- Disease or Syndrome
Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- or overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly).
Impaired vibratory sensation- MedGen UID:
- 220959
- •Concept ID:
- C1295585
- •
- Finding
A decrease in the ability to perceive vibration. Clinically, this is usually tested with a tuning fork which vibrates at 128 Hz and is applied to bony prominences such as the malleoli at the ankles or the metacarpal-phalangeal joints. There is a slow decay of vibration from the tuning fork. The degree of vibratory sense loss can be crudely estimated by counting the number of seconds that the examiner can perceive the vibration longer than the patient.
Impaired proprioception- MedGen UID:
- 346424
- •Concept ID:
- C1856691
- •
- Finding
A loss or impairment of the sensation of the relative position of parts of the body and joint position.
Reduced tendon reflexes- MedGen UID:
- 356648
- •Concept ID:
- C1866934
- •
- Finding
Diminution of tendon reflexes, which is an invariable sign of peripheral nerve disease.
Scoliosis- MedGen UID:
- 11348
- •Concept ID:
- C0036439
- •
- Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
