Implication

May warrant cautious clinical use of load sensors; leaves open device-specific validation needs at higher loads.

Structured PICO

Do commercially available load sensors provide valid and reliable clinical strength assessments compared to a gold standard?

I
Intervention
Two commercially available load sensors (including Activ5)
C
Comparator
Gold standard
O
Outcome
Test-retest reliability and agreement with gold standardsurrogate

Commercially available load sensors demonstrate excellent test-retest reliability for clinical strength assessment, though devices like Activ5 may have poorer agreement with gold standard measurements at higher loads.
