简要总结
The purpose of this study was to determine the effectiveness of two types of in-shoe custom made orthotics in altering the motion of the foot and muscle activity of select muscles of the lower leg in individuals experiencing lower extremity symptoms of a non traumatic origin. We hypothesized that orthotics would decrease the extent of motion of the during walking and running when compared to a barefoot condition. The investigators further hypothesized that orthotics would decrease the amount of muscle activity seen during walking and running when compared to barefoot walking.

入选标准
- •Subjects must have complaints of lower extremity or foot pain of a non-traumatic, mechanical origin.
- •Subjects must have at least 60 degrees of frontal plane forefoot on rearfoot passive range of motion (as determined by a modified Gib test in the symptomatic lower extremity.
- •Subjects must be able to walk independently on a treadmill at a speed of 4.8 kmh.
- •Subjects must have been referred by a health care professional for an orthosis fitting.
排除标准
- •Subjects having less than 60 degrees of forefoot on rearfoot frontal plane passive range of motion.
- •Subjects having a history of a fracture of the foot or ankle.
- •Subjects having any previous illness, surgery or other characteristic (e.g., cardiovascular, musculoskeletal or neuromuscular problems) that would affect their lower extremity function or ability to walk independently.
- •Subjects having knee, lower leg or foot pain of a non-mechanical nature.
结局指标
主要结局
Maximum Rearfoot Eversion Motion During Stance
时间窗: Absolute values measured at 5 weeks
The rearfoot eversion motion during the stance phase of walking with the subject wearing a sandal and their assigned orthotic (Full Contact or Maximal Arch Subtalar Stabilization) was recorded 5 weeks post receiving their assigned orthotic. The stance phase of walking was divided into 4 subphases (Phase 1: 0 to 17%, Phase 2: 18 to 50%, Phase 3: 51 to 83%, and Phase 3: 84 to 100% of stance) and the maximum rearfoot eversion during each subphase determined.
次要结局
- Maximum Electromyographic Activity of Lower Leg Muscles(Absolute values measured at 5 weeks)
- Maximum Forefoot Inversion During Stance(Absolute values measured at 5 weeks)
- Maximum First Ray Complex Plantarflexion During Stance(Absolute values measured at 5 weeks)
