CAD Pointing Device Modification

Addressing severe tendonitis & inability to grip

Typical causal relatonship mouse - mouse shown used by left hand due to severe pain in right hand

Excessive grip on stylus when first introduced flaring hand, wrist & arm pain

Standard CAD mouse with highly repetitive button activation triggered severe tendonitis resulting with inability to grip

Custom foam surround installed on digitizing pad stylus (replacing mouse) with swivel arm support enabling CAD without pain

Positoning over digitizing pad allows unencumbered hand / wrist movement

Swiverl forearm support allows full forearm rest without undue pressure on extensor tendons

Low level grip force offloads tendons from excessve movement and tension

Right index finger extensor tendonitis with referent upper extremity pain secondary to repeated button clicking

Inability to grip and move hand without pain

Cannot effectively perform CAD drafting activities

CAD pointer operation requires repeated finger flexion / extension triggering symptomology

Replace mouse with digitizing stylus

Encapsulate stylus with large foam handle increasing hand contact area and reducing force transmission thorough fingers

Implement forearm supports to promote neutral shoulder / elbow / wrist posturing reducing static muscle contraction

Ability to perform CAD activities
