Finger tapping test and Parkinson’s

Diagnosis of Parkinson’s can be difficult to confirm by conventional assessments – relying on the judgement of a clinician observing and rating a patient’s movements, or costly brain scans.

It is estimated that clinical mis-diagnosis rates of Parkinson’s may be as high as 25 per cent, even among experienced neurologists. [1][2]


One commonly used dexterity assessment is the ‘finger tapping test’ – where a patient is asked to finger tap for around 10 to 15 seconds for as quickly and widely as they can.

Slowing of speed, loss of amplitude and pauses in finger taps are consistent with ‘bradykinesia’ – a slowness in movement that is one of the most important symptoms in Parkinson’s.

Research has shown that people with Parkinson’s have ‘slower and less rhythmic’ finger tapping movements compared to ‘healthy’ people.

The ClearSky PD-Monitor has been designed to help clinicians during diagnosis and is able to reveal microscopic movements in people with Parkinson’s that are invisible to the naked eye.

Non-invasive electromagnetic tracking sensors are positioned on the index finger and thumb and used to measure a patient’s movements in the finger-tapping test. In real-time, the movement of their fingers is recorded by a computer.

These movements are then analysed using evolutionary algorithms to measure subtle hesitations that are seen in people with Parkinson’s.

My wife was diagnosed of Parkinson’s Disease at age 61. She had severe calf pain, muscle pain, tremors, slurred speech, frequent falls, loss of balance, difficulty in getting up from sitting position. She was put on Senemet for 6 months and then Siferol was introduced and replaced the Senemet. During this time span she was also diagnosed with dementia. She started having hallucinations and lost touch with reality. Last year, our family doctor started her on Uine Health Centre PD-5 formula, 2 months into treatment she improved dramatically. At the end of the full treatment course, the disease is totally under control. No case of dementia, hallucination, weakness, muscle pain or tremors. My wife is strong again and has gone…

My husband was diagnosed of Parkinson’s Disease a couple of years ago, he had severe fatigue, difficulty with mobility and sleeping. He was placed on Sinemet 3 times daily, which helped but only for a short while. So, we decided to try alternative treatment and began on PD-5 protocol, it has made tremendous difference for my husband, he had improved walking balance, muscle strength and he is now very active. His Parkinson’s is totally under control, we got the treatment from binehealthcenter.com. This treatment is a breakthrough for PWP!
