In a 30-year study of nearly 100,000 females, French researchers found that females who exercised the most had a 25% lower rate of Parkinson’s disease compared to those who exercised the least. While the study does not prove that exercise lowers the risk of developing Parkinson’s disease, it does show an association.

Patellofemoral Joint Geometry and OA
In this cross-sectional study, international researchers compared patellofemoral geometry in individuals with a youth-sport-related intra-articular knee injury to uninjured individuals, and the association between patellofemoral geometry and magnetic resonance imaging (MRI)-defined osteoarthritis…
BFRRE Improves Muscle Functional Capacity in Older Adults
Low-load blood flow-restricted resistance exercise (BFRRE) constitutes an effective means to produce skeletal muscle hypertrophy in as little as 6 weeks. Its applicability to counteract the age-related skeletal muscle decay at a cellular level, however, is not clear. Danish researchers investigated the effect of BFRRE on…
Muscle Synergies in Chronic Ankle Instability
Lateral ankle sprains are among the most common musculoskeletal injuries. Indeed, nearly 70% of these patients will go on to develop chronic ankle instability (CAI) with lingering mechanical and functional deficits. Although neuromuscular deficits in people with CAI have been identified, previous…
To Decrease Pain, Increase Physical Activity
A randomized controlled trial from Japan examined whether compared with a program without increased physical activity, an intervention program with increased physical activity could prevent the development of musculoskeletal pain in community-dwelling older adults.
Bone Stress Injuries at the Ankle and Foot
Writing in Seminars in Musculoskeletal Radiology, 2 European experts review typical anamnestic/clinical findings, epidemiology and risk factors, imaging characteristics, and findings at typical locations of bone stress injuries in the foot and ankle that may help guide treatment strategy and patient recovery.
Pooled Analysis: 75 mins/wk of Moderate Physical Activity Prevents 1/10 Deaths
One in 10 early deaths could have been prevented if everyone had met just half the recommended weekly target of 150 minutes of moderate intensity physical activity, according to the largest pooled data analysis of its kind.
Measuring Sarcopenia
Sarcopenia is associated with adverse outcomes in elderly persons, including functional disability, falls, and even death. Therefore, older adults should be routinely screened for sarcopenia. Due to the unsatisfactory sensitivity of the SARC-F questionnaire, 4 modified versions have been elaborated: SARC-CalF (calf measurement)…
New Guideline For Timing of Elective TJA
The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) released a summary of the new guideline for hip and knee replacement timing titled “The Optimal Timing of Elective Hip or Knee Arthroplasty for Patients with Symptomatic Moderate to Severe Osteoarthritis or Osteonecrosis Who Have Failed Nonoperative Therapy.”
