Goals/Objectives:
- Extend mobility assessment beyond the clinical setting
- Create new measures to assess fall risk in mobility aid users
- Augment current clinical practice by providing objective measures of mobility characterization
Outline:
Much of the state of the art in mobility assessment that Physical Therapists (PT) use to provide therapy for their patients is based on observational measures. Although many of these assessments (e.g., Functional Gait Assessment, or FGA) are evidence-based and demonstrate strong inter- and intrarater reliability, they are characterized by low resolution and are subject to human error. Such instruments may be easily augmented by an instrumented electronic system to provide objective quantitative data that can be used by PTs to design better therapy plans for their patients. For over 200,000 PTs practicing in the US, such an instrumented tool could be an invaluable asset in the clinic. Moreover, people with mobility impairments (+8.5 million in the US) may themselves benefit from using an instrumented tool at home because it has the ability to produce long-term data logs, which could then be conveniently analyzed by PTs interested in monitoring at-home compliance and progress.
At present, the IntelliCane is being tested with a patient population in collaboration with our partners at Vanderbilt Medical Center’s Pi Beta Phi Rehabilitation Institute. Patients of Pi Beta Phi use the IntelliCane during therapy sessions, producing a large amount of sensor data from real-world evaluations. This information is then analyzed by our researchers to create predictive models of user activity and functional mobility, as well as to provide important objective metrics to PTs regarding their patients’ performance. Future development of the IntelliCane will consist of refinement of the software and algorithm design with a focus on privacy, security, scalability, and user-interface.
