Treatment effect on inter-hand coherence measures for the rest and postural condition, measured values. A and D Coherence (Coh). B and E Peak coherence (Cohpeak). C and F Frequency of peak coherence (Cohfreq). T-PEMF = transcranial pulsed electromagnetic fields. REF = healthy reference group. * = significant difference from week 0 to week 8 across treatment groups (P ≤ 0.05). # = significant difference between the treatment groups combined at week 0 and REF (P ≤ 0.05). (#) = tendency of difference between the treatment groups combined at week 0 and REF (0.05 < P ≤ 0.1)
