Dear Editors, It is convenient to use a commercial cooling device for treatment of acute athletic injuries. However, secondary injuries may develop with improper application (1). We present a patient with unusual frostbite due to cold pack. An 18-year-old woman had right quadriceps femoris muscle strain while practicing long jump. She directly applied and fixed a commercial cold pack manufactur...

IMPORTANCE Cold panniculitis is a self-limited condition, manifesting as erythematous plaques or nodules after cold exposure, that typically affects infants and children. Recently, a variant involving the lateral thighs of equestrians has been described. Since the original report of this variant, some confusion has arisen in the literature in which the terms equestrian cold panniculitis and equ...

Abstract Introduction Platelet-rich plasma (PRP) has gathered great momentum in surgery. The main outcome of the study was to assess whether there a difference growth factor release from PRP with addition vitamin C, cooling, or both C and cooling. Method Blood samples 10 volunteers were centrifuged produce PRP. Activated autologous thrombin produced platelet-poor (PPP), which added activate it....

STUDY DESIGN Two-factor repeated measures design. OBJECTIVES To compare the effects of a 20-minute cold application to the effects of a 20-minute cold application followed by 20 additional minutes of intermittent cold on forearm blood flow over a 60-minute period. BACKGROUND The appropriate duration of cold application as a therapeutic modality following soft tissue trauma is an important c...

Trust lies at the heart of person perception and interpersonal decision making. In two studies, we investigated physical temperature as one factor that can influence human trust behavior, and the insula as a possible neural substrate. Participants briefly touched either a cold or warm pack, and then played an economic trust game. Those primed with cold invested less with an anonymous partner, r...

BACKGROUND It is well known that reducing tissue temperature changes sensory and motor nerve conduction. However, few studies have compared the effect of different cold modalities on nerve conduction parameters. OBJECTIVE The purpose of this study was to compare the effects of ice pack, ice massage, and cold water immersion on the conduction parameters of the sural (sensorial) and tibial moto...

We report the results of three high-powered, independent replications of Study 2 from Williams and Bargh (2008). Participants evaluated hot or cold instant therapeutic packs before choosing a reward for participation that was framed as a prosocial (i.e., treat for a friend) or self-interested reward (i.e., treat for the self). Williams and Bargh predicted that evaluating the hot pack would lead...
