Table 3 Summary of suggested measures, functions, and design features (usability, wearability) of prospective wearable monitoring technology

From: Perspectives on the prospective development of stroke-specific lower extremity wearable monitoring technology: a qualitative focus group study with physical therapists and individuals with stroke

MeasuresFunctions
• Muscle activation detection• Video-pairing
• Gait measurements• Bluetooth connectivity
 - Timing of muscle activation• Detects bilaterally
 - Compensatory pattern detection• Integrate data with medical records
 - Heel contact• Ability to manipulate data
 - Temporospatial features• Remote programming and data access
 - Kinematic features• Raw and processed data
 - Toe trajectory• Comparison to normative data
 - Stride length• Continuous feedback/readings
• Heart rate monitoring• Biofeedback
• Weight bearing - Audio (multiple pitches)
• Symmetry - Lights (colour-coded)
• Differentiate activation vs. tone - Vibration
• Differentiate concentric vs. eccentric - On handheld device
• Force and loading - Numeric feedback
• Step counts - Customisable (volume, cues)
UsabilityWearability
• Desired variable selection• Small size, inconspicuous
• Reproducible set-up• Lightweight
• Phone interface• Cosmetically pleasing
• Laptop interface• Simple disinfection
• Simple/reusable calibration• Donning/doffing with one arm
• Malfunction alert• Visual cue at wrist
• Turns on upon application 
• Usable with one hand 
• Customisable app 
• Good battery life
