Summary
The iPronator app reliably detects mild arm weakness in stroke patients using handheld device accelerometers. This tool also effectively tracks functional recovery in acute stroke patients over one week.
Area of Science:
- Neurology
- Medical Technology
Background:
- The pronator drift test is a standard clinical assessment for detecting subtle arm weakness.
- Objective quantification of the pronator drift test is needed for improved diagnostic accuracy.
Purpose of the Study:
- To develop and validate a handheld device application, iPronator, for objective pronator drift testing.
- To assess the feasibility of iPronator in identifying mild arm weakness in acute ischemic stroke patients.
Main Methods:
- The iPronator application was developed using handheld device accelerometers.
- Acute ischemic stroke patients (n=10) and healthy controls (n=10) were enrolled.
- Measurements included average, maximum, and oscillation of drift and pronation, compared between groups and in follow-up.
Main Results:
- A strong correlation was found between pronation and drift measurements by iPronator (r=0.741, p<0.001).
- Stroke patients exhibited significantly greater average and maximum pronation and drift compared to controls (p<0.001).
- Follow-up in stroke patients showed improvements in pronation and drift within one week.
Conclusions:
- The iPronator application reliably detects mild arm weakness in stroke patients.
- iPronator is valuable for monitoring functional recovery in acute stroke patients over a one-week period.
