Thera-Band® resistance helps female cancer survivors keep fit after chemotherapy
Aug 10th
Breast cancer survivors often experience weight gain after chemotherapy, particularly pre-menopausal women. This weight gain has been associated with an increased recurrence and death from breast cancer (Chlebowski et al. 2006). Researchers at the University of Washington and Oregon Health Sciences University suggested that exercise may be a low-cost, non-pharmacologic strategy to prevent or reverse weight changes in female cancer survivors. In their randomized controlled study, 112 women newly diagnosed with cancer were randomly assigned to a resistance exercise group, aerobic exercise group, or a control group (usual care). Both exercise groups performed their routines 4 times per week at their home for 12 months. Each exercise routine took 20 to 30 minutes and the exercises used the Borg Scale to maintain a “moderate” intensity level.
The resistance exercise group used Thera-Band® resistance bands or weight equipment in their home. They performed 3 to 4 upper and lower body exercises for 2 sets of 12 to 20 repetitions with progression in the resistance levels. The aerobic exercise group performed enjoyable weight-bearing activities such as walking, jogging, or dancing. Subjects were assessed before the study, half-way through the study (6 months), and at the end of the 12 month study for body weight, More >
Thera-Band® exercises reduce pain and improve muscle function in Air Force helicopter pilots
Aug 9th
It’s been estimated that 50% of military helicopter pilots experience neck pain in the previous year, likely due to the postural demands and helmet-mounted technology. Physical therapist researchers in Sweden investigated the effectiveness of a neck exercise program for Swedish Air Force helicopter pilots and reported their findings in Spine. They measured the incidence of neck pain and EMG activity of neck muscles during a cranio-cervical flexion test in 68 active-duty pilots that were randomly assigned to an exercise or control group.
An experienced physiotherapist supervised the exercises which were performed 1 to 2 times a day for 10 to 15 minutes with 2 to 4 exercises. The exercises were individually prescribed and progressed by the physiotherapist based on the pilots’ progress toward motor control and movement quality, rather than a specific number of sets and repetitions. Pilots progressed through a specific set of exercises over 6 weeks. Using Thera-Band resistance bands, the exercises gradually challenged the neck and shoulder muscle function from non-postural to postural exercises, and endurance-strength exercises.

After the 6-week program, the exercise group significantly decreased their muscle activation levels (measured with EMG) of the sternocleidomastoid (SCM) muscle during the cranio-cervical flexion test More >
Thera-Band® exercises improve kyphotic posture in women
Jul 22nd
It’s generally accepted that our posture declines as we age. Researchers at the University of Kansas Department of Physical Therapy examined the natural progression of thoracic kyphosis in healthy women. They found that kyphosis increases in females with age, particularly between 50 and 59 years of age. The researchers then established an exercise program for healthy women aged 50-59. For one year, 81 women were asked to perform spinal extension exercises including elastic band resistance (Click here to download the Spinal Extension Exercise protocol) 3 times per week. Cervical and thoracic spinal curves were measured before and after the program.
After 1 year, the researchers determined which women were compliant or non-compliant. The remaining women who had performed exercise irregularly were excluded (46 women) from analysis, leaving a total of 35 women in the analysis. The researchers found that those women who did not perform the exercises had a greater progression of poor posture, particularly increasing in thoracic kyphosis.
The researchers noted that these results are only applicable to relatively healthy women without spinal abnormalities. In addition, they suggested that women with symptomatic spinal stenosis should not perform these exercises. While these results are encouraging, poor compliance was an issue: only 18% consistently performed the exercises. More >
Thera-Band exercises effective for acute ankle sprains
Apr 20th
Ankle sprains are the most common injury in sports. Rehabilitation exercise after ankle sprains include active and resisted exercises, often performed with a Thera-Band® elastic band. Reduced ankle dorsiflexion range of motion (ROM) is considered to be a sign of significant injury and can affect gait and function.
Researchers at the Mayo clinic in Rochester, Minnesota recruited patients with acute (within 4 days) Grade I or II ankle sprains. They were prescribed a 4 to 6 week home exercise program that included cold and compression, along with progressive resisted exercises using an elastic band. Patients performed resisted dorsiflexion, plantarflexion, inversion, and eversion with a yellow Thera-Band resistance band, completing 3 sets of 10-20 repetitions, one to two times per day. The patients progressed through the remainder of the Thera-Band color-coded progression (red, green, blue, black, and silver) as they improved in strength. Once the patients could perform 3 sets of 10-20 repetitions of resisted plantar flexion, they began calf raises. They also performed single-leg balance exercises including standing on foam pads. In addition to the Thera-Band and balance programs that the patients received, participants were randomly assigned to one of 3 groups of stretching the Achilles tendon on increase dorsiflexion. Each group performed 3 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 >
