Evidence Checklist: Carpal Tunnel Syndrome

EMG/nerve conduction study (NCS) confirming median nerve entrapmentCritical

Objective electrodiagnostic testing documenting prolonged median nerve distal motor and sensory latencies across the carpal tunnel. This is the primary objective evidence for the VA.

Nexus opinion linking carpal tunnel syndrome to service ("at least as likely as not")Critical

Medical opinion connecting your CTS to repetitive military duties (typing, wrench work, vibrating tools, heavy lifting) or a service-connected condition like hypothyroidism or diabetes.

Grip and pinch strength testing

Documented grip dynamometry and pinch gauge measurements comparing both hands, showing functional loss from median nerve dysfunction.

Documentation of dominant vs. non-dominant handCritical

Medical records noting which hand is dominant. Under DC 8515, the major (dominant) hand/arm receives a higher rating.

Treatment records (bracing, injections, surgery)

Records of wrist splints, corticosteroid injections, or carpal tunnel release surgery, with post-operative functional outcomes.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Peripheral Nerves ConditionsCritical

VA standardized form capturing sensory loss, motor weakness, and functional impairment for rating under DC 8515 (median nerve, carpal tunnel).

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
