Abstract

OBJECTIVES: To determine whether a home‐based pedometer‐driven walking program with arthritis self‐management education (Walk +) would increase physical activity, muscle strength, and functional performance in older adults with osteoarthritis (OA) of the knee as opposed to arthritis self‐management education alone (EDU). DESIGN: A randomized two‐by‐three (group‐by‐time) design with participants assigned to Walk + (n = 17, mean age ± standard deviation = 69.6 ± 6.7) or EDU (n = 17, age = 70.8 ± 4.7). SETTING: Community located in the Baltimore‐Washington area. PARTICIPANTS: Thirty‐four community‐dwelling adults, aged 60 and older with symptomatic knee OA and self‐reported functional impairment. INTERVENTIONS: Both groups received 12 hours of the Arthritis Self‐Management program over 12 weeks and were followed for an additional 12 weeks. In addition, the Walk + group received individualized instruction in the use of a pedometer, with the goal of increasing their step count by 30% of their baseline step count. MEASUREMENTS: The outcome measures were physical activity (daily step counts and total activity vector magnitude as measured by a pedometer and Tritrac‐R3D accelerometer), quadriceps femoris strength (isometric peak torque), and functional performance tasks (100‐foot walk‐turn‐walk, timed stair climb, timed chair rise, and pain status). RESULTS: Daily steps walked showed a significant group‐by‐time interaction ( P = .04) after controlling for age. From baseline to completion of training, a 23% increase in daily steps occurred in the Walk + group and a 15% decrease in the EDU group. Although steps increased in the Walk + group, total activity vector magnitude was maintained, suggesting a more efficient gait. The Walk + group became quicker than the EDU group in the normal‐pace walk‐turn‐walk ( P = .04). An isometric strength gain of 21% postintervention was seen in the Walk + group, compared with a loss of 3.5% in the EDU group. CONCLUSION: In older adults with symptomatic knee OA, Walk + appears to increase walking, with improvements in muscle strength and walking performance. The use of a home‐based pedometer‐driven program to increase physical activity, strength, and function in this population warrants further research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
