Another review supports proprioceptive training to prevent sports injuries
Jul 27th
It’s been documented in several studies that neuromuscular and proprioceptive exercises using unstable surfaces such as Thera-Band® Stability Trainers can reduce sports injuries. For example, Blue Thera-Band Stability Trainers were shown to reduce ankle injuries by 77% in football players at risk for ankle sprains (McHugh et al. 2007). More recently, a systematic review published in Medicine and Science and Sports and Exercise examined 7 high-quality studies on preventing sports injuries with neuromuscular/ proprioceptive training. Through a meta-analysis, the reviewers determined that neuromuscular training can effectively reduce sports injury risk, particularly those with a history of sprains.
The 7 studies they reviewed included both wobble board training (3 studies) and multi-intervention including strength training, stretching, balance training, and specific exercises (4 studies). Both balance exercise or multi-intervention exercise programs can reduce specific injuries in young athletes participating in basketball, volleyball, soccer, team handball, hockey and floorball. Specifically, balance training reduced the risk of ankle sprains by 36%, and multi-intervention training programs reduced ankle sprain risk by 50% and reduced acute knee injuries by 54%.
Thera-Band stability products can easily be incorporated in pre-season and in-season balance training programs for teams of young athletes to potentially prevent ankle and knee injuries; however, the best dosage (sets, 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.

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.

Is resistance training on unstable surfaces effective?
May 6th
Instability training, or exercising while on unstable surfaces, has become both popular and controversial. Performing resistance training on unstable surfaces such as exercise balls, balance boards, stability disks, and foam pads has been shown to reduce force output, but increase activation of “core” muscles of the trunk (Behm and Anderson 2006). No studies, however, have directly compared training outcomes on stable and unstable surfaces.
In a paper published in the Journal of Strength and Conditioning Research, researchers performed a 7 week study of resistance training exercises in 2 groups: one using unstable surfaces and the other on stable surfaces. The researchers hypothesized that the instability resistance training group would demonstrate significantly greater gains in functional testing after the program.
Forty, college-aged, healthy untrained subjects volunteered for the study. Subjects performed squats and vertical jumps, as well as 3 machine-resisted upper body exercises: lat pull down, butterfly, and bench press. Both groups performed upper body exercises at 70% of 1RM. The stable surface training group performed squats at 75% 1RM, and the instability group performed squats at 50% 1RM while balancing on wobble boards, stability discs, or a BOSU ball. The instability group also performed 4 trunk stabilization exercises on an exercise ball. Subjects More >
Physical therapy with Thera-Band products effective after surgical repair of ankle fracture
May 4th
After surgery to repair an ankle fracture, physical therapy exercise is usually prescribed; however, no randomized, controlled studies have evaluated the effectiveness of a rehabilitation program after removing the post-operative cast. A prospective, randomized, controlled trial (RCT) was published by researchers in Sweden to evaluate a standardized, but individually-suited training program supervised by a physiotherapist.
105 patients were randomly assigned to a control group or physical therapy group after an average of 6 weeks in a plaster cast. The control group received “usual care”: advice and self-directed exercise. While 76% of subjects in the control group also attended physical therapy sessions on their own, their exercises were not the standardized program of the experimental group.
The physical therapy program began 1 week after cast removal and lasted 12 weeks, with 2 sessions per week. Patients also performed exercises at home between physical therapy visits. The neuromuscular training program consisted of range of motion (ROM) exercises, strengthening, balance training, and closed-kinetic chain exercises. Patients used Thera-Band® resistance bands for ankle strengthening exercises as well as wobble board and mini-trampoline exercises for balance training.
