Prism Adaptation Treatment for Right-Sided and Left-Sided Spatial Neglect: A Retrospective Case-Matched Study.

The study was retrospective, meaning patients were not randomly assigned to treatment groups, and other concurrent therapies or interventions were not controlled for. The fidelity of how Prism Adaptation Treatment was delivered by different clinicians was unknown. Outcome measures like the FIM are broad; improvements in specific communication or motor skills could have influenced scores independently of neglect reduction. The study lacked long-term follow-up data after discharge, so it is unclear if the benefits persisted. Neuroimaging data was not available, so the specific location of brain lesions could not be correlated with treatment response.

The study was performed at Kessler Foundation, and the authors note that the same dataset was used in previous published analyses. No specific funding sources or conflicts of interest are explicitly detailed in the provided text beyond the institutional affiliation.

Do not conclude that Prism Adaptation Treatment is superior for right-sided neglect based on the KF-NAP results alone. The study found no difference in functional independence or discharge outcomes between the two groups, suggesting that the greater reduction in neglect severity scores did not translate into better overall functional recovery.
