Hip Abduction Sign
Hip Abduction Sign
The hip abduction sign refers to abduction of the thighs when attempting to rise from the ground, due to relative weakness of hip adductors with preserved strength in hip abductors. The sign was first described in patients with sarcoglycanopathies, a group of autosomal recessive limb-girdle muscular dystrophies, and is reported to have a sensitivity of 76% and a specificity of 98% for this diagnosis. It may perhaps be envisaged as the equivalent to Gowers’ sign but with hip adductor, rather than gluteal, weakness.
