In Ontario, only about 10% of compensation patients with low back pain are disabled more than six weeks and hence tend to have chronic complaints. Six hundred and twenty-three such patients were studied to determine the distribution of diagnoses and to test the effectiveness of various programs of conservative therapy.Two hundred and thirteen patients were assigned in rotation to one of four treatments. The results were inconclusive. In 70% of these, the pain was due to intervertebral disc degeneration with added trauma.Two hundred and sixteen patients were assigned randomly to a treatment involving mild exercise, or one with vigorous exercise. Neither was found to be superior. In 76% of these, the pain was due to disc degeneration with added trauma.Using 194 patients, the results of treatment in the Compensation Board Rehabilitation Centre were compared with those obtained by treatment at home. Satisfactory improvement was achieved in 15 of 95 treated at home, and in 42 of 99 in the Centre. The failure of treatment in six of each 10 cases indicates that present-day methods of management of such patients are unsatisfactory.
在安大略省，只有约10%的因背痛而获得赔偿的患者残疾超过六周，因此往往会有慢性疼痛症状。对623名此类患者进行了研究，以确定诊断分布情况并测试各种保守治疗方案的有效性。213名患者被轮流分配到四种治疗方法中的一种。结果尚无定论。其中70%的患者疼痛是由于椎间盘退变并伴有额外创伤所致。216名患者被随机分配到轻度运动治疗组或剧烈运动治疗组。结果发现两种治疗方法都没有优势。其中76%的患者疼痛是由于椎间盘退变并伴有额外创伤所致。以194名患者为对象，将赔偿委员会康复中心的治疗结果与在家治疗的结果进行了比较。在家接受治疗的95名患者中有15名取得了满意的改善，在康复中心接受治疗的99名患者中有42名取得了满意的改善。每10例中有6例治疗失败，这表明目前对此类患者的治疗方法并不令人满意。
