Symptom 2: Motor Impairments
Motor impairments are another key facet of MSA, often manifesting in distinct ways across the disease’s progression. Patients typically experience a gradual decline in their motor functions, ranging from difficulties with balance and coordination to pronounced muscle rigidity.
One of the most apparent signs of motor impairment in MSA is an unsteady gait. Individuals often report a sense of imbalance, as though they’re perpetually on the verge of toppling over. This unsteadiness can escalate into frequent falls, a symptom that not only compromises patients’ mobility but also exposes them to a heightened risk of injuries.
In addition to balance issues, muscle rigidity or stiffness is another common manifestation. Patients may find their movements growing increasingly rigid, with a marked reduction in their range of motion. This rigidity can affect any part of the body, but it’s particularly evident in the limbs.
Motor impairments also give rise to bradykinesia, a medical term referring to a notable slowing down of physical movement. Patients may find it challenging to initiate movements or perform routine tasks, with their motions appearing unusually slow and laborious. (2)
