Brief Summary

This study will compare standing balance in adults ages 18 to 50 during normal standing, inward anchoring, and outward anchoring. Anchoring involves standing with the feet wider than shoulder width and trying to pull the legs together or push them apart without moving the feet. Participants will complete all three conditions in a randomly assigned order. A researcher will use a handheld force-measuring instrument at six points on the pelvis to measure how much pressure participants can resist before a foot lifts from the floor. Participants will also rate how stable they feel after each anchoring condition. The first 18 participants will repeat assessments to evaluate measurement consistency. Participation is expected to last 60 minutes, or 90 minutes for those completing repeat assessments.

Outcome Measures

Primary Outcomes (8)

Mean Break-Point Force at the Right Anterior Superior Iliac Spine
A microFET2 handheld dynamometer is applied at the right anterior superior iliac spine during normal stance, inward anchoring, and outward anchoring. Force in newtons is recorded when the sole of the foot closest to the tester leaves the floor. Three readings are collected per stance
Day 1
Mean Break-Point Force at the Left Anterior Superior Iliac Spine
A microFET2 handheld dynamometer is applied at the left anterior superior iliac spine during normal stance, inward anchoring, and outward anchoring. Force in newtons is recorded when the sole of the foot closest to the tester leaves the floor. Three readings are collected per stance.
Day 1
Mean Break-Point Force at the Right Iliac Crest
A microFET2 handheld dynamometer is applied at the right iliac crest during normal stance, inward anchoring, and outward anchoring. Force in newtons is recorded when the sole of the foot closest to the tester leaves the floor. Three readings are collected per stance
Day 1

A microFET2 handheld dynamometer is applied at the left iliac crest during normal stance, inward anchoring, and outward anchoring. Force in newtons is recorded when the sole of the foot closest to the tester leaves the floor. Three readings are collected per stance.
Day 1
Mean Break-Point Force at the Right Posterior Superior Iliac Spine

Day 1
Mean Break-Point Force at the Left Posterior Superior Iliac Spine
A microFET2 handheld dynamometer is applied at the left posterior superior iliac spine during normal stance, inward anchoring, and outward anchoring. Force in newtons is recorded when the sole of the foot closest to the tester leaves the floor. Three readings are collected per stance.
Day 1
Perceived Stability Rating After Inward Anchoring
After inward anchoring, participants answer how stable they felt during that stance. Ratings range from 0 (not at all stable) to 10 (completely stable); 5 means neutral, or the same stability as normal standing. Higher scores indicate greater perceived stability.
Day 1
Perceived Stability Rating After Outward Anchoring
After outward anchoring, participants answer how stable they felt during that stance. Ratings range from 0 (not at all stable) to 10 (completely stable); 5 means neutral, or the same stability as normal standing. Higher scores indicate greater perceived stability

Normal Stance → Inward Anchoring → Outward Anchoring

EXPERIMENTAL

Participants complete normal stance, then inward anchoring, then outward anchoring. The same force assessments are performed in each condition, with two minutes of rest between conditions.
