Action Observation Therapy in the Subacute Phase Promotes Dexterity Recovery in Right-Hemisphere Stroke Patients

Table 1

Outcome measure score changes are displayed as percentages of recovery potential (effectiveness indices) at the end of the treatment (T1) and 4-5 months afterwards (T2).

The results of between-group comparisons, by treatment and by lesion side, are reported. EG: experimental group; CG: control group; FM: Fugl-Meyer; BBT: Box and Block Test. RH: right hemiparetic; LH: left hemiparetic.
