干针 vs 体外冲击波治疗在肱骨外上髁炎中的应用

实验性的：超声引导下干针疗法

参与者将接受超声引导下的干针治疗，针对总伸肌腱，每周一次，共五疗程。 所有参与者还将执行标准化的家庭锻炼计划。

程序：超声引导下干针治疗

干针治疗将在超声引导下进行，针对伸肌腱总腱的腱病区域。该操作将每周进行一次，共五次。

有源比较器：体外冲击波疗法

参与者将每周一次接受应用于外上髁的放射状体外冲击波治疗，总共五次疗程。 所有参与者还将执行标准化的家庭锻炼计划。

设备：体外冲击波疗法

利用标准参数（10-15 Hz，1.5-2.5 bar，2000 次脉冲）每五周进行一次体外冲击波治疗。

Change in pain intensity measured by Visual Analog Scale (VAS)

Pain intensity will be assessed using a 10-cm visual analog scale. Change from baseline to immediate post-treatment, upto 3 months, and upto 6 months will be analyzed. The Visual Analogue Scale (VAS) was used to assess the severity of elbow pain during activity. Scores range from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain severity and therefore a worse outcome.

握力变化

使用手部测力计以千克为单位测量握力。

压力疼痛阈值的变化

将使用手持式痛觉测量仪在外上髁处测量压力痛阈值。

超声肌腱厚度的变化

将使用肌肉骨骼超声测量常见的伸肌腱厚度。

Change in Patient-Rated Tennis Elbow Evaluation (PRTEE) score

PRTEE questionnaire will be used to evaluate pain and functional disability in lateral epicondylitis. The Patient-Rated Tennis Elbow Evaluation (PRTEE) is a 15-item, elbow-specific questionnaire assessing pain and functional disability. It comprises a Pain subscale (5 items; score range, 0-50) and a Function subscale (10 items; converted score range, 0-50). The total PRTEE score ranges from 0 to 100, where 0 indicates no pain or functional disability and 100 indicates the greatest possible pain and disability. Higher scores indicate a worse outcome.

Change in quality of life measured by SF-12

Quality of life will be assessed using the Short Form-12 questionnaire. The 12-Item Short Form Health Survey (SF-12) was used to assess health-related quality of life. It generates two separate summary scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). Each component score ranges from 0 to 100, where 0 represents the worst health status and 100 represents the best health status. Higher scores indicate better physical or mental health and therefore a better outcome. The PCS and MCS scores were evaluated separately; no overall SF-12 total score was calculated.

Change in Power Doppler neovascularization score

Neovascularization will be evaluated using semi-quantitative Power Doppler scoring. The Color Doppler Ultrasound Neovascularization Score was used to grade vascular activity within the common extensor tendon. Scores range from 0 to 4: grade 0 indicates no Doppler activity; grade 1 indicates a single vessel; grade 2 indicates Doppler activity occupying less than 25% of the region of interest; grade 3 indicates activity occupying 25%-50% of the region of interest; and grade 4 indicates activity occupying more than 50% of the region of interest. Higher scores indicate greater neovascularization and a worse ultrasonographic tendon outcome.
