Background: This study examined the reliability and accuracy of five talking pedometers: Brookstone Talking Pedometer, Voice Zone, Sportline 343, Accusplit Alliance AL300, and Oregon Scientific PE829. All pedometers announced cumulative step count when the talk button was pressed.

Methods: Ten older adults (73 ± 5.5 years old), and 13 adults with visual impairments (42.4 ± 13.6 years old) wore the pedometers during a 50 step walk, ascending and descending stairs. Pedometer step counts were compared to hand-tally counts.

Results: All pedometers underestimated actual steps with higher prevalence of under-counting when ascending stairs and descending stairs. Average absolute error follow: Brookstone (13.0% ± 13.8), Accusplit (18.7% ± 21.7), Voices Zone (20.2% ± 18.1), Oregon Scientific (25.7% ± 24.3) and Sportline (33.7 ± 25.5).

Conclusions: The Brookstone and Accusplit pedometers were the most accurate models. None of the talking pedometers tested appeared appropriate for research (maximum of 5% error) or general use (maximum of 10% error).
