Recently multiple cutaneous leiomyomas, uterine leiomyoimatosis and renal cancer have been described as a cancer syndrome with autosomal dominant pattern of inheritance.We report a 79-year-old man who presented with multiple hyperkertotic erythematous nodules on his right leg with histological diagnosis of pilar leiomyoma. In his past medical history several systemic co...

introduction: knee joint has the highest percentage of injuries among lower extremity joints especially in athletes and people with high activity levels. therefore, analyzing of knee movements has an important area of research in the bioengineering and rehabilitation fields. sharif human movement instrumentation system (sharif-hmis) is a new inertial sensor designed for movement analysis. the p...

The study aimed to investigate the impact of a 12-week strength training program on force accuracy and steadiness changes in lower limbs young healthy men. Twenty subjects with dominant right limb were included. They performed matching task both pre post program. ability reproduce was determined by calculating three errors: absolute error (AE), constant (CE), variable (VE). After intervention A...

Autism represents a disorder of neural development characterized by 3 features including deficit in social communication, inflexibility of speech and behavior, and stereotyped movements. The prevalence of this disorder has been reported about 1.5 per 100 individuals in Iran. Individuals with ASDs are susceptible to weakness in balance and stability and also postural deformities. Thus, the pur...

Congenital deficiency of the tibia (tibial hemimelia, aplasia, or dysplasia) also known as long bone deficiency is a rare and severe lower limb malformation, with an incidence of approximately 1:1,000,000 live births. It is characterized by lack of part or the entire tibia, with relatively intact fibula. Usually the affected leg is rotated externally and the ventral surface of the foot faces th...

UNLABELLED Several genes have been mapped in families or in sporadic cases of dystonia. TOR1-A (DYT1) gene was linked to isolated dystonia. OBJECTIVE To associate clinical information of patients with dystonia with the TOR1-A gene mutations. METHOD Eighty-eight patients with dystonia in cervical area (focal, segmental, multifocal and generalized) were recruited at Movement Disorders Clinic ...

A 28-year-old woman presented with severe, persistent burning pain in the legs and feet, with marked erythema, swelling, and warmth (Fig. 1, left-hand panels). The erythema had begun at the age off our years, with no associated disorder. After adolescence, the symptoms became continuous, with erythema that extended to the thighs and the development of live do-like lesions. Burning pain during t...

The purpose of this study was to examine the effects of diverting activities on electromyographic amplitude and mean frequency. On three separate occasions, eleven men and eight women performed two bouts of fifty consecutive maximal concentric isokinetic muscle actions of the dominant leg extensors. Between these bouts, the subjects either solved math problems, performed contralateral dynamic c...

Context: Isokinetic strength and functional performance are used to assess recovery after rehabilitation. It is not known whether low-speed closed-linear-kinetic isokinetic muscle strength correlates with functional performance. Objective: To investigate the relationship between linear closed (CKC) and open (OKC) concentric isokinetic strength of the dominant lower-limb extensors and functional...

INTRODUCTION The purpose of this study was to examine the influence of fatigue on the average firing rate versus recruitment threshold relationships for the vastus lateralis (VL) and vastus medialis. METHODS Nineteen subjects performed ten maximum voluntary contractions of the dominant leg extensors. Before and after this fatiguing protocol, the subjects performed a trapezoid isometric muscle...
