A new “telerehabilitation” approach lets physical therapists assess patients with low back pain (LBP) over the Internet
A new “telerehabilitation” approach lets physical therapists assess patients with low back pain (LBP) over the Internet, with good accuracy compared with face-to-face examinations, reports a study in the May 15 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Taking advantage of Skype and other widely-used services may make telerehabilitation a more feasible alternative to in-person clinic visits, according to the new research by Prof. Manuel Arroyo-Morales and colleagues of University of Granada, Spain. They believe their results “give preliminary support to the implementation of web-based LBP assessment systems using video recordings that can be evaluated by different therapists.”
Can Back Pain Assessments Be Performed Over the Internet?
The researchers designed and evaluated a web-based telerehabilitation system for performing routine clinical assessments of patients with LBP. The telerehabilitation setup operated across a low-bandwidth Internet connection between two personal computers equipped with webcams.
The system included the popular Skype videoconferencing service, allowing the patient and physical therapist could see and talk to each other in real time. The therapist guided the patient in performing specific movements, and captured video clips for analysis using video motion analysis software (Kinovea). The therapist and patient were also able to complete standard back pain questionnaires using the web-based system.
Fifteen patients with chronic LBP underwent two assessments in random order: once face-to-face and once using the telerehabilitation setup. Accuracy was assessed by comparing the results of telerehabilitation assessment with those of in-person assessment.
The results showed good agreement between the two evaluations, supporting the use of telerehabilitation for clinical assessment of LBP. There was good correlation for measures made on video motion analysis, such as spine mobility and back muscle endurance; as well as questionnaire-based assessments such as disability, pain, and health-related quality of life.
Skype and Other Tools Make Telerehabilitation More Feasible
The telerehabilitation setup showed consistent results for the same therapist at different times (intra-rater reliability) as well as for assessment by independent therapists (inter-rater reliability).
