Exercise as good as surgery for knee arthritis
Knee osteoarthritis affects millions around the world with pain and disability. There is no known cure for arthritis, and the course of treatment is based on symptom management through medication, surgery and physical therapy. Some arthritis sufferers believe that exercise may cause more harm than good, and typically opt for arthroscopic surgery to ‘clean-out’ the knee. In addition to the cost of surgery, there are obvious risks. Despite the high number of arthroscopic surgeries for knee arthritis (also known as “debridement”), little evidence supported its efficacy.
Researchers from the University of Western Ontario in Canada performed a randomized controlled trial (the highest level of evidence) on 190 patients with moderate to severe knee osteoarthritis. Their goal was to determine if physical and medical therapy was as effective as arthroscopic surgery. The exercise program lasted for 12 weeks, including one hour per week supervised by a therapist, and daily exercise twice a day. After the 12 weeks, the patients continued their home programs unsupervised.
The researchers found that physical therapy, including Thera-Band exercises was as effective as arthroscopic surgery for treating knee osteoarthritis. Both groups had similar outcomes for pain and function after a 2 year follow-up. The results, published in the New England Journal of Medicine, suggest a structured physical therapy program including Thera-Band elastic resistance can be as effective as arthroscopic surgery for knee osteoarthritis.

Thera-Band® resistance vital part of older adult home exercise study
about 3 weeks ago - No comments
Thera-Band® Academy has been supporting clinical research projects around the world for over a decade. The research helps validate the use of Thera-Band products and provides clinicians with evidence to support practice. Several years ago, the First Step to Active Health® program was developed in response to a “call to action” by the National Blueprint
Thera-Band® exercises safe and effective for patients with hemophilia and bleeding disorders
about 2 months ago - No comments
Bleeding disorders such as hemophilia may cause bleeding in the joints, known as ‘hemarthrosis.’ This may lead to arthritis and subsequent joint replacement surgery. Exercise is an important component in managing hemarthrosis; however, many patients are hesitant to exercise for fear of injury and resulting bleeding. Few studies have examined the effectiveness of exercise in
Thera-Band® exercise program for total knee replacement featured in Lower Extremity Review

Ongoing research at the University of Louisville and Bellarmine University is investigating the effectiveness of Thera-Band® resistance band exercises before surgery for total knee arthroplasty (TKA). “Prehabilitation” consists of pre-operative exercises that are meant to improve strength and functional levels before surgery with the expectation of better rehabilitation and a faster recovery after surgery. The
Systematic review supports use of elastic resistance exercise for shoulder impingement
about 5 months ago - No comments
Shoulder impingement is a common cause of chronic shoulder pain that can be treated with exercise. Impingement can be caused by a structural narrowing of the space between the humeral bone and acromion of the scapula, or by a muscle imbalance of the rotator cuff and/or scapular stabilizer muscles. These types of impingement are referred
It’s not too late to exercise years after knee arthroscopy
about 6 months ago - No comments
Meniscus tears in the knee are relatively common, particularly in middle-aged athletic individuals. Arthroscopic surgery is often performed to remove damaged cartilage. Surprisingly, some orthopedic surgeons do not prescribe physical therapy after knee arthroscopy, feeling patients can recover on their own with a few simple exercises. Unfortunately, this may lead to long-term deficits in strength,
Elastic resistance exercise safe and effective for kidney failure patients on dialysis
about 6 months ago - No comments
The kidneys serve an important function in filtering the blood. Patients with severe kidney disease or kidney failure don’t have the ability to clean their blood. This condition is known as end-stage renal disease (ESRD), and often requires hemodialysis that cleans the blood with a machine. In 2006, over 500,000 Americans had ESRD, with over
Thera-Band® resistance or dumbbells? New research supports both in the clinic

The debate of elastic resistance versus isotonic resistance Elastic resistance is commonly used in rehabilitation exercises, and has been shown to increase strength and function in over 100 randomized controlled trials (www.thera-bandacademy.com). Even with this amount of clinical evidence, elastic resistance is sometimes criticized because of the difficulty in quantifying intensity. Despite the fact
Early Thera-Band® strengthening for rotator cuff tear repair may speed recovery
about 7 months ago - No comments
The rotator cuff is crucial for proper function of the shoulder and activities of daily living (ADL). Full-thickness rotator cuff tears require surgical repair and a lengthy recovery, often lasting 6 months or more. Early physical therapy exercises are very conservative, focusing more on allowing the repair to heal. For fear of re-injury, dynamic resistance
Thera-Band® program helps improve lower extremity strength and biomechanics in female athletes
about 7 months ago - No comments
Anterior cruciate ligament (ACL) tears occur in about one in every 3000 Americans; 80% of these injuries are non-contact, often requiring surgical reconstruction. Female athletes have a higher incidence of ACL injury, likely due to biomechanical differences compared to males. Research has focused on exercise programs that help improve these biomechanics in order to prevent
Thera-Band® elastic bands as effective as expensive weight machines

Muscle strengthening activities are now recommended as part of a regular exercise program. The recent Physical Activity Guidelines issued by the Centers for Disease Control (CDC) in the United States recommend strengthening exercises for all adults at least twice a week. Unfortunately, only about 20% of adults participate in regular strengthening exercises (CDC, 2006). Access
