The combination of heat and the dependent position, as experienced with a standard lower extremity whirlpool treatment, has the potential of encouraging lower extremity swelling. This study examined the effects of whirlpool and the dependent position on lower extremity swelling in 40 healthy physical therapy students and therapists (12 males, 28 females) between the ages of 20 and 40 (= 24.3 yrs). Volumetric measurements were taken before and after three experimental conditions. Condition number one involved a 20-minute treatment in a leg whirlpool at 40 degrees C (104 degrees F). The second condition involved sitting for 20 minutes with the foot resting on the bottom of an empty leg whirlpool. The third condition involved a 20-minute rest in the supine position. A one-way ANOVA and Tukey's post hoc test were used to analyze the data. Analysis revealed the greatest increase in limb volume following the whirlpool treatment (= 44 ml +/- 30.5). The second greatest increase (= 20.5 ml +/- 32.5) occurred when the extremity was maintained in the dependent position. When placed in the supine position, subjects experienced a decrease in limb volume (= -16 ml +/- 15.2). The findings were statistically significant at the 0.01 level. The results indicated that while lower extremity swelling does occur from treatment in a whirlpool or by placing the extremity in a dependent position, the changes seen are not as dramatic as those reported in the upper extremity. The variation is hypothesized to be due to physiological and anatomical differences between the upper and lower extremities. Caution is advised, however, when using whirlpool to treat lower extremity injuries in the presence of significant musculoskeletal or vascular pathology because marked swelling could result.

在标准下肢涡流治疗中，热和依赖位置的结合有可能导致下肢肿胀。本研究检查了涡流和依赖位置对 40 名健康物理治疗学生和治疗师（12 名男性，28 名女性）下肢肿胀的影响，年龄在 20 至 40 岁之间（= 24.3 岁）。在三种实验条件下，分别在治疗前和治疗后进行体积测量。第一种条件是在 40°C（104°F）的腿部涡流中进行 20 分钟的治疗。第二种条件是在脚放在空的腿部涡流底部的情况下坐 20 分钟。第三种条件是在仰卧位休息 20 分钟。使用单向方差分析和 Tukey 的事后检验分析数据。分析显示，涡流治疗后肢体体积增加最多（= 44 毫升 +/- 30.5）。当肢体处于依赖位置时，体积增加第二大（= 20.5 毫升 +/- 32.5）。当处于仰卧位时，肢体体积减少（=-16 毫升 +/- 15.2）。研究结果在 0.01 水平上具有统计学意义。结果表明，虽然下肢涡流治疗或肢体依赖位置会导致下肢肿胀，但与上肢相比，变化并不明显。这种变化被假设是由于上下肢之间的生理和解剖差异。然而，在存在明显的肌肉骨骼或血管病理学的情况下，使用涡流治疗下肢损伤时应谨慎，因为可能会导致明显肿胀。J Orthop Sports Phys Ther 1992;16(4):169-173.
