Botulinum Toxin A for the Treatment of Cervical/Shoulder Pain Following Acute Spinal Cord Injury.
In Brief
A Phase 4 clinical trial evaluating botulinum toxin A and placebo for Spinal Cord Injury and Pain. Completed, enrolled 19 participants across 1 site.
Detailed Summary
As clinicians, it is often a struggle to find effective pain control for a certain subgroup of patients with tetraplegia. These patients often have severe upper back, neck, and shoulder pain, limiting rehabilitation productivity and potential, and always limiting quality of life. This pain appears to be primarily musculoskeletal. Muscles in the upper back and neck become shortened, rock hard, and extremely tender with even the slightest touch or stretch. Refractory to multiple classes of medications, modalities, and other treatments, patients truly suffer-not only from pain, but from fatigue, sedation, expense, and loss of useful rehabilitation time due to attempted remedies. Unfortunately, this subgroup of patients is not small and the problem is significant, as anyone who specializes in the treatment of spinal cord injury patients will recognize. In search for another form of treatment, botulinum toxin A (BTXA) may be promising for pain control in that group of patients with tetraplegia whose pain has proven to be refractory to treatment. It did not take long searching the literature to find compelling evidence that BTXA may have another mechanism of action for direct pain control, apart from its well known mechanism for spasticity control. Clinically, it is increasingly being recommended and used for this purpose. In fact, one of the specific indications now recognized by most for BTXA treatment is for myogenic pain due to short, tight, strained muscles-just as we see with our population. Yet, it's application has not been studied in people with tetraplegia. Thus, the genesis of the project and the hope to help our patients evolved. Study hypotheses: * In addition to traditional treatments used for pain control, injection of BTXA into cervical and upper back muscles will effectively reduce cervical/shoulder pain severity reported by individuals with cervical spinal cord injuries, regardless of the etiology of pain. * Pain reduction secondary to the use of BTXA will be associated with a decrease in total analgesic medication use among SCI patients during acute inpatient rehabilitation. * BTXA to treat cervical/shoulder pain will increase active participation in the rehabilitation program for individuals with tetraplegia during inpatient rehabilitation.

Timeline
Interventions
Injection of BTXA into cervical and upper back muscles based on treatment plan prescribed for each participant individually based on muscle soreness and tightness. Injections occured on one single clinic visit.Both the saline and BTXA were dosed in 25 cc syringes and looked the same for the physician performing the injections to ensure both participant and study physician remained blinded.
Injection of normal saline into cervical and upper back muscles was also based on treatment plan prescribed for each participant individually based on muscle soreness and tightness. Injections occured on one single clinic visit. Both the saline and BTXA were dosed in 25 cc syringes and looked the same for the physician performing the injections to ensure both participant and study physician remained blinded.
