## What is CNS Tap Test?

As featured in the book Beyond Training by Ben Greenfield.

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.

### 1/5 — Strange interface, needs refinement

*2024-10-09, version 1.5.5*

The app is pretty confusing to navigate and I'm not quite sure where I need to go to do stuff. This app looks very plain and isn't very useful.

### 5/5 — 2015-2024 crew 🫡

*2024-04-27, version 1.5.3*

No nonsense. No imitators. Just a cracking simplistic tap test for checking my athletes CNS/fatigue levels.

### 3/5 — App due a refresh

*2021-01-12, version 1.4.2*

It would be great to see App refresh and the time of day added to the graphs to see best performance?

### 1/5 — Stupid. No benefit

*2019-04-09, version 1.4.0*

This gives you no real information. Ridiculous

### 1/5 — If I could return it I would

*2019-01-30, version 1.4.0*

This app should be free

### 2/5 — Export Data with Zero import

*2018-10-19, version 1.3.0*

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.

### 5/5 — Easy. Fun.

*2018-06-05, version 1.3.0*

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.

### 5/5 — Great monitor

*2017-10-09*

Excellent App to monitor you recovery rate and confirm you are functioning to you capacity.

### 5/5 — Awesome app!

*2017-06-11*

Good way to gauge how you are really feeling body wise! Based on sound physiological principles that allow a simple yet effective biofeedback tool!

### 5/5 — Great app

*2016-12-07, version 1.2.8*

I use this app first thing after I weigh.  The app is a good tool to help give me a bit of insight into how I am feeling with my work out and recovery.

## Frequently asked questions about CNS Tap Test

### What does the CNS Tap Test app do?

The app measures your central nervous system (CNS) status by adapting the Finger Tap Test. It quantifies your fine motor control based on motor speed and visual-motor ability. Regular use helps you understand your body's readiness for training or potential signs of fatigue.

### How does the finger tapping test work?

You rest your hand palm down on a flat surface and tap repeatedly with your index finger for a set timer duration. The app records the number of taps within that time. This data is then used to assess your CNS status.

### What do the test results mean?

An elevated result suggests you are ready for maximum effort or heavy lifting. A lower-than-average result may indicate CNS fatigue, potentially signaling impending sickness, injury, or over-training. It's recommended to test consistently, ideally every morning upon waking.

### Can I track my progress over time?

Yes, the app allows you to save your test results and view them graphically. You can also email or manage this data from within the application. This trending capability helps you monitor changes in your CNS status.

### Is this app compatible with my device?

The application is built using Swift Charts for improved accessibility and legibility, suggesting it is designed for modern iOS devices. Specific compatibility details would typically be found on the app store listing.
