Heavy Loads on the Shoulders Can Cause Nerve Damage in The Hands And Fingers

  Medical News Today

Trudging from place to place with heavy weights on our backs is an everyday reality, from schoolchildren toting textbooks in backpacks to fire fighters and soldiers carrying occupational gear. Muscle and skeletal damage are very real concerns. Now Tel Aviv University researchers say that nerve damage, specifically to the nerves that travel through the neck and shoulders to animate our hands and fingers, is also a serious risk.

Steroid injections for tennis elbow are out

HEALTH NEWS OBSERVER

Tennis elbow is also known as lateral epicondylitis. In tennis elbow, the tendons that attach the forearm muscles to the outer part of the elbow degenerate, become inflamed and develop tears. Tennis players often irritate this area during backhand strokes. Anyone who uses a twisting motion is at risk including painters, carpenters, plumbers, cooks, weight lifters, and butchers. It may also develop by some who are constantly using a computer keyboard and mouse.

What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome is a condition in which there is progressive pain, numbness and eventually weakness in the hand and wrist, caused by increased pressure on the median nerve in the wrist. The carpal tunnel is a narrow space through which nine tendons and one nerve cross the wrist to reach the hand.

FDA clears Soft Tissue Regeneration’s STR GRAFT

News Medical

Soft Tissue Regeneration, an early stage orthopedic device company that has developed a breakthrough tissue engineering platform used to regenerate ligaments and tendons, announced today that it has received FDA clearance to market its STR GRAFT, a biodegradable scaffold used for soft tissue augmentation and rotator cuff repair.

Developed by Cato T. Laurencin , M.D., Ph.D., an orthopedic surgeon and the company’s founder, the STR GRAFT is a three-dimensional braided engineered matrix that Laurencin likens to a patch. During surgery, surgeons can drape this biodegradable patch over the tendon that sits on the shoulder bone, anchoring it with sutures to keep it in place while the tendon, bones and nearby tissues heal. Unlike currently available devices, which are made of weaker cadaver or animal tissue that can cause sutures to pull, the STR GRAFT is thinner—about 1 millimeter—and stronger, which lessens pain, speeds recovery time and drastically reduces surgical failure rates.

Newly approved oral medication slows rheumatoid arthritis joint damage

Science Daily

A Phase 3 clinical trial demonstrates that tofacitinib improves disease activity and inhibits progression of joint damage in rheumatoid arthritis (RA) patients who did not respond to methotrexate (MTX). Results of the 12-month interim analysis of the efficacy of tofacitinib appear in Arthritis & Rheumatism, a journal published by Wiley on behalf of the American College of Rheumatology (ACR).

RA is a chronic, autoimmune disease that causes inflammation, pain and swelling of the joints. Over time, RA may destroy joints, impair daily function, and lead to significant disability. The World Health Organization (WHO) estimates that RA affects up to one percent of individuals worldwide and 1.3 million of those are Americans according to the ACR.

Combining Motor Imagery And Physical Practice Enhances Performance

Adding movement to mental rehearsal can improve performance finds a study in BioMed Central’s open access journal Behavioral and Brain Functions. For high jumpers the study shows that dynamic imagery improves the number of successful attempts and the technical performance of jumps.

The technique of mental rehearsal is used to consolidate performance in many disciplines including music and sport. Motor imagery and physical practice use overlapping neural networks in the brain and the two together can improve performance as well as promoting recovery from injury. Researchers from the Centre de Recherche et d’Innovation sur le Sport found that adding simple movements to mental rehearsal could further improve performance by a third.

Physical Activity Really Does Enhance Cognition

Medical News Today

Exercise doesn’t only strengthen your heart and muscles – it also beefs up your brain. Dozens of studies now show that aerobic exercise can increase the size of critical brain structures and improve cognition in children and older adults.

University of Illinois psychology professor Art Kramer, a nationally recognized expert on the role of physical fitness on cognition, discussed these brain-changing outcomes at a session of the 2013 meeting of the American Association for the Advancement of Science in Boston. Kramer is the director of the Beckman Institute for Advanced Science and Technology at the U. of I.

New treatment for tennis elbow
Source eorthopod.com

Steroid injections are no longer routinely recommended for lateral epicondylitis (tennis elbow). Instead, physical therapists offer an alternative treatment in the form of something called iontophoresis.

In this article, the use of steroid injection is compared with iontophoresis delivered in two different ways. Iontophoresis uses a small electric current to drive steroid medication through the skin. It is a noninvasive method of reducing the pain of tennis elbow.

A new angle on tennis injuries offered by markerless motion capture
Source: Medical News Today

Researchers studied three types of tennis serves, and identified one in particular, called a “kick” serve, which creates the highest potential for shoulder injury.

The study examined the difference in body positioning for the three serves. Researchers measured the distance between the vertical center line of a player’s body and the hitting surface of the racquet when the player hit the ball. For the kick serve, players swung the racquet closer to the center – about 21 cm (8 inches) and 16 cm (6 inches) closer than for the flat serve and slice serve, respectively. The players also extended the racquet farther behind them for the kick serve: 8 cm (3 inches) farther than for the flat serve.

Pitchers: Elbow position not a predictor of injury
Source: Science Daily

Elbow position alone appeared to not affect injury rates and performance in college-level, male pitchers say researchers presenting at the American Orthopaedic Society for Sports Medicine’s Specialty Day in San Francisco, CA.

“The elbow’s position in relation to an injury and enhanced performance in baseball pitchers is highly dependent upon the trunk’s position,” said lead researcher, Carl W. Nissen, MD of Elite Sports Medicine and Connecticut Children’s Medical Center in Farmington, CT. “Our research showed that the pitching motion is complex and a direct relationship between true elbow position and how much stress is placed on a joint does not appear to exist.”
