Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the change in TETRAS PS scores and composite of TETRAS PS + ADL scores after receiving oral propranolol starting from dose of 40 mg to a maximum dose of 240 mg or the maximum tolerated dose at the end of 4 weeks and 8 weeks of stable dose. A clinically meaningful reduction in tremor will be defined as a 30% reduction in TETRAS PS score as well composite TETRAS PS + ADL score from the baseline. Timepoint: At the end of 4 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. At the end of 8 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) To assess the change in ataxia severity using SARA scores after receiving oral propranolol starting from dose of 40 mg to a maximum dose of 240 mg or the maximum tolerated dose at the end of 4 weeks and 8 weeks of stable dose.Timepoint: At the end of 4 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. At the end of 8 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol.;2) To assess the change in health related quality of life using SF 36 questionairre after receiving oral propranolol starting from dose of 40 mg to a maximum dose of 240 mg or the maximum tolerated dose at the end of 4 weeks and 8 weeks of stable dose.Timepoint: At the end of 4 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. At the end of 8 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol.;3) To assess the change in quantitative assessment of tremor severity, frequency and characteristics using surface EMG and accelometry after receiving oral propranolol starting from dose of 40 mg to a maximum dose of 240 mg or the maximum tolerated dose at the end of 8 weeks of stable dose.Timepoint: At the end of 4 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. At the end of 8 weeks of stable dose i.e 240 mg or maximum tolerated dose of propranolol. | — |
