“Whiplash” injuries are defined as sudden acceleration-deceleration of the head resulting in damage to the cervical spine. While most common in motor vehicle accidents (MVA), whiplash can occur as a result of other high-speed activities such as sports. Usually characterized by long-standing chronic neck pain and disability, studies have shown that patients with whiplash-associated disorders (WAD) have specific patterns of muscle weakness and tightness. Exercise for whiplash and neck pain have been shown effective. Previous research by Dr. Jari Ylinen in Finland has shown that Thera-Band® resistance band exercises are effective at reducing chronic neck pain for up to 2 years.

Researchers in Norway wanted to compare 2 types of exercise programs on patients with whiplash. 25 patients were randomly assigned to a strength and endurance group or a “motor control” exercise group during 6 weeks of physical therapy. The motor control group performed 10 repetitions of deep neck flexor activation against an inflatable blood pressure cuff. The strengthening group used elastic bands to strengthen their neck muscles and dumbbells to strengthen the upper More >
Study Shows Resistance Exercises Using Thera-Band Elastic Tubing and Dumbbells Produce Similar Levels of Muscle Activation
Mar 5th
Akron, OHIO: High-intensity resistance training plays an essential role in the prevention and rehabilitation of musculoskeletal injuries and disorders. Although resistance exercises with heavy weights yield high levels of muscle activation, the efficacy of more user-friendly forms of exercise needed to be examined.
“We were interested in a study that would confirm that elastic resistance is as effective as isotonic resistance without the hassle of dumbbells,” stated Phil Page PhD, PT, ATC, Director of Research and Education for Thera-Band Academy. “The convenience and accessibility of elastic bands and tubing can be very beneficial for patients continuing their exercises at home.”
Lars L. Andersen, PhD, and Mette K. Zebis, PhD, researchers with the National Research Centre for the Working Environment in Copenhagen, Denmark, completed a recent research study to investigate muscle activation and perceived loading during upper-extremity resistance exercises with dumbbells compared to elastic tubing.
The findings of this study were published online ahead of print on Feb. 4, 2010, by the American Physical Therapy Association at www.ptjournal.apta.org, the Web site of the Association’s journal, Physical Therapy (PTJ).
The article can be accessed at http://ptjournal.apta.org/future/90.4.dtl and will be published in print in the April 2010 issue.
The study involved 16 healthy female workers, aged 26–55 years, working More >
The Best Exercises for Rotator Cuff Strengthening
Mar 2nd
For years, the debate has continued on the ‘best’ exercises for strengthening shoulder muscles. Using electromyography (EMG) to measure muscle activity, researchers have attempted to determine which exercises have the highest levels of muscles activity for strengthening exercises. Several studies have examined EMG of common shoulder exercises to find the best exercises to strengthen the rotator cuff; in particular, the supraspinatus muscle. The “empty can” or “full can” exercises have been the most commonly performed exercise for supraspinatus strengthening, but controversy still exists in the literature.
While high muscle activation levels are often desirable, what’s more important is the relative activation of other muscles during the movement. For example, Dr. Michael Reinold and colleagues suggested in their 2007 paper that a good rotator cuff exercise should produce the greatest supraspinatus activity while minimizing the deltoid activation. Theoretically, reducing deltoid activation decreases the upward shear of the humerus during arm elevation, which may be desirable when prescribing exercise to strengthen the suprapsinatus in impingement patients.
In a study published in Medicine and Science and Sports and Exercise, subjects performed 5 isometric exercises in random order while measuring the EMG activity of the deltoid, supraspinatus, and infraspinatus. The exercises were: full can, empty can, prone elevation, elastic external More >
Are elastic resistance squats better than free weight squats?
Mar 1st
The squat exercise is used primarily for hip and knee strengthening. It is considered one of the most fundamental strengthening exercises for strength and power in the legs. Elastic bands have been used to add resistance to the squat exercise while using barbell free weights to offer more dynamic resistance at the top of the squat movement as the resistance of the band is at its highest. No studies have directly compared the effects of squatting with elastic resistance versus free weights.
In a study published in the Journal of Strength and Conditioning Research, researchers compared squatting with equivalent work loads of elastic-resisted and isotonic free-weight squats in trained weight lifters. Subjects squatted with each type of resistance while muscle activity and biomechanical variables were measured. The band-resisted squats resulted in higher force, velocity, power, and quadriceps muscle activity near the top of the squat, which includes the first part of the eccentric phase, as well as the last part of the concentric phase.
The researchers concluded that elastic resistance produces similar resistance patterns as standard free weights, except at the bottom of the squat, where the bands are on less stretch and thus, less tension. More importantly, the researchers stated that elastic band squats More >
Thera-Band® exercise helps improve bone density and reduce falls in osteoporosis
Feb 24th
It’s been well-established that exercise has numerous health benefits, yet it is only relatively recently that exercise has been shown safe and effective at improving health and quality of life in older adults.
Recent recommendations from the Centers for Disease Control (CDC) and American College of Sports Medicine include strengthening exercises for older adults at least twice a week. Strength training can improve muscular strength, power and endurance in older adults. In addition, strength training can increase bone mass or decrease bone mass loss which is particularly important in women with osteoporosis. Falls in osteoporotic women in particular often lead to fractures of the hip, back, and arm.
Researchers in Germany set out to determine if a well-rounded exercise program that included Thera-Band® resistance bands would be effective at increasing bone density, decreasing falls, and improving cardiovascular risk factors in older women. In the study, published in the Archives of Internal Medicine, 246 women over 65 years old were randomly assigned to either a high-intensity/low volume “well-rounded” exercise program, or a low-intensity “wellness” exercise control group. The 18 month exercise program included 2 group sessions per week and 2 home-based sessions per week.
The well-rounded exercise group protocol included cardiovascular warm-up exercises, upper body strengthening exercise using More >
