Variability of Multiple Sclerosis Spasticity Symptoms in Response to THC:CBD Oromucosal Spray: Tracking Cases through Clinical Scales and Video Recordings

Multiple sclerosis (MS) is an inflammatory and neurodegenerative autoimmune demyelinating disease of the central nervous system. Patients exhibit heterogeneous patterns of disabling symptoms, including spasticity. In the majority of patients with MS spasticity, it and its associated symptoms contribute to disability, interfere with performance of everyday activities, and impair quality of life. Even under treatment with oral antispasticity drugs, about a third of patients continue to experience spasticity of moderate to severe intensity, underscoring the need for additional treatment options. The efficacy of tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray as add-on therapy in patients with refractory MS spasticity has been demonstrated in clinical trials and observational studies. To gain insight into patients ’ response to treatment at the individual level, in-depth changes from baseline in various clinical scales and video-assessed parameters were evaluated in patients with resistant MS spasticity before and after 1 month of treatment with THC:CBD oromucosal spray. All 6 patients showed ≥20% improve ment in the spasticity Numerical Rating Scale (i.e., were initial responders to treatment), but displayed individual variability in other spasticity-related parameters. Improved Modified Ashworth Scale scores were observed in 5 cases, with a reduction of –2/–3 points in lower limb scores for 1 p atient who also showed benefit in terms of a more stable gait bu...
