Grip Force in Patients with Rheumatoid Arthritis and Fibromyalgia and in Healthy Subjects. A Study with the Grippit Instrument
Abstract
Nordenskiöld UM, Grimby G. Grip Force in Patients with Rheumatoid Arthritis and Fibromyalgia and in Healthy Subjects. A Study with the Grippit Instrument. Scand J Rheumatol 1993; 22: 14–19.The reliability of the grip force instrument, Grippit was tested on 51 right-handed women of which 18 were healthy, 19 had rheumatoid arthritis (RA) and 14 had fibromyalgia (FM). Normative data was obtained from 169 healthy subjects. Results indicate that the reliability of Grippit was high in healthy and rheumatoid arthritic women and satisfactory in women with fibromyalgia. All patients showed greatly reduced grip force (RA had on average 21% and FM 40% of the control values) when compared to healthy women. Healthy women had on average 54% of men's grip force. The ratio between average force over 10 seconds and peak force was 73% for RA women, 69% for FM women, 83% for healthy women and 85% for healthy men.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
