The screening Hand Assessment for Infants: Feasibility, validity, and reliability based on parents' recordings.

The study included only 30 infants from one Swedish hospital follow-up programme, so it may not apply to other settings. Reliability was tested on only the first 16 recordings, and two individual items for the non-affected hand had only moderate agreement between raters. The same first author scored both the parent-recorded s-HAI and the six-item clinic HAI, even though the analyses were separated by about 7 to 14 days. Parents needed Swedish or English, a smartphone, and most had college or university education, so the findings may not transfer to families with different language, education, or technology access. Some recordings were approved even though they did not meet every quality criterion, and the reasons for repeated recordings were not documented. The study reports feasibility, validity, and reliability, not treatment outcomes.

The authors declared no conflict of interest. Funding was provided by Stiftelsen Frimurare Barnhuset i Stockholm, Stockholm läns landsting, Knut och Alice Wallenbergs Stiftelse, Linnéa och Josef Carlssons Stiftelse, and Stiftelsen Promobilia.

Do not read the s-HAI as a proven diagnostic or treatment tool. The study showed agreement between parent-recorded and clinic scores, but it did not test whether using the screen improves outcomes for infants at risk of unilateral CP.
