Identifying Gower’s sign
To check for Gower’s sign, place the patient in the supine position and ask him to rise. A positive Gower’s sign – an inability to lift the trunk without using the hands and arms to brace and push – indicates proximal muscle weakness. 1Portable signs and symptoms by Lipincott Williams and Willkins
From the lying position, the patient rolls to the kneeling position, pushes on the ground with extended forearms to lift the hips and straighten the legs, so forming a triangle with hips at the apex and hands and feet on the floor forming the base. The hands are then used to push on the knees and so lift up the trunk (climbing upon yourself). 2A dictionary of neurological signs by A.J. Lamer
Patho-mechanics of Gower’s sign
With most of the trunk weight resting on the extended arms, they push the body backward to shift the weight of the trunk over the extended legs. To extend the hip, the child places their hands onto the knees and walks the arms up the thighs until upright. Children with mild disease may not even need a hand on the knee as they are able to bend at the hips once the knees are extended. 3Chang RF, Mubarak SJ.

Causes of Gower’s sign
Gower’s sign is typically seen in cases of pelvic muscle weakness or proximal muscle weakness.
- Muscular dystrophies
- Spinal muscular atrophy (SMA)
- Proximal ascending pseudomyopathic diseases
- Polymyositides
- Discitis
- Juvenile idiopathic arthritis (JIA)
Importance of Gower’s sign
A child continuing Gower’s maneuver after 3 years of age is likely to have a neuromuscular condition.

- Sensitivity: moderate (56%) 4Specificity and sensitivity of identifiers specific to clinical lumbar spine instability – C Demoulin et.al
