STUDY DESIGN A 2 x 4 mixed-design ANOVA with a fixed factor of group (posterior tibialis tendon dysfunction [PTTD] and asymptomatic controls), and a repeated factor of phase of stance (loading response, midstance, terminal stance, and preswing). OBJECTIVE To compare 3-dimensional stance period kinematics (rearfoot eversion/inversion, medial longitudinal(More)
The lack of a common reference position when defining foot postures may underestimate the ability to differentiate foot function in subjects with pathology. The effect of using the subtalar neutral (STN) position as an offset for both rearfoot and forefoot through comparison of the kinematic walking patterns of subjects classified as normal (n=7) and(More)
OBJECTIVE To assess the effect of a 4-week intervention with a full-length carbon graphite (FL) orthosis on pain and function in patients with midfoot arthritis, and to identify alterations in in vivo foot kinematics accompanying FL use in patients with midfoot arthritis. These results have immediate application for enhancing patient care through effective(More)
STUDY DESIGN Experimental laboratory study using a cross-sectional design. OBJECTIVES To compare foot kinematics, using 3-dimensional tracking methods, during a bilateral heel rise between participants with posterior tibial tendon dysfunction (PTTD) and participants with a normal medial longitudinal arch (MLA). BACKGROUND The bilateral heel rise test is(More)
STUDY DESIGN Case control study. OBJECTIVE To compare posterior tibialis (PT) length between subjects with stage II posterior tibial tendon dysfunction (PTTD) and healthy controls during the stance phase of gait. BACKGROUND The abnormal kinematics demonstrated by subjects with stage II PTTD are presumed to be associated with a lengthened PT(More)
BACKGROUND Subjects with stage II posterior tibial tendon dysfunction (PTTD) exhibit abnormal foot kinematics; however, how individual segment kinematics (hindfoot (HF) or first metatarsal (first MET) segments) influence global foot kinematics is unclear. The purpose of this study was to compare foot and ankle kinematics and sagittal plane HF and first MET(More)
The purpose of this study was to compare in vivo segmental foot motion during walking and step descent in patients with midfoot arthritis and asymptomatic control subjects. Segmental foot motion during walking and step descent was assessed using a multi-segment foot model in 30 patients with midfoot arthritis and 20 age, gender and BMI matched controls.(More)
The purpose of this study was to compare in-vivo kinematic angular excursions of individual metatarsal segments and a unified forefoot segment in people with Diabetes Mellitus and peripheral neuropathy (DMPN) without deformity or ulceration to a healthy matched control group. Thirty subjects were recruited. A five- segment foot model (1st, 3rd, and 5th(More)
Neuropathic tissue changes can alter muscle function and are a primary reason for foot pathologies in people with Diabetes Mellitus and peripheral neuropathy (DMPN). Understanding of foot kinetics in people with DMPN is derived from single-segment foot modeling approaches. This approach, however, does not provide insight into midfoot power and work. Gaining(More)
Introduction Patients with midfoot arthritis present with disabling pain, which limits their participation in walking and other physical activity. The primary aim of treatment is to afford pain relief and is often attempted using shoe inserts. The custom-molded three-quarter insert (3Q) is recommended as the first line of treatment; however clinical(More)
