Conservative management for hypertrophic scars (HSc) and scar contractures is of utmost importance to optimally reintegrate burn survivors into society. Many conservative treatment interventions have been described in the literature for the management of HSc. Recent advancements in the literature pertaining to postburn scarring and HSc formation have advanced our understanding of the mechanisms that support or refute the use of common rehabilitation treatment modalities after burn injury. This is particularly relevant for recent advancements in the fields of mechanotransduction and neurogenic inflammation, resulting in the need for rehabilitation clinicians to reflect upon commonly employed treatment interventions. The aim of this review article is to summarize and clinically apply the evidence that supports or refutes the use of common conservative treatment interventions for scar management employed after burn injury. The following treatments are discussed, and mechanotransduction and neurogenic inflammation concepts are highlighted: (1) edema management (compression, positioning/elevation, pumping exercises, retrograde massage, and manual edema mobilization); (2) pressure therapy (including custom fabricated pressure garments, inserts, face masks, and other low-load long-duration orthotic devices); (3) gels or gel sheets; (4) combined pressure therapy and gels; (5) serial casting; (6) scar massage; and (7) passive stretching. This review supports the following statements: (1) Compression for edema reduction should be initiated 48-72 hours postinjury and continued for wounds that require longer than 21 days to heal until scar maturation; (2) Elevation, pumping exercises, and retrograde massage/MEM should be used in combination with other edema management techniques; (3) Custom-fabricated pressure garments should be applied once the edema is stabilized and adequate healing has occurred. Garments should be monitored on a regular basis to ensure that optional pressure, >15 mm Hg, is maintained, adding inserts when necessary. The wearing time should be >16 hours/day; (4) Gels for postburn scar management should extend beyond the scar; (5) Serial casting should be applied when contractures interfere with function; (6) Forceful scar massage should be avoided early in the wound healing process or when the scar is inflamed or breaks down; and (7) Other treatment modalities should be prioritized over passive stretching for scar management.
