The Jebsen Taylor Hand Function Test, often abbreviated as JTHFT, is a reliable and widely-used clinical assessment tool designed to evaluate hand function and dexterity. This test, developed by Dr. Jebsen and Dr. Taylor, consists of seven subtests that mimic common daily activities, providing a comprehensive evaluation of hand function. This article serves as an instruction manual, guiding you through the administration, scoring, and interpretation of the Jebsen Taylor Hand Function Test.
Understanding the Jebsen Taylor Hand Function Test
The JTHFT is a norm-referenced, standardized test that measures the time required to complete each of the seven subtests. It is suitable for individuals aged 6 to 85 years and is commonly used in clinical settings, research, and rehabilitation programs. The test is designed to assess fine motor skills, dexterity, and functional hand use.
Test Materials and Administration
To administer the JTHFT, you will need the following materials:

- Jebsen Taylor Hand Function Test Kit (including all seven subtest items)
- Stopwatch or timer
- Scoring sheet
- Pencil
The test kit includes the following subtest items:
- Writing (pencil and paper)
- Turning cards (deck of cards)
- Picking up small objects (beans)
- Assembly (small nuts and bolts)
- Simulated feeding (spoon and small objects)
- Stacking checkers (checkers and checkerboard)
- Lifting large objects (weighted cans)
Administering the Jebsen Taylor Hand Function Test
Preparation
Before administering the test, ensure that the examinee is comfortable and understands the task requirements. Demonstrate each subtest using the dominant hand, then have the examinee practice the task with their dominant hand. If the examinee has an upper extremity impairment, test the affected side first.
Administering Each Subtest
For each subtest, provide clear instructions and ensure the examinee understands the task. Start the timer as the examinee begins the task and stop it when they have completed the task. Record the time taken for each subtest on the scoring sheet.

Scoring the Jebsen Taylor Hand Function Test
Scoring the JTHFT involves converting the time taken for each subtest into a scaled score, which can be compared to normative data. The test manual provides tables for converting raw scores to scaled scores for each age group. To calculate the total scaled score, sum the scaled scores from each subtest.
| Subtest | Raw Score (Time in seconds) | Scaled Score |
|---|---|---|
| Writing | ... | ... |
| Turning cards | ... | ... |
| Picking up small objects | ... | ... |
| Assembly | ... | ... |
| Simulated feeding | ... | ... |
| Stacking checkers | ... | ... |
| Lifting large objects | ... | ... |
| Total Scaled Score | ... | ... |
Interpreting the Jebsen Taylor Hand Function Test Results
Interpretation of the JTHFT results involves comparing the total scaled score to normative data. The test manual provides percentiles, means, and standard deviations for each age group. A higher total scaled score indicates better hand function. Additionally, you can analyze the performance on individual subtests to identify specific areas of strength or weakness in hand function.
It's essential to consider the examinee's age, gender, and any relevant medical history when interpreting the results. The JTHFT can be used to monitor progress in rehabilitation programs, compare hand function between groups, or make decisions about intervention strategies.
