Lower limb functional status and its determinants in moderate/major burns 3-6 months following injury: A two-center observational study

Abstract

Introduction: Severe complications which may cause impaired physical functionoften develops over time following severe burn to the lower extremities. The purpose of this study was to clarify the clinical determinants of lower limb functional status, functional mobility and exercise capacity in moderate/major burns 3-6 months following the injury.Methods: The study included 42 patients, 12 with moderate injury and 30 with major injury, aged 19-59 years old. Lower Limb Functional Index was used to determine the lower limb functional status. Functional mobility and exercise capacity were evaluated with the Timed Up and Go test and the 6-min walk test, respectively. Scar quality and kinesiophobia were assessed with the Patient and Observer Scar Assessment Scale (POSAS) and the Tampa Scale for Kinesiophobia, respectively. Active range of motion (ROM) was measured with a universal goniometer.Results: Significant and independent predictors of lower limb functional status, functional mobility and exercise capacity related to POSAS score, kinesiophobia level, gender, burn severity, the number of operations, the presence of burnsinvolving any of the lower limb joints, knee ROM limitations, limitation in any of the lower limb joint ROMs, comorbidities, and truncal burns (p < 0.05).Conclusions: Burn characteristics and clinical evaluations of patients are important determinants of the lower limb functional status, mobility and exercise capacity in burn patients. These predictors should be considered to improve physical functions related to the lower limb when creating a personalized rehabilitation program.
