Treatment effect on intensity related measures for the rest and postural condition, measured values. A and D Tremor intensity (TI). B and E Peak power (Pow_peak). C and F Peak power (Freq_peak). T-PEMF = transcranial pulsed electromagnetic fields. REF = healthy reference group. * = significant difference from week 0 to week 8 across treatment groups (P ≤ 0.05). ⁽*⁾ = tendency of difference from week 0 to week 8 across treatment groups (0.05 < P ≤ 0.1). ^# = significant difference between the treatment groups combined at week 0 and REF (P ≤ 0.05)
