Box plot of proprioceptive error after rTMS applied at various scalp sites. The coil was placed over three different brain sites: M1, at the motor hotspot; APC, at 3 cm posterior to the motor hotspot; and PPC, at 6 cm posterior to the motor hotspot. The effect of rTMS site on proprioceptive error was significant (Kruskal-Wallis test, p = 0.023). Post-rTMS error is expressed as percentage of the baseline error, sampled before rTMS. n = 15 subjects in each group.
