- ItemInternet-based outpatient telerehabilitation for patients following total knee arthroplasty: a randomized controlled trial.(2011-01-20) Russell, Trevor G; Buttrum, Peter; Wootton, Richard; Jull, Gwendolen Atotal knee arthroplasty is an effective means for relieving the symptoms associated with degenerative arthritis of the knee Rehabilitation is a necessary adjunct to surgery and is important in regaining optimum function Access to high quality rehabilitation services is not always possible especially for those who live in rural or remote areas The aim of this study was to evaluate the equivalence of an Internet based telerehabilitation program compared with conventional outpatient physical therapy for patients who have had a total knee arthroplasty
- ItemInternet-based physical assessment of people with Parkinson disease is accurate and reliable: a pilot study.(2013-09-09) Russell, Trevor G; Hoffmann, Tammy C; Nelson, Mark; Thompson, Leah; Vincent, AmyTelerehabilitation may be an alternative service delivery model for people with Parkinson disease PD who live in areas where traditional rehabilitation services are not readily accessible The aim of this study was to determine the accuracy and reliability of performing remote physical assessments of people with PD via telerehabilitation when compared with traditional face to face assessments Twelve subjects were simultaneously examined by a face to face investigator and a remote investigator via the eHAB telerehabilitation system The outcome measures evaluated included the timed stance test Timed Up and Go test step test steps in 360 degree turn Berg Balance Scale and lateral and functional reach tests Limits of agreements intervals and weighted kappa statistics demonstrated the telerehabilitation assessments to be accurate within clinically acceptable limits A high level of inter and intrarater reliability was demonstrated across all telerehabilitation assessments This study indicates that it is possible to assess the physical ability of people with PD via telerehabilitation systems and provides support for the further development of telerehabilitation applications for patients with neurological disorders
- ItemAn Internet-based telerehabilitation system for the assessment of motor speech disorders: a pilot study.(2006-03-14) Hill, Anne J; Theodoros, Deborah G; Russell, Trevor G; Cahill, Louise M; Ward, Elizabeth C; Clark, Kathy MThis pilot study explored the feasibility and effectiveness of an Internet based telerehabilitation application for the assessment of motor speech disorders in adults with acquired neurological impairment
- ItemLow-bandwidth telerehabilitation for patients who have undergone total knee replacement: preliminary results.(2004-01-19) Russell, Trevor G; Buttrum, Peter; Wootton, Richard; Jull, Gwendolen AWe have developed a low bandwidth Internet based telerehabilitation system to provide outpatient rehabilitation to patients who have undergone total knee arthroplasty The preliminary efficacy of this treatment programme in terms of both physical and functional objective outcome measures was assessed on 21 patients Subjects receiving a six week rehabilitation programme were randomized to the telerehabilitation system or the usual face to face method The physical and functional improvements in the telerehabilitation group were similar to those in the control group There was a non significant trend for greater improvements in the telerehabilitation group for most outcome measurements The telerehabilitation programme was well received by patients The results of this study provide evidence for the efficacy of low bandwidth telerehabilitation consultations
- ItemPaediatric palliative home care with Internet-based video-phones: lessons learnt.(2004-12-17) Bensink, Mark; Armfield, Nigel; Russell, Trevor G; Irving, Helen; Wootton, RichardWe have designed and tested an Internet based video phone suitable for use in the homes of families in need of paediatric palliative care services The equipment uses an ordinary telephone line and includes a PC Web camera and modem housed in a custom made box In initial field testing six clinical consultations were conducted in a one month trial of the videophone with a family in receipt of palliative care services who were living in the outer suburbs of Brisbane Problems with variability in call quality namely audio and video freezing and audio break up prompted further laboratory testing We completed a programme of over 250 test calls Fixing modem connection parameters to use the V 34 modulation protocol at a set bandwidth of 24 kbit s improved connection stability and the reliability of the video phone In subsequent field testing 47 of 50 calls 94 connected without problems The freezes that did occur were brief with greatly reduced packet loss and had little effect on the ability to communicate unlike the problems arising in the home testing The low bandwidth Internet based video phone we have developed provides a feasible means of doing telemedicine in the home
- ItemPhysical outcome measurements via the Internet: reliability at two Internet speeds.(2003-00-03) Russell, Trevor G; Wootton, Richard; Jull, Gwendolen AWe have developed a software application to enable interactive rehabilitation via the Internet The reliability of the telemedicine application was examined by comparing it with face to face assessment The physical outcome measures assessed were knee range of motion quadriceps muscle strength limb girth and an assessment of gait One therapist performed both in person and Internet based measurements of all outcome measures on 20 normal subjects There was good agreement between the two techniques the 95 limits of agreement included zero for all the variables studied Internet assessments were conducted at two bandwidths ISDN at 128 kbit s and the telephone network at 17 kbit s Bandwidth had no significant influence on any of the measures This study suggests that Internet based physiotherapy interventions delivered to the home are suitable for further development
