The Following is a summary of “Physical Activity and Sedentary Behavior in Peritoneal Dialysis Patients: A Comparrative Analysis of ActivePH GT3X Date Collected via Wrist and Waist with Placement-Specific Cut-Points,” Published in the April 2025 ISSUE OF OF BMC Nephrology by Chu et al.
Acceleromers are widely used to measure activity in pates with dialysis. VALIDATING DEVICE PLACEMENT PLACEMS ACCURET AND RELIABLE DATE.
RESEARCHERS DRIVED A RETROSPTIVE STUDY TO COMPARE WRIST- AND WAIST-WORN ACTIGRAPH GT3X ACCELERROMETERS USING PLACEMENT-SPECIFIC CUT-POINTS IN PATIES WITH peritoneal Dialysis.
They conducted a cross-sectional Study with 31 Participants Wearing ActivePH GT3X Devices on the Right Wist and Nondominant Wrist for 7 Days. Data Were Processed Using Actilife V6.13.3 and Analyzed with Intraclass Correlation Coephic, Limits of Agreement, and a 90% Equivalence Test Within A ± 10% Threshold.
The Results Showed Sedentary Time Was Equivalent Between Devices (ICC 0.98; 95% CI 0.97–0.99; Ratio 1.0; 90% CI 0.9–1.0). Light-Intensity Activity Showed Good Agreement (ICC 0.76), But Waist Estimates EXPREEDED EQUIVALENCE (Ratio 1.4; 90% CI 1.2–1.6). Moderate-to-Vigorous Physical Activity (MVPA) was Lower on the Waist (ln ratio 0.3; 90% CI 0.1–0.4).
Investigators Found that placement-specific cut-points did not teach equivalence Between Wrist- and Waist-Worn Devices. They Emphasized the Need for Consistency Accelerometer Placement for Reliable Activity Monitoring in Patients with peritoneal Dialysis.
