Physiotherapists also play a significant role in rehabilitation after a brain injury. In the case of a traumatic brain injury (TBIs), physiotherapy treatment during the post-acute phase may include: sensory stimulation, serial casting and splinting, fitness and aerobic training, and functional training. Sensory stimulation refers to regaining sensory perception through the use of modalities. There is no evidence to support the efficacy of this intervention. Serial casting and splinting are often used to reduce soft tissue contractures and muscle tone. Evidence based research reveals that serial casting can be used to increase passive range of motion (PROM) and decrease spasticity. Studies also report that fitness and aerobic training will increase cardiovascular fitness; however the benefits will not be transferred to the functional level. Functional training may also be used to treat patients with TBIs. To date, no studies supports the efficacy of sit to stand training, arm ability training and body weight support systems (BWS). Overall, studies suggest that patients with TBIs who participate in more intense rehabilitation programs will see greater benefits in functional skills. More research is required to better understand the efficacy of the treatments mentioned above.
