Rigidity
Parkinson’s disease can cause changes in a person’s movement patterns. One specific change that may occur is a decrease in arm swinging while walking. This change could be a symptom of the disease. Rigidity, which is characterized by tightness or stiffness in the limbs or torso, is a common manifestation of Parkinson’s. Unlike normal muscle contraction and relaxation, the muscles remain tense, restricting the free movement of the arms. In some cases, rigidity is misdiagnosed as arthritis or an orthopedic injury during the early stages of Parkinson’s.
Understanding Bradykinesia
Bradykinesia, also known as slowness of movement, is one of the primary motor symptoms associated with certain diseases. This condition occurs when the brain becomes slow in transmitting instructions to the body, resulting in a gradual reduction in spontaneous movement.
Individuals with bradykinesia may experience various manifestations of this symptom. For instance, their eyes may blink at a slower rate, giving the impression of delayed reactions. Additionally, their facial expressions might appear mask-like, lacking the usual range of movements. Simple tasks that require fine motor skills, such as buttoning a shirt, may become challenging.
Some individuals with bradykinesia may also encounter a phenomenon called freezing of gait. This sensation makes them feel as if they are glued to the floor, unable to take steps forward. Not only does this condition affect their balance, but it also hampers their ability to walk smoothly.
