Reactive Balance

The biggest goal when working with people who demonstrate unstable gait or fear of falling is to help them learn how to control their center of gravity. Traditionally the framework for interventions was viewed as incorporating static or dynamic balance interventions. When determining interventions to improve balance and stability, you can now begin to become more detailed in your thought processes. You can incorporate anticipatory adjustments in your balance intervention strategy. You can include reactive balance intervention strategies. Reactive balance is different than anticipatory adjustments because the patient is not aware and cannot plan for the upcoming situation. The patient's body has to immediately take action and react without any planning. The outwardly observed goal is for the patient to defy gravity and not fall.

Indication

Anyone who is at risk of falling is a candidate for reactive balance intervention strategies.

Clinical Presentation

Clinical presentation includes information you receive from the patient. If you consider patient reported outcome measures, then you will appreciate learning the Activities-Specific Balance Confidence Scale. Confidence in balance and fear of falling are predictive of future falls. A score < 67% indicates an increased risk of falling.

A patient who needs interventions that include reactive balance will share stories of having difficulty feeling safe walking outdoors. Will report holding onto furniture or walls while walking. Will mention feeling unsteady. Will probably mention slips, trips, near falls or falls.

The Berg Balance Scale is a performance measurement tool that can be used to determine if a patient is at risk of falls.

As you observe your patient, you may notice that they demonstrate some gait characteristics that could be interpreted as compensating for unsteadiness. Patients will demonstrate a slower gait speed. Patients will decrease their step length. Patients will have an increased step width. You may notice that your patient does not fully pick up their feet as they ambulate.

Resources

This is a study that includes a small n value for a randomized controlled trial comparing conventional balance training on a surface that is unstable but is targeted to have postural sway responses mainly involving the ankle joint (ankle strategies) to reactive balance training where the support surface is moved underneath the feet.

One image in the above study really connected with me to help better understand what is meant by reactive balance training. As you can see, the support surface is moved underneath the person and the person has to respond to that perturbation.

Reactive Balance Training

When we begin talking about reactive balance intervention strategies, these types of strategies require some equipment in order to create a situation where the ground is moving under the feet. Let me first share a few of my own videos on various ways to provide reactive balance interventions.

This next video should not be considered an endorsement. Creating reactive balance intervention strategies is fairly new in the physiotherapy industry. The best way to get ideas and to understand how to create such an intervention is to look within the market for examples. I consider this next product a reactive balance intervention because the physiotherapist determines the type of perturbation and the speed. As you could see in the above video of myself providing perturbations, I am not able to standardize or necessarily easily adjust the type or amount of perturbation I am able to provide. This particular piece of equipment allows the clinician to adjust the intervention parameters for the patient.

This next set of videos gives you another visual of the ground moving under the feet for a patient response.
