Classification of Paraplegia
Sub-Maximal Tests Performed Independently
Classification of wheelchair users for the application is based on a scale from 1 – 4.5 in 0.5 increments
Application incorporates classification scores according to the International Wheelchair Basketball Federation Manual2
Class 1: T1-T7 paraplegia
Class 2: T8-L1 paraplegia
Class 3: L2-L4 paraplegia
Class 4: Single or double below-knee amputees
Fitness assessments provide clinicians with reliable and valid data concerning patient state
Maximal testing requires maximal effort, proving difficult in individuals with disabilities
Sub-maximal testing is less labor intensive and requires less monitoring equipment to conduct
Mobile application technology has emerged as a valuable tool in the fitness market, but minimal products target wheelchair users
A cadence-based field test can easily be applied in various custom settings
Self-monitoring of fitness may encourage wheelchair users to maximize their activity to improve their overall health
Application Functionality
In order to maximize the utility of our application, we employed the cadence-based fitness test model into the design
The application allows users to designate their personal specifications to their physical attributes i.e. Classification
A settings panel allows for customized controlling
Custom testing location and distance can be entered in order to determine fitness level outcome based on performance
A stepwise forward linear regression determines performance through either of the equations below1
At 60 pushes/min:
Peak VO2 (L/min) = (classification) (distance covered) – 0.15(RPE)
At 80 pushes/min:
Peak VO2 (L/min) = (distance covered) – 0.16(RPE) (classification)
Patient/user information can be stored on the host device through the SQLite Database in order to track individual progress
Conclusions & Implications
Easy access to fitness testing regardless of setting may improve wheelchair-user activity levels
The inclusion of our application in a clinical or domestic setting simplifies the tracking of patient development and assessment
Standardized testing to determine fitness will become more accessible to individuals of all mobility levels
We hope to further the profession of physical therapy through technology and provide self-monitoring opportunities for individuals of all mobility levels
