Objective[edit | edit source]
The FIHOA is a measure to assess hand function in people with hand osteoarthritis (OA). It is a 10-item questionnaire developed by Dreiser et a.l in 1995[1][2]. It has been translated into French, Dutch, and Argentinian versions. It is targeted at the functional capacity of hands in OA-affected patients[1]. It is also called Dreiser's index.
Intended Population[edit | edit source]
The targeted population is Osteoarthritis patients, but it can also be used in Rheumatoid arthritis, in patients whose hand function needs to be assessed.
Method of Use[edit | edit source]
Equipment Required:
None. Questionnaire-based.
Time to administer:
5-10 mins.
Training Required:
None.
Method of Administration:
Physician/physiotherapist administered, self-reported
Instrument[edit | edit source]
It contains 10 questions with a score range of 0–30[1].
| Sr. no. | Question asked | Scoring | |||
|---|---|---|---|---|---|
| 0 | 1 | 2 | 3 | ||
| 1 | Are you able to turn a key in a lock? | ||||
| 2 | Are you able to cut meat with a knife? | ||||
| 3 | Are you able to cut cloth or paper with a pair of scissors? | ||||
| 4 | Are you able to lift a full bottle with the hand? | ||||
| 5 | Are you able to clench your fist? | ||||
| 6 | Are you able to tie a knot? | ||||
| 7 | For women: Are you able to sew? For men: Are you able to use a screwdriver? | ||||
| 8 | Are you able to fasten buttons? 9. 10. | ||||
| 9 | Are you able to write for a long period of time? | ||||
| 10 | Would you accept a handshake without reluctance? | ||||
0=possible without difficulty, 1=possible with slight difficulty, 2=possible with important difficulty, 3=impossible.
Total scores indicate hand function. Lower the scores, better the hand function[1].
Psychometric Properties[edit | edit source]
Reliability:
- Interrater: in OA, Cronbach's alpha is 0.90[3][4]. In RA, Cronbach’s alpha test: 0.94[5]
- Test-Retest: by administering the FIHOA two times 1 week apart gave an ICC of 0.74 and two times with a 5-day interval yielded an ICC of 0.96 in OA[3][4]
- Intra-rater: by testing patients with OA two times, 1 hour apart. The correlations between the scores were 0.95[3][4]
Validity:
For OA, FIHOA correlated with[4]
- the Cochin Hand Function Scale (rs = 0.89) and
- Michigan Hand Outcomes Questionnaire (rs = 0.86),
- total Australian Canadian Osteoarthritis Hand Index (rs = 0.76)
Thus, it was found reliable and valid for OA.
For RA, FIHOA was found to be reliable, valid, and reproducible[5].
