Ankle flexion contracture- MedGen UID:
- 332440
- •Concept ID:
- C1837407
- •
- Anatomical Abnormality
A chronic loss of ankle joint motion due to structural changes in muscle, tendons, ligaments, or skin that prevent normal movement of the joints of the ankle.
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk. In general, this can refer to neurological diseases but also fractures or other sources of pain that is triggered upon walking. However, in the current context gait disturbance refers to difficulty walking on the basis of a neurological or muscular disease.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078
- •
- Finding
Reduction of neurologic reflexes such as the knee-jerk reaction.
Axonal loss- MedGen UID:
- 316962
- •Concept ID:
- C1832338
- •
- Finding
A reduction in the number of axons in the peripheral nervous system.
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 nerve conduction velocity- MedGen UID:
- 347509
- •Concept ID:
- C1857640
- •
- Finding
A reduction in the speed at which electrical signals propagate along the axon of a neuron.
Decreased motor nerve conduction velocity- MedGen UID:
- 388130
- •Concept ID:
- C1858729
- •
- Finding
A type of decreased nerve conduction velocity that affects the motor neuron.
Peripheral hypomyelination- MedGen UID:
- 870480
- •Concept ID:
- C4024927
- •
- Finding
Reduced amount of myelin in the nervous system resulting from defective myelinogenesis in the peripheral nervous system.
Distal arthrogryposis- MedGen UID:
- 120512
- •Concept ID:
- C0265213
- •
- Disease or Syndrome
An inherited primary limb malformation disorder characterized by congenital contractures of two or more different body areas and without primary neurologic and/or muscle disease that affects limb function.
Distal muscle weakness- MedGen UID:
- 140883
- •Concept ID:
- C0427065
- •
- Finding
Reduced strength of the musculature of the distal extremities.
Frequent falls- MedGen UID:
- 163408
- •Concept ID:
- C0850703
- •
- Finding
- Abnormality of limbs
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
