Study name	Effects of transcutaneous electrical nerve stimulation on acute postoperative pain intensity, ambulation and mobility after hip fracture: a double‐blinded, randomised trial
Methods	Randomised trial. Double‐blinded
Participants	People aged over 50 years of age, with stable extracapsular proximal hip fraction (intertrochanteric or subtrochanteric); partial or full weight bearing instructions; ability to ambulate independently for at least 10 m with or without an assistive device prior to the fracture; ability to follow instructions; Mini Mental State Examination test score = 20 Aim: 80 participants
Interventions	1. Active transcutaneous electrical nerve stimulation (TENS) with a biphasic symmetric waveform at a continuous frequency of 100 Hz and phase duration of 200 µseconds 2. Sham TENS
Outcomes	Follow‐up: 5 days Pain level at rest, at night and during ambulation Ambulation status measures Physical performance tests
Starting date	Start date: December 2014 Estimated completion date: December 2015
