BACKGROUND: Kinematic analysis could help to study how variations in the static foot posture affect lower limb biomechanical function. The analysis of foot kinematics is complex because it involves managing the time-dependent joint angles in different joints and in all three planes of motion. But it could be simplified if joint angles are coordinated. METHODS: The kinematics of the ankle, midtarsal and metatarsophalangeal joints were registered in 20 highly-pronated, 30 normal and 20 highly-supinated subjects (assessed by the Foot Posture Index - FPI) as they walked barefoot...

BACKGROUND: With improved survival rates in pediatric oncology, the detection of adverse side- and late-effects is gaining increased interest. This cross-sectional study investigated walking abilities and ankle dorsiflexion function in children with cancer. PATIENTS: Study participants included 16 children with various cancers (4-20 years, patient group) after completion of the intense treatment and 16 age- and gender-matched healthy peers (comparison group). METHOD: Walking speed (10-meter-walking-test, treadmill test assessing preferred transition speed), walking capacity (2-minute-walk-test), walking balance (Timed-Up-And-Go-Test), active/passive ankle dorsiflexion range of motion (ROM) (goniometer) and ankle dorsiflexion strength (hand-held dynamometer) were comprehensively assessed...

CASE: Congenital vertical talus (CVT) is a rare rigid flatfoot disorder with a rocker-bottom flatfoot appearance. It is characterized by hindfoot valgus and equinus, with associated midfoot dorsiflexion and forefoot abduction. We describe a patient who was born with dysmorphic features and subsequently was diagnosed with Beals contractural arachnodactyly. After the diagnosis of bilateral CVT was made, it was treated with a single-stage open reduction. There was a unilateral recurrence, which was treated with revision surgery...

CONTEXT: Kinesiology tape (KT), multidirectional resistance exercise, and interventions for decreased ankle dorsiflexion range of motion (ROM) are gaining popularity in the treatment of patients with chronic ankle instability (CAI). However, there is limited evidence of the effectiveness of combined interventions in CAI patients. OBJECTIVES: To compare the effects of KT alone, KT with resistance exercise (KT + resistance), and KT + resistance + heel raise-lower exercise (KT + resistance + heel) on the results of the dynamic balance test (star excursion balance test [SEBT]), functional performance (lateral step-down test), and ankle muscle activation in CAI patients...

Mechanical tuning of an ankle-foot orthosis (AFO) is important in improving gait in individuals post-stroke. Alignment and resistance are two factors that are tunable in articulated AFOs. The aim of this study was to investigate the effects of changing AFO ankle alignment on lower limb joint kinematics and kinetics with constant dorsiflexion and plantarflexion resistance in individuals post-stroke. Gait analysis was performed on 10 individuals post-stroke under four distinct alignment conditions using an articulated AFO with an ankle joint whose alignment is adjustable in the sagittal plane...

Kinesthesia, the perception of our own body movements, relies on the integration of proprioceptive information arising mostly from muscle spindles, which are sensory receptors in skeletal muscles. We recently showed that emotions alter the proprioceptive messages from such muscle afferents, making them more sensitive to muscle lengthening when participants were listening sad music. Presently, we investigated whether these changes in proprioceptive feedback relating to emotional state may affect the perception of limb movements...

BACKGROUND: For demanding activities in daily life, such as negotiating stairs, ramps and uneven ground, the functionality of conventional prosthetic feet ("Daily Life Feet" - DLF) is often limited. With the introduction of microprocessor-controlled feet (MPF) it was expected that the functional limitations of DLF might be reduced. The purpose of the present study was to investigate biomechanical gait parameters with DLF and MPF when walking on a specifically designed ramp involving abruptly changing inclination angles as a scenario reflecting typical situations related to walking on uneven ground...

Background: Medial tibial stress syndrome (MTSS) is a lower leg injury with a reported incidence rate of up to 35% in active individuals. Although numerous prospective studies have tried to identify risk factors for developing MTSS, managing the syndrome remains difficult. One risk factor yet to be extensively explored in MTSS development is reduced lower leg girth. Further investigation of reduced lower leg girth is required due to the important role lower leg musculature plays in attenuating ground reaction forces during the gait cycle...

While an important step in a young dancer's ballet career is the transition to pointe work, there is much controversy as to when her body is physically prepared to meet the increased demands of this development. Pointe screening protocols are being used by many in both the dance studio and dance science communities, but these protocols have not yet been standardized. The purpose of this study was to evaluate objectively the attributes of ballet dancers who are pre-pointe compared to those who have recently begun pointe training, and secondarily to correlate these quantitative findings with qualitative evaluations by the dancers' teachers...

BACKGROUND: Patients with stroke generally have diminished balance and gait. Mobilization with movement (MWM) can be used with manual force applied by a therapist to enhance talus gliding movement. Furthermore, the weight-bearing position during the lunge may enhance the stretch force. OBJECTIVES: This study aimed to compare the effects of a 4-week program of MWM training with those of static muscle stretching (SMS). Ankle dorsiflexion passive range of motion (DF-PROM), static balance ability (SBA), the Berg balance scale (BBS), and gait parameters (gait speed and cadence) were measured in patients with chronic stroke...
