Implementation of Partial Load through Instruction with Biofeedback Compared to the Standard Method
Résumé de l'étude
In orthopedics and traumatology, partial loading is a common treatment protocol following a surgical procedure, aimed at stimulating the affected structure (e.g., after an implant) while simultaneously avoiding overloading to prevent re-injury. The instruction regarding the permissible weight on the affected leg prescribed by the doctor is carried out by the physiotherapist. This is usually guided with a personal scale to demonstrate the permissible weight while standing. Implementing these guidelines in daily activities, such as walking or climbing stairs, often poses a significant challenge for patients. Measuring the load and providing direct feedback on the weight to the patient while walking could enhance the guidance and application of the permissible weight load for the patient, thereby improving the clinical outcome. The aim of this study is to determine whether patients after orthopedic surgical procedures adhere better to the prescribed load limits when instructed using a biofeedback method that provides visual and auditory feedback on the load via pressure measurement insoles, compared to patients guided by the standard method using a personal scale. In this randomized controlled study, both methods for guiding partial loading will be examined and compared in a total of 60 patients. Patients will be measured and assessed after an introductory instruction to determine the proportion of steps exceeding the permissible load limit. This measurement will be repeated after a 6-week trial phase.

Intervention étudiée
The intervention group receives instructions on the permissible weight load using a pressure measurement insole placed in the shoe (STAPPONE Rehab, Vienna). The weight load applied to the foot is measured and displayed to the patient both visually and audibly via a smartphone app. The insole is used during daily movements such as walking or climbing stairs. The instruction is provided by a trained physiotherapist and is continuously conducted at home during the first 6 weeks post-surgery. The control group receives instructions for partial loading according to the standard method. The permissible weight is demonstrated to the patient once using a personal scale while standing and is then to be implemented while walking (without the scale). The guidance is also provided by a trained physiotherapist.
