“The Rukoo Test” of the Lumbar Spine: A Potential Diagnostic Tool for Sciatica

Abstract

Lower back pain is a prevalent condition among adults, affecting a significant portion of the population. Non-specific back pain is
experienced by over 85% of individuals, while approximately 40% will develop low back pain with sciatica (radiculopathy along the
distribution of the sciatic nerve) at some point in their lives [1].Accurate physical examination plays a crucial role in differentiating
between lower back pain and sciatic nerve compression, aiding in the diagnosis of sciatica [2]. The straight leg test, also known
as the Lasègue test, is commonly used in neurosurgical clinics to assess patients for sciatic nerve irritation [3]. A positive straight
leg test often indicates lumbar disc herniation, but its specificity and sensitivity may vary [4]. It can also yield positive results in
conditions such as facet joint cysts or hypertrophy. Consequently, introducing an additional test with improved sensitivity would be
beneficial for more accurate diagnosis. The Forward Flexion Test of the Lumbar Spine has emerged as a potential diagnostic tool
for assessing the presence of sciatica and its underlying causes.In this study, we propose referring to it as the "Rukoo Test."
