B. Cyclobenzaprine is a muscle relaxant, and its effectiveness is indicated by a reduction in muscle rigidity and spasms, along with improved range of motion.
C. Physical dependence is not a goal of treatment with cyclobenzaprine. The effectiveness of the medication should be measured by symptom relief, not dependence.
