PAMSys Gait™
Continuous monitoring of gait and mobility during activities of daily living
A single ankle-worn sensor that precisely detects individual steps and measures detailed gait metrics — stride duration, stride length, and walking velocity — continuously during everyday life, for up to 3 months on a single charge.
Clinical gait assessments capture only a snapshot of mobility during a brief clinic visit — often in controlled environments that don't reflect real-world walking. Patients may perform differently at home, where terrain, fatigue, medication timing, and daily routines all affect gait. PAMSys Gait provides a continuous, ecologically valid window into how patients actually move during daily life, revealing patterns and changes that episodic clinical evaluations miss.
Comprehensive stride-level metrics from daily life
PAMSys Gait extracts detailed gait parameters from every walking bout, including average, median, 90th percentile, and 95th percentile statistics for each measure.
Stride velocity
Walking speed per stride (m/s)
Stride length

Time per stride cycle (s)
Steps per bout
Steps within each walking bout
Stride velocity variability

Daily and cumulative step count
Beyond the clinic
PAMSys Gait captures what episodic clinical evaluations cannot — real-world mobility in the context of everyday life.
Single ankle-worn sensor
Lightweight, unobtrusive design worn on one ankle. Validated algorithms automatically compensate for sensor orientation changes during daily activities.
Up to 3 months battery
Depending on deployment configuration, PAMSys Gait operates continuously from 2 weeks to 3 months — capturing weeks of real-world gait data without recharging.
High-frequency raw data
Captures raw IMU sensor data alongside processed gait metrics, enabling custom algorithm development and retrospective analysis by research teams.
Ecologically valid
Measures gait during real daily activities — at home, in the community, across different terrains and conditions — not just in controlled clinic corridors.
Detects subtle changes
Stride variability metrics can identify emerging gait impairment before it becomes clinically apparent, enabling earlier intervention and more sensitive clinical trial endpoints.
Complementary to PAMSys
While PAMSys (pendant) monitors overall physical activity and posture, PAMSys Gait provides granular stride-level gait analysis — together they deliver a complete mobility picture.
