What this helps track
Tremor and hand control assessments use guided drawing, tracing, and steadiness tasks to help track hand stability and fine motor control over time.

Guided tasks for tremor, steadiness, and fine motor control.
Why it matters
Tremor can change subtly week to week. A consistent, guided assessment makes it easier to notice trends in steadiness, postural tremor, and fine motor control.
What this assessment measures
Tremor and hand-control tasks measure fine motor steadiness, postural stability, and drawing precision — the observable movement signals clinicians commonly consider when evaluating tremor severity and progression. Because tremor amplitude fluctuates with caffeine, sleep, stress, and medication timing, a single measurement rarely tells the full story. Repeating the same guided tasks builds a longitudinal picture that is less sensitive to any one day.
How it works
What a typical session looks like
Each session is short and guided end-to-end, so you can focus on the task.
- 1Rest your arm and device on a stable surface before beginning.
- 2Follow on-screen prompts to draw a spiral and trace lines with your dominant hand.
- 3Complete a short postural-hold task so steadiness can be sampled.
- 4Optionally note recent medication timing, sleep, and stress to add context.
- 5Repeat with the same setup so sessions stay comparable.
What your results show
You'll see steadiness scores for each task and how they compare with your recent range. Reviewers commonly look at trends across weeks, correlating steadier or shakier windows with medication timing, sleep, or stress notes captured during the session.

Common questions
Frequently asked questions
Quick answers about the tremor and hand control assessment on Alumina Health.
Does Alumina diagnose essential tremor or Parkinson's disease?
No. Alumina Health is a tracking tool, not a diagnostic device. Diagnosing tremor requires a clinical evaluation. The app helps you record steadiness and drawing precision over time so trends are easier to discuss with a clinician.
Does it matter which hand I use?
Use the same hand each time you repeat a task. Many people track their dominant hand; if tremor differs between sides, consider running the sequence on both.
How is tremor steadiness scored?
The app analyzes touch-path deviation on drawing and tracing tasks. Rather than a diagnostic threshold, the score is best read against your own baseline over multiple sessions.
Should I complete a session before or after medication?
Both can be informative. Many people log a session at a consistent time relative to their medication schedule so on and off windows can be compared over time.
Can caffeine or fatigue affect my results?
Yes. Caffeine, fatigue, stress, and cold hands are all known to increase tremor amplitude. Noting these factors in the session helps put a shakier day in context.
