Exercise is considered an effective treatment strategy for non-specific chronic low back pain (NSCLBP).background In spite of the wide use of exercise protocols, it is not clear what type of exercise is more effective in decreasing pain, disability and normalizing muscle activation patterns in people with chronic low back pain.
To assess the effects of two exercise protocols (stabilization vs movement control) on pain and disability scores and the flexion relaxation ratio (FRR) of lumbar multifidus (LM) and iliocostalis lumbarum pars thoracic (ICLT) in people with extension related non-specific chronic low back pain.
Pilot randomized control trial.
32 subjects with active extension pattern chronic low back pain (stabilization group = 16, movement control group = 16) participated in this study. Treatment groups received 4 weeks of exercise therapy. Outcomes were based on pain score (Numeric rating Scale-NRS), disability (Oswestry Disability Index- ODI) and FRR of the LM and ICLT.
Four people dropped out of the study in each group for reasons unrelated to the protocols of the study. Pain and disability reduced in both groups, with no significant difference between the groups. The FRR of LM did not change in either treatment group after treatment. However, the FRR of ICLT was significantly increased after treatment in the movement control group.
Both movement control and stabilization exercises reduced pain and disability in the short-term among people with extension pattern NSCLBP, with no difference in effectiveness between the groups. However, movement control exercises were more effective in normalizing back muscle activation patterns than stabilization exercises.
运动被认为是治疗非特异性慢性下腰痛（NSCLBP）的有效策略。尽管运动方案被广泛使用，但尚不清楚哪种类型的运动在减轻慢性下腰痛患者的疼痛、残疾以及使肌肉激活模式正常化方面更有效。
评估两种运动方案（稳定化训练与动作控制训练）对伸展相关的非特异性慢性下腰痛患者的疼痛和残疾评分以及腰多裂肌（LM）和胸腰髂肋肌（ICLT）的屈伸松弛率（FRR）的影响。
先导性随机对照试验。
32名有主动伸展型慢性下腰痛的受试者（稳定化训练组 = 16名，动作控制训练组 = 16名）参与了本研究。治疗组接受了4周的运动疗法。结果基于疼痛评分（数字评定量表 - NRS）、残疾程度（奥斯威斯利残疾指数 - ODI）以及LM和ICLT的FRR。
每组各有4人因与研究方案无关的原因退出研究。两组的疼痛和残疾程度均有所减轻，组间无显著差异。治疗后，两个治疗组的LM的FRR均未改变。然而，动作控制训练组治疗后ICLT的FRR显著增加。
在有伸展型NSCLBP的人群中，动作控制训练和稳定化训练在短期内均能减轻疼痛和残疾程度，两组的效果无差异。然而，动作控制训练在使背部肌肉激活模式正常化方面比稳定化训练更有效。
