Assessment of myofascial tissue stiffness have a role in identifying physical impairments in plantar fasciopathy (PF). It is still unclear which specific functional and tissue differences exist between individuals with PF.
To compare myofascial stiffness of plantar fascia, Achilles tendon, and triceps surae between symptomatic and asymptomatic limbs in individuals with PF and between individuals with and without PF.
Thirty nine individuals diagnosed with PF and individuals with no history of PF were recruited. Myofascial stiffness of the plantar fascia, Achilles tendon, and triceps surae, range of motion, and clinical tests were performed. Mean difference (MD) and 95% confidence interval (CI) were calculated.
Individuals with PF showed lower mean stiffness in Achilles tendon insertion (MD = -1.00 N/mm; 95%CI: -1.80,-0.21) on the symptomatic limb compared to the corresponding symptomatic limb in control group, a lower mean stiffness in plantar fascia (MD = -0.16 N/mm; 95%CI: -0.30, -0.01) on the symptomatic limb compared to asymptomatic limb, and a lower mean stiffness in the region 3 cm above the Achilles tendon insertion (MD = -0.79; 95%CI: -1.59, -0.00) compared to control. Individuals with PF showed fewer repetitions in heel rise test (MD = -3.97 reps; 95%CI: -5.83, -2.12) and in the step-down test (MD = -5.23 reps; 95%CI: -7.02, -3.44) compared to control.
Individuals with PF present reduced stiffness in Achilles tendon insertion and plantar fascia. The reduced stiffness was more evident in Achilles tendon in individuals with PF compared to individuals without PF. Individuals with PF showed lower performance in clinical tests.
评估筋膜组织的僵硬程度在确定足底筋膜炎（PF）的身体损伤方面发挥作用。目前尚不清楚 PF 患者的个体之间存在哪些特定的功能和组织差异。
比较 PF 患者症状侧和无症状侧、PF 患者与无 PF 患者之间足底筋膜、跟腱和小腿三头肌的筋膜僵硬程度。
招募了 39 名被诊断为 PF 的患者和没有 PF 病史的患者。对足底筋膜、跟腱和小腿三头肌的筋膜僵硬程度、活动范围和临床检查进行了评估。计算了平均值差异（MD）和 95%置信区间（CI）。
与对照组相比，PF 患者的症状侧跟腱附着处的平均僵硬程度较低（MD=-1.00N/mm；95%CI：-1.80，-0.21），症状侧的足底筋膜平均僵硬程度也较低（MD=-0.16N/mm；95%CI：-0.30，-0.01），跟腱附着处上方 3cm 处的平均僵硬程度也较低（MD=-0.79；95%CI：-1.59，-0.00）。与对照组相比，PF 患者的足跟抬高试验重复次数较少（MD=-3.97 次；95%CI：-5.83，-2.12），台阶下降试验重复次数也较少（MD=-5.23 次；95%CI：-7.02，-3.44）。
PF 患者的跟腱附着处和足底筋膜僵硬程度降低。PF 患者的跟腱僵硬程度比无 PF 患者更为明显。PF 患者的临床检查表现较差。
