Eleven patients reported significant improvements in quality of life, and 3 reported mild and transient adverse effects. Significant tremor improvement was observed on the FTM subscales: 63.6% at 12 months and 63.5% at the end of follow-up MDS-UPDRS tremor items showed improvements of 71.3% at 12 months and 60.3% at the end of follow up. Mean (standard deviation) follow-up duration was 30.0 (14.5) months. The maximum radiation dose administered was 130 Gy. ![]() Four patients were receiving anticoagulants and two had history of stroke. Median age was 78 years (range, 62-83), with seven patients aged over 75 years. Thirteen patients were registered, 6 with a diagnosis of tremor-dominant PD, four with refractory ET, and three with ET and PD. We analysed clinical and demographic variables, indication, radiation dose, effectiveness (based on subscales of the Fahn-Tolosa-Marin scale and the Movement Disorders Society-Unified Parkinson's Disease Rating Scale motor score), and adverse events. We reviewed the cases of patients treated with GKT between January 2014 and February 2018 with a minimum of 12 months’ follow-up. We describe the experience of Gamma Knife™ thalamotomy (GKT) in patients with essential tremor (ET) and tremor-dominant Parkinson's disease (PD) at our specialised stereotactic neurosurgery unit. Parkinsonism rating scales treatment response tremor.Unilateral Gamma Knife™ stereotactic radiosurgery on the ventral-intermediate nucleus of the thalamus is a minimally invasive neurosurgical option for refractory tremor. ![]() The Fahn-Tolosa-Marin Tremor Rating Scale has a better ability to capture changes due to levodopa challenge or antiparkinsonian treatment than MDS-UPDRS Part III or MDS-UPDRS Tremor Scale. However, Part A of the Fahn-Tolosa-Marin Tremor Rating Scale showed the highest effect size, which was a small one (Cohen's d = -0.33, η2 = 0.03), for detecting a treatment-related change in the severity of tremor during long-term follow-up. Part B of the Fahn-Tolosa-Marin Tremor Rating Scale was the most sensitive to acute levodopa challenge (Cohen's d = -1.04, η2 = 0.12). Changes in tremor scales were assessed by effect size values (Cohen's d and eta-square). To compare the sensitivity of the Fahn-Tolosa-Marin Tremor Rating Scale, the Part III of the Movement Disorder Society-sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the MDS-UPDRS Tremor Scale to the effects of various antitremor treatments.Įnrolling subjects with parkinsonism associated with tremor, we analyzed two scenarios: (1) tremor changes associated with acute levodopa challenge (n = 287) and (2) a 12-month outcome of different treatment options (n = 512) including deep brain stimulation (n = 146), levodopa/carbidopa intestinal gel infusion (n = 30), and initiating (n = 63) or adjusting oral antiparkinsonian medication (n = 273). ![]() However, the sensitivity to change of these instruments has remained to be clarified. Several scales are available for rating the severity of tremor at present. ![]()
