Berg balance scale as a tool for choosing the walking aid for patients with Guillain-Barré syndrome or polyneuropathy.

Berg balance scale (BBS) is a widely used outcome measure in rehabilitation. We wanted to check if it can discriminate among levels of use of walking aid in patients with Guillain-Barré syndrome or polyneuropathy. A retrospective audit of 109 such patients (aged 16-85 years) who had completed inpatient rehabilitation in the period 2012-2017 was conducted. Receiver operating characteristic curve analysis was used to estimate the thresholds that optimise the prediction of the patient's walking aid. Statistically, significant threshold BBS score was estimated for the ability to walk without walking aid (≥49 points, yielding 88% sensitivity, 68% specificity and 83% classification accuracy) and the necessity to walk with a walker (≤37 points, yielding 62% sensitivity, 83% specificity and 78% classification accuracy). BBS score thresholds can therefore help clinicians choose the appropriate walking aid for patients with Guillain-Barré syndrome or polyneuropathy undergoing rehabilitation.
