Pes cavus- MedGen UID:
- 675590
- •Concept ID:
- 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).
Hammertoe- MedGen UID:
- 209712
- •Concept ID:
- C1136179
- •
- Anatomical Abnormality
Hyperextension of the metatarsal-phalangeal joint with hyperflexion of the proximal interphalangeal (PIP) joint.
Foot dorsiflexor weakness- MedGen UID:
- 356163
- •Concept ID:
- C1866141
- •
- Finding
Weakness of the muscles responsible for dorsiflexion of the foot, that is, of the movement of the toes towards the shin. The foot dorsiflexors include the tibialis anterior, the extensor hallucis longus, the extensor digitorum longus, and the peroneus tertius muscles.
Fasciculations- MedGen UID:
- 5124
- •Concept ID:
- C0015644
- •
- Sign or Symptom
Fasciculations are observed as small, local, involuntary muscle contractions (twitching) visible under the skin. Fasciculations result from increased irritability of an axon (which in turn is often a manifestation of disease of a motor neuron). This leads to sporadic discharges of all the muscle fibers controlled by the axon in isolation from other motor units.
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Tip-toe gait- MedGen UID:
- 98104
- •Concept ID:
- C0427144
- •
- Finding
An abnormal gait pattern characterized by the failure of the heel to contact the floor at the onset of stance during gait.
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.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078
- •
- Finding
Reduction of neurologic reflexes such as the knee-jerk reaction.
Axonal degeneration- MedGen UID:
- 332464
- •Concept ID:
- C1837496
- •
- Finding
Distal sensory impairment- MedGen UID:
- 335722
- •Concept ID:
- C1847584
- •
- Finding
An abnormal reduction in sensation in the distal portions of the extremities.
Impaired distal vibration sensation- MedGen UID:
- 381262
- •Concept ID:
- C1853767
- •
- Finding
A decrease in the ability to perceive vibration in the distal portions of the limbs.
Decreased motor nerve conduction velocity- MedGen UID:
- 388130
- •Concept ID:
- C1858729
- •
- Finding
A type of decreased nerve conduction velocity that affects the motor neuron.
Axonal degeneration/regeneration- MedGen UID:
- 368889
- •Concept ID:
- C1968790
- •
- Finding
A pattern of simultaneous degeneration and regeneration of axons (see comment).
Peripheral axonal degeneration- MedGen UID:
- 871339
- •Concept ID:
- C4025830
- •
- Finding
Progressive deterioration of peripheral axons.
Distal muscle weakness- MedGen UID:
- 140883
- •Concept ID:
- C0427065
- •
- Finding
Reduced strength of the musculature of the distal extremities.
Distal amyotrophy- MedGen UID:
- 338530
- •Concept ID:
- C1848736
- •
- Disease or Syndrome
Muscular atrophy affecting muscles in the distal portions of the extremities.
- Abnormality of limbs
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
