Editor’s Note: Volume Overview
With the advent of increasingly accessible Internet-based technologies, it is not difficult to envision a future wherein the practice of telerehabilitation is the norm, rather than an innovative exception. 
This issue of the International Journal of Telerehabilitation (IJT) focuses on three powerful delivery systems: Voice over the Internet Protocol (VoIP); YouTube; and e-mail.
Clinicians are increasingly employing Voice over the Internet Protocol (VoIP) systems such as Skype, Adobe ConnectNow, and ooVoo to conduct telepractice sessions. This is not surprising, as VoIP systems can offer inexpensive and easy ways to deliver telerehabilitation (TR) services. But how might a telerehabilitation clinician determine if their VoIP system is truly secure and private? Valerie Watzlaf, a Registered Health Information Administrator (RHIA), and colleagues Sohrab Moeini and Patti Firouzan address this question. They present HIPAA-based criteria for both therapists and healthcare facilities to consider, and conclude that “therapists must weigh the risks and benefits when deciding to use VoIP software for TR.”
Another excellent contribution to this issue concerns the application of “new media.” M. Hunter Manasco, Nicholas Barone, and Amanda Brown describe the potential role of YouTube in telerehabilitation. Their innovative efforts suggest possibilities that therapists from all rehabilitation disciplines might consider.
Min Jung Kim, Julie A.G. Stierwalt, and Leonard L. LaPointe consider the use of email intervention following traumatic brain injury. These authors’ insightful and detailed review of the literature, and elegant, evidence-based case reports are not to be missed!
And finally, IJT is honored to publish a White Paper that was generated by the American Telemedicine Association’s Telerehabilitation Special Interest Group: “A Blueprint for Telerehabilitation Guidelines.”  
Call for Submissions
The next volume of the International Journal of Telerehabilitation will be published in spring, 2011.
