OBJECTIVE To evaluate the effect of pre-season dance training on back pain, joint mobility, and muscle flexibility, and on speed and agility in elite cross-country skiers. METHODS 26 skiers participated (mean (SD) age, 19 (3.9) years). An intervention group (n = 16) had 12 weeks of dance training; a control group (n = 10) did not dance; otherwise both groups followed a similar pre-season phys...

SUMMARY Three genes, including EGFR (epidermal growth factor receptor), CALM3 (calmodulin 3, calcium-modulated protein 3) and SMARCD1 (SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily d member 1), play different roles in bone and/or fat metabolism in Caucasian women. In this population-based investigation of 870 unrelated postmenopausal Caucasian women, CALM3 p...

Background: Machine learning (ML) has emerged as a method to determine patient-specific risk for prolonged postoperative opioid use after orthopedic procedures. Purpose: We sought analyze the efficacy and validity of ML algorithms in identifying patients who are at high following Methods: PubMed, EMBASE, Web Science Core Collection databases were queried articles published prior August 2021 app...

OBJECTIVES To evaluate changes in bone mineral density (BMD) in the hands, hip and spine after 1 and 2 years of follow-up, in relation to antirheumatic and antiresorptive therapies and disease and demographic variables in patients with recent-onset rheumatoid arthritis (RA). METHODS Changes in BMD measured in metacarpals 2-4 by digital x-ray radiogrammetry and in the hip and spine by dual ene...

This study examined the association between physical activity (PA) and bone mineral content (BMC; gram) from middle childhood to middle adolescence and compared the impact of vigorous-intensity PA (VPA) over moderate- to vigorous-intensity PA (MVPA). Participants from the Iowa bone development study were examined at ages 5, 8, 11, 13, and 15 years (n = 369, 449, 452, 410, and 307, respectively)...

PURPOSE The purpose of this study was to compare the effects of a high-load (80%, 1-repetition maximum (RM), 8 reps) and a high-repetition (40%, 1-RM, 16 reps) resistance training protocol on muscular strength and bone mineral density (BMD) in early postmenopausal, estrogen-deficient women. The 6-month programs were matched initially for training volume (3 sets, 3 d x wk(-1)) for 12 exercises s...

We are presenting a case of a 58-year-old-male patient with a congenital hypoplasia of the lower portion of his left psoas muscle. This rare anomaly, which should be differentiated from other pathological conditions (destructive processes, tumors, metastases, inactivate atrophy), was discovered during the MRI examination of his lumbosacral (LS) spine which the patient underwent due to deteriora...

OBJECTIVE To determine hip joint pain referral patterns. DESIGN Retrospective analysis. Setting. Multicenter. Patients. Fifty-one consecutive patients meeting clinical criteria of a symptomatic hip joint. Interventions. Fluoroscopically guided intra-articular hip joint injection. Outcome Measures. Anatomic pain map before hip injection and visual analog scale both before and after hip injecti...

BACKGROUND AND PURPOSE Mechanical hip pain and disease-based hip pain can have similar signs and symptoms, thereby presenting a differential diagnostic challenge for clinicians. Hip pain is a common complaint addressed by physical therapists; therefore, it would be advantageous for them to be knowledgeable about differential diagnosis for hip pain, so that they can screen for possible serious c...

Femoroacetabular impingement syndrome is a common hip pathology significantly affecting not only the intra- and extra-articular structures but also the biomechanical function of the joint. Cam and pincer bony lesions have been extensively studied. However, during recent years, other types of extra-articular impingement between the pelvic and femoral bone have been investigated. When a prominent...
