NEUROwave - Extracorporeal Shock Wave Therapy (ESWT) in Acute Traumatic Complete (AIS A) and Incomplete (AIS B-D) Cross-sectional Lesions on Motor and Sensory Function Within Six Months After Injury
The Effect of Extracorporeal Shock Wave Therapy (ESWT) in Acute Traumatic Complete (AIS A) and Incomplete (AIS B-D) Cross-sectional Lesions on Motor and Sensory Function Within Six Months After Injury: A Two-arm Three-stage Adaptive, Prospective, Multi-center, Randomized, Double-blind, Placebo-controlled Clinical Trial
It has been hypothesized that there are two mechanisms of acute traumatic spinal cord injury (SCI): the primary mechanical damage and the secondary injury due to additional pathological processes initiated by the primary injury. Neurological damage due to laceration, contusion, distraction or compression of the spinal cord is called ''primary injury''. This mechanical injury leads to a cascade of biochemical and pathological changes, described as ''secondary injury'', which occurs minutes to weeks after the initial trauma and causes further neurological deterioration. This secondary cascade involves vascular changes, an inflammatory response, neurotoxicity, apoptosis and glial scarring, and further compromises neurological impairment after traumatic spinal cord injury. Edema, ischemia and loss of autoregulation continue to spread bi-directionally from the initial lesion along the spinal cord for up to 72 hours after the trauma.
It has been postulated that the damage caused by the primary injury mechanism is irreversible and therapeutic approaches in recent years have focused on modulating the secondary injury cascade.
Researchers found significantly greater numbers of myelinated fibers in peripheral nerves after a single ESWT application in an experimental model on rats after a homotopic nerve autograft into the sciatic nerve.
In another study a spinal cord ischemia model in mice was performed. ESWT was applied immediately after surgery and the treated animals showed a significantly better motor function and decreased neuronal degeneration compared to the control group within the first 7 days after surgery.
Researchers investigated the effect of low-energy ESWT for the duration of three weeks on a thoracic spinal cord contusion injury model in rats. Animals in the ESWT group demonstrated significantly better locomotor improvement and reduced neuronal loss compared to the control animals at 7, 35, and 42 days after contusion.
It has been postulated previously, that ESWT improves the metabolic activity of various cell types and induces an improved rate of axonal regeneration.
ESWT might be a promising therapeutic strategy in the treatment of traumatic SCI.
The underlying study aims to investigate the effect of ESWT after acute traumatic spinal cord injury in humans within 48 hours of trauma in order to intervene in the secondary injury phase with the objective to reduce the extent of neuronal damage.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: ESWT
The extracorporeal shockwave therapy is applied once at the level of lesion and 5 segments above and below; or below the occiput (in lesions higher than C6) and above the sacrum (in lesions lower than T12).
In addition, the ESWT is applied to the soles of both feet on the medial side of the plantar surface.
The ESWT is applied as soon as possible within 48 hours post-injury.
|
The shockwave generator orthogold 100® generates high-energy acoustic waves that behave much like other sound waves except that they have much greater pressure and energy.
As with sound waves, Spark Waves® can easily travel great distance as long as the acoustic impedance stays the same.
|
Sham Comparator: Control
In the control group, the same procedure is performed, but without the device emitting extracorporeal shock waves using a dummy head.
|
The shockwave generator orthogold 100® will be used in combination with a dummy head, to Refrain shock waves
|
