Learning Objectives1. List two patient‐centered outcome measures that can be used to measure the 

burden of spasticity symptoms for Veterans with spinal cord injury or disorders.

2. Name three non‐pharmacologic/conservative treatment interventions for spasticity and explain when they should be implemented for patient care.

3. Explain the indications for spasticity management with botulinum toxin for Veterans with spinal cord injury or disorders.

Most persons with SCI/D have spasticity.

Chronic SCI (> 1 yr post‐injury):  65% (Holz, 2017)* “Problematic” spasticity 30‐40% 1‐5 years out

MS: up to 84% (Rizzo, 2004) patients with MS report some spasticity

ALS: 84% endorse “muscle stiffness” (Nicholson et al, 2017)

Classic definition from 1980 (Lance)Spasticity is a motor disorder characterized by a velocity dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitabilityof the stretch reflex, as one component of the upper motor neuron syndrome.

StretchingWhat is stretching:Elongation via applied tension to the soft‐tissue structures of muscle, tendon, connective, vascular, dermal and neural tissueThis tension and resulting elongation may change viscoelastic, structural and excitability properties in the stretched muscle 

Goal of stretching for spasticity:Normalize muscle tone, maintain or increase soft‐tissue extensibility, decrease pain, and improve function

JAMA Systematic ReviewEvaluated 11 randomized studies with a total of 2138 patients comparing the effect cannabinoids with placebo on spasticity related to MS. 

Although the specific details of the studies vary, most studies suggest that cannabinoids are associated with improvements in self‐reported spasticity.

The improvements in objectively measured spasticity generally do not reach statistical significance

Cannabinoids for spasticity in MS conclusionsDEA Schedule 1, not FDA approved in US

Data support that it works (reduces severity) for self‐reported spasticity

All RCT data is from oral or oromucosal spray preparations, not smoked cannabis

~50% seem to keep using, ~ 50% stop due to lack of efficacy or AEs

DoseVariesStart low and allow patients to self‐titrate upMost use ~ 20‐40mg THC/day in divided doses

Conclusions continuedCannabis is increasingly available to our patients with MS and there is growing interest in its use

Multiple forms and formulations are available

In multiple sclerosis, the best evidence for benefit is for reduction of patient reported spasticity, with ~ 50% of subjects reporting benefit

The risks in this population are likely similar to those in other populations

In addition, the most clearly specific risk in this population is worsening of cognition
