Se evaluo la gravedad del temblor con la escala FTM la discapacidad en el miembro superior, con la escala Disabilities of the Arm, Shoulder and Hand (DASH), y la calidad de vida relacionada con la salud, con el cuestionario Short Form-36 Health Survey (SF-36). Estudio observacional transversal en pacientes diagnosticados de temblor esencial. Analizar la validez y la fiabilidad de la version en castellano de la escala FTM. Hasta ahora no existe una validacion formal de la version española de la escala Fahn-Tolosa-Marin (FTM), usada ampliamente para valorar la gravedad del temblor.
The Spanish version of FTM the rating scale is a reliable and valid tool to evaluate disability in patients with essential tremor, and a suitable instrument for use in medical research, as well as in clinical practice.Įstudio de validacion de la version española de la escala Fahn-Tolosa-Marin para el temblor esencial. The FTM (subscale C) showed high correlations with DASH, and acceptable diagnostic capacity, with an area under the curve of 0.86 (95% CI: 0.67-1.00), sensitivity 78% and specificity 75% for a cut-off score > 5.5. Internal consistency of the FTM was high: Cronbach's alpha: 0,90 (subscale A: 0.85 subscale B: 0.91 subscale C: 0.77), and the floor and ceiling effects were negligible.
Statistical analysis included sample description, reliability (Cronbach's alpha), convergent validity, and discrimination capacity tests (ROC curves).įorty patients with essential tremor (22 women, 18 men) were included, with a mean age of 65.8 ± 14.7 years (range: 21-90 years).
Upper limb disability was evaluated by terms of Disabilities of the Arm, Shoulder and Hand Scale (DASH), and to health-related quality of life using the Short Form-36 Health Survey (SF-36). To provide support to the validity and reliability of this version of FTM Scale.Ī cross-sectional study was conducted on essential tremor patients.
However, a Spanish language version of this scale has still not been formally validated. The Fahn-Tolosa-Marin (FTM) tremor rating scale has been widely used in clinics for the estimation of tremor severity.
