Abstract:
This multi-centred, randomised controlled trial explored the effects of adding ongoing feedback to a 12-month unsupervised maintenance walking program, on daily physical activity (PA) in people with chronic obstructive pulmonary disease. Participants were randomised to either an intervention group (IG) or a usual care group (UCG). During the maintenance program, the IG received ongoing feedback (telephone calls, biofeedback provided via pedometer and progressive goal setting) and the UCG received no feedback. The SenseWear® Pro3 Armband was used to measure PA. Of the 86 participants {IG = 42, (mean [SD]: age 70 [7] years; FEV1 43 [16] % predicted); UCG = 44, (age 69 [9] years; FEV1 44 [15] % predicted)} included at baseline, 43 had sufficient data to be included in the final analysis. There were no between-group differences in any of the PA variables from baseline to completion of the program (all p > 0.05). Ongoing feedback was no more effective than no feedback in improving PA during a 12-month unsupervised walking program.Trial Registration: The trial was registered in the Australia and New Zealand Clinical Trials Registry (ACTRN12609000472279).

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
