Ankle clonus- MedGen UID:
- 68672
- •Concept ID:
- C0238651
- •
- Finding
Clonus is an involuntary tendon reflex that causes repeated flexion and extension of the foot. Ankle clonus is tested by rapidly flexing the foot upward.
Absent patellar reflexes- MedGen UID:
- 643630
- •Concept ID:
- C0558844
- •
- Finding
Absence of the knee jerk reflex, which can normally be elicited by tapping the patellar tendon with a reflex hammer just below the patella.
Dysarthria- MedGen UID:
- 8510
- •Concept ID:
- C0013362
- •
- Mental or Behavioral Dysfunction
Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.
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.
Spasticity- MedGen UID:
- 7753
- •Concept ID:
- C0026838
- •
- Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Babinski sign- MedGen UID:
- 19708
- •Concept ID:
- C0034935
- •
- Finding
Upturning of the big toe (and sometimes fanning of the other toes) in response to stimulation of the sole of the foot. If the Babinski sign is present it can indicate damage to the corticospinal tract.
Hyperreflexia- MedGen UID:
- 57738
- •Concept ID:
- C0151889
- •
- Finding
Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.
Spastic gait- MedGen UID:
- 115907
- •Concept ID:
- C0231687
- •
- Finding
Spasticity is manifested by increased stretch reflex which is intensified with movement velocity. This results in excessive and inappropriate muscle activation which can contribute to muscle hypertonia. Spastic gait is characterized by manifestations such as muscle hypertonia, stiff knee, and circumduction of the leg.
Hoffmann sign- MedGen UID:
- 78828
- •Concept ID:
- C0277839
- •
- Sign or Symptom
A Hoffmann test is performed by flicking the fingernail of the long finger, from dorsal to volar, on each hand while the hand was supported by the examiner's hand. The test was done with the neck in the neutral position and then with the neck maximally forward flexed. Any flexion of the ipsilateral thumb and/or index finger was interpreted as a positive test.
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.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk.
Lower limb spasticity- MedGen UID:
- 220865
- •Concept ID:
- C1271100
- •
- Finding
Spasticity (velocity-dependent increase in tonic stretch reflexes with increased muscle tone and hyperexcitable tendon reflexes) in the muscles of the lower limbs, hips, and pelvis.
Lower limb hyperreflexia- MedGen UID:
- 322973
- •Concept ID:
- C1836696
- •
- Finding
Abnormal cerebellum morphology- MedGen UID:
- 400925
- •Concept ID:
- C1866129
- •
- Anatomical Abnormality
Any structural abnormality of the cerebellum.
Muscular atrophy- MedGen UID:
- 892680
- •Concept ID:
- C0541794
- •
- Pathologic Function
The presence of skeletal muscular atrophy (which is also known as amyotrophy).
Thoracic scoliosis- MedGen UID:
- 387910
- •Concept ID:
- C1857790
- •
- Anatomical Abnormality
- Abnormality of limbs
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
