Task intensity influences upper limb and torso kinematics during two common overhead Functional Capacity Evaluation...

Area of Science:

• Biomechanics
• Occupational Health
• Kinesiology

Background:

• Functional Capacity Evaluation (FCE) is crucial for return-to-work processes.
• Visual observation of mechanics during FCE tasks informs treatment and decision-making.
• Understanding kinematic changes with increasing intensity is vital for accurate assessments.

Purpose of the Study:

• To identify kinematic differences between sexes during common FCE tasks.
• To establish normative movement behaviors across varying intensity levels.
• To provide objective data for Functional Capacity Evaluations.

Main Methods:

• Collected upper limb and torso kinematics from 30 participants.
• Analyzed overhead lift and overhead work tasks at different intensities.
• Calculated joint angles and segment velocities, using mixed model ANOVA for statistical analysis.

Main Results:

• Increased torso flexion/extension and humeral flexion with load during overhead lift.
• Humeral flexion, axial rotation, and wrist extension increased over time during overhead work.
• Observed kinematic changes correlated with increasing task intensity.

Conclusions:

• Task intensity significantly influences kinematic variables during overhead FCE tasks.
• Objective kinematic data enhances the reliability of determining safe patient capacities.
• Identified compensatory actions can be detected through kinematic analysis.
