Validity and reliability of a smartphone inclinometer app for measuring passive upper limb range of motion in a stroke population*

Abstract

Purpose: To demonstrate the validity and reliability of a smartphone app to measure ROM after stroke. Materials and methods: Twenty-one stroke survivors with a diagnosis of stroke that affected the motor cortex or subcortical motor pathways and were hospital inpatients at one of two metropolitan hospitals were recruited. A within-session test-retest design was used to compare ROM measurements taken using the GetMyROM app for iPhone to those taken by a digital inclinometer. Torque-controlled passive elbow and wrist extension were collected and statistical analysis of concurrent validity and test-retest reliability performed. Results: GetMyROM app was valid when compared to the digital inclino..
