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.

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.

Systematic review suggests how to improve balance with specific balance exercises
Apr 13th
Balance training for rehabilitation and sports performance enhancement has increased in popularity over the past few years, yet there remains little evidence on the optimal exercise dosage and prescription for balance training. Poor balance has been associated with falls in older adults, as well as injuries in other populations. Balance training has been shown in numerous studies to improve balance, reduce falls, and reduce injuries. Unfortunately, there is little consensus on the optimal dosage of balance training in terms of volume and intensity.
A systematic review in the Journal of Strength and Conditioning Research provided a systematic review of balance training in healthy individuals. Using the PEDro scale for analyzing studies, the authors evaluated the quality and effect sizes of 16 articles involving healthy individuals. 2 types of balance training for postural stability were identified: static and dynamic balance. Static balance is defined as the ability to maintain the center of gravity within the base of support. Dynamic balance is defined as the transition from dynamic activity to a static position. The authors also identified 2 types of surfaces used in balance assessment to quantify postural stability. Stable surface assessments utilize force platforms or single-leg balance time, while unstable surface assessments utilize tilting platforms.

Balance training effective at reducing falls and improving function
Apr 6th
Fall prevention exercise programs are becoming increasingly popular. Research has demonstrated the effectiveness of strength and balance exercises in reducing the risk of falls in older adults. National organizations such as the National Council on Aging (NCOA) and the Centers for Disease Control (CDC) recommend a multi-factoral approach to fall prevention because of the numerous risk factors. Approximately 1/3 of older adults sustain falls every year in the United States, costing over $19 billion in healthcare costs.
Physical therapist researchers at Cal State University Northridge performed a study to determine the effectiveness of a balance exercise training program on strength, balance, gait, and fall risk in 23 healthy community-dwelling older adults at risk for falls. Subjects were randomly assigned to an exercise group or non-exercising control group. The exercise group performed a small group-based balance program, “A Matter of Balance” for 12 weeks, three times a week in a class setting at the PT department.
According to the authors, the exercises included balance exercises standing on foam surfaces and balance boards, as well as squats with an exercise ball. Interestingly, there was no resistive strengthening component in their description of the exercise program, although the original “A Matter of Balance” program developed at Boston More >
Training program improves throwing accuracy in baseball players
Mar 31st
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.
