START BY BODY REGION
Shoulder & arm
Connect shoulder motion with scapular control, thoracic contribution, and the demands of reaching or loading.

Forward Head Posture
A forward head position is a common observation, not a diagnosis by itself. Use workstation changes and low-load movement to see whether comfort, control, or task tolerance improves.
Rounded Shoulders
Shoulders resting forward can reflect habit, task demands, anatomy, or fatigue. Resting appearance alone does not diagnose a problem; movement comfort and function matter more.
Scapular Anterior Tilt
The shoulder blade changes orientation as the arm moves, and resting position varies between people. Explore anterior tilt only when it accompanies pain, poor control, or limited reaching—not from appearance alone.
Shoulder Elevation
Shoulders naturally elevate during many reaching and loading tasks. Explore the pattern when it is paired with neck effort, pain, asymmetry, or reduced task tolerance rather than trying to keep the shoulders down at all times.
