Symptom 3: Rigidity – Stiffness and Muscle Tension in Parkinson’s Disease
Rigidity in Parkinson’s disease is akin to an unwelcome guest, imposing a stiffness and inflexibility that take a toll on the body’s grace and ease of movement. It usually appears unilaterally, similar to tremors, eventually spreading to encompass the entire body.
Within the confines of rigidity, muscles resist passive movement, leading to a sensation of stiffness. This aspect manifests in various ways – simple gestures, such as waving or nodding, suddenly feel akin to moving through dense, unseen molasses.
The unique characteristic of rigidity in Parkinson’s is the ‘lead-pipe’ and ‘cogwheel’ rigidity. The former refers to uniform resistance throughout the range of movement, while the latter combines the stiffness of rigidity with the rhythmic interruptions of tremors. This ‘cogwheel’ rigidity is a distinct sign of Parkinson’s, setting it apart from other neurological conditions.
Beyond the physical, rigidity can prove to be a psychological burden, bringing with it a frustrating loss of independence. Everyday tasks, once done effortlessly, now necessitate help, leading to a struggle with feelings of helplessness and dependency. (3)
