Scores are based on the Bain and Findley tremor severity scale for rest (R), postural (P), kinetic (K) and intention (I) components. T denotes the cumulative tremor score (i.e. R+P+K+I). Postoperative tremor severity has not been assessed for three patients (Patients 8–10), in two of whom 6 months had not elapsed from the date of surgery (Bain et al., 1993). Pre and post refer to assessment timing with respect to surgery.
