Waddling gait- MedGen UID:
- 66667
- •Concept ID:
- C0231712
- •
- Finding
Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck.
Fatigable weakness- MedGen UID:
- 451076
- •Concept ID:
- C0947912
- •
- Disease or Syndrome
A type of weakness that occurs after a muscle group is used and lessens if the muscle group has some rest. That is, there is diminution of strength with repetitive muscle actions.
Easy fatigability- MedGen UID:
- 373253
- •Concept ID:
- C1837098
- •
- Finding
Increased susceptibility to fatigue.
Bulbar palsy- MedGen UID:
- 898626
- •Concept ID:
- C4082299
- •
- Disease or Syndrome
Bulbar weakness (or bulbar palsy) refers to bilateral impairment of function of the lower cranial nerves IX, X, XI and XII, which occurs due to lower motor neuron lesion either at nuclear or fascicular level in the medulla or from bilateral lesions of the lower cranial nerves outside the brain-stem. Bulbar weakness is often associated with difficulty in chewing, weakness of the facial muscles, dysarthria, palatal weakness and regurgitation of fluids, dysphagia, and dysphonia.
Muscle spasm- MedGen UID:
- 52431
- •Concept ID:
- C0037763
- •
- Sign or Symptom
Sudden and involuntary contractions of one or more muscles.
Gowers sign- MedGen UID:
- 65865
- •Concept ID:
- C0234182
- •
- Finding
A phenomenon whereby patients are not able to stand up without the use of the hands owing to weakness of the proximal muscles of the lower limbs.
Weakness of facial musculature- MedGen UID:
- 98103
- •Concept ID:
- C0427055
- •
- Disease or Syndrome
Reduced strength of one or more muscles innervated by the facial nerve (the seventh cranial nerve).
Axial muscle weakness- MedGen UID:
- 334472
- •Concept ID:
- C1843697
- •
- Finding
Reduced strength of the axial musculature (i.e., of the muscles of the head and neck, spine, and ribs).
Distal amyotrophy- MedGen UID:
- 338530
- •Concept ID:
- C1848736
- •
- Disease or Syndrome
Muscular atrophy affecting muscles in the distal portions of the extremities.
Proximal amyotrophy- MedGen UID:
- 342591
- •Concept ID:
- C1850794
- •
- Disease or Syndrome
Amyotrophy (muscular atrophy) affecting the proximal musculature.
Reduced vital capacity- MedGen UID:
- 141657
- •Concept ID:
- C0476408
- •
- Finding
An abnormal reduction on the vital capacity, which is defined as the total lung capacity (volume of air in the lungs at maximal inflation) less the residual volume (i.e., volume of air in the lungs following maximal exhalation) of the lung.
Respiratory insufficiency due to muscle weakness- MedGen UID:
- 812797
- •Concept ID:
- C3806467
- •
- Finding
Anti-acetylcholine receptor antibody positivity- MedGen UID:
- 868186
- •Concept ID:
- C4022578
- •
- Finding
The presence of autoantibodies (immunoglobulins) in the blood circulation that react against ganglioside-monosialic acid (GM1), which is a type of glycosphingolipid with one sialic acid. GM1 is located on the outer layer of the plasma membrane, and plays a vital role in neurogenesis, nerve development, differentiation and repair after injury.
Mildly elevated creatine kinase- MedGen UID:
- 342469
- •Concept ID:
- C1850309
- •
- Finding
Tongue atrophy- MedGen UID:
- 66828
- •Concept ID:
- C0241423
- •
- Finding
Wasting of the tongue.
Decreased fetal movement- MedGen UID:
- 68618
- •Concept ID:
- C0235659
- •
- Finding
An abnormal reduction in quantity or strength of fetal movements.
Ptosis- MedGen UID:
- 2287
- •Concept ID:
- C0005745
- •
- Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
Ophthalmoparesis- MedGen UID:
- 155551
- •Concept ID:
- C0751401
- •
- Sign or Symptom
Ophthalmoplegia is a paralysis or weakness of one or more of the muscles that control eye movement.
