Cryotherapy or moist heat packs (MHP) are often used prior to static stretching to enhance range of motion (ROM). Their influence on ROM when applied prior to proprioceptive neuromuscular facilitation-contract relax (PNF-CR) stretching is unknown. The purpose of this study was to determine if an ice bag or MHP influenced passive hip flexion ROM prior to PNF-CR stretching. When compared to the control, all treatment groups had a large effect. Participants receiving MHP PNF-CR, PNF-CR only, and ice bag PNF-CR met or exceeded our meaningful detectable change, thus demonstrating increased ROM. Those receiving an ice bag or MHP only did not demonstrate improvements and failed to present with ROM improvements.
