RESUMO
BACKGROUND: Scar contracture is a well-known sequela of burns that is specifically relevant as it may limit function. Reports regarding the course of scar contractures, however, are scarce and, moreover, not focussed on function. This study describes the course of prevalence of scar contractures that limit function in children and adolescents after burns. METHOD: Range of motion (ROM) of extremity joints of 20 children and adolescents after burns were assessed at discharge (T0) and at six weeks (T1), three months (T2), and six months (T3) after discharge. A scar contracture limiting function was defined as a measured ROM lower than the functional ROM, i.e., ROM used to perform daily activities by unimpaired subjects. RESULTS: At discharge (T0), 89.5% of the subjects had one or more scar contractures that limited function. Six months later (T3), this prevalence was 76.5%. At discharge (T0), less function limiting scar contractures were found for the upper extremity (29.7%) than the lower extremity (53.3%). Over time, prevalence of contractures in both extremities fluctuated between 22% and 35%. CONCLUSIONS: The majority of children and adolescents (13/17) still had scar contractures limiting function six months after discharge (T3). Substantial longitudinal studies over a longer period of time are needed to increase our knowledge on the course of these scar contractures in order to support improvements in burn care. TRIAL REGISTRATION: The study is approved by the Regional Committee for Patient-Oriented Research Leeuwarden in the Netherlands (NL45917.099.13).

BACKGROUND: To evaluate the effect of (new) treatments or analyse prevalence and risk factors of contractures, rating scales are used based on joint range of motion. However, cut-off points for levels of severity vary between scales, and it seems unclear how cut-off points relate to function. The purpose of this study was to compare severity ratings of different rating scales for the shoulder and elbow and relate these with functional range of motion. METHODS: Often used contracture severity rating scales in orthopedics, physiotherapy, and burns were included. Functional range of motion angles for the shoulder and elbow were derived from a recent synthesis published by our group. Shoulder flexion and elbow flexion range of motion data of patients three months after a burn injury were rated with each of the scales to illustrate the effects of differences in classifications. Secondly, the shoulder and elbow flexion range of motion angles were related to the required angles to perform over 50 different activities of daily living tasks. RESULTS: Eighteen rating scales were included (shoulder: 6, elbow: 12). Large differences in the number of severity levels and the cut-off points between scales were determined. Rating the measured range of motions with the different scales showed substantial inconsistency in the number of joints without impairment (shoulder: 14-36%, elbow: 26-100%) or with severe impairment (shoulder: < 10%-29%, elbow 0%-17%). Cut-off points of most scales were not related to actual function in daily living. CONCLUSION: There is an urgent need for rating scales that express the severity of contractures in terms of loss of functionality. This study proposes a direction for a solution.

OBJECTIVE: Burn scar contractures are the pathological outcome of excessive scarring and ongoing scar contraction. Impairment of joint range of motion is a threat to performing activities in daily living. To direct treatment strategies to prevent and/or correct such contractures, insight into the prevalence, course, and determinants is essential. METHODS: A literature search was conducted including Pubmed, Cochrane library, CINAHL, and PEDro. Articles were included if they provided burn scar contracture data to calculate the point prevalence. The quality of the articles was scored. Data were extracted regarding study, subject and burn characteristics, method of scar contracture assessment, point prevalence, and possible determinants. RESULTS: Nine articles and one abstract could be included for data extraction. The prevalence at discharge was 38-54%, but with a longer time after burn, the prevalence was lower. Contractures were more likely to occur in more severe burns, flame burns, children, female, the cervical spine, and the upper extremity. CONCLUSIONS: The prevalence of burn scar contractures varies considerably between studies. When prevalence is unclear, it is also difficult to investigate potential determinants and evaluate changes in interventions. There is a need for extensive, well-designed longitudinal (inter)national studies that investigate prevalence of scar contractures, their evolvement over time, and risk factors.
