Abstract:
Chronic back pain is one of the most common reasons for missed work and visits to the doctor. This report presents 2 interesting cases of chronic back pain that were effectively relieved by low-dose levodopa. These 2 patients showed no sign of anatomical problem of the spine or relative structures, but the discomforts on the back manifested some characteristics resembling those in restless legs syndrome (RLS), and one of them actually developed RLS after many years of back problem. We believe that this type of chronic back pain might be a variant of RLS, which we would like to call "restless back", and it can be effectively treated by dopaminergic drugs.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
