Muscle Grading
	5—Normal
	4—Good
	3—Fair
	2—Poor
	1—Trace
	0—no contractility
ROM, against gravity and against resistance

•	P46—Hip flexion—(T12), L1, L2, L3—iliopsoas
•	P48—Knee Extension—quads—L2, L3, L4—Femoral N.—extension lag—no full ROM, hard to raise last 10-15
•	P50—Hip adduction—L1, L2, L3, L4—Obturator N—Adductor brevis, longus, magnus

Dermatomes
•	T10—umbilicus
•	T11—
•	T12—
•	L1—
•	L4—medial leg
•	L5—lateral leg—dorsum of the foot
•	S1—lateral foot, lateral malleolus, and achilles tendon

•	Foot inversion—L4—Tibialis anterior, deep peroneal N—isometric test—tendon prominent when flexed

DTR—make sure joint is free and not locked or stretched

•	L5—Foot Dorsiflexion
•	Heel walking—properly done will see extensor tendons on the dorsum of the foot
•	Improperly can invert to compensate and wll see Tibilais anterior tendon
•	Hip Abduciton—L5—G. medius
•	S1—Achiles tendon (foot in neutral position)—peroneous
•	Superficial
•	Foot eversion
•	Plantar flexion of the foot
•	Hip extension—G. max—inferior gluteal

Cervical
•	C5
•	Epaulette—axillary nerve—pure innervation
