Micrographia(also: Small Handwriting)

A condition characterized by abnormally small, cramped handwriting that often becomes progressively smaller within a line or paragraph. Micrographia is a common early sign of Parkinson's Disease, resulting from the same motor control difficulties that cause bradykinesia. The…

Motor Disability(also: Motor Impairment, Physical Disability, Movement Disorder)

A condition that affects a person's ability to control voluntary muscle movements, impacting mobility, dexterity, coordination, or speech production. Motor disabilities can result from neurological conditions (cerebral palsy, ALS, multiple sclerosis), spinal cord injuries,…

Motor Fluctuation(also: On-Off Phenomenon, Wearing Off, On-Off Periods)

Variations in motor function experienced by people with Parkinson's Disease, typically related to medication timing. During 'on' periods when medication is working optimally, motor symptoms are controlled; during 'off' periods as medication wears off, symptoms like tremor,…

Motor Neuron Disease(also: MND, ALS, Amyotrophic Lateral Sclerosis)

A group of progressive neurological disorders that destroy motor neurons, the cells controlling voluntary muscle activity including speaking, walking, breathing, and swallowing. ALS (amyotrophic lateral sclerosis) is the most common form. As the disease progresses, people lose…

Multimodal Cueing

Multimodal cueing is the simultaneous or selectable use of two or more sensory channels - typically visual, auditory, and somatosensory (vibrotactile) - to guide motor behaviour during rehabilitation or assistive interaction. The rationale is that different modalities engage…

Muscular Dystrophy(also: MD)

A group of inherited genetic conditions that cause progressive weakness and loss of muscle mass, affecting mobility, upper limb function, and in some forms, respiratory and cardiac function. People with muscular dystrophy often rely on electric wheelchairs for mobility and may…

Muscular Dystrophy(also: MD)

A group of inherited genetic conditions that cause progressive weakness and degeneration of skeletal muscles, the muscles that control movement. There are many types of muscular dystrophy varying in severity, age of onset, and which muscles are affected. Because muscular…

Myopathy(also: Muscle Disease)

A group of disorders affecting skeletal muscle function, characterized by muscle weakness, cramping, stiffness, or wasting. Myopathies can be inherited (muscular dystrophies) or acquired (inflammatory myopathies, metabolic myopathies). For digital accessibility, people with…
