Standing Trunk Rotation Assessment

Introduction

The Standing Trunk Rotation Assessment evaluates rotational mobility and control in the upper trunk and hips. This assessment is essential for identifying limitations or asymmetries that may impair performance or increase injury risk in rotational activities.

Purpose and Functionality

Proper trunk and hip rotation is essential for effective transfer of force, balance, and coordination in rotational sports and everyday function. This assessment helps pinpoint restrictions that could lead to compensatory movement and injury.

What It Evaluates

Upper Trunk Rotation: Assesses thoracic spine mobility and core control during rotational movement, which is vital for many athletic and daily activities.

Hip Rotation: Evaluates the ability of the pelvis and hips to rotate, highlighting lower-body mobility and movement efficiency.

Neck Rotation Component

Neck rotation evaluates the cervical spine’s ability to rotate from side to side. It is essential for functional tasks like checking blind spots while driving or performing athletic movements that require head turning. Restricted neck mobility may indicate stiffness in the cervical joints or muscular imbalance, which can contribute to poor posture, tension headaches, or injury risk.

Neck rotation is measured by the angular difference between the nose and the shoulder alignment when rotating to each side. Rotation angles greater than 60° score 100%, less than 30° score 0%, and scores in between are scaled linearly.

Neck Rotation Scoring

Scoring:

Excellent
>60°
Good
45-60°
Fair
30-45°
Poor
<30°
