“…Technological advancements have led to the development of devices which could improve the monitoring and instruction of weight-bearing. Sensor insoles within shoes are particularly promising because they can measure load and provide biofeedback in "real-time" during dynamic activities (17). Poor PWB adherence following traditional training risks optimal recovery and behoves the study of alternatives.…”

Background Adherence to partial weight-bearing prescription is poor, especially amongst older adults taught with traditional methods. Reasons for this remain unclear and improvements to the instruction of partial weight-bearing are necessary. This randomised controlled trial aimed to investigate how the use of audio-biofeedback during the instruction of partial weight-bearing affected adherence to a weight-bearing limit of 20 kg, compared to the scale method, in older adults. Methods The primary outcome measure was the amount of loading of the partial weight-bearing leg during functional mobility activities, measured as the ground reaction force in Newtons and converted to kilograms. Included were healthy volunteers 60 years of age or older without gait impairment. Participants were randomised into two groups. Blinding was not possible. Partial weight-bearing of 20 kg using crutches was trained with audio-biofeedback (intervention group) or a bathroom scale (control group). The degree of weight-bearing was measured during functional mobility activities (standing, sit-stand-sit, step-up/down and walking) with OpenGo sensor insoles (Moticon ReGo AG, Munich, Germany). A mean load between 15-25 kg was defined as adherent. Weight, height, cognitive function and grip strength were measured. Linear regression analyses were performed to identify factors influencing adherence. Results Thirty volunteers (16 females, 71±6 years, weight 74±17 kg; height 169±9 cm) participated in the trial, fifteen participants in each group. There were no drop-outs. There was no statistically significant difference in weight-bearing between both groups for the activities measured. For the sit-stand-sit activity, weight-bearing for the audio-biofeedback group (21.7±16.6 kg) and the control group (22.6±13 kg) were within the target range. For standing, loading was below the lower threshold (10±7 vs. 10±10 kg). Weight-bearing was above the upper threshold for both groups for: walking (26±11 vs. 34±16), step-up (29±18 vs. 34±20 kg) and step-down (28±15 vs. 35±19 kg). Lower cognitive function, older age, and higher body mass index were associated with poorer adherence to partial weight-bearing. There were no incidents or harms during the trial. Conclusion Audio-biofeedback delivered no statistically significant benefit over the scale method. Lower cognitive function, older age and higher BMI were associated with poorer adherence to partial weight-bearing instructions. Trial registration Not applicable due to the cross-sectional design (one measurement point, no intervention).

Purpose To investigate how audio-biofeedback during the instruction of partial weight-bearing affected adherence, compared to traditional methods, in older adults; and to investigate the influence of individual characteristics. Methods The primary outcome measure of this randomised controlled trial was the amount of load, measured as the ground reaction force, on the partial weight-bearing leg. The secondary outcome was the influence of individual characteristics on the amount of load. Included were healthy volunteers 60 years of age or older without gait impairment. Participants were randomly allocated to one of two groups; blinding was not possible. Partial weight-bearing of 20 kg was trained using crutches with audio-biofeedback (intervention group) or a bathroom scale (control group). The degree of weight-bearing was measured during six activities with sensor insoles. A mean load between 15 and 25 kg was defined as adherent. Results There was no statistically significant difference in weight-bearing between the groups for all activities measured. For the sit-stand-sit activity, weight-bearing was within the adherence range of 15–25 kg (audio-biofeedback: 21.7 ± 16.6 kg; scale: 22.6 ± 13 kg). For standing, loading was below the lower threshold (10 ± 7 vs. 10 ± 10 kg). Weight-bearing was above the upper threshold for both groups for: walking (26 ± 11 vs. 34 ± 16), step-up (29 ± 18 vs. 34 ± 20 kg) and step-down (28 ± 15 vs. 35 ± 19 kg). Lower level of cognitive function, older age, and higher body mass index were correlated with overloading. Conclusion Audio-biofeedback delivered no statistically significant benefit over the scale method. Lower cognitive function, older age and higher body mass index were associated with overloading. Trial registration Not applicable due not being a clinical trial and due to the cross-sectional design (one measurement point, no health intervention, no change in health of a person).
