Study name	COMplex Fracture Orthopedic Rehabilitation (COMFORT): real‐time visual biofeedback on weight bearing versus standard training methods in the treatment of proximal femur fractures in elderly: a randomised controlled trial
Methods	Randomised controlled trial; single‐blind
Participants	Age ≥ 60 years; participants rehabilitate from a proximal femur fracture following low‐energy trauma; prescribed unrestricted weight bearing after (surgical) treatment of their fracture; expected clinical rehabilitation duration of ≥ 2 weeks; bodyweight ≤ 120 kg Aim: 186 participants
Interventions	1. Real‐time, visual feedback about weight bearing during 30 m walk 2. Control: active
Outcomes	Primary outcome measures SensiStep parameters maximum peak load (in % bodyweight) Step duration (in seconds) Secondary outcomes Spatio‐temporal gait parameters Elderly Mobility Scale Functional Ambulation Categories Visual Analogue Scale
Starting date	Study start date: March 2017 Completion date: August 2018
