This study examined the efficacy of behavioral strategies in alleviating pain and anxiety associated with severe orthopedic trauma. Sixty-four patients with multiple fractures were divided into four groups: (1) control, (2) attention only, (3) EMG biofeedback-assisted relaxation, and (4) audiotaped relaxation training. All were measured over at least six sessions, or as long as hospital stay permitted. Significant between group differences were found on the following: systolic blood pressure, peripheral temperature, subjective units of discomfort, state anxiety, with a trend for use of sleep medications. No differences were found on other vital signs, EMG recordings, or other medications. EMG-biofeedback relaxation and relaxation training were relatively equivalent for all measures, and little or no change was observed for those patients who received attention only or served as controls.
本研究考察了行为策略在减轻与严重骨科创伤相关的疼痛和焦虑方面的疗效。64名多处骨折患者被分为四组：(1) 对照组，(2) 仅接受关注组，(3) 肌电图生物反馈辅助放松组，(4) 录音放松训练组。所有患者均至少接受六次测量，或在住院时间允许的情况下尽可能长时间测量。在以下方面发现了显著的组间差异：收缩压、外周温度、主观不适单位、状态焦虑，以及使用睡眠药物的趋势。在其他生命体征、肌电图记录或其他药物方面未发现差异。肌电图生物反馈放松和放松训练在所有测量指标上相对等效，而仅接受关注或作为对照组的患者几乎没有或没有观察到变化。
