Abstract

Purpose

This study aimed to assess the following in individuals after stroke: (1) relationship between upper limb (UL) use by direct observation at home with use perceived and measured by accelerometers; (2) complementarity of these three measurements; and (3) relationship between UL bilateral capacity and bilateral use.

Materials and methods

Thirty-one individuals with chronic hemiparesis participated in this cross-sectional study. UL use was assessed using a behavioral map (BM), the Motor Activity Log-Amount of Use (MAL-AOU), and accelerometers, while UL capacity was assessed using the Test d'Evaluation des Membres Supérieurs des Personnes Âgées (TEMPA).

Results

The BM was strongly correlated with perceived use (MAL-AOU, ρ = 0.76) and accelerometer (ρ = 0.70). Bilateral UL use (BM) was moderately (ρ = 0.65) correlated with bilateral MAL-AOU and bilateral use by accelerometers (ρ = 0.62). The BM aided our understanding of how the paretic UL was used. The correlation between bilateral capacity (TEMPA bilateral) and bilateral use (BM) was significant (ρ = 0.49), while that with bilateral MAL-AOU and accelerometer were ρ = 0.68 and ρ = 0.50, respectively.

Conclusion

A BM is a valid way to quantify UL use and can complement information assessed regarding perceived use and by accelerometers.

    Implications for rehabilitation

  • Behavioral maps may be valuable to complement information assessed by perceived UL use and accelerometers.

  • Quantifying bilateral capacity will reflect in a better understanding of actual paretic UL use after stroke.

  • Accelerometers can underestimate the amount of paretic UL use in asymmetrical bilateral tasks.
