Objective: Symptom resolution in an individual with postural orthostatic tachycardia syndrome (POTs) sustained from a mild traumatic brain injury. Clinical Features: The patient is an 14-year-old Female Soccer player who presented with a 16 month history of post-concussive symptoms she sustained from hitting her head after tripping on a soccer ball. Positive symptoms included brain fog, fatigue, irritability, lethargy, neck discomfort, difficulty with reading, concentration, difficulty with falling asleep, poor appetite and headache. On examination the following were observed: Grade 3 hypomimia with a decrease in affect. Blood pressure(BP) seated 81/60 with a heart rate of 86 bpm to a standing BP of 80/63 with heart rate of 118 bpm. Dysmetria was observed with finger-nose-finger testing, rapid pronation and supination and heel to shin on the left side. Videonystagmography (VNG) testing revealed large amplitude left beating nystagmus and poor tracking with upward pursuits. Increased latencies were noted in vertical saccades. Optokinetic responses (OKR) in the horizontal plane were variable to the right and showed elongated slow phases to the downward stimulus. Computerized dynamic posturography (CDP) revealed a 77.5% stability score with eyes open on a perturbed surface and 65.7% stability score with eyes closed on a perturbed surface. Interventions and Outcomes: A case specific intensive multi-modal neurorehabilitation protocol was designed including tilt table rehabilitation, oculomotor therapy, exertion training and vestibular therapy, over a five day period. Post-treatment findings were decreased headache intensity and frequency, normalization of affect and hypomimia, coordination of upper and lower extremities, and resolution of POTS phenomenology. VNG revealed normal vertical pursuits, saccades and OKR in horizontal and vertical planes. CDP stability scores increased to a 78.8% stability score with eyes closed on a perturbed surface. Conclusions: Intensive rehabilitation addressed signs and symptoms in a patient with POTS secondary to post concussion syndrome. The subject demonstrated significant improvements subjectively and objectively after five days of therapy. Further investigation may establish a therapeutic approach for other individuals with POTS and/or Post Concussion Syndrome.
