27 Possible Causes for Electromyogram Abnormal, No Muscle Weakness, Positive Gower's Sign

  • Duchenne Muscular Dystrophy

    Muscle weakness Other names Myasthenia Specialty Neurology Muscle weakness is a lack of muscle strength.[] A physical examination revealed proximal muscle weakness, calf hypertrophy, deep tendon hyporflexia and a positive Gower's sign.[] The condition progresses rapidly and the child develops a waddling gait and a positive Gower's sign.[]

  • Muscular Dystrophy

    It causes progressive weakness in muscles of the face, arms, legs, and around the shoulders and chest.[] Boys with DMD demonstrate a positive Gowerssign, a maneuver used by individuals with proximal muscle weakness to rise from a seated position.[] ' sign.[]

  • Limb-Girdle Muscular Dystrophy

    However, most patients in the current family showed distal as well as proximal limb weakness rather than weakness of toe and finger flexor muscles that were typical features[] We report a Saudi Arabian family with weakness in limb-girdle distribution: waddling gait, positive Gowers' sign, and marked muscle atrophy in the shoulder and pelvic girdle[] Gower sign, and variable muscle cramps after exercise; Isolated hyperCKemia (i.e., elevated serum concentration of creatine kinase (CK) in the absence of signs of muscle[]

  • Becker Muscular Dystrophy

    […] changes in the structure of the muscle cells Tests that stain the muscle sample can be used to visualize any muscle proteins present Electromyogram (EMG): Another diagnostic[] Later symptoms Muscle weakness: Affects the proximal muscles of the limbs mainly.[] From age 27 years, he developed proximal muscle weakness predominantly of the lower limbs, a positive Gower sign, and a waddling gait.[]

  • Secondary Myopathy

    Although changes seen on electromyography are not pathognomonic for any specific disease process, an abnormal electromyogram can indicate if a neuropathy or neuromuscular[] Pelvic girdle Difficulty climbing stairs, waddling gait, difficulty rising to standing position from a squatting position (patient may demonstrate Gower sign), difficulty[] electromyograms, evocative muscle biopsy and an abnormal signal on muscle magnetic resonance imaging.[]

  • Dermatomyositis

    (EMG) which can demonstrate abnormal electrical activity in muscles and help distinguish weakness due to muscle disease from weakness due to nerve problems A nerve conduction[] Symptoms may include: Muscle weakness, stiffness, or soreness Problems swallowing Purple color to the upper eyelids Purple-red skin rash Shortness of breath The muscle weakness[] (i.e., Gower's sign).[]

  • Myopathy

    Electroencephalographic abnormalities have been noted in several patients with the early-onset form of the disease before clinically apparent seizure activity begins.[] Muscle weakness regressed and dysphagia disappeared with treatment.[] He had a waddling gait, a positive Gowers' sign, and he was barely able to run.[]

  • Childhood Dermatomyositis

    (EMG) which can demonstrate abnormal electrical activity in muscles and help distinguish weakness due to muscle disease from weakness due to nerve problems X-rays of the[] In a second flare in childhood, she developed proximal muscle weakness and calcinosis cutis. A muscle biopsy was consistent with juvenile dermatomyositis.[] (i.e., Gower's sign).[]

  • Oculopharyngeal Muscular Dystrophy

    The effect of BCL2 co-expression on muscle weakness is transient, since muscle weakness is apparent in mice expressing both A17 and BCL2 transgenes at late time points.[] In Gower’s sign, the person finds it difficult to get up from sitting position and hence first raises the thighs and the hip such that the person is half bent over and then[] Genetically blocking apoptosis by over-expressing BCL2 ameliorates muscle weakness in our mouse model of OPMD (A17 mice).[]

  • Central Core Disease

    The electromyogram showed myopathic pattern. Muscle biopsy revealed type 1 fiber atrophy and central core abnormalities.[] The presence of an alternate mechanism of muscle weakness in CCD is supported by the observation that muscle cells expressing a CCD mutation in the putative pore-forming segment[] On physical examination, she had a high-arched palate, nasal tone vocalization, a positive Gowers' sign, waddling gait, and decreased deep tendon reflexes.[]
