Key facts

Psoas ( so -as)

Long, thick and deep pelvic muscle

Attaches to the anterior transverse processes of TI2-L5 (twelfth thoracic to fifth lumbar vertebrae) to the inside of the top of the femur at the other end

Flexes the thigh

The iliacus and psoas muscles are often considered as one and may be referred to as iliopsoas

Both muscles are primary flexors of the thigh and therefore serve to advance the leg in walking

Iliacus

(i-lee-ak-us)

Large, fan-shaped muscle deeply situated in the pelvic girdle

Attaches to the iliac crest at one end and to the inside of the top of the femur at the other end

Flexes and laterally rotates the femur

IN PRACTICE

In the case of muscular disorders it is important to avoid any methods of treatment that could increase the inflammatory response in the acute stage of the condition.

IN PRACTICE

With carpal tunnel syndrome avoid localised massage to the wrist if there is acute inflammation present in the area. In a chronic state this condition can be helped by elevating the limb to encourage lymph drainage, localised massage to loosen scar tissue and passively moving the elbow, wrist and fingers in order to maintain the range of movement. Remedial exercises such as passive stretching of the flexors and extensors of the wrist can be helpful in aiding this condition.

IN PRACTICE

In the case of a client with fibromyalgia it is best to advise gentler treatment applications of a shorter duration.
