SLR Straight-Leg Raise

An SLR in Supine combines Dynamic Hip Flexion with an Isometric Contraction of The Quadriceps.

The greatest Resistance is Encountered During The First Few Degree of SLR

PRIMARY MUSCLE - The Rectus Femoris is the Primary Muscle in the quadriceps group that is Active During SLR exercise.

How to perform SLR

Patient Position - Supine with affected leg's knee extended

Opposite Hip And knee are flexed and foot placed flat on exercise Table - To stabilise The pelvis and Low back

Procedure - first Patient Set quadriceps muscle by SQE(static Quadriceps) then lift the leg about 45° of Hip Flexion While keeping The Knee in extension

Then hold the position for a count of 10 and lower it.

For progression of SLR have the Patient Lift to only 30° And Then To only 15° of hip Flexion and hold the position.

At later stage to increase resistance place the cuff weight around the patient's ankle.

If The Patient cannot perform an SLR because of a Quadriceps lag or weakness go for Straight Leg Lowering

STRAIGHT LEG LOWERING

PATIENT POSITION - Begin By Passively placing The leg in 90° of SLR position ( or as Far as The Flexibility Of The Hamstring Allows)

Procedure - Tell Patient To Gradually Lower The extremity While Keeping The Knee Fully Extended.

Precaution - Be prepare to control The descent of the Leg With Your hand Under The Heel as The torque Created By Gravity Increases.

If Knee begins To Flex As The Extremity Is Lowering, Have the patient stop at that Point then Raise The Extremity upward to 90 and Tell patient to repeat That motion and attempt to lower the extremity a little farther each Time while keeping the knee extended

When patient can keep the knee extended while lowering the leg through the full Rom (Range Of Motion) SLRs can be initiated..

Knee Joint Assessment & Biomechanics

In this post we have covered following topics. 1). Common Deviation of knee joint 2).Assessment Process 3). How knee is related to ankle foot and hip Lumbo-Pelvic Girdle. Common Deviations 1. Side to Side Alignment (e.g., a valgus knee) 2. Tracking problem during flexion and extension.. Side to Side Alignment is the alignment of the femur and tibia and the movement and position of these bones in relation to the Centre line of the body. A. when the knee collapses in toward the midline of the body(a valgus position) B. toward the outside of the body (a varus position); Tracking Problems of the knee during flexion and extension can occur when the kneecap does not glide smoothly over the bottom of the femur (femoral groove). Tracking problems place an abnormal amount of pressure on the underside of the kneecap. Over time, this excessive pressure can cause inflammation and irritation, res...

Assessing The Thoracic Spine & Shoulder Girdle

COMMON DEVIATIONS There are four main deviations that can cause pain, injury, and movement dysfunction in the thoracic spine and shoulder girdle. Excessive Thoracic Kyphosis Protracted Shoulder Girdle Internally Rotated Arms Elevate Scapula Our thoracic spine naturally has a mild forward-shaped curve called a kyphotic curve. A greater than normal curvature of the thoracic spine is known to as excessive Thoracic kyphosis . Excessive thoracic kyphosis disturb the function of the entire shoulder girdle. A protracted shoulder girdle occurs when the scapula (shoulder blades) move forward on the rib cage, causing their vertebral borders (the edges closest to the spine) to move away from the spine. Protraction of the shoulder blades also protracts the entire shoulder girdle, moving the acromion's and collarbones forward and out of alignment. When the shoulder girdle protracts, it affects the position of the glenohumeral joint, causing the upper arm to rotate inward tow...
