A patient with complete C6 tetraplegia is learning transfers. Which method matches the available musculature?
- ASliding-board transfer using momentum and the head-hips relationship
- BIndependent standing pivot transfer with a hemi-walker for support
- CDependent mechanical lift transfer for all surfaces and situations
- DLateral push-up transfer using triceps to lift and clear the trunk
Show answer and rationale
Correct: A. C6 provides wrist extension and tenodesis grasp but no triceps, so a sliding board with momentum and the head-hips relationship is the achievable independent method. Lateral push-up transfers require C7 triceps.
- D — Triceps innervation begins at C7, not C6.
- B — Standing pivot requires lower-limb motor function absent in complete tetraplegia.
- C — C6 complete injury is compatible with independent transfers, so a lift underestimates the potential.
