Goal analysis in patients with limb spasticity treated with incobotulinumtoxinA in the TOWER study

To map spasticity-related goals using the International Classification of Functioning, Disability and Health (ICF) linking rules, and review goal syntax to direct future goal setting.

1633 treatment goals, set during the TOWER study, were linked to the ICF framework and EQ-5D domains. Goals were mapped independently by two investigators with expertise in ICF linking rules.

In total, 1630 (99.8%) goals could be mapped to the ICF (inter-rater agreement on the main ICF category 96.1%). Most goals (80.2%) were mapped to a single ICF category and were related to activities/participation (54.9%). 170 (10.4%) goals were related to general tasks and activities, such as positioning, stretching, and strengthening. In total, 1072 goals (65.6%) mapped to the EQ-5D domains (inter-rater agreement 90.8%). Analysis of the goal syntax highlighted the need to include a verb in patient-centered goals to direct active behavior.

The ICF offers a broad framework for setting patient-centered, easily understandable goals for patients with spasticity, including goals related to (guided) self-management activities. This analysis sheds new light on patient needs and could direct future goal-driven botulinum toxin spasticity treatment focused on enabling patients to better manage activity limitations imposed by their body function impairments.Trial registration: NCT01603459 registered with ClinicalTrials.gov (https://clinicaltrials.gov/ct2/show/NCT01603459).Implications for RehabilitationThe ICF offers a broad framework for setting patient-centered, easily understandable goals for patients with spasticity.ICF domains that include general tasks and demands can be used to establish goals relating to (guided) self-management of spasticity.An ICF-based goal-setting framework may increase the comparability of clinical data across studies.
