CAD Pointing Device Modification

Addressing severe tendonitis & inability to grip

Problem

Right index finger extensor tendonitis with referent upper extremity pain secondary to repeated button clicking. Inability to grip and move the hand without pain.

Issue

Cannot effectively perform CAD drafting activities. CAD pointer operation requires repeated finger flexion/extension triggering symptomology.

Solution

Replace mouse with digitizing stylus. Encapsulate stylus with large foam handle increasing hand contact area and reducing force transmission through fingers. Implement forearm supports to promote neutral shoulder/ elbow/wrist posturing reducing static muscle contraction.

Result

Ability to perform CAD activities.
