Spinal cord injury (SCI) rehabilitation traditionally has focused on compensation. It was believed that the human nervous system could not re-organize and improve function below the level of injury. Our own client success and recent research over the last decade have proven this to be false for many SCI patients. At Project Walk we cannot guarantee who will recover function, however, we understand and recognize symptoms that have the potential to improve function below the level of injury.
We target this potential through an intense activity-based program. This program focuses on using specific exercises that are related to the same movement patterns that occur during human development. With the same movements we are attempting to re-establish patterned neural activity in the central nervous system. These same movement patterns are replicated by our clients with the assistance of our highly trained SCI Recovery Specialists. Our SCI Specialists have been trained to respond to the cues that each client’s nervous system provides and, with proper stimulus, help it to re-organize.
Our unique exercises and highly trained staff also believe that the use of antispasmodics and other prescriptions associated with traditional SCI treatment may hinder the chance of recovery. Many of our clients have found that the elimination of medications, under their doctor’s supervision, improves their quality of life and helps them to progress in their recovery. As a result of increased activity and less medication, our clients have improved their overall health and quality of life.
The Dardzinski Method
The Dardzinski Method is a theory based upon more than a decade of experience working with SCI as well as current scientific research. Research on activity and how it relates to SCI has progressed rapidly in the last few years. After SCI, the body begins to breakdown physiologically. This is partially caused by reducing the effect of gravity on the body and through exercise we are attempting to reverse this breakdown. The effects of exercise on someone with a spinal cord injury are similar to that of able-bodied individuals.1 Passive exercise alone has been shown to decrease physiological breakdown after SCI, but we believe weight bearing exercise may have an even greater effect.2 This type of exercise is what the human body was designed to do; standing, walking, lifting, etc.
Many of the exercises we use are based on recreating patterned neural activity. This is the process by which it is thought the central nervous system develops its structure and function in the growing human being. The continuous repetition of movement may help to create this neural pattern in the brain and spinal cord. 3 Research has shown that relearning a specific motor task may be highly dependent on the repetitive stimuli provided when input from the brain is limited.
Brain Derived Neurotrophic Factor (BDNF) may also be a factor in recovering function. Research suggests that through exercise BDNF levels can be increased and could result in a stimulation of stepping and an increase in axonal sprouting.5-7 In short, the increase in BDNF through exercise may assist in reorganization of the nervous system.
