51 patients with sacroiliac joint-related leg pain were randomized to independently examine the short-term effects of physiotherapy, manual therapy, and intra-articular injection, over 12 weeks. The therapies were evaluated based on the success rates of each treatment, which was defined by complete relief of complaints at 6 or 12 weeks, and VAS score for average pain at 12 weeks lower than baseline values. Additionally, patients were assessed using VAS and RAND-36. The evidence presented in this study demonstrated that manual therapy had a significantly better success rate compared to physiotherapy. No significant differences were apparent between intra-articular injection and manual therapy or between physiotherapy and intra-articular injection when comparing the outcomes assessed.
