Acceleration (or G) induced arm pain may develop in centrifuge runs and in flight with low arm position and assisted pressure breathing during G (PBG) in combination with an extended coverage anti-G suit. To decrease this arm pain, pressurized sleeves and gloves were developed.
Eight subjects who earlier exhibited G-induced arm pain were tested on the centrifuge. The G-exposures consisted of a gradual onset run up to a maximum of +9 G2, rapid onset runs to +3, +4, +5, +6, +7, +8, and +9 Gz and a simulated aerial combat maneuver (SACM) with peaks up to +9 Gz. On separate days, the subjects were tested without the sleeves and gloves, and with the sleeves and gloves pressurized to a maximum of 40, 60, or 80 mmHg at +9 Gz. The subjects reported their left and right arm pain on a subjective rating scale.
G-induced arm pain, usually starting above +6 Gz, was often the reason for termination of the G-exposure without the pressurized sleeves and gloves. The pressurized sleeves and gloves significantly (p < 0.001) decreased arm pain, put no significant difference was found among the different pressures used. Heart rate was not different with and without the pressurized sleeves and gloves.
The pressurized sleeves and gloves are an effective method to alleviate and sometimes eliminate G-induced arm pain.
在离心机运转以及飞行过程中，当手臂处于低位且采用辅助加压呼吸（PBG）并结合延长覆盖式抗荷服时，可能会出现加速度（或G值）诱发的手臂疼痛。为了减轻这种手臂疼痛，研发了加压袖套和手套。
选取8名先前曾出现过G值诱发手臂疼痛的受试者在离心机上进行测试。G值暴露包括逐渐增加至最大+9G2的递增过程、快速增加至+3、+4、+5、+6、+7、+8和+9Gz的过程以及峰值高达+9Gz的模拟空战机动（SACM）。在不同日期，让受试者分别在不使用袖套和手套、以及在+9Gz时将袖套和手套加压至最大40、60或80mmHg的情况下进行测试。受试者通过主观评分量表报告其左右手臂的疼痛情况。
G值诱发的手臂疼痛通常在+6Gz以上开始出现，这常常是在不使用加压袖套和手套的情况下终止G值暴露的原因。加压袖套和手套能显著减轻手臂疼痛（p<0.001），但在不同使用压力之间未发现显著差异。使用和不使用加压袖套和手套时心率无差异。
加压袖套和手套是减轻甚至有时消除G值诱发手臂疼痛的有效方法。
