MS Spasticity
There are approximately 500,000 people with MS in Europe. Spasticity (spasms and stiffness) is one of the most common symptoms of MS occurring in as many as three quarters of people with MS. Spasticity can affect many aspects of daily life, such as walking and sitting.

The difference between Sativex and placebo was also highly significant for a number of secondary endpoints, including the 30% responder analysis (p=0.0003), spasm frequency (p=0.005), sleep disturbance (p
