简要总结
In this cross-over study 25 patients with chronic low back pain (CLBP) were tested for pain relief in 2 conditions: while using the Transcutaneous Electrical Nerve Stimulation (TENS) application and without using it. Primary outcome: Movement-Evoked Pain (MEP). This was measured using the Back Performance Scale (BPS) and a 5-minute walk test (5MWT). Participants performed 5 functional tasks and were asked to rate their pain before, during, and after each movement on a numeric rating score scale. The same principle will be used for the 5MWT: for each walking-minute, 3 pain measurements will be assessed.

入选标准
- •chronic nonspecific LBP for at least 3 months' duration: non-specific LBP implies that patients are not allowed to have any evidence of specific spinal pathology (e.g., hernia, spinal stenosis, spondylolisthesis, infection, spinal fracture or malignancy).
排除标准
- •spinal surgery in the past 6 months
- •severe underlying comorbidity (like diagnosed diabetes, cardiovascular problems, etc.),
- •pregnant or given birth in the preceding year,
- •having initiated a new LBP treatment in the 6 weeks prior to study participation
结局指标
主要结局
Movement Evoked Pain
时间窗: Change in pain score between (1) Movement Evoked Pain measures assessed without TENS application and (2) Movement-Evoked Pain measured assessed while using TENS application. Between both measures, a wash out period of 30 minutes was introduced.
Pain that is experienced in response to 2 physical tasks: the Back Performance Scale and the 5 minutes walk test. Participants performed 5 physical tasks (= 1) grasping toes with fingertips in a sitting position; 2) forward bending from standing; 3) picking up paper from standing; 4) long-sitting from supine and 5) lifting a 5kg box from floor to table) and walked for 5 minutes. Participants provided a pain rating on a 11 points Numeric Rating Scale (NRS) with the endpoints no pain" (0) and "excruciating pain" (10). Pain will be assessed during the physical tasks (=at the same moment).
