Context: Therapeutic modalities are routinely administered to increase flexibility, but the relative effects of different modes of tissue heating on passive range of motion (PROM) are unknown. Objective: To assess the relative effects of active exercise on a stationary bicycle, moist hot pack treatment, and warm whirlpool treatment on hip flexion PROM. Design: Repeated measures. Subjects: 24 males and 20 females between the ages 18 and 24 years. Main Outcome Measure: Hip flexion PROM measured by an inclinometer. Results: Repeated measures analysis of variance identified a significant difference among the heating methods, F(l, 43) = 32.41; p < .001. Active exercise produced the greatest change in hip flexion PROM. Conclusions: All three treatment methods produced an increase in hip flexion PROM, but active exercise produced a significantly greater increase than moist hot pack and warm whirlpool treatments.

    Context: Laser therapy is purported to improve blood flow in soft tissues. Modulating circulation would promote healing by controlling postinjury ischemia, hypoxia, edema, and secondary tissue damage. However, no studies have quantified these responses to laser therapy. Objective: To determine a...
