CNS Tap Test is an adaptation of the Finger Tap Test (FTT) or Finger Oscillation Test (FOT) which is used to measure the status of the central nervous system (CNS), and is one of the most commonly used tests in neuropsychology, because of its simplicity and reliability, and because it generates relevant data about fine motor control, which is based on motor speed as well as kinesthetic and visual-motor ability.

The application should be used on a regular basis to determine an athlete’s baseline. If the CNS Tap Test result is elevated it is suitable for a maximum effort or a heavy lifting day. If the CNS Tap Test result is lower than average it may indicate CNS fatigue and impending sickness, injury or over-training.

Both hands should be tested on a regular basis in a consistent environment, typically every morning on waking. The procedure for testing is:

- Rest hand palm down on the heel of the hand on a flat surface
- Tapping is done with the index (pointing finger), and all other fingers remain on the flat surface
- The timer starts with the first tap
- When the timer expires no further taps will be accepted
- The result can either be saved or discarded.

Multiple samples can be saved per day.

The resulting data can be graphed, emailed or managed from within CNS Tap Test.

Using Swift Charts for improved accessibility and legibility.

Easy. Fun.

Great app. Simple and direct to use. One suggestion; would be nice to set parameters on graph to eliminate scores saved in error or results belie a threshold that are obviously unwanted to keep results graph cleaner.

Developer Response ,

You can delete scores saved in error by going to Settings (i) | Manage Data and then swipe an individual sample to the left, and it will delete the sample.

Just what I was looking for

CNS testing is an important aspect of weight training. The app is simple, yet effective. It tracks your CNS using the finger tap test. The numbers only mean something as trends. The app gets that.

Now, with the bi-weekly view, I can see the trends in a way that makes sense for my programming.

The only critique I have is that the little 'I' icon isn't the most obvious way to get to your history of results. Doesn't affect its usefulness.

Export Data with Zero import

I purchased this app due to yiutube reviews. But I just switched iphone and I cannot port my data which can be exported by email. This is a poor user experience.

Developer Response ,

The app data is included in iOS backups and will be restored when the phone is restored. The data export is intended for additional analysis not possible in the app.
