Development and Validation of an Exercise Programme for Recovery Balance Impairments in Poststroke Patients

Deterioration of balance is one of the most common and disabling physical-motor deficits in patients after a stroke that have a negative impact on quality of life and increase the risk of falls. Previous studies have evaluated the effectiveness of the exercises on specific aspects of balance. However, there is no structured exercise program divided by levels for balance impairment in poststroke patients.

Delphi method was used to design the exercise programme, and then a pilot study was performed. For the pilot study, we included 14 poststroke adults patients (n = 7 in each group), with balance impairment, without previous severe functional dependence, sensorial deficit or dementia. Our 4 weeks intervention (5 times/week) is based on 9 exercise of progressive difficulty, offering a multidimensional approach training (biomechanical constraints, stability limits, anticipatory, postural responses, and sensory orientation). Patients in the intervention arm received 45 minutes of usual rehabilitation plus 15 minutes of the intervention proposed. The usual-care arm received 60 minutes of usual rehabilitation. Balance impairment (Mini BESTest) was assessed at the baseline and at 4 weeks. Differences between groups were analysed using Mann-Whitney U test.

The agreement for the intervention designed was reached after 2 rounds. Participants in pilot study were 69 (SD = 9.7) years, 21.4% females. Post-treatment, median improvements in Mini BESTest were 20 (SD = 8) and 11 (SD = 10) points, P < .01 for intervention and control group respectively.

A multidimensional approach of balance impairments in poststroke patients through the validated exercise programme proposed, may improve balance deficits.
