Spatial exploration strategy training for spatial neglect: A pilot study.

A pilot with only 40 people analysed and a single session of about 20 to 30 minutes, so it says nothing about how many sessions are needed or whether any change lasts. Nothing was measured outside the object search task: no test of whether patients carried the strategies into daily activities, and the paper says that is still to be studied. The treatment group was already doing worse than the control group before the session on both outcome measures, so some of the apparent benefit is the control group declining rather than the treatment group improving. Groups were decided by the last digit of the medical record number, not by a proper random draw, and the paper reports that the treatment group was younger and had more men. Patients had a wide range of neglect severity, and those with mild neglect may have scored at the top of the tests before the session, leaving no room to show change. Three recruited patients did not meet all the entry criteria and one could not complete testing, so 4 of the 44 recruited were not analysed. Several results, including the page-by-page changes during the session, come from analyses done after the fact rather than from the pre-stated hypotheses, and the sample was too small to test the effect of the changing task conditions.

The authors state that they have no conflict of interest to declare. The text provided does not name a funder.

Do not take this as proof that guided strategy training works for spatial neglect. The number of objects patients found did not change after one session; only how evenly they searched did, and the control group was performing better than the treatment group before the session and then got worse. One short session in 40 people cannot show a treatment works.
