OBJECTIVE To determine the effects of a weight-bearing rehabilitation program on quadriceps and gluteus medius electromyographic activity, pain, and function in subjects diagnosed with patellofemoral pain syndrome (PFPS). DESIGN Pretest and posttest 6-week intervention study. SETTING Musculoskeletal research laboratory. PARTICIPANTS Fourteen subjects diagnosed with PFPS and 14 healthy con...

The distribution of muscle fibres classified on the basis of their content of different myosin heavy chain (MHC) isoforms was analysed in muscle biopsies from the gluteus medius of adult untrained horses by correlating immunohistochemistry with specific anti-MHC monoclonal antibodies and standard myofibrillar ATPase (mATPase) histochemistry. Percutaneous needle biopsies were taken at 3 depths (...

BACKGROUND The presence of enthesitis (insertional inflammation) in patients with juvenile idiopathic arthritis (JIA) is difficult to establish clinically and may influence classification and treatment of the disease. We used ultrasonography (US) and color Doppler (CD) imaging to detect enthesitis at the small and deep-seated proximal insertion of the gluteus medius fascia on the posterior ilia...

We build the q = −1 defomation of plane on a product of two copies of algebras of functions on the plane. This algebra constains a subalgebra of functions on the plane. We present general scheme (which could be used as well to construct quaternion from pairs of complex numbers) and we use it to derive differential structures, metric and discuss sample field theoretical models. TPJU 4/95 Februar...

This article presents the authors' technique for evaluation of possible abductor tears with magnetic resonance imaging (MRI). By using T2 fat-saturated coronal and axial slices of the hip and T1 coronal images of the pelvis, the authors show how to visualize all tears of the abductor tendons and signs of chronic abductor deficiency. After diagnosis has been made, signs that may help the surgeon...

Introduction: 99mTc-Methylene diphosphonate (99mTc-MDP) three phase bone scintigraphy (TPS) is beneficial to evaluate the success of femoral head revascularization using novel distraction osteogenesis techniques with bone muscle pedicle grafts. This pilot study was undertaken to evaluate the feasibility and utility of 99mTc-MDP three phase bone ...

PurposeTo evaluate the effect of hip flexion and rotation on excursion gluteus medius (Gmed) minimus (Gmin) myotendinous unit.MethodsSeven hips from 4 cadaveric specimens (males, 68.5 ± 18.3 years old) were dissected to isolate Gmed posterior lateral insertions Gmin proximal distal insertions. Sutures placed tendon through origins created in iliac fossa simulate unit. A load 10N was applied. My...
