3,342 Possible Causes for EMG Shows Evidence of Reinnervation, Limb Weakness, Muscle Biopsy Abnormal

  • Motor Neuron Disease

    For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and[en.wikipedia.org] The results of electromyography and muscle biopsy were compatible with ALS. However, supranuclear vertical gaze palsy and slow saccades are seen.[ncbi.nlm.nih.gov] Selective distal upper limb muscle weakness and atrophy with non-significant lower limb weakness during follow-up was the most frequent motor pattern, present in 18 patients[ncbi.nlm.nih.gov]

  • Muscular Dystrophy

    This condition is typically characterized by large and abnormally distributed mitochondria on muscle biopsy, which can distinguish this condition from the other muscle conditions[ncbi.nlm.nih.gov] The symptoms of FSH dystrophy may appear during childhood with severe facial and limb weakness or develop slowly and gradually in adulthood with progressive difficulty closing[kennedykrieger.org] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu]

  • Duchenne Muscular Dystrophy

    Diagnosis of Duchenne Muscular Dystrophy A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle[disabled-world.com] And 2) are these gait deviations related to lower limb weakness?[ncbi.nlm.nih.gov] […] fibers) For Duchenne and Becker muscular dystrophies, muscle biopsy may show whether dystrophin, a muscle protein, is missing or abnormal, and DNA testing is used to analyze[webmd.com]

  • Limb-Girdle Muscular Dystrophy

    Muscle biopsy abnormalities in two individuals very early in the course of their disease suggest that biopsy would probably be useful in detection of preclinical disease in[pediatrics.aappublications.org] Limb-girdle muscular dystrophies (LGMD) are a group of clinically and genetically heterogeneous diseases characterized by weakness and wasting of the pelvic and shoulder girdle[ncbi.nlm.nih.gov] Some LGMD subtypes have distinguishing features, including pattern of muscle involvement, cardiac abnormalities, extramuscular involvement, and muscle biopsy findings.[ncbi.nlm.nih.gov]

  • Myopathy

    Clinical presentation, abnormal secretion of the collagen demonstrated in muscle biopsy and the COL6A1 c.1056 3A C mutation justify classification of the presented case as[ncbi.nlm.nih.gov] A 47-year-old man with liver cirrhosis developed limb weakness after liver transplantation.[ncbi.nlm.nih.gov] Laing early onset distal myopathy: slow myosin defect with variable abnormalities on muscle biopsy. J Neurol Neurosurg Psychiatry. 2006;77:208-15.[rarediseases.org]

  • Facioscapulohumeral Muscular Dystrophy

    If genetic testing does not confirm the diagnosis, then muscle biopsy can be done.[merckmanuals.com] FSHD presentation with foot drop or lower limb proximal weakness appeared to be more frequent than expected.[ncbi.nlm.nih.gov] […] distal (22.45 %) or proximal lower limb weakness (14.8 %). 85.57 % patients were ambulant or ambulant with assistance at the time of registration, 7.9 % report respiratory[ncbi.nlm.nih.gov]

  • Adult Spinal Muscular Atrophy

    Muscle biopsy- reveals evidence of devervation with no other structural abnormalities.[en.wikibooks.org] As the disease progresses patients may notice limb weakness starting in the pelvis or shoulders, or weakness of the facial and tongue muscles.[cedars-sinai.edu] In some situations other tests such as an EMG electromyography (EMG) or muscle biopsy may be needed because it is not possible to conduct the SMN gene tests or no abnormality[genome.gov]

  • Glycogen Storage Disease Type 2

    A muscle tissue biopsy may be assayed for muscle glycogen phosphorylase enzyme activity.[encyclopedia.com] An intermediate form manifests with muscle weakness in childhood. In the adult form, the patient may have limb-girdle weakness.[emedicine.medscape.com] weakness respiratory issues Enzyme replacement therapy alglucosidase alfa Cori disease (type III) Glycogen debranching enzyme Autosomal recessive Most cases involve the muscle[medbullets.com]
