Overview

The SFMA (Selective Functional Movement Assessment) toe touch assessment evaluates the range of motion and quality of movement in the spine during forward bending. This assessment measures the ability to achieve sufficient hip flexion while maintaining proper alignment and identifying any compensations.

​
Instructions

From a standing position, bend forward and reach as low to the ground as possible while keeping your knees straight.

Notes

  • Kinematic data typically captured at 30-60 Hz for stability activities
  • Functional movement requires:
    • Knee flexion ROM ≤ 15°
    • Hips pass behind heels
    • Wrists pass below ankles
