HIGH RISK CLASSIFICATION
Critical static loading detected. The subject maintained a fixed posture for 147 seconds (100% of session) with zero recovery breaks.
Combined with 98.3% Non-Neutral Trunk Posture and 100% High-Risk Neck Flexion, this profile indicates immediate risk of cumulative musculoskeletal strain.

Value
Zone / Status
Interpretation
Forward Head Posture (Ratio)
0.44
HIGH
Significant anterior skull migration. Increases effective head weight on C7/T1 by ~300%.
Trunk Asymmetry
41.7°
SEVERE
Dominant lean to RIGHT. Indicates monitor or input device is not centered.
Upper Arm Elevation
41.5°
HIGH
Shoulders elevated >35° for 72% of time. Keyboard/Desk likely too high.
4. Corrective Action Plan
Immediate: Micro-break Intervention. The "static bout" of 147s is the primary risk factor. Implement a timer to prompt movement every 20 minutes (20-20-20 rule).
Workstation Geometry. The 41.7° asymmetry and right-side dominance suggests the primary screen is offset. Center the monitor and keyboard to the user's midline.
Cervical Support. Neck flexion is consistently >60°. Raise the monitor height by at least 15-20cm to bring the top of the screen to eye level.
