Distal myopathy. Red depicts the preferentially affected areas in distal myopathy. Distal myopathy is a group of rare genetic disorders that cause muscle damage and weakness, predominantly in the hands and/or feet. Mutation of many different genes can be causative. Many types involve dysferlin.
Muscle weakness is a lack of muscle strength. Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such ...
Muscular dystrophies (MD) are a genetically and clinically heterogeneous group of rare neuromuscular diseases that cause progressive weakness and breakdown of skeletal muscles over time. [ 1 ] The disorders differ as to which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. [ 1 ]
Inclusion body myositis (IBM) (/ maɪoʊˈsaɪtɪs /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [ 2 ] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso) and distal muscles (close to ...
CMT is a peripheral neuropathy, affecting the distal muscles first as weakness, clumsiness, and frequent falls. It usually affects the feet first, but can sometimes begin in the hands. Charcot-Marie-Tooth disease can cause painful foot deformities such as pes cavus.
ALS is a motor neuron disease, which is a group of neurological disordersthat selectively affect motor neurons, the cells that control voluntary musclesof the body.[3] Other motor neuron diseases include primary lateral sclerosis(PLS), progressive muscular atrophy(PMA), progressive bulbar palsy, pseudobulbar palsy, and monomelic amyotrophy(MMA).
Various patterns of muscle weakness occur in different motor neuron diseases. [6] Weakness can be symmetric or asymmetric, and it can occur in body parts that are distal, proximal, or both. According to Statland et al., there are three main weakness patterns that are seen in motor neuron diseases, which are: [6] [9]
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
