Useful research.
Honest limits.
Technology should support the life your parent wants. We explain what studies found, who they studied, and what remains uncertain.

Choosing technology for independence: what the evidence can and cannot tell you
Four kinds of evidence
- Peer-reviewed research: findings from published studies. Study design, participants, setting, and limitations matter.
- Manufacturer information: model specifications, compatibility, prices, and contract terms. These do not establish health benefits.
- Hands-on observations: only tests we actually perform and document. No hands-on product testing is claimed for this research section.
- Unknown: information we could not verify. We will not replace it with an assumption.
A study of a technology category is not an endorsement of every device in it. Peer review is a useful quality filter, not a guarantee that a finding applies to your parent or a current product.
