Enhancing hand function in patients with hematologic malignancies: a novel knitted glove approach.

Only six patients took part, and there was no comparison group. Hands may have stayed the same or improved for reasons that have nothing to do with the glove, and the study cannot tell you either way. Only four of the six had data at two weeks, and the one significant result (on the Box and Block Test) rests on those four. Wear time was reported by the patients themselves, so people may have misremembered how long they wore the glove. The patients were a mixed group: a wide age range, three different blood cancers, and different treatments, including one bone marrow transplant. What worked or did not work for any one of them is hard to separate. Some patients did not improve and some got worse, which the authors say suggests some people respond to the glove and others do not. The assessment period was short: two weeks at most, during a hospital admission. The authors state that the small numbers limit the study's statistical power and that the results may be overestimated.

The study received no specific funding from any public, commercial or not-for-profit source, and the authors state they have no conflicts of interest.

Do not read this as evidence that the glove strengthens hands. Grip strength and pinch strength did not change, and the only significant result was on a block-moving dexterity test, where just two of the six patients improved by the amount the paper calls clinically meaningful. There was no control group, so nothing here shows the glove caused any change.
