraplegia is associated with increased walking capacity.

Description

Sustaining a spinal cord injury impacts the mental and physical wellbeing of the injured individuals profoundly; quality of life suffers and subsequently the risk of suicide is greatly increased as compared to the general population. While spinal cord injury compromises an individual's mobility, dependency does not necessarily ensue; most individuals will require a wheelchair, braces or other assistive devices for maintaining activities of daily living and participating in society i.e. work, sport etc.

Furthermore, individuals with spinal cord injury face numerous medical complications and reduced life expectancy as a direct result of their disability.Detrusor over-activity and sphincter dyssynergia are seen in up to 85% of cases and improved control of micturition and defaecation closely follows restoration of ambulation as primary rehabilitation goals of patients with spinal cord injury.

Recovery after initial inpatient rehabilitation is at best modest and conversion rate of the American Spinal Injury Association Impairment Scale grade remain poor for grades A and B. Likewise, the rate of motor improvement stagnates over time leaving many patients with permanent motor, sensory and autonomic deficits. 9-12 months after their initial injury, most patients have essentially exhausted their possibility of further restorative treatments.

Possover pioneered a minimally invasive and fully reversible laparoscopic technique, laparoscopic implantation of neuroprosthesis (LION), for precise placement of an implantable pulse generator and one to four leads for stimulating nerves of the lumbosacral plexus; a significant number cases suggest this technique is safe and efficacious in treating overactive and atonic bladder disturbances, neurogenic bowel dysfunction, and abdominopelvic neuropathic pain.

Unexpectedly, Possover in 2014 made the clinical observation that four patients with complete and incomplete chronic traumatic spinal cord injury regained significant motor and sensory function following the LION procedure for bladder and bowel dysfunction. Expanding further on the topic, Possover have recently published an updated case series of 18 patients om whom 16 are now capable of weight bearing standing and 12 are furthermore capable of voluntary stepping.

The primary objective of this randomized clinical trial is therefore to investigate whether the LION procedure and the subsequent neurostimulation in individuals with chronic traumatic thoracolumbar spinal cord injury with spastic paraplegia is associated with increased walking capacity.

Medical and Biotech [MESH] Definitions

Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.

Penetrating and non-penetrating injuries to the spinal cord resulting from traumatic external forces (e.g., WOUNDS, GUNSHOT; WHIPLASH INJURIES; etc.).

A syndrome associated with damage to the spinal cord above the mid thoracic level (see SPINAL CORD INJURIES) characterized by a marked increase in the sympathetic response to minor stimuli such as bladder or rectal distention. Manifestations include HYPERTENSION; TACHYCARDIA (or reflex bradycardia); FEVER; FLUSHING; and HYPERHIDROSIS. Extreme hypertension may be associated with a STROKE. (From Adams et al., Principles of Neurology, 6th ed, pp538 and 1232; J Spinal Cord Med 1997;20(3):355-60)

Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop. (From Adams et al., Principles of Neurology, 6th ed, p1269)

Reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries. This condition may be associated with ARTERIOSCLEROSIS, trauma, emboli, diseases of the aorta, and other disorders. Prolonged ischemia may lead to INFARCTION of spinal cord tissue.
