Background:
The Functional Assessment for Control of Trunk (FACT) was developed to evaluate trunk function after stroke. However, only a few studies used FACT to show functional outcome.
Objective:
This study aimed to validate the FACT predictive ability for functional outcome following stroke and create an English version of the FACT.
Methods:
This retrospective, observational study was conducted with patients aged≥65 years with stroke. Patients were divided into two groups according to the median FACT score at admission: trunk impairment or high trunk function group. Multiple regression analysis was performed for Functional Independence Measure (FIM) gain and FIM efficiency to examine the relationship between trunk function assessed by FACT at admission and functional prognosis.
Results:
105 participants (mean age, 80.2±7.6, 57.1%were men) were included. Of these, 48 (45.7%) and 57 (54.3%) were categorized to the trunk impairment group and high trunk function group, respectively. FACT score at admission was associated with FIM gain (coefficient = 0.875, P = 0.001) and FIM efficiency (coefficient = 0.015, P = 0.016) after adjusting for confounders.
Conclusions:
Trunk impairment at admission assessed by FACT could predict functional prognosis. The English version of FACT was created and further demonstrated the validity of FACT.
