To investigate the differences in biomechanical parameters measured by gait analysis systems between healthy subjects and subjects with plantar fasciitis (PF), and to compare biomechanical parameters between 'normal, barefooted' gait and arch building gait in the participants.
The researchers evaluated 15 subjects (30 feet) with bilateral foot pain and 15 subjects (15 feet) with unilateral foot pain who had a clinical diagnosis of PF. Additionally, 17 subjects (34 feet) who had no heel pain were recruited. Subjects were excluded if they had a traumatic event, prior surgery or fractures of the lower limbs, a leg length discrepancy of 1 cm or greater, a body mass index greater than 35 kg/m, or had musculoskeletal disorders. The participants were asked to walk with an arch building gait on a treadmill at 2.3 km/hr for 5 minutes. Various gait parameters were measured.
With the arch building gait, the PF group proved that gait line length and single support line were significantly decreased, and lateral symmetry of the PF group was increased compared to that of the control group. The subjects with bilateral PF displayed significantly increased maximum pressure over the heel and the forefoot during arch building gait. In addition, the subjects with unilateral PF showed significantly increased maximum pressure over the forefoot with arch building gait.
The researchers show that various biomechanical differences exist between healthy subjects and those with PF. Employing an arch building gait in patients with PF could be helpful in changing gait patterns to normal biomechanics.
研究健康受试者与足底筋膜炎（PF）患者在步态分析系统测量的生物力学参数上的差异，并比较参与者“正常、赤足”步态与足弓构建步态之间的生物力学参数。
研究人员评估了15名双侧足部疼痛的受试者（30只脚）和15名单侧足部疼痛且临床诊断为PF的受试者（15只脚）。此外，招募了17名无足跟疼痛的受试者（34只脚）。如果受试者有创伤事件、既往手术史或下肢骨折、腿长差异1厘米或更大、体重指数大于35kg/m²或有肌肉骨骼疾病，则将其排除。参与者被要求在跑步机上以2.3公里/小时的速度采用足弓构建步态行走5分钟。测量了各种步态参数。
采用足弓构建步态时，PF组的步态线长度和单支撑线明显缩短，且与对照组相比，PF组的侧向对称性增加。双侧PF受试者在足弓构建步态期间足跟和前足的最大压力显著增加。此外，单侧PF受试者在足弓构建步态时前足的最大压力显著增加。
研究人员表明，健康受试者与PF患者之间存在各种生物力学差异。PF患者采用足弓构建步态可能有助于将步态模式转变为正常生物力学。
