Impairment in toileting behavior after a stroke

Dependence for toileting is the most problematic aspect for patients after a stroke. However, the relative difficulty of each component of toileting and the predictors for independent performance of these activities are unknown. We investigated these issues in stroke patients using Boltzmann sigmoid and generalized linear modeling.

We carried out a cross-sectional correlation study, including 107 adult inpatients, hospitalized for a stroke. We assessed the activity components of toileting, as well as evaluated physical impairment using the Fugl-Meyer Assessment, impairments in balance using the Berg Balance Scale, cognitive impairments using the Mini-Mental State Examination and the presence or absence of unilateral spatial neglect or aphasia.

Boltzmann sigmoid modeling showed that the total scores required to obtain a response at 50% of the maximal value for the required components of toileting ranged between 2.691 and 34.962 points, for the components of "wearing pants" and "cutting the toilet paper," respectively. A generalized linear model showed that the Berg Balance Scale score was a significant predictor for independent performance on most component activities of toileting.

The component of toileting that was easiest to carry out was cutting the toilet paper, and the most difficult was wearing pants. Balance impairment was an independent predictor of independent toileting after stroke. This detailed toileting assessment enabled us to document the most difficult components of toileting, and to assess the motor and process skills required for independent toileting.
