Balance exercises for chronic ankle sprains effective

Dr. Phil Page — Tue, 31 Aug 2010 12:12:58 +0000

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 control group. The authors reported improvements in gait kinematics, specifically the coupling of rearfoot and lower leg motion during walking. The researchers noted that the changes in gait kinematics following the exercise program were likely due to changes in sensorimotor function resulting from the 4- week balance training program, particularly since ligamentous laxity did not change.

In summary, a 4-week progressive balance training program implementing hops and single-leg balance exercises with Thera-Band Stability Trainers can help improve balance, function, and kinematics in patients with chronic ankle instability.

Neuromuscular training program reduces injury and improves performance in female athletes

Dr. Phil Page — Tue, 20 Jul 2010 13:39:30 +0000

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.

Researchers encourage proprioceptive exercises for shoulder rehabilitation

Dr. Phil Page — Tue, 27 Apr 2010 10:53:09 +0000

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.

Training program improves throwing accuracy in baseball players

Dr. Phil Page — Wed, 31 Mar 2010 14:44:50 +0000

Core training is thought to be important to improve functional sport activities, particularly those involving force transfer through the abdominals and back, into the extremities. For example, much of the strength and power required to throw a baseball comes from the force transmitted through the core from the legs. This is an example of the ‘kinetic chain,” where different parts of the body are interconnected and all contribute in some way to performing a functional activity.

Few studies have investigated the effects of core training on functional performance. Athletic training researchers investigated the effects of a shoulder training program with and without core stability exercises. 19 baseball players were randomly assigned to an open and closed-chain exercise program, or the same program with additional core training. 15 healthy age-matched non athletes were used as a quasi-control group. Each subject was tested for throwing accuracy, core stability, and proprioception before and after the 6-week program.

Both groups performed a shoulder training program that included free weights, closed-chain balance board, step-up, and exercise ball exercises, as well as plyometric ball tosses. The core training group also performed stabilization exercises such as the dead bug, sit-up, bridge, wall slides, and sitting on an exercise ball.

After the training program, both groups improved in function, stability and proprioception. The addition of core stability exercises did not result in significantly different outcomes. It’s possible that the core stability program may not have been functionally challenging to the core. Relatively static exercises were used in the core training program, rather than sports specific training.

Thera-Band® products such as exercise balls, soft weights, and balance boards can be used successfully in a baseball training program to improve throwing accuracy.
