Balance training using unstable surfaces such as Thera-Band Stability Trainers and Rocker / Wobble Boards continue to increase in popularity both in rehabilitation and sports performance. In addition, balance training has been shown to be beneficial in preventing injuries across the lifespan, from athletes to older adults.
German researchers published a systematic review of the efficacy of balance training for neuromuscular control and performance enhancement in the Journal of Athletic Training. 20 randomized clinical trials of balance training met their inclusion criteria for the review. As with many systematic reviews, the authors noted a lack of methodological quality and conflicting findings between studies. Nonetheless, they were able to make some conclusions:
- Balance training is effective at improving static postural sway and dynamic balance in both athletes and non-athletes.
- Balance exercises are recommended for postural and neuromuscular improvements, particularly for rehabilitation and preventive purposes.
- To improve strength, jumping or sports performance other interventions such as strength training are more effective than balance training.
- Longer balance training durations of 6 to 12 weeks seem more effective than shorter (4 week) durations.
The authors concluded that further research with higher methodological quality More >
Wobble board exercises can reduce ankle injuries in soccer players
Jan 18th
Neuromuscular training has long been performed in Europe as part of sports training and injury prevention. Neuromuscular training involves progressive balance training using unstable surfaces such as Thera-Band® Stability Trainers, Stability Discs, and Balance Boards. Several studies have reported that proprioceptive exercises and training reduce injuries in athletes.
Researchers in Hungary evaluated the effects of a 20-month proprioceptive training program in 10 female handball players. Their ankle proprioception was compared to a control group of 10 competitive athletes. The program included static and dynamic balance exercises using wobble boards. At the end of 20 months, the training group had completed 780 hours of the proprioceptive exercise. Their ankle proprioception, measured by ankle joint position sense, was significantly better compared to the control group. In addition, the training group experienced a 50% reduction in injuries. Proprioceptive training progression including Thera-Band Wobble Boards can improve ankle proprioception and may decrease ankle injury rates in contact sports.

Balance exercises for chronic ankle sprains effective
Aug 31st
Chronic ankle sprains have been attributed to poor sensorimotor control, resulting in “functional ankle instability.” First described in the 1960’s by Freeman and Wyke, functional ankle instability has been postulated to result from a lack of proprioceptive information from the ankle due to “deafferentation.” Functional ankle instability is associated with chronic ankle sprains; patients with functional ankle instability may have normal strength and ligament structure, yet continue to suffer ankles sprains. Progressive balance exercise programs have been shown effective at reducing functional instability and recurring ankle sprains. Sensorimotor training programs for ankle instability often include balance exercises that use foam pads such as Thera-Band® Stability Trainers.
Researchers at the University of Kentucky developed a progressive balance training program for patients with chronic ankle instability. The program lasted 4 weeks and focused on dynamic balance stabilization in single-leg stance. Exercises included progressions in hops and single-leg balance using foam pads and 6-pound medicine balls. The results of their first study, published in Medicine and Science in Sports and Exercise in 2008, found that their program significantly improved function and postural control in chronic ankle sprain patients. In their more recent study, 29 subjects with chronic ankle instability were randomly assigned to either an exercise group or 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.

Researchers encourage proprioceptive exercises for shoulder rehabilitation
Apr 27th
Proprioceptive exercises are commonly prescribed for lower extremity rehabilitation. More recently, sensorimotor (SMT) proprioceptive exercises have been used for shoulder rehabilitation. It’s thought that shoulder injury (in particular, shoulder instability) is related to proprioceptive deficits. Researchers speculate that deafferentation (loss of sensory information) from the mechanoreceptors of the shoulder joint capsule and altered proprioceptive information create these sensorimotor deficits (Lephart et al. 1997; Tibone et al. 1997)
A review paper in Athletic Training and Sports Healthcare discussed the adaptations of the sensorimotor system following shoulder rehabilitation. The authors used the PEDro system for inclusion criteria to review 23 articles. The most common techniques the paper reviewed included:
- Joint repositioning
- Closed-kinetic chain exercises
- Proprioceptive Neuromuscular Facilitation (PNF)
- Plyometrics
- Joint Perturbations
- Activation of muscle through elastic tubing, free weights or oscillation
The authors concluded that sensorimotor rehabilitation after shoulder injury is crucial, and that the sensorimotor system is, in fact, trainable. A proprioceptive and sensorimotor training program including Thera-Band® elastic bands and tubing, FlexBar® Oscillation, and closed-kinetic shoulder exercises with Stability Trainers should be included as part of a shoulder rehabilitation or prevention program.
