Italian translation and transcultural validation of an assessment tool for community ambulation in stroke survivors: the modified Functional Walking Categories (mFWC).

BACKGROUND

Community ambulation ability is one of the most important functional loss after stroke. The assessment of the level of community walking plays an important role in the multidimensional bio-psycho-social approach, to improve quality of life and social participation of stroke survivors. The modified Functional Walking Categories (mFWC) is a worldwide widely used tool to assess community ambulation in stroke survivors, but no Italian version is yet available.

OBJECTIVE

To cross-culturally adapt the mFWC into Italian and to assess its validity and reliability.

METHODS

According to the international guidelines, a multistep translation and cultural adaptation were conducted and revised by a committee of experts. Patients admitted to intensive inpatient rehabilitation with a sub-acute stroke were recruited. Inter- and intra-rater reliability and construct validity were studied.

RESULTS

Sixty patients with sub-acute stroke were prospectively enrolled in this study. Findings showed almost perfect intra- and inter-rater reliability (k = 1.000 [95% CI 1.000-1.000] and k = 0.984 [95% CI 0.955-1.000], respectively). The construct validity of the scale was satisfactory, as 100.0% hypotheses were met.

CONCLUSIONS

The Italian mFWC offers a valid tool for measuring community ambulation in stroke patients. Our work provides a validated and a cross-cultural adapted Italian version of the mFWC to accurately measure community ambulation both in clinical and research settings in Italy.
