StairTest | McRoberts 2025

The StairTest provides an objective evaluation of stair ascent and descent—an essential component of daily mobility that is often challenging to measure accurately. Using the MoveTest, step cycles, timing, trunk kinematics, and movement dynamics are captured in detail for both directions. This enables clinicians and researchers to assess stair performance with greater precision than traditional stopwatch-based methods, and without the need for specialized lab equipment.

Key Outcomes

Total Duration

The total time required to ascend and descend the staircase is automatically calculated, replacing stopwatch-based timing with an objective and reliable measure.

Steps

The total number of steps taken during ascent and descent is detected and reported, providing a clear overview of step count and rhythm throughout the task.

Sub Durations

Durations of key phases—rise and stance cycles for both ascent and descent—are identified separately, offering detailed insight into movement control across the stair negotiation process.

Step Frequency

Step frequency (Hz) is calculated for ascent and descent, reflecting cadence and the overall tempo of stair climbing and descending.

Trunk Angle

Trunk flexion and extension angles are derived for each step cycle, providing information on postural strategy and control during both upward and downward movement.

Power Generation

Power output during ascent and descent is estimated from sensor-derived movement dynamics, offering an objective measure of functional strength during stair negotiation.
