How do you test for Dysdiadochokinesia?
Dysdiadochokinesia is demonstrated clinically by asking the patient to tap the palm of one hand with the fingers of the other, then rapidly turn over the fingers and tap the palm with the back of them, repeatedly. This movement is known as a pronation/supination test of the upper extremity.
How do you test rapid alternating movements?
Ask the patient to place their hands on their thighs and then rapidly turn their hands over and lift them off their thighs. Once the patient understands this movement, tell them to repeat it rapidly for 10 seconds. Normally this is possible without difficulty. This is considered a rapidly alternating movement.

- Heel-to-shin test. This test requires you to lie down and bring your heel to the top of the opposite shin.
- Imaging tests.
- Genetic tests.
How do you measure lower limb coordination?
The following are neurological co-ordination tests in the lower limb:
- heel shin test.
- toe finger test.
- rapidly alternating movements, e.g. tap the examiner’s hand with the sole of his foot as quickly as possible.
How would you describe an abnormal finger to nose test?
Finger to nose & finger to finger test You increase the difficulty of this test by adding resistance to the patient’s movements or move your finger to different locations. Abnormality of this is called dysmetria.

What does dysmetria mean?
Dysmetria is a condition in which there is improper measuring of distance in muscular acts; hypermetria is overreaching (overstepping) and hypometria is underreaching (understepping). Tremor refers to an involuntary, rhythmic, oscillatory movement of a body part.
What tests are used to diagnose dysdiadochokinesia?
The accuracy of point-to-point contact, as well as speed, rhythm, and smoothness will be assessed. Lower extremity testing is also often used to diagnose dysdiadochokinesia. For instance, sitting on a chair, the patient is instructed to touch the heel to the knee and then slide the heel up and down the lower leg.

Is dysdiadochokinesia caused by multiple sclerosis or hypotonia?
It could also be a combination of both. What scientists know is that some people with multiple sclerosis and dysdiadochokinesia have an inability to switch certain muscle groups on and off in a coordinated way due to hypotonia, which means decreased muscle tone.
What are the physical symptoms of DDK?
However, someone with DDK will find that their muscle response is slow or awkward, especially in the upper and lower limbs. This can include poor coordination while rapidly tapping one’s finger or foot, opening and closing one’s fist, and switching muscular positions from flexion (bent) to extension (straight).
