Capturing hand use of individuals with spinal cord injury at home using egocentric video: a feasibility study.

Study Design: Feasibility study.

Objective: The objective of this study is to explore the feasibility of capturing egocentric (first person) video recordings in the home of individuals with cervical spinal cord injury (SCI) for hand function evaluation.

Setting: Community-based study in Toronto, Ontario, Canada.

An Effective and Efficient Method for Detecting Hands in Egocentric Videos for Rehabilitation Applications.

Individuals with spinal cord injury (SCI) report upper limb function as their top recovery priority. To accurately represent the true impact of new interventions on patient function, evaluation should occur in a natural setting. Wearable cameras can be used to monitor hand function at home, using computer vision to automatically analyze the resulting egocentric videos.

Egocentric video: a new tool for capturing hand use of individuals with spinal cord injury at home.

Background: Current upper extremity outcome measures for persons with cervical spinal cord injury (cSCI) lack the ability to directly collect quantitative information in home and community environments. A wearable first-person (egocentric) camera system is presented that aims to monitor functional hand use outside of clinical settings.

Methods: The system is based on computer vision algorithms that detect the hand, segment the hand outline, distinguish the user's left or right hand, and detect functional interactions of the hand with objects during activities of daily living.
