Variable Lower Limb Alignment of Clinical Measures With Digital Photographs and the Footscan Pressure System

Figen Govsa, Gkionoul Nteli Chatzioglou, Simin Hepguler, Yelda Pinar, and Ozden Bedre

The human foot complex is a multijoint mechanism that determines the critical interaction between the lower limb and the ground during locomotion. 1 – 3 Any injury, lesion, or neuromuscular disorder of this key element of the lower limb drastically affects the normal interaction between muscles

The Effectiveness of Low-Dye Taping in Reducing Pain Associated With Plantar Fasciitis

Laura A. Verbruggen, Melissa M. Thompson, and Chris J. Durall

Clinical Scenario Plantar fasciitis is one of the most common musculoskeletal disorders of the foot. 1 – 5 Initial treatment of plantar fasciitis is typically conservative and may include heel padding, steroid injections, night splinting, calf-stretching, ultrasound, foot orthoses, and taping

Direction of Foot Force for Pushes against a Fixed Pedal: Role of Effort Level

Kreg G. Gruben, Lynn M. Rogers, and Matthew W. Schmidt

Control of the force exerted by the foot on the ground is critical to human locomotion. During running on a treadmill and pushing against a fixed pedal, humans increased foot force in a linear manner in sagittal plane force space. However, for pushes against a moving pedal, force output was linear for some participants but slightly curved for others. A primary difference between the static and dynamic pedaling studies was that the dynamic study required participants to push with varying peak effort levels, whereas a constant peak effort level was used for the fixed pedal pushes. The present study evaluated the possibility that force direction varied with level of effort. Seated humans pushed against a fixed pedal to a series of force magnitude targets. The force direction varied systematically with effort level consistent with the force path curvature observed for dynamic pedaling.

Relationships Between Arch Height Flexibility and Medial–Lateral Ground Reaction Forces in Rearfoot and Forefoot Strike Runners

Caleb D. Johnson and Irene S. Davis

The relationship between measures of foot arch function and musculoskeletal injuries in recreational runners and military personnel has been reported in several previous studies. 1 – 6 Much of this work has focused on the height of the medial longitudinal arch, often characterized by the arch

Association of Proximal and Distal Factors With Lower Limb Kinematics During a Classical Ballet Jump

ballet dancers. 7 Proximal (hip) and distal (ankle–foot complex) factors may contribute to impaired dynamic lower limb kinematics. 17 Proximally, an excessive movement of hip adduction may increase dynamic lower limb valgus during weight-bearing activities, 17 and it may occur as a consequence of hip

Obesity is Associated With Altered Plantar Pressure Distribution in Older Women

Silvia Gonçalves Ricci Neri, André Bonadias Gadelha, Ana Luiza Matias Correia, Juscélia Cristina Pereira, Ana Cristina de David, and Ricardo M. Lima

Gait abnormalities have been consistently related to falls. 6 During ambulation, the foot is the only source of direct contact with the ground. Therefore, any factor that might disrupt normal foot function is likely to impair postural stability and, as a consequence, increase the risk of falls

Effectiveness of Dry Cupping as a Treatment for Plantar Fasciitis: A Critically Appraised Topic

Philip A. Szlosek and Matthew Campbell

Alkhadhrawi and Alshami 4 used stretching of the gastroc–soleus complex and plantar fascia, and Malik et al 2 incorporated intrinsic foot muscle strengthening and cryo-therapy in addition to stretching of the gastroc–soleuss complex and plantar fascia. In contrast, Ge et

Effects of Vertical Loading on Arch Characteristics and Intersegmental Foot Motions

Douglas W. Powell, Benjamin Long, Clare E. Milner, and Songning Zhang

The medial longitudinal arch plays a major role in determining lower extremity kinematics. Thus, it is necessary to understand the dynamics of the arch structure in response to load. The purpose of this study was to examine arch function in high- and low-arched feet during a vertical loading condition. Ten high- and ten low-arched females performed five trials in a sit-to-stand exercise. Ground reaction force (1200 Hz) and three-dimensional kinematics (240 Hz) were collected simultaneously. The high-and low-arched athletes had no differences in vertical deformation of the arch. High-arched participants were less everted than the low-arched athletes; furthermore, the high-arched athletes had smaller mid-forefoot eversion excursions. Differences between the high-arched and low-arched athletes occur through and motion at the mid-forefoot joint.

Effects of Short-Foot Exercises on Foot Posture, Pain, Disability, and Plantar Pressure in Pes Planus

-bearing activities. Pes planus causes impaired plantar load distribution, excessive stress in the foot, ankle, and knee joints, and compensatory internal rotation of the hip joint. Common lower-limb pathologies such as hallux valgus, plantar fasciitis, tibialis posterior dysfunction, tarsal tunnel syndrome, and
