Purpose[edit | edit source]
Sollerman Hand function test is used in the assessment of hand functions. It shows the ability and quality of the hand while performing activities of daily living. The test is highly significant in hand surgery for the assessment of the choice of treatment and results of treatments.
Description[edit | edit source]
Sollerman Hand function test was developed on the notion that the prehensile movements of the human hand can be expressed as variations of basic hand grips.
The main eight hand grips in activities of daily living(ADL) into which a normal grip pattern can be divided are
| Hand Grips | Position | Percentage use in ADL(%) |
|---|---|---|
| Pulp pinch | The object is held between the thumb and the index or the middle finger, or both | 20 |
| Lateral pinch | The object is held between the thumb and the radial side of the index finger | 20 |
| Tripod pinch | The object is surrounded by the thumb, index and middle finger. It may have contact with the web of the thumb | 10 |
| Five-finger pinch | The object is held between the thumb and the four fingers together. It has no contact with the palm | 15 |
| Diagonal volar grip | The object is held with the thumb against the four fingers. It has contact with the palm and its axis is diagonal to that of the hand | 15 |
| Transverse volar grip | The object is held with the thumb against the four fingers. It has contact with the palm and its axis is transverse to that of the hand | 14 |
| Spherical volar grip | The object is surrounded by the thumb and the four fingers and has contact with the palm | 4 |
| Extension grip | The object is held between the thumb and the four fingers, which are extended in the interphalangeal joints. It has no contact with the palm | 2 |
Sollerman Hand function test includes 20 subtests, each involving an ADL task. The performance of each subtest is scored on a scale of 0 to 4 points. The points are graded as follows:
| Score | Performance |
|---|---|
| 0 | The patient could not carry out the task |
| 1 | The task was partially performed within 60 seconds |
| 2 | The task was completed, but with great difficulty, or the task was not carried out with the prescribed hand-grip, or the task was not completed within 40 seconds but within 60 seconds |
| 3 | The task was completed, but with slight difficulty, or the task was carried out with the prescribed hand-grip but with slight divergence from normal, or the task was not completed within 20 seconds but within 40 seconds |
| 4 | The task was carried out without any difficulty within 20 seconds and with the prescribed hand-grip of normal quality |
The grading system takes notes of the time taken to carry out tasks, the level of difficulty and the quality of hand performance. Patients with normal hand function would achieve 80 points with the dominant hand and 77-79 points with the non-dominant hand.
