简要总结
A reduction of intrinsic foot muscle sizes has been identified in patients with chronic plantar fasciitis. Weaker intrinsic foot muscles has been suggested to decrease the medial longitudinal arch height and subsequently increase extra tensile stress in the plantar fascia, resulting in the chronicity of the condition. Therefore, it is speculated that atrophic intrinsic foot muscles may be a significant risk factor of developing chronic plantar fasciitis. The purpose of this study is to investigate the effect of an 8-week targeted intrinsic foot muscles exercise regimen on the intrinsic foot muscle size, symptomatic relief, and foot function improvement in long-distance runners with chronic plantar fasciitis.
详细描述
Distance runners are defined as running with more than 20km per week for more than 2 years. All recruited participants have > 1 year of plantar fasciitis. The diagnosis were made based on clinical symptoms and the thickness of plantar fasciitis > 4.0mm at the medial tubercle of heel by ultrasound imaging.
Arm 1: The purpose of this arm of the study is to determine if a 8-week targeted foot muscle exercise regimen, instructed with real-time ultrasound, affect the intrinsic foot muscle size, symptomatic relief, and foot function improvement of distance runners with plantar fasciitis. 32 participants will be recruited in this arm.
Arm 2: This group will not engage in any training, but will serve as a comparator for the intervention arm.

结局指标
主要结局
cross sectional area (CSA) of Abductor Hallucis (AbH), Flexor hallucis brevis (FHB), Flexor digitorum brevis (FDB), quadratus plantae (QP)
时间窗: week 12
ultrasound measurement
muscle thickness (MT) of Abductor Hallucis (AbH), Flexor hallucis brevis (FHB), Flexor digitorum brevis (FDB), quadratus plantae (QP)
时间窗: week 12
ultrasound measurement
Visual Analog Scale (VAS) pain at first steps in the morning
时间窗: week 12
measuring 100 mm in length marked from 0 (absence of pain) to 100 mm (worst imaginable pain)
Navicular Drop test
时间窗: week 12
Supinated foot (\<5mm); Neutral foot (5-9mm); pronated foot (\>9mm)
Visual Analog Scale (VAS) worst pain of the day
时间窗: 12
measuring 100 mm in length marked from 0 (absence of pain) to 100 mm (worst imaginable pain)
Foot and Ankle Ability Measure (FAAM)
时间窗: week 12
Higher scores represent higher levels of function, with 100% representing no dysfunction.
Foot posture index
时间窗: week 12
Pronated postures are given a positive value, the higher the value the more pronated. Supinated features are given a negative value, the more negative the value the more supinated. For a neutral foot the final score should lie somewhere around zero
次要结局
- Postural control(week 12)
