- C0728829
- •
- Congenital Abnormality
An increase in height of the medial longitudinal arch of the foot that does not flatten on weight bearing (i.e., a distinctly hollow form of the sole of the foot when it is bearing weight).
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Sensory ataxia- MedGen UID:
- 66020
- •Concept ID:
- C0240991
- •
- Sign or Symptom
Incoordination of movement caused by a deficit in the sensory nervous system. Sensory ataxia can be distinguished from cerebellar ataxia by asking the patient to close his or her eyes. Persons with cerebellar ataxia show only a minimal worsening of symptoms, whereas persons with sensory ataxia show a marked worsening of symptoms.
Steppage gait- MedGen UID:
- 98105
- •Concept ID:
- C0427149
- •
- Finding
An abnormal gait pattern that arises from weakness of the pretibial and peroneal muscles due to a lower motor neuron lesion. Affected patients have footdrop and are unable to dorsiflex and evert the foot. The leg is lifted high on walking so that the toes clear the ground, and there may be a slapping noise when the foot strikes the ground again.
Gait ataxia- MedGen UID:
- 155642
- •Concept ID:
- C0751837
- •
- Sign or Symptom
A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.
Broad-based gait- MedGen UID:
- 167799
- •Concept ID:
- C0856863
- •
- Finding
An abnormal gait pattern in which persons stand and walk with their feet spaced widely apart. This is often a component of cerebellar ataxia.
Peripheral demyelination- MedGen UID:
- 451074
- •Concept ID:
- C0878575
- •
- Pathologic Function
A loss of myelin from the internode regions along myelinated nerve fibers of the peripheral nervous system.
Loss of ambulation- MedGen UID:
- 332305
- •Concept ID:
- C1836843
- •
- Finding
Inability to walk in a person who previous had the ability to walk.
Distal sensory impairment- MedGen UID:
- 335722
- •Concept ID:
- C1847584
- •
- Finding
An abnormal reduction in sensation in the distal portions of the extremities.
Onion bulb formation- MedGen UID:
- 376237
- •Concept ID:
- C1847906
- •
- Finding
Repeated episodes of segmental demyelination and remyelination lead to the accumulation of supernumerary Schwann cells around axons, which is referred to as onion bulb formation. This finding affects peripheral nerves.
Motor delay- MedGen UID:
- 381392
- •Concept ID:
- C1854301
- •
- Finding
A type of Developmental delay characterized by a delay in acquiring motor skills.
Decreased number of peripheral myelinated nerve fibers- MedGen UID:
- 346872
- •Concept ID:
- C1858285
- •
- Finding
A loss of myelinated nerve fibers in the peripheral nervous system (in general, this finding can be observed on nerve biopsy).
Decreased motor nerve conduction velocity- MedGen UID:
- 388130
- •Concept ID:
- C1858729
- •
- Finding
A type of decreased nerve conduction velocity that affects the motor neuron.
Decreased number of large peripheral myelinated nerve fibers- MedGen UID:
- 395303
- •Concept ID:
- C1859606
- •
- Finding
A reduced number of large myelinated nerve fibers.
Basal lamina onion bulb formation- MedGen UID:
- 401045
- •Concept ID:
- C1866637
- •
- Finding
A type of onion bulb formation prominently affecting the area of the basal lamina.
Scoliosis- MedGen UID:
- 11348
- •Concept ID:
- C0036439
- •
- Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
Difficulty walking- MedGen UID:
- 86319
- •Concept ID:
- C0311394
- •
- Finding
Reduced ability to walk (ambulate).
Distal muscle weakness- MedGen UID:
- 140883
- •Concept ID:
- C0427065
- •
- Finding
Reduced strength of the musculature of the distal extremities.
Muscular atrophy- MedGen UID:
- 892680
- •Concept ID:
- C0541794
- •
- Pathologic Function
The presence of skeletal muscular atrophy (which is also known as amyotrophy).
Distal amyotrophy- MedGen UID:
- 338530
- •Concept ID:
- C1848736
- •
- Disease or Syndrome
Muscular atrophy affecting muscles in the distal portions of the extremities.
Enlarged cisterna magna- MedGen UID:
- 344031
- •Concept ID:
