Cumulative Injury CYCLE

Question 1

Injury cycle

List in order

Answer 1

CIC

Tissue trauma
Inflammation 
Muscle spasm
Adhesions
Altered neuromuscular control
Muscle Imbalance

Question 2

Davis Law

Answer 2

Soft tissues model around stress

Question 3

Pattern Overload

Answer 3

Repeating motion pattern over long period that can lead to dysfunction

Question 4

Petellofermoral pain syndrome

Answer 4

A musculoskeletal condition in which a client experiences pain behind and around the patella with running, squatting, jumping, or other physical activity.

Question 5

Petello tendinopathy

Answer 5

Often associated with jumper’s knee; commonly an overuse injury affecting the patellar tendon, resulting in anterior knee pain.

Question 6

IT band syndrome

Answer 6

Often associated with jumper’s knee; commonly an overuse injury affecting the patellar tendon, resulting in anterior knee pain.

Question 7

Screw home mechanism

Answer 7

In an open-chain position, as the knee extends during the last 30 degrees, the tibia will externally rotate on the femur to lock the knee into extension, making the ligaments taut (Floyd, 2017). In a closed-chain position, such as in a squat, the femur will internally rotate on the tibia (Kim etal., 2015), given that the foot is fixated on the ground.

Question 8

Extensor mechanism (knee)

Answer 8

Composed of the patellofemoral articulation, patellar tendon, quadriceps tendon, and tibial tubercle working together to produce concentric, eccentric, and isometric actions at the knee.

Question 9

Tri planer movement of ankle

Rear foot

Answer 9

Dorsiflexion + Foot abduction + Eversion = Pronation = Unlocked rearfoot = Force absorption
Plantar flexion + Foot adduction + Inversion = Supination = Locked rearfoot = Force production
