Fish, birds, and lizards sometimes perform locomotor activities with maximized muscle power. Whether humans maximize muscular power is unknown because current experimental techniques cannot be applied non-invasively. This study uses simulated muscle work loops to examine whether voluntary maximal cycling is characterized by maximized muscle power. The simulated work loops leverage experimentally measured joint angles, anatomically realistic muscle parameters (muscle-tendon lengths, velocities, and moment arms), and a published muscle model to calculate powers and forces for thirty-eight muscles...

BACKGROUND: Hamstring injuries remain a significant injury burden in sports such as soccer that involve high-speed running. It has repeatedly been identified as the most common noncontact injury in elite male soccer, representing 12% of all injuries. As the incidence of hamstring injuries remains high, investigations are aimed at better understanding how to prevent hamstring injuries. Stretching to improve flexibility is commonly used in elite-level sports, but risk factor studies have reported contradicting results, leading to unclear conclusions regarding flexibility as a risk factor for hamstring injuries...

BACKGROUND: Chronic plantar heel pain (CPHP) is a common condition with high prevalence rates and a projected cost of treatment of US$192 to US$376 million. There are several therapeutic approaches and there is increased interest in treatments aimed at the regeneration of tissues with poor healing potential. Our purpose was to investigate the effectiveness of ultrasound-guided percutaneous needle electrolysis in chronic plantar heel pain. METHODS: A total of 73 patients with a clinical and ultrasonographic diagnosis of plantar heel pain unrelated to systemic inflammatory disease who had not received any other treatment in the previous 6 months on the affected foot were randomly allocated to receive either ultrasound-guided percutaneous needle electrolysis of the fascia (experimental group, n = 39) or placebo puncture (control group, n = 34)...

BACKGROUND: Restoration of correct coronal alignment is one of the main goals of total knee arthroplasty (TKA). Traditionally, TKA has been considered successful when a neutral mechanical hip-knee-ankle (HKA) axis within 3° is achieved. Recent studies have reported no differences or improved clinical outcomes following a slight under-correction of the HKA axis for a varus knee. However, the influence of under-correction of a valgus knee has not been reported. This study investigated the influence of post-operative HKA alignment in TKA patients with valgus deformity on clinical outcomes...

Ballerinas use their ankle joints more extremely and sustain injuries on the ankle joint more frequently than non-dancers. Therefore, the ankle movement of dancers is important and should be studied to prevent injuries. Measuring ankle joint range of motion (ROM) using radiographs could demonstrate the contribution to motion of each joint. The aim of this study was to analyse and compare ankle joint movements and the ratio of each joint's contribution during movement between dancers and non-dancers, using radiographic images...

BACKGROUND: Achieving proper rotational alignment of the femoral component in total knee arthroplasty (TKA) for valgus knee is challenging because of lateral condylar hypoplasia and lateral cartilage erosion. Gap-based navigation-assisted TKA enables surgeons to determine the angle of femoral component rotation (FCR) based on the posterior condylar axis. This study evaluated the possible factors that affect the rotational alignment of the femoral component based on the posterior condylar axis...

Total knee arthroplasty is a common surgical treatment for end-stage osteoarthritis of the knee. The majority of existing studies that have explored the relationship between recovery and gait biomechanics have been conducted in laboratory settings. However, seamless gait parameter monitoring in real-world conditions may provide a better understanding of recovery post-surgery. The purpose of this study was to estimate kinematic and kinetic gait variables using two ankle-worn wearable sensors in individuals after unilateral total knee arthroplasty...

BACKGROUND: Preoperative ankle coronal malalignment has been considered as a risk factor for poor outcomes and failure after total ankle arthroplasty. The present study evaluated whether intermediate to long-term outcomes of total ankle arthroplasty in ankles with preoperative varus and valgus malalignment (5° to 20°) are comparable with those with neutral alignment (<5°). METHODS: We enrolled 144 consecutive ankles that underwent primary total ankle arthroplasty (140 patients) using a mobile-bearing HINTEGRA prosthesis with a minimum follow-up of 4 years; the mean overall follow-up duration was 89 months (51 to 145 months)...

Systolic blood pressure (SBP) and arterial stiffness are closely related and may behave reciprocally as cause or effect, interacting in a vicious cycle. Both SBP and arterial stiffness increase with age in populations in most developed countries. However, the age-related increase in SBP appears to be absent in indigenous populations, partially because of their lifelong low-sodium and high-potassium diets, whereas age-related arterial stiffening in these populations remains to be determined. We performed a field survey of the indigenous population of Soroba, a small village located in the central highlands of Papua, Indonesia...

BACKGROUND: Increased arterial stiffness is reportedly associated with cardiac remodelling, including the left atrium and left ventricle, in middle-aged and older adults. However, little is known about this association in young adults. METHODS: In total, 73 patients (44 (60%) men) aged 25 to 45 years with suspected coronary artery disease were included in the analysis. The left atrial volume index (LAVI), left ventricular volume index (LVVI), and left ventricular mass index (LVMI) were measured using coronary computed tomography angiography (CCTA)...

High plantar flexor moment during the stance phase is known to cause high plantar pressure under the forefoot; however, the effects on plantar pressure due to a change of gastrocnemius medialis (GM) activity during gait, have not been investigated to date. Reciprocal inhibition is one of the effects of electrical stimulation (ES), and is the automatic antagonist alpha motor neuron inhibition which is evoked by excitation of the agonist muscle. The aim of this study was to investigate the influences of ES of the tibialis anterior (TA) on plantar pressure and the GM activity during gait in healthy adults...
