Objectives- The purpose of this study was to determine whether the iliotibial band (ITB) moves relative to the lateral femoral epicondyle (LFE) as a function of knee flexion in both non-weight-bearing and weight-bearing positions in asymptomatic recreational runners. Methods- Five male and 15 female asymptomatic recreational runners (10-30 miles/wk) aged 18 to 40 years were examined with sonography to assess the distance between the anterior fibers of the ITB and the LFE in full extension, 30° of knee flexion, and 45° of knee flexion. Measurements were obtained on both knees in the supine (non-weight-bearing) and standing (weight-bearing) positions. Results- The distance between the anterior fibers of the ITB and the LFE decreased significantly from full extension to 45° of knee flexion in both supine (0.38-cm average decrease; P < .001) and standing (0.71-cm average decrease; P < .001) positions. These changes reflect posterior translation of the ITB during the 0° to 45° flexion arc of motion in both the supine and standing positions. Conclusions- Sonographic evaluation of the ITB in our study population clearly revealed anteroposterior motion of the ITB relative to the LFE during knee flexion-extension. Our results indicate that the ITB does in fact move relative to the femur during the functional ranges of knee motion. Future investigations examining ITB motion in symptomatic populations may provide further insight into the pathophysiologic mechanisms of ITB syndrome and facilitate the development of more effective treatment strategies.

Normative Data for Quantitative Calcaneal Ultrasonometry in Turkish Children Aged 6 to 14 Years: Relationship of the Stiffness Index With Age, Pubertal Stage, Physical Characteristics, and Lifestyle.

Objectives- Quantitative ultrasonometry is commonly used to assess bone health. The aim of this study was to define normative data for the stiffness index of the calcaneus in healthy Turkish children. Methods- Quantitative ultrasonometric measurements of the calcaneus were obtained in 1617 healthy schoolchildren (811 boys and 806 girls) aged 6 to 14 years. Results- The stiffness index increased by 19.3% and 12% in boys and girls, respectively. The greatest increases were seen in the age groups of 12 to 13 and 13 to 14 years in boys (3.9%) and 11 to 12 and 12 to 13 years in girls (4.1%). There was a significant increase in stiffness index values among all Tanner stages except stage 4 (P < .05). Although the stiffness index was related to age, weight, and height, no correlation was seen between the stiffness index and calcium intake or physical activity. Conclusions- This study provides stiffness index data by age group and Tanner stage that may be useful for assessment of the bone status of Turkish children and can serve as comparative data for other patient groups.

Objective: The aims of this study were: (i) to evaluate the immediate effects on subluxation and gait pattern of a new shoulder orthosis, developed for treatment of painful shoulder syndrome in subacute stroke patients; and (ii) to evaluate patients’ and therapists’ opinions about its fit and benefits after 4 weeks. Methods: A total of 40 subacute in-rehabilitation stroke patients with non-functional arm and painful shoulder were included in the study. Of these, 12 subjects underwent shoulder radiography and gait analysis with and without the orthosis to determine the immediate effects of the orthosis. All 40 patients wore the orthosis during the daytime for 4 weeks before completing a survey. Outcome measures were: repositioning of the humeral head, gait cycle parameters, and qualitative lower limb muscle activation patterns. Patients and therapists rated wearing comfort, odour nuisance, effect on pain and performing gait and mobility-related activities. Results: When using the shoulder orthosis the humeral head was repositioned in 10 of 12 patients, patients walked more symmetrically due to a prolonged hemiparetic stance phase (p?HubMed – rehab
