BACKGROUND To date, no direct measurement has been done that quantitatively characterizes the foot-ground contact during Tai Chi Chuan movements. The goal of this study was to quantify the biomechanical characteristics of foot-ground contact during a Tai Chi gait (TCG), one of the basic but common Tai Chi Chuan movements. METHODS The ground reaction force profiles, center of pressure (COP) an...

BACKGROUND Custom foot orthoses are commonly recommended for the treatment of foot pain. OBJECTIVES To evaluate the effectiveness of custom foot orthoses for different types of foot pain. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2), MEDLINE (from January 1966), EMBASE (from January 1980), CINAHL (from January ...

Background: Patients with diabetic foot ulcer (DFU) usually have a poor quality of life (QoL) and self-efficacy, which is affected by many risk factors. However, the role psychological resilience in QoL self-efficacy DFU patients has remained unclear.

BACKGROUND Foot and ankle structures are the most commonly affected in people with gout. However, the effect of gout on foot and ankle muscle strength is not well understood. The primary aim of this study was to determine whether differences exist in foot and ankle muscle strength for plantarflexion, dorsiflexion, inversion and eversion between people with gout and age- and sex-matched controls...

BACKGROUND In stroke and multiple sclerosis patients, gait is frequently hampered by a reduced ability to push-off with the ankle caused by weakness of the plantar-flexor muscles. To enhance ankle push-off and to decrease the high energy cost of walking, spring-like carbon-composite Ankle Foot Orthoses are frequently prescribed. However, it is unknown what Ankle Foot Orthoses stiffness should b...

Background Foot morphology has received increasing attention from both biomechanics researches and footwear manufacturers. Usually, the morphology of the foot is quantified by 2D footprints. However, footprint quantification ignores the foot's vertical dimension and hence, does not allow accurate quantification of complex 3D foot shape. Methods The shape variation of healthy 3D feet in a popu...

Background: In many human postural studies, the foot is considered to be a rigid body. The human foot is composed of the arch structure, which is characteristic in every person and deforms with aging. Foot arch structure is assumed to effect postural control; however, underlying mechanisms remain unclear. The aim of this study was to elucidate the relationship between the structure of the foot ...

BACKGROUND Although foot problems are common in rheumatoid arthritis (RA), the consequences of foot problems from the patient perspective have not been fully explored. The aims of this study were to explore the experience of foot problems and decisions to access foot care services or not in patients with RA. METHODS Semi structured, one-to-one interviews with patients recruited from 2 UK rheu...
