Monitored physical activities in patients with adolescent idiopathic scoliosis (AIS) have been shown to improve physical performance, endurance and cardiopulmonary function and may be assessed by the 6-min walk test (6MWT). We aimed to evaluate the long-term results of the 6MWT after a rehabilitation protocol employed before surgical correction for AIS.
This prospective randomized clinical trial studied the impact of a 4-month pre-operative physical rehabilitation protocol on post-operative cardiopulmonary function and physical endurance, by using the 6MWT, in patients with AIS submitted to surgical correction, comparing them to matched controls without physical rehabilitation. Studied variables were heart and respiratory rate, systolic and diastolic blood pressure, peripheral blood oxygen saturation, Borg score, and distance walked. Patients were assessed at baseline, after 4 months of rehabilitation, and 3, 6 and 12 months post-operatively.
A total of 50 patients with AIS were included in the study and allocated blindly, by simple randomization, into either one of the two groups, with 25 patients each: study group (pre-operative physical rehabilitation) and control group. The physical rehabilitation protocol promoted significant progressive improvement in heart and respiratory rate, peripheral blood oxygen saturation, distance walked, and level of effort assessed by the Borg scale after surgery.
Post-surgical recovery, evaluated by 6MWT, was significantly better in patients who underwent a 4-month pre-operative physical rehabilitation protocol.
青少年特发性脊柱侧凸（AIS）患者的监测体育活动已被证明可改善身体机能、耐力和心肺功能，并且可以通过6分钟步行试验（6MWT）进行评估。我们旨在评估AIS手术矫正前采用康复方案后6MWT的长期结果。
这项前瞻性随机临床试验通过6MWT研究了4个月术前身体康复方案对接受手术矫正的AIS患者术后心肺功能和身体耐力的影响，并将其与未进行身体康复的匹配对照组进行比较。研究变量包括心率、呼吸频率、收缩压和舒张压、外周血氧饱和度、博格评分和步行距离。在基线、康复4个月后以及术后3、6和12个月对患者进行评估。
共有50例AIS患者纳入研究，并通过简单随机化被盲目分配到两组中的一组，每组25例：研究组（术前身体康复）和对照组。身体康复方案使术后心率、呼吸频率、外周血氧饱和度、步行距离以及通过博格量表评估的努力程度有显著的逐步改善。
通过6MWT评估，接受4个月术前身体康复方案的患者术后恢复情况明显更好。
