When balance is exposed to perturbations, hand contacts are often used to assist postural control. We investigated the immediate and the transitionary effects of supportive hand contacts during continuous anteroposterior perturbations of stance by automated waist-pulls. Ten young adults were perturbed for 5 min and required to maintain balance by holding to a stationary, shoulder-high handle and following its removal. Center of pressure (COP) displacement, hip, knee and ankle angles, leg and trunk muscle activity and handle contact forces were acquired...

Gordon syndrome or distal arthrogryposis type 3 is a rare autosomal dominant disorder characterized by contractures of upper and lower limbs. It is distinguishable from other forms of distal arthrogryposis by cleft palate and short stature. Recently, Gordon syndrome has been associated to heterozygous mutations in the piezo-type mechanosensitive ion channel component 2 gene (PIEZO2). Different mutations of this gene also cause distal arthrogryposis type 5 and Marden-Walker syndrome. Dysfunction of this ion channel provides pleiotropic effects on joints, ocular muscles, and bone development...

[Purpose] The purpose of the present study was to examine the validity of functional reach models by comparing actual values with estimated values. [Subjects and Methods] Twenty-eight volunteers were included in this study (male: 14, female: 14, age: 21 ± 1 years, height: 166.8 ± 9.0 cm, and body mass: 60.1 ± 8.5 kg). The maximum forward fingertip position and joint angles were measured using the original equipment. In addition, the maximum forward fingertip position, shoulder joint angle, and knee or ankle joint angle were estimated using the functional reach model...

Despite many nonbattle injuries reported during deployment, few studies have been conducted to evaluate the effects of deployment on musculoskeletal and physiological characteristics and balance. A total of 35 active duty U.S. Army Soldiers participated in laboratory testing before and after deployment to Afghanistan. The following measures were obtained for each Soldier: shoulder, trunk, hip, knee, and ankle strength and range of motion (ROM), balance, body composition, aerobic capacity, and anaerobic power/capacity...

PURPOSE: To assess the effects of mobility training on severe burn patients in the Burn Intensive Care Unit (BICU). METHODS: This was a retrospective cohort study. Severe burn patients with equal to or more than 50% Total Body Surface Area (TBSA) burns who received early rehabilitation in the BICU were included in this study. Based on the different early rehabilitation strategies during the two periods, patients admitted to the BICU from January 2011 to April 2013 were identified as the passive training cohort (n=49) while patients admitted to the BICU from May 2013 to December 2013 were identified as the mobility training cohort (n=24)...

OBJECTIVE: Ultrasonography has been prevalently used as a valid and objective modality for joint examination in patients with rheumatoid arthritis (RA). This study aimed to examine and compare the concordance between ultrasound, clinical, and patient-reported assessment of joint synovitis in RA. METHODS: Fifty patients with RA (84% female; median age, 69 years; disease duration, 2.6 years; disease activity score of 28 joints, 3.8) completed the self-evaluation of joint symptoms including pain and considerable stiffness in the (proximal) interphalangeal, metacarpophalangeal, wrist, elbow, shoulder, knee, and ankle joints...

BACKGROUND: Patients often ask their doctors when they can safely return to driving after orthopaedic injuries and procedures, but the data regarding this topic are diverse and sometimes conflicting. Some studies provide observer-reported outcome measures, such as brake response time or simulators, to estimate when patients can safely resume driving after surgery, and patient survey data describing when patients report a return to driving, but they do not all agree. We performed a systematic review and quality appraisal for available data regarding when patients are safe to resume driving after common orthopaedic surgeries and injuries affecting the ability to drive...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a disease that is characterized by chronic airflow limitation, a variety of pathological changes in the lungs, significant extrapulmonary manifestations, and severe comorbidities which may further aggravate the course of COPD [GOLD, 2013]. Intensity of systemic manifestations increases with the progression of obstruction, therefore the abovementioned symptoms are often overlooked and become apparent in the later stages of the disease...

Our objective was to study the incidence, etiology, and diagnosis of multifocal osteonecrosis (MFON) and its treatment options to facilitate an earlier diagnosis and to optimize treatment. A radiological investigation was performed in osteonecrosis patients with a high risk of MFON for a more accurate diagnosis between January 2010 and June 2015. For patients with osteonecrosis of both the hip and knee joints or for patients with a history of corticosteroid use or alcohol abuse who had osteonecrosis of one or more joints in the shoulder, ankle, wrist or elbow, magnetic resonance imaging (MRI) was also performed on other joints, regardless of whether these joints were symptomatic...

As the overall survival rate for burn injury has improved, increased emphasis is placed on postburn morbidity and the optimization of functional and cosmetic outcomes. One major cause of morbidity and functional deficits is that of joint contractures. The true incidence of postburn contractures and their associated risk factors remains unknown. This study examines the incidence and severity of contractures in a large, multicenter, burn population. The associated risk factors for the development of contractures are determined...

Joint contractures are a major cause of morbidity and functional deficit. The incidence of postburn contractures and their associated risk factors in the pediatric population has not yet been reported. This study examines the incidence and severity of contractures in a large, multicenter, pediatric burn population. Associated risk factors for the development of contractures are determined. Data from the National Institute on Disability and Rehabilitation Research Burn Model System database, for pediatric (younger than 18 years) burn survivors from 1994 to 2003, were analyzed...

Aspergillus septic arthritis is a rare and serious medical and surgical problem. It occurs mainly in immunocompromised patients. Aspergillus fumigatus is the most common causative organism followed by Aspergillus flavus. The most common site affected is knee followed by shoulder, ankle, wrist, hip and sacroiliac joint. Debridement and voriconazole are primary treatment of articular aspergilosis. To the best of our knowledge, there are no reported cases of co-infection of tuberculosis (TB) and Aspergillus infecting joints...

BACKGROUND/AIM: The Sailing World Championships 2014 was contested by 1167 sailors in all 10 Olympic classes. Our objective was to characterise sailing-related injuries and illnesses in sailors participating in this regatta. METHODS: We conducted 2 surveys: (1) prior to the World Championships, sailors answered a 12-month recall questionnaire on sailing-related injuries and illnesses and (2) during the Championships, injuries and illnesses were documented. RESULTS: There were 760 respondents (65% of all participants) for the 12-month recall questionnaire (58% male, 42% female), of whom 244 participants reported 299 injuries (0...

Since its inception, arthroscopic surgery has become widely adopted among orthopedic surgeons. It is therefore important to have an understanding of the basic principles of arthroscopy. Compared with open techniques, arthroscopic procedures are associated with smaller incisions, less structural damage, improved intra-articular visualization, less pain in the immediate postoperative period, and faster recovery for patients. Pump systems used for arthroscopic surgery have evolved over the years to provide improved intraoperative visualization...

OBJECTIVES: The objective of this study was to investigate the relationship of degenerative joint disease (DJD) features (marginal lipping, porosity, surface osteophytes, eburnation, and loss of joint morphology) with sex, age, and occupation. MATERIALS AND METHODS: We devised a recording method for scoring the single features in the shoulder, elbow, wrist, hip, knee, and ankle of an Italian skeletal sample of 332 individuals (males = 161, females = 171) of known sex, age, and occupation from the Frassetto collection (Sassari, Sardinia, 19th-20th century)...
