What is muscle rigidity associated with?

Muscle rigidity is commonly associated with stiffness and pain that is often a result of various neuromuscular conditions. This phenomenon can occur in disorders such as Parkinson's disease, multiple sclerosis, and certain types of dystonia. In these conditions, the normal muscle control mechanisms become disrupted, leading to increased resistance to passive movement, thus causing the characteristic stiffness. Patients frequently report pain as a result of this rigidity, which can affect range of motion and overall function. Understanding this connection helps trainers and healthcare professionals recognize symptoms of underlying neuromuscular issues, enabling them to tailor fitness programs that accommodate these challenges, ultimately promoting inclusivity and safety in exercise settings.
