Calcium metabolic balance determinations, which have been done in various clinical and experimental conditions, were applied to the study of 8 spinal cord injured patients receiving a diet with 1600 mg calcium and 85 to 120 gm protein daily. All of the patients had hypercalciuria prior to ambulation. Those with spinal cord injuries of less than 3 months duration (early group) had a calcium balance of -27 mg before ambulation and 235 mg after ambulation. Patients with spinal cord injuries of 6 months or more duration (late group) had calcium balances of 55 mg before ambulation and 175 mg after ambulation. Ambulation significantly decreased the hypercalciuria and modified the calcium balance in a positive direction. Smaller changes were noted in the responses of the late group than in those of the early group. Early ambulation will probably prevent bone loss, calcium stones in the genitourinary tract, and other sequellae of negative calcium balance.
在各种临床和实验条件下进行的钙代谢平衡测定，被应用于对8名脊髓损伤患者的研究，这些患者每日摄入含1600毫克钙和85至120克蛋白质的饮食。所有患者在能够行走之前都有高钙尿症。脊髓损伤持续时间少于3个月的患者（早期组）在能够行走之前钙平衡为 -27毫克，行走之后为235毫克。脊髓损伤持续6个月或更长时间的患者（晚期组）在能够行走之前钙平衡为55毫克，行走之后为175毫克。行走显著减少了高钙尿症，并使钙平衡朝着积极方向改变。晚期组的反应变化比早期组小。早期行走可能会预防骨质流失、泌尿生殖道钙结石以及钙负平衡的其他后遗症。
