13 Possible Causes for Difficulty Rising from a Squatting Position, Electromyogram Abnormal

  • 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[aafp.org] Pelvic girdle Difficulty climbing stairs, waddling gait, difficulty rising to standing position from a squatting position (patient may demonstrate Gower sign), difficulty[sites.google.com] electromyograms, evocative muscle biopsy and an abnormal signal on muscle magnetic resonance imaging.[err.ersjournals.com]

  • 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[mda.org.au] Patients may have difficulty rising from a chair or squatting and then raising themselves from this position.[emedicine.medscape.com] […] are usually normal or show only minimal abnormalities.[thedoctorsdoctor.com]

  • Inclusion Body Myositis

    Inclusion body myositis is associated with a modest degree of creatine kinase (CK) elevation and an abnormal electromyogram demonstrating an irritative myopathy with some[pesquisa.bvsalud.org] The most common reasons for presentation are related to weakness of the quadriceps muscles, such as difficulty rising from low chairs or from the squatting or kneeling positions[ibmmyositis.com]

  • Neuromuscular Junction Disorder

    One maneuver that may demonstrate weakness is to have the patient squat down and rise to the standing position without any assistance from their arms.[ahcmedia.com] Normally, most patients without weakness are able to rise with only minor difficulty.[ahcmedia.com]

  • Polyglucosan Body Myopathy Type 2

    Nerve conduction velocity and electromyogram reveal an axonal lumbosacral polyradiculoneuropathy.[ncbi.nlm.nih.gov] Pelvic girdle Difficulty climbing stairs, waddling gait, difficulty rising to standing position from a squatting position (patient may demonstrate Gower sign), difficulty[sites.google.com] Electrophysiologic testing is nonspecific: Specialized autonomic testing (thermoregulatory sweat tests and autonomic reflex testing) shows sudomotor sweating abnormalities[ncbi.nlm.nih.gov]

  • Myoadenylate Deaminase Deficiency

    The electromyogram showed myopathic abnormalities in the biceps, it was normal in quadriceps and anterior tibial muscles. A quadriceps muscle biopsy was performed.[ncbi.nlm.nih.gov] Pelvic girdle Difficulty climbing stairs, waddling gait, difficulty rising to standing position from a squatting position (patient may demonstrate Gower sign), difficulty[sites.google.com] There was no weakness nor any other abnormality at the neurological examination. The serum creatine phosphokinase activity was elevated three times out of four.[ncbi.nlm.nih.gov]

  • Juvenile Myasthenia Gravis

    An EMG/NCS can detect abnormal electrical muscle activity due to diseases and neuromuscular conditions.[stanfordchildrens.org] When generalized muscle weakness is there, patients have problems to walk a normal distance or to run, have difficulties in climbing stairs or to rise from a squatting position[lupinepublishers.com] The mainstay of the diagnosis of MG is through the performance of an electromyogram/nerve conduction study (EMG/NCS), which is a test that measures the electrical activity[stanfordchildrens.org]
