Abstract:
Primary orthostatic tremor (POT) may be a cause of postural instability in older people. Though unusual, this condition is relatively easily diagnosed, based in part on typical clinical features, impacts on quality of life, and is amenable to symptomatic treatment (Heilman KM. Orthostatic tremor. Arch Neurol 1984; 41: 880-1). We present three cases seen in a general neurology clinic over a 15-month period to highlight the typical clinical features which should alert clinicians to the possibility of this diagnosis.

Muscles that Move the Leg
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 to...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
