Abstract：
OBJECTIVE: To determine the relationships between (1) Achilles tendon pain and loading symmetry, and (2) number of running bouts and symptom severity, during two weeks of outdoor running in individuals with Achilles tendinopathy.
METHODS: Prospective, observational study.
METHODS: Biomechanics laboratory and outdoors.
METHODS: Seventeen runners with Achilles tendinopathy in the return-to-sport phase of rehabilitation.
METHODS: Symptom severity was recorded with the Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire. Running bouts and Achilles tendon pain during runs were recorded with daily training logs. Ground contact time was collected during runs with wearable sensors. Linear mixed modeling determined if the relationship between Achilles tendon pain and ground contact time symmetry during running was moderated by consecutive run days. Multiple regression determined the relationship between number of running bouts and change in VISA-A scores over two weeks, adjusted for run distance.
RESULTS: Greater ground contact time on the contralateral leg corresponded to increased ipsilateral tendon pain for each consecutive run day (b = -0.028, p < 0.001). Number of running bouts was not associated with 2-week changes in VISA-A scores (p = 0.672).
CONCLUSIONS: Pain during running is associated with injured leg off-loading patterns, and this relationship strengthened with greater number of consecutive run days. Number of running bouts was not related to short-term symptom severity.

摘要：
目的：确定（1）跟腱疼痛与负荷对称性之间的关系，以及（2）跑步次数和症状严重程度，在跟腱病患者进行为期两周的户外运动期间。
方法：前瞻性，观察性研究。
方法：生物力学实验室和室外。
方法：17名患有跟腱病的跑步者处于康复恢复运动阶段。
方法：使用维多利亚运动协会跟腱评估（VISA-A）问卷记录症状严重程度。用每日训练日志记录跑步发作和跑步过程中的跟腱疼痛。使用可穿戴传感器在运行期间收集地面接触时间。线性混合模型确定了跑步过程中跟腱疼痛与地面接触时间对称性之间的关系是否通过连续的跑步天数来调节。多元回归确定了两周内跑步次数与VISA-A分数变化之间的关系，调整运行距离。
结果：对侧腿的地面接触时间增加对应于每个连续运行日的同侧肌腱疼痛增加（b=-0.028，p<0.001）。跑步次数与VISA-A评分的2周变化无关（p=0.672）。
结论：跑步过程中的疼痛与腿部受伤的卸载模式有关，随着连续运行天数的增加，这种关系得到了加强。跑步次数与短期症状严重程度无关。
