About this app

This is a tool to measure your hand stability

Speedometers measure speed. Thermometers measure temperature. But is there anything that measures hand tremor? Now it is! We present you Steady Hands! App measures the stability of your hands by objective scientific methods and modern artificial intelligence algorithms.

App is useful for well-being purposes:

• For individuals with Parkinson's disease or Essential tremor, knowing your
hand tremor level can help you better understand and manage your
symptoms. Also you can track your Vilim Ball tremor reduction journey.#Vilimball

• For seniors, knowing your hand stability level can be a helpful indicator of
overall health and wellness.

• For anyone aiming to maintain or improve hand dexterity, tracking
your hand stability can be a useful way to monitor your progress and
identify areas for improvement.

App is also useful for performance purposes:

• For surgeons, knowing your hand stability level can be an important factor
in ensuring the success of your procedures. Surgeons with a higher level of
hand stability may be able to perform delicate operations with greater
precision and control.

• For archers, stable hands are crucial for accurately hitting your
target. Knowing your hand stability level can help you identify areas for
improvement and enhance your accuracy and precision.

• In both cases, being able to track and monitor your hand stability over
time can help you identify any changes or improvements and make
adjustments to your technique as needed.

Results are visualized in a graph of six columns, each evaluated in the range from 0 (worse) to 10 (perfect).

Measurement methods:

1. Drawing
Drawing is based on a popular Archimedes spiral drawing method that clinicians use to evaluate the severity of patients with neurological conditions. The user‘s task is to trace the spiral with an index finger as closely to the reference as possible. A wobbly line means a stronger tremor, while a smoother line suggests a milder one. Interestingly, the shape of the wobbles gives insights into how similar your tremor is to Parkinson’s disease or the Essential tremor.

2. Picture
The picture approach is analogous to the „Drawing“. However, instead of drawing figures on the screen, you can draw it on a sheet of paper. For a lot of people using a pen feels more natural; therefore, it may be a more suitable solution. The user has to align the phone‘s camera to the drawing and simply press the „photo“ button.
The approach involves complex artificial intelligence algorithms and may be on of our most advanced functions. However, it is still not perfect. To make the most of it you have to make sure that the photo does not contain any unnecessary details, such as palms, paper edges or table textures.

3. Glass
Glass measurement is meant to analyze your postural tremor. This is a type of tremor that occurs when you hold a position against gravity. For example, outstretching the arm in front of you. Interestingly, the tremor severity may be different in a postural position compared to the action position that is encouraged by figure drawing.
This approach asks the user to hold the outstretched arm while holding the phone for 30 seconds. The app uses on-the-phone movement sensors, such as accelerometers, to track the movement and generate the results of the analysis.

4. Tapping
Tapping is a tremor and rigidity measurement approach that is still new in the field. The user is asked to tap randomly appearing points on the screen as fast as possible. The app then analyses various features, such as tapping speed or accuracy to deliver the analysis.

This is not a medical device and is not intended to perform any operations on medically relevant physiological parameters. Every human contains some kind of health tremor, e.g. physiological tremor, a.k.a. hand shakiness, trembling.

The tapping test has disappeared from my app and I miss it! I use the app for quick comparisons when I'm in a DBS programming session. The tapping is useful to gauge how much I have to concentrate to initiate each touch. When we have the programming in a good place I can tap away with little hesitation. Of course, the drawing is especially helpful to do over and over as we try different settings.

Thank you for the kind words, Susan! We promise that the tapping will come back soon. We've temporarily taken it down to enhance its precision and overall performance.

Nice idea, needs better implementation. Lacks instructions. Tests are interesting, but the very detailed results aren't explained. What do numbers mean? What's the purpose of the round checked box? The drawing test lacks an indicator for whether testing left or right hand, which can be done with other tests. (Some people are ambidextrous.) I finally found the history, but it's only for one summary number, not details like frequency or amplitude. Good app, but needs more explanation.

Hi George! Thank you for your feedback! We just released an improved app version. It contains many new functions we believe you'll find valuable.

This rating is kind, as I have only been able to make it work once. It was a good app that one time, though a description of each stat and maybe norms would be helpful to the average user's understanding. It says I have denied the app permissions (I have not), and that the app cannot be used without permission. Force stopped, uninstalled, reinstalled, restarted phone, disabled and re-allowed permissions, etc. No change. I was assessing it for use with my patients, but I need something reliable.

Hi, Michelle, We are sorry for the issues. Good news is that everything is fixed and ready for use. If you'll decide to review the app again, do not hesitate to give us feedback. It's very valuable for us. Especially when it comes from professional. Take a note that the "Drawing" is fully tested tool. Glass and Tapping are still in development.
