The effects of performing a one-legged bridge with hip abduction and use of a sling on trunk and lower extremity muscle activation in healthy adults.

The participants were healthy adults, so the results may not apply to people with back pain, limb deformity, severe surgical or neurological disease, trauma, or recent pain. The sample was small, and the authors stated the results cannot be generalized. Only the erector spinae, external oblique, gluteus maximus, and biceps femoris were measured, so other muscles were not compared. The authors noted a learning effect could not be excluded because participants performed all conditions. The study measured muscle activation, not strength, pain, function, or patient outcomes.

Do not use these findings to choose a bridge exercise for a patient as if improved muscle activation means improved strength, pain, or function. The study measured electrical muscle activity in healthy adults only, not patient outcomes.
