TherEx | Quad Sets, Straight Leg Raises (SLRs) & Progressions

The video tutorial explains the importance of quadricep exercises, focusing on quad sets and straight leg raises. It highlights the conditions under which these exercises are beneficial, such as severe pain or limited knee motion. The tutorial details the steps for performing a quad set, emphasizing ankle dorsiflexion and quadriceps contraction. It then progresses to the straight leg raise exercise, which involves additional muscles like the iliopsoas group. The seated straight leg raise is also covered, offering a greater range of motion and increased difficulty. Resistance options like therabands and ankle weights are suggested for progression.

Under which condition is a quadriceps exercise particularly recommended?

• When the patient has a high pain tolerance

• If the patient is allowed to bear weight on the lower extremity

• If the patient can only move through a small range of motion at the knee joint

• When the patient has no pain

What is the first step in performing a quad set exercise?

• Dorsiflexion of the ankle

• Contracting the quadriceps

• Relaxing the muscles

• Flexing the hip

How long should the quadriceps contraction be maintained during a quad set?

• 10 seconds

• 20 seconds

• 5 seconds

• 15 seconds

Which additional muscle group is involved in the straight leg raise exercise?

• Hamstrings

• Iliopsoas

• Gluteus maximus

• Calf muscles

What distinguishes the straight leg raise exercise from the quad set?

• It requires no muscle contraction

• It is an isometric exercise

• It only uses the quadriceps

• It involves hip flexion

What is a benefit of the seated straight leg raise exercise compared to the supine version?

• It requires less effort

• It is easier to perform

• It covers a larger range of motion at the hip joint

• It does not involve the quadriceps

How can the difficulty of the straight leg raise exercises be increased?

• By reducing the range of motion

• By doing them without dorsiflexion

• By using theraband resistance or ankle weights

• By performing them faster
