Methods and Tools Used for the Measurement of Burn Scar Contracture

Abstract

After burn injury, scar contracture can cause significant impairment and functional deficit. Many studies have investigated the treatment and prevention of burn scar contracture, but few studies have focused on the methods for measuring contracture. The purpose of this study was to determine whether consistent and objective methods of measurement are used to quantify scar contracture in the clinical evaluation of burn patients and in burn research. A survey was administered to 407 burn therapists to determine the methods and tools used clinically to measure scar contracture, while a review of recent burn literature was conducted to determine the methods and tools used in burn research. The results of the survey indicate that there is a lack of consensus in the methods and tools used for the measurement of scar contracture, both clinically and in research. Instead, a variety of measurement methods was reported, each with varying degrees of objectivity. Clinically, the methods are rarely checked for reliability or performance competency. In burn research, the methods and tools vary, and contracture data obtained are often reported in an inconsistent manner. If the measurement of scar contracture is not done objectively and consistently, then it is difficult to determine reliability, validity, and responsiveness of the measurement methods. Development of standard protocols with reliable measures of scar contracture would improve the quality of burn care and research.

A Pilot Prospective Randomized Control Trial Comparing Exercises Using Videogame Therapy to Standard Physical Therapy

“…22 Goniometry measures ROM in a single plane of movement, therefore these measurements are referred to in this paper as "planar ROM." Standard and consistent goniometric methods 23 were used by a single investigator to measure active and passive motion.…”

Refining the Idiom “Functional Range of Motion” Related to Burn Recovery

“…Complex joint kinematic measurements extracted using three-dimensional system measurements is difficult to apply to a clinic setting because the primary measuring device for ROM used in a burn rehabilitation setting is a standard goniometer. 57 A standard goniometer was only used in one study that was included in this literature review. 19 Future investigations could involve a literature review on other reported functional outcome measures that have been validated in persons with burn injuries.…”

Utilidad clínica de la zetaplastia de cuatro colgajos en secuelas de quemadura

“…Al igual que otros autores, hemos observado que efectivamente se pueden levantar colgajos aun en zonas de quemadura o en zonas injertadas, logrando muy buenos resultados, tal como se reporta en la literatura. 10,13,14 Se ha publicado recientemente otras técnicas de zetaplastias modificadas, como la zetaplastia de siete colgajos, con una mayor ganancia de elongación tisular. 15 La principal desventaja tal vez en este tipo de cirugías es que, en ocasiones, puede haber necrosis en el vértice de los colgajos, aunque sea parcial y ofrece poca liberación en los casos de bridas interdigitales, para los que la primera opción se pudiera realizar colgajos trapezoidales.…”
