【 摘 要 】

Resting tremor is the characteristic motor sign in Parkinson’s disease (PD), predominantly affecting the upper extremity, unilaterally. The rest tremor can appear in other body regions at 4–6 Hz frequencies [1, 2]. It typically starts in the distal part of the upper extremity and then progresses proximally and to the other extremities over time [3]. However, isolated tremors in one lower limb can also be an initial manifestation of PD. Unilateral leg tremor in PD patients mostly involves the foot, and similar to those in upper extremities, it can evolve into thigh muscle resulting in a whole leg movement [4]. On the contrary to this steady rule of a distal-proximal gradient in parkinsonian resting tremor, we here to describe three patients with PD presented with unusual, isolated leg tremor starting from a thigh muscle without involving distal part of the leg, thereby extending our knowledge on the clinical features of parkinsonian resting tremor appearing in a leg.
