BackgroundThe relationship between freezing of gait (FOG) and levodopa response is complex. Some patients respond, some have no response and in some patients levodopa causes FOG. We present 2 cases demonstrating a diphasic worsening of FOG after levodopa dosing.CasesTwo PD patients with FOG were examined during the practically definedoffstate, the transition fromofftoon(15 and 22 minutes postdose), and in the fullonstate (45 and 60 minutes postdose). FOG was measured using Movement Disorder Society–Unified Parkinson's Disease Rating Scale part III, item 11: freezing of gait. Both patients experienced worsening of FOG during the transition followed by improvement during theonstate. Case 1 had serum levodopa levels measured. Videos are provided.ConclusionsTo our knowledge, this diphasic pattern of worsening of FOG has not been previously reported. The cause of this phenomenon is unknown but may relate to an inhibitory action of subthreshold levels of levodopa.
