Progressive muscle relaxation, meditation, and mental practice-based interventions for the treatment of tremor after traumatic brain injury.

Background and purpose: Individuals post traumatic brain injury (TBI) are likely to experience cognitive, sensory, and motor impairments. Tremor is a common movement disorder that can affect this patient population. The purpose of this case report was to describe the effects that progressive muscle relaxation, meditation, and mental practice-based interventions have on the treatment of chronic right upper extremity tremor in a patient post-TBI.

Case description: A 47-year-old male with a traumatic brain injury presented with a resting and postural tremor of the right wrist flexors and deficits in cognition, sensation, proprioception, balance, and motor function. The patient's primary goal for therapy was to decrease the tremor to improve his quality of life and ability to perform activities of daily living.

Methods: Progressive muscle relaxation, breath-focused meditation, and mental practice-based intervention were administered to the patient. Active range of motion activities occurred during weekly in-person sessions and daily practice occurred at home.

Results: The patient demonstrated improvements in quality of life, self-ratings of tremor severity, ratings of tremor impact on ADL's, gross motor object manipulation, frequency of tremor via surface electromyography, and visual inspection of a spirograph.

Conclusion: A combination of progressive muscle relaxation, meditation, and mental practice-based interventions appeared to positively impact tremor across physical and psychosocial domains in a patient with a chronic tremor. Further investigation is needed to verify these findings.
