Rest Before Physical Therapy Is Not Necessary to Achieve Bony Healing of Lumbar Spondylolysis in Adolescent Athletes

Listen to this summary

The authors aimed to determine whether initiating physical therapy (PT) immediately after a diagnosis of lumbar spondylolysis negatively affects bony healing in adolescent athletes. Their randomized controlled trial found that 81% of participants showed healing on MRI after three months, with no significant difference in outcomes between those who started PT immediately and those who rested before beginning therapy. The results suggest that prolonged rest is unnecessary, as immediate PT does not hinder healing and is associated with better pain outcomes.
