This study aimed at investigating the effectiveness of an 8-week training protocol, based on neuromuscular electrical stimulation of the quadriceps, which was superimposed onto voluntary exercise (NMES+), in comparison to a traditional heavy slow resistance training (HSRT), in individuals with patellar tendinopathy.
Thirty-two physically active participants, aged: 33.6±10.2 years, were divided into two groups: NMES+ or HSRT. Maximal voluntary isometric contraction (MVIC) of knee extensor and flexor muscles, power during a countermovement jump (CMJ), and VISA-p questionnaire scores were recorded at the start(T0), 2-weeks(T1), 4-weeks(T2), 6-weeks(T3), 8-weeks(T4) and 4-months post-training (T5). Knee pain and rate of perceived exertion (RPE) were recorded at each training session with a 0-10 scale.
Knee pain was significantly lower in NMES+ compared to HSRT during all training sessions. No significant between-group differences were found for VISA-p scores and forces recorded during MVICs at T0,T1,T2,T3,T4 and T5. A significant increase of VISA-p and peak forces during MVIC was recorded across-time in both groups. No significant between-group or across-time differences were found for RPE and CMJ parameters.
NMES+ and HSRT were equally effective in decreasing tendinopathy symptoms and increasing strength, with NMES+ having the advantage to be a pain-free resistance training modality.
本研究旨在比较基于股四头肌神经肌肉电刺激的 8 周训练方案（NMES+）与传统的重阻力慢训练（HSRT）对髌腱病患者的疗效。
32 名活跃的参与者，年龄：33.6±10.2 岁，被分为两组：NMES+或 HSRT。在开始（T0）、2 周（T1）、4 周（T2）、6 周（T3）、8 周（T4）和训练后 4 个月（T5）时记录膝关节伸肌和屈肌的最大等长收缩（MVIC）、反跳跳（CMJ）时的功率以及 VISA-p 问卷评分。在每次训练时，用 0-10 分制记录膝关节疼痛和感觉用力程度（RPE）。
NMES+组在所有训练时的膝关节疼痛均明显低于 HSRT 组。在 T0、T1、T2、T3、T4 和 T5 时，MVIC 记录的 VISA-p 评分和力无组间差异。两组的 VISA-p 和 MVIC 峰值力均随时间显著增加。RPE 和 CMJ 无组间或随时间的差异。
NMES+和 HSRT 均可有效减轻腱病症状和增加力量，NMES+的优势在于它是一种无痛的抗阻训练方式。
