简要总结
Excessive foot pronation has been recognized as being linked to chronic low back pain (CLBP). The use of compensating custom-made foot orthoses has not been entirely explored as an effective therapy for CLBP Objective: to investigate the effects of wearing custom made foot orthoses compared to placebo orthoses in patients with pronated feet and chronic low back pain (CLBP).
详细描述
Excessive foot pronation has been recognized as being linked to CLBP. Foot hyperpronation may cause malalignment of the lower extremity.There is a wide variety of treatments for CLBP, and it is suggested that excessive pronation of the foot has been linked to CLBP.The use of compensating custom-made foot orthoses has not been entirely explored as an effective therapy for CLBP.
Customized foot orthoses alter the position of the foot during weight-bearing. The goal is to eliminate compensation of the foot due to structural deformity or misalignment and redistribute abnormal plantar pressures.Custom-made foot orthoses may contribute to improving chronic low back pain. This question represents an important benefit for patients and for the public health system by reducing expensive treatments, such as surgery or long periods of rehabilitation

结局指标
主要结局
Oswestry Disability Index Questionnaire(ODI) for Lower Back Pain
时间窗: Baseline
This questionnaire has been designed to give us information as to how your back or leg pain is affecting your ability to manage in everyday life.The test is considered the 'gold standard' of low back functional outcome tools 0% to 20%: minimal disability: The patient can cope with most living activities. 21%-40%: moderate disability: The patient experiences more pain and difficulty with sitting, lifting and standing. Travel and social life are more difficult and they may be disabled from work. Personal care, sexual activity and sleeping are not grossly affected and the patient can usually be managed by conservative means. 41%-60%: severe disability: Pain remains the main problem in this group but activities of daily living are affected. These patients require a detailed investigation. 61%-80%: crippled: Back pain impinges on all aspects of the patient's life. Positive intervention is required. 81%-100%: These patients are either bed-bound or exaggerating their symptoms.
VAS for Chronic Low Back Pain
时间窗: Baseline
10 visual analogue scale (VAS).The findings suggested that 10 VAS ratings of no pain (0-2), mild pain(2-4), moderate pain (4-7), and severe pain (7-10)
Foot Posture Index
时间窗: At the moment of inclusion in the study
Foot posture was assessed by a podiatrist during the biomechanical assessment based on the six-item foot posture index (FPI≥+6). The FPI consists of six validated items that are measured in a relaxed standing position of the subject. Each item is assessed on a -2 to +2 scale, where -2 indicates a supinated position, 0 indicates a neutral position and +2 indicates a pronated position, depending on the specific item. The sum of the scores of the six items provides a total score ranging from -12 to +12.
次要结局
- Oswestry Disability Index Questionnaire (ODI)(at the end of the study, approximately 4 weeks)
- VAS(At 4 weeks after baseline)
