Spinal Level	Motor Involvement	Sensory Involvement	Motor Reflexes
C-2	Tetrapalegia; can not breathe unassisted	No sensation below upper region of neck	None
C-6	Shoulder function, elbow flexion, wrist extension intact. No lower limb function	Neck, posterior lateral arm, radial forearm unaffected	Biceps, Brachioradialis
Thoracic Spinal Cord	Complete use of neck and upper limb. Lower limb paraplegia	Neck, upper limb intact. Lower limb anesthesia. Thorax and abdomen - depends on level injured	Biceps, Brachioradialis, Triceps
L-2	Hip flexion and some adduction possible	Portion of anterior and medial thigh intact. No sensation in remainder of limb	No lower limb reflexes. Incontinence
L-4	Hip flexion, adduction and knee flexion normal	Anterior, medial thigh; medial leg and foot normal	Patellar Incontinence
S-1	Hip, knee and ankle dorsiflexors normal. Ankle plantar flexors intrinsic muscles of foot weak	Perineum lacks sensation; most of lower limb has sensation	Pateller; Achilles Incontinence

Level of spinal cord injury is indicated by the highest level that remains intact. For
example, a C3 lesion means that the dermatomes and myotomes associated with C to C3
are intact. All those below C3 are affected. Likewise, an L4 lesion means that all
dermatomes and myotomes located at L4 and above are intact. Those below L4 (L5
through S4) are not.
