“To examine evolution in activities of daily living (ADL) in patients with multiple sclerosis spasticity during long-term use of tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray.
Functional impairment was assessed retrospectively (prior to start of treatment) and at the present moment using a 16-item ADL survey; results were compared. A control group without add-on THC:CBD oromucosal spray was included to investigate possible recall bias.
ADL was maintained or slightly improved with THC:CBD oromucosal spray across treatment time (mean 31.9 months) including significant improvement in ‘standing up’ (p < 0.05) and trends in other items. Significant improvements (p < 0.01) with THC:CBD oromucosal spray were observed in several multiple sclerosis spasticity-related symptoms. Overall, 96.9% of patients using THC:CBD oromucosal spray had a positive global impression of change during treatment.
In this pilot study, THC:CBD oromucosal spray maintained or improved aspects of daily functioning. Further study in a larger trial is warranted.”
