Objectives

To determine the additional effect of dry needling (DN) or percutaneous needle electrolysis (PNE) combined with eccentric exercise (EE) and determine which is the most effective for patients with patellar tendinopathy (PT).

Design

Blinded, randomized controlled trial, with follow-up at 10 and 22 weeks.

Settings

Recruitment was performed in sport clubs. Diagnosis and intervention were conducted at San Jorge University.

Participants

Patients (N=48) with PT with pain for at least 3 months between the ages of 18 and 45 years.

Interventions

Three interventions were carried out: DN and EE, PNE and EE, and EE with sham needle as the control group.

Main Outcome Measures

Disability was measured using the Victorian Institute of Sports Assessment Questionnaire, patellar tendon. Visual analog scale was used to measure pain over time, the Short Form-36 was used to measure quality of life, and ultrasound was used to measure structural abnormalities.

Results

A total of 48 participants (42 men, 6 women; average age, 32.46y; SD, 7.14y) were enrolled. The improvement in disability and pain in each group between baseline and post-treatment and baseline and follow-up was significant (P≤.05), without differences among groups.

Conclusion

DN or PNE combined with an EE program has not shown to be more effective than a program of only EE to improve disability and pain in patients with PT in the short (10wk) and medium (22wk) terms. Clinical improvements were not associated with structural changes in the tendon.

Pat骨腱鞘病的治疗干预措施的比较研究：随机对照试验。

目标

确定干针刺（DN）或经皮针刺电解（PNE）结合离心运动（EE）的附加效果，并确定哪种方法对pa肌腱病（PT）最有效。

设计

盲法，随机对照试验，在10周和22周进行随访。

设定值

招聘是在体育俱乐部进行的。在圣豪尔赫大学进行了诊断和干预。

参加者

年龄在18至45岁之间的PT疼痛患者（N = 48）至少持续3个月。

干预措施

进行了三种干预：DN和EE，PNE和EE，以及以假针为对照组的EE。

主要观察指标

使用维多利亚州体育运动评估问卷，pa骨肌腱对残疾进行测量。视觉模拟量表用于测量一段时间内的疼痛，Short Form-36用于测量生活质量，超声用于测量结构异常。

结果

共有48位参与者（42位男性，6位女性；平均年龄为32.46岁； SD为7.14岁）参加了研究。基线和后处理和基线和随访之间的每个组中残疾和疼痛的改善是显著（P ≤.05），无组间差异。

结论

DN或PNE与EE计划相结合并没有显示出比仅EE计划在短期（10wk）和中度（22wk）方面改善PT患者的残疾和疼痛的方法更有效。临床改善与肌腱结构改变无关。
