Prehabilitation and preoperative exercise in adolescent idiopathic scoliosis surgery: a systematic review.
Review in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2026.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity that can lead to physical and psychological distress, requiring surgical treatment for severe AIS. Exercise has been proposed as a conservative treatment or postoperative rehabilitation. Yet, the effectiveness of preoperative exercise and prehabilitation in improving surgical outcomes remains unclear. PURPOSE: This systematic review evaluates the effectiveness of preoperative exercise and prehabilitation in improving surgical outcomes and analyzes which outcomes showed significant improvement.
methodsSix major databases were searched for studies published before June 2025. Studies recruiting AIS patients aged under 18 undergoing surgeries and performing preoperative exercise or ERAS protocols involving preoperative exercise are included. Outcomes include pain level, hospitalization time, postoperative complications, curve correction, spine flexibility, cardiopulmonary function, re-admission and quality of life.
resultsNine studies with 574 patients were included, comprising 329 patients as exercise-intervention group and 245 patients receiving no intervention or other preoperative interventions. The average age was 14.86 ± 2.78 [CI: 14.63, 15.09] and mean Cobb angle was 65.59°±13.47° [CI: 64.49, 66.69]. The exercise-intervention group showed lower postoperative VAS scores than control. The average length of hospital stay was 2.5 days shorter in the exercise group compared to control (4.15 [CI: 4.04, 4.26] vs. 6.65 [CI: 6.29, 7.01]). The exercise group also demonstrated fewer postoperative complications (Rate: 5.2% vs. 18.5%), improvement in spine flexibility (from 0.39 to 0.66), better cardiopulmonary function and higher quality of life. The mean rate of re-admission of exercise-intervention groups is 0.9%.
conclusionPreoperative exercise has been shown to improve postoperative pain, length of stay, complications, cardiopulmonary recovery, and quality of life. Although its effect on objective surgical correction outcomes remains uncertain, incorporating preoperative exercise into AIS surgical care may enhance recovery experience and functional outcomes. However, given the significant heterogeneity among studies, further research and clinical trials are needed to standardize implementation protocols and outcome measures, as well as to conduct subgroup analysis based on baseline severity and spinal flexibility.
