Abstract: BACKGROUND:The subjective postural vertical (SPV) is affected by training that requires participants to maintain balance; training to achieve sitting balance may also help SPV recovery and activities of daily living (ADLs). OBJECTIVE:This study aimed to assess the medium-term effects of balance training on the postural vertical (PV) and ADLs in patients with stroke. METHODS:Thirty-three patients with stroke were enrolled in this randomized crossover trial. The outcomes were SPV, SPV with eyes opened (SPV-EO), and the Functional Independent Measure (FIM) after the 14-day intervention of experimental or control training. Experimental training consisted of a maximum lateral truncal tilt to the paretic side at 0.25 Hz with or without a 10° wedge, repeated 60 times. Repeated-measures two-way analysis of variance was performed with two factors: intervention and the intervention period. RESULTS:There was no interaction between the control condition and the PV, but there was interaction between the intervention period and using a wedge for SPV variability errors. FIM showed an interaction between the intervention period and the use of a wedge. CONCLUSIONS:Balance training while sitting with a wedge significantly improved the SPV and FIM. This improved cognition and perception, which facilitate difficult dynamic tasks in ADLs.
