Reliably determine if the TR process is appropriate and safe for a specific individual? 2. Reliably provide accurate decisions regarding the need for a wheelchair, at a detailed level? 3. Reliably obtain accurate assessments of medical history and physical examination?,Efficacy of Wheelchair System Prescription Using POTS TeleRehab,Assessment/EvaluationInterview- with the Model Patient consists of access to information from a standard information sheet; and an interactive session determining mobility goals, appropriateness of these goals, diagnosis, any changes in condition. Mat evaluation- a physical motor and measurement evaluation either carried out by the Clinician in the face-to-face situation or under the guidance of the Clinician by the Assistant via TR. The purpose of the mat evaluation is to establish passive and active ROM, of the upper and lower extremities, any pathological movement patterns, sitting and transfer skills, spinal orientation, and functional abilities related to mobility and other goals. Measurement- the Clinician or Assistant record linear and angular measurements as required by the data collection form and setting.,Efficacy of Wheelchair System Prescription Using POTS TeleRehab,20 subjects acting as “model patients”4 evaluations/subject Crossover study2 Locations2 In Person (IP)2 TeleRehab (TR)Detailed Protocol Data Collection (Forms)4 Clinicians (2 OT, 2 PT)9 “Assistants” TrainedTeleRehab evaluationTransferROMDimensions,2 Locations,2 Locations,VA Medical Center- Highland DrivePittsburgh,UPMCCenter for Assistive TechnologyPittsburgh,Experimental Schematic,CAT TR,CAT IP,VA IP,VA TR,Clinician 1 evaluation,Clinician 2 evaluation,Clinician 3 evaluation,Clinician 4 evaluation,DAY 1,DAY 2,3-7 DAY DELAYBETWEEN SESSIONS,Efficacy of Wheelchair System Prescription Using POTS TeleRehab,Data Collection: - A team consisting of a Physiatrist; Statistician, 2 OTs; 2 PTs and a Rehabilitation Engineer have developed comprehensive data collection forms to record information on the characteristics of the Model Patient their environment; and the details of the prescription. The forms were derived over a series of iterations and reviews from a collection of existing in house forms and the work of the Assistive Technology Program in Tucson .,Data Collection- Form 1,Data Collection- Form 2,Data Collection- Form 3,Data Collection- Form 3,Data Collection- Form 4,Preliminary Estimations (9 of 20 subjects),Qu. 1.
