In Achilles tendinopathy (AT) the ability to store and recycle elastic energy during ground contact phase is often altered. A measure of this function is represented by leg stiffness (LS). Immediate responses in LS following therapeutic intervention have not been examined.
The aim of this paper was to examine the feasibility of the protocol in participants with AT.
Single cohort feasibility study.
Adults with persistent AT pain, symptoms on palpation and less than 80 points on the Visa-A questionnaire.
heavy isometric exercise sequence in plantarflexion.
Feasibility was assessed by evaluating: the willingness of participants to enroll into the study, the number of eligible participants, the recruitment rate, adherence to the intervention, the drop-out rate, the tolerability of the protocol. LS, reactive strength index, pain and rate of perceived effort were secondary outcomes.
22 AT were eligible for data collection and 19 entered the statistical analysis. The intervention was well tolerated, no withdrawals. Pain scores were low during both the intervention and the assessment. Immediate improvements in LS and pain were recorded.
The isometric exercise protocol was feasible. Future research should investigate its effectiveness.
跟腱病（AT）患者在着地阶段储存和再循环弹性能的能力常常发生改变。衡量这一功能的指标是腿部刚度（LS）。治疗干预后 LS 的即时反应尚未被检测到。
本文旨在检查该方案在 AT 患者中的可行性。
单队列可行性研究。
持续存在 AT 疼痛、触诊时有症状且 Visa-A 问卷得分低于 80 分的成年人。
跖屈处的负重等长运动序列。
通过评估以下方面来评估可行性：参与者参加研究的意愿、合格参与者的数量、招募率、对干预的依从性、脱落率、方案的耐受性。LS、反应强度指数、疼痛和感知努力率是次要结局。
22 例 AT 符合数据收集条件，19 例进入统计分析。干预措施耐受性良好，无退出者。在干预和评估期间，疼痛评分均较低。记录到 LS 和疼痛的即刻改善。
等长运动方案是可行的。未来的研究应探讨其有效性。
