We set out to assess whether quantitative ultrasound could be used to assess changes that occur after physical therapy in patients experiencing myofascial pain syndrome.
We consecutively recruited female subjects experiencing myofascial pain syndrome of the neck and shoulder region and provided 10 sessions of conservative physical therapy. A control group was recruited for textural analyses. We measured change in pain ratings, range of motion, and ultrasound texture features before and after the intervention and after 3 mos.
We recruited 63 female myofascial pain syndrome subjects and 20 healthy controls. After treatment, the mean blob size (an ultrasound texture feature) value for each subject decreased from 30.84 ± 5.00 to 25.86 ± 5.67 on the right and decreased from 31.70 ± 5.51 to 28.08 ± 5.53 on the left (P < 0.0005). The blob count showed a significant increase only on the left side (P < 0.01). Corresponding to this were reductions in pain and disability scores after treatment and at 3 mos compared with retreatment (P < 0.0005 for all checkpoints). Cervical range of motion values were significantly increased only at 3 mos compared with pretreatment except for mean flexion range of motion.
Ultrasound texture feature of blob size and count changes correspond to routine clinical outcomes after conservative physical therapy of myofascial pain syndrome in female individuals.
我们旨在评估定量超声是否可用于评估肌筋膜疼痛综合征患者接受物理治疗后的变化。
我们连续招募了患有颈肩部肌筋膜疼痛综合征的女性受试者，并提供了 10 次保守性物理治疗。招募了对照组进行纹理分析。我们在干预前后以及 3 个月后测量了疼痛评分、活动范围和超声纹理特征的变化。
我们招募了 63 名女性肌筋膜疼痛综合征患者和 20 名健康对照者。治疗后，每位患者右侧的平均斑点大小（一种超声纹理特征）值从 30.84 ± 5.00 降至 25.86 ± 5.67，左侧从 31.70 ± 5.51 降至 28.08 ± 5.53（P < 0.0005）。斑点计数仅在左侧显著增加（P < 0.01）。相应地，与再治疗相比，治疗后和 3 个月时疼痛和残疾评分均降低（所有检查点 P < 0.0005）。除了平均前屈范围外，只有在 3 个月时颈椎活动范围才显著增加，与治疗前相比。
在女性肌筋膜疼痛综合征的保守性物理治疗后，斑点大小和计数的超声纹理特征变化与常规临床结局相对应。
