142 Possible Causes for Bilateral Arm Weakness, Muscle Weakness

  • Duchenne Muscular Dystrophy

    Occasionally, however, females who carry a DMD gene mutation may have muscle weakness and cramping.[] Generally, proximal muscle weakness is noticed earlier followed by distal muscle weakness.[] Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy).[]

  • Multifocal Motor Neuropathy

    Her disease was difficult to manage with various immunosuppressants, and the muscle weakness eventually progressed to involve the respiratory muscles, necessitating mechanical[] Most patients showed not only muscle weakness but also fatigue, limited dexterity, and limited walking ability.[] The initial high-dose intravenous immunoglobulin treatment significantly improved left upper limb muscle weakness.[]

  • Erb Muscular Dystrophy

    Weakness is generally asymmetric and may spare the deltoid, supraspinatus, and infraspinatus muscles.[] Muscle weakness may spread from the proximal muscles to affect distal muscles.[] It causes progressive weakness in muscles of the face, arms, legs, and around the shoulders and chest.[]

  • Brachial Plexus Neuritis

    Brachial plexus neuritis is thought to be an immune mediated inflammatory reaction resulting in acute onset of shoulder pain followed by muscle weakness and wasting.[] Within a few hours or days of the condition’s onset, affected individuals may experience muscle weakness, wasting (atrophy), numbness (hyperesthesia), and paralysis of the[] Clinical features include severe pain in the shoulder region which may be accompanied by MUSCLE WEAKNESS and loss of sensation in the upper extremity.[]

  • Glycogen Storage Disease Type 2

    Dyspnea secondary to diaphragm or respiratory muscle weakness may also be observed.[] Infants with this disorder typically experience muscle weakness (myopathy), poor muscle tone (hypotonia), an enlarged liver (hepatomegaly), and heart defects.[] Here, glycogen accumulation mainly affects the heart and skeletal muscles, and affected infants develop progressive cardiomyopathy and muscle weakness.[]

  • Lambert Eaton Myasthenic Syndrome

    Results: in myasthenia gravis, initial weakness involved extraocular muscles in 59%, bulbar muscles in 29%, and limb muscles in 12% of the patients.[] The muscle weakness often improves with physical exercise, which distinguishes this syndrome from myasthenia.[] In contrast, a significant portion of patients with MG never progress past weakness in the extraocular muscles.[]

  • Hereditary ATTR Amyloidosis

    ., neuropathic pain, alternation sensation [sensitivity to pain and temperature], numbness and tingling, muscle weakness, impaired balance, difficulty walking) Autonomic dysfunction[] weakness.[] Buildup of amyloid in the heart muscle can cause weakness and lead to heart failure and death. In some cases, people may also experience nerve pain.[]

  • Amyotrophic Lateral Sclerosis

    Here, we report a patient who presented with progressive left arm weakness and was found to have bilateral MRI plexus abnormalities.[] Regionally isolated variants of ALS include flail arm syndrome, which involves bilateral proximal and typically predominant LMN arm weakness, and the flail leg syndrome, characterized[] Respiratory muscle weakness and failure is a common complication late in the course of disease.[]

  • Cervical Spondylosis

    We found 19 patients with weakness and atrophy of the intrinsic hand muscles, and 13 patients with weakness proximal to the hand muscles to serve as a control group.[] Muscle weakness makes it hard to lift the arms or grasp objects firmly.[] The pain might increase when: standing sitting sneezing coughing tilting your neck backward Another common symptom is muscle weakness.[]

  • Polymyalgia Rheumatica

    Shoulder, hip, neck and upper arm pain associated with PMR is usually bilateral and symmetrical.[] There is no true muscle weakness nor evidence of muscle disease on electromyography (EMG) or on biopsy.[] Radial pulses were normal and equal bilaterally, blood pressure was 110/70 mmHg in both arms. There were two small lymph nodes (1cm in diameter) in the left axilla.[]
