Quadriceps Strains
Predisposing Factors
Contact Sports
Any cardiovascular problem that leads to
decreased circulation
Obesity
Poor nutrition
Previous thigh injury
Poor muscle conditioning
Muscle fatigue
Mechanism of injury
Prolonged overuse
Violent single blow
Tension forces on the quad
muscles causing an
overstretch
Signs and Symptoms
Pain with knee extension and passive stretch
Muscle spasm
Swelling
Loss of strength
Crepitation
Point tenderness over injury site
Ecchymosis
Defect in the muscle (third degree)
Examination and Evaluation
Palpation
– Rectus femoris
– Vastus lateralis
– Vastus medialis
– Vastus intermedius
Examination and Evaluation
Muscle Testing
– A, RROM Knee Extension
– A, RROM Hip Flexion
– Passive stretch quadriceps
muscle (combined knee
flexion and hip extension)
Classifications
Mild (Grade 1) – Slightly pulled without
tearing of muscle tendon or fibers. No loss
of strength
Moderate (Grade 2) – Tearing of fibers in
the muscle, tendon, or attachment to the
bone. Strength is diminished.
Severe (Grade 3) – Rupture of muscletendon-bone attachment with separation of
fibers. Requires surgical repair
Referral/Diagnostic Procedure
Orthopedic
surgeon –
for third degree.
Treatment and management
Cryotherapy –
knee flexed positon
Cold whirlpool
NSAIDS
Ultrasound
Massage
Rehabilitation
Stretching
Isometric muscle
contraction – Quad
sets
Straight leg raises
Knee extensions
Abduction exercises
Adduction exercises
PNF
Protection and Return to
Competition Factors
Sport specific strength and
conditioning program
Warm-up and cool-down
Protective equipment such
as thigh pads
Neoprene sleeve for
compression and support
