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 >
Neuromuscular training program reduces injury and improves performance in female athletes
Jul 20th
Balance training using Thera-Band® Stability Trainers and balance boards has been shown to prevent sports injuries in several studies. Researchers in Finland investigated the effects of an in-season neuromuscular training program in female floorball players. 27 teams were randomized into either a control group or intervention group that performed a 6-month neuromuscular exercise program. Each team was provided with an instruction book, 8 wobble boards, 8 balance pads, and 8, 1-kg soft weights. The program (download the sports neuromuscular warm-up protocol here) included balance, agility, plyometric, and stretching exercises.
After the 6-month season, participants in the exercise group significantly improved their static balance and jumping speed. There was no difference in improvement between groups in their jump height or agility running speed. In addition, the researchers found 66% lowered risk for leg injuries in the exercise group (the authors published a separate article in the British Medical Journal in 2008). These studies show that an in-season neuromuscular training program including Thera-Band stability trainers, wobble boards, and soft weights can prevent injury and improve performance in female athletes.

Exercise Ball Core Muscle Activation: Which exercises are best?
Jul 15th
Thera-Band® exercise balls are used by therapists and trainers around the world for therapy and fitness training. Despite its widespread use, the exercise ball has lacked in research to support its clinical application. Some studies have shown that abdominal exercises performed on exercise balls produce more muscle activation than the same exercise performed on a stable surface (Vera Garcia et al. 2000). In addition to traditional abdominal crunches, the exercise ball offers a variety of exercises aimed at activating the core muscles. With the variety of exercises being performed on exercise balls, more research is needed to prove or disprove the efficacy of specific exercises.
Roll Out
Physical therapy researchers quantified the electromyographic (EMG) activity of the abdominals, latissimus dorsi, lower back, and quadriceps muscles during eight “core” exercises on the exercise ball in 18 healthy subjects. They reported their findings in the Journal of Orthopedic and Sports Physical Therapy.
They found that the upper and lower rectus abdominus muscle were most activated during the roll-out (63% and 53% of maximum, respectively), and pike exercises (47% and 55%), while the internal and external obliques were most active during the pike (84% and 56% respectively) and skier exercises (73% and 47%). Not surprisingly, the lumbar paravertebral More >
Functional rehabilitation of chronic ankle instability effective
Jul 12th
It’s been reported that athletes suffering an ankle sprains re-injure their ankle 70% to 80% of the time. This leads to chronic ankle instability or ‘functional ankle instability’. Rehabilitation for chronic ankle sprains often includes functional exercises including dynamic closed-chain activities. Thera-Band® products such as elastic resistance bands, stability trainers and balance boards are used for functional rehabilitation.
Researchers at the University of Toledo performed a systematic review of functional exercise interventions for their effectiveness. They identified 6 studies that met their criteria for the review, including 4 that used balance boards and elastic resistance strengthening. The researchers concluded that functional rehabilitation improves dynamic balance and self-reported function in patients with chronic ankle sprains. The exercise programs from the reviewed studies generally lasted 4 to 6 weeks and were performed 3 to 5 times a week. Finally, they pointed out that wobble board training in rehabilitation programs is “supported by the literature”; therefore, Thera-Band balance boards should be a standard component of chronic ankle instability rehabilitation program.

Thera-Band® exercises safe and effective for patients with hemophilia and bleeding disorders
Jun 29th
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 hemophilia patients.
Previously, German researchers created a strength and proprioceptive training program using Thera-Band elastic resistance and Stability Trainers. The results, published in 2003 noted improvements in strength and proprioception. The authors felt that a balance training component was important to prevent fall-related injuries in persons with hemophilia.
More recently, researchers at the University of Tennessee Health Sciences Center created an individualized 6-week program using Thera-Band resistance in 33 patients with bleeding disorders. They used 3 levels of progression based the participant’s strength. Download the Thera-Band exercise protocol here. The patients then used a specific color of Thera-Band resistance corresponding to the prescribed intensity (% of an isometric manual muscle test). Subjects also performed stretching and cardiovascular exercise. A physical therapist supervised the program 2 days a week. At the end of the 6-week program, there were no injuries, pain, edema, or bleeding episodes reported. The patients significantly More >
