standing on rm and foam bases, walk across, tandem walk, step and quick turn); posture assessment (TWD, MST, chest expansion); pain (VAS); disease activity (Bath Ankylosing Spondylitis Disease Activity Index, BASDAI). Results or Clinical Course: The groups were similar in age, height, BMI. In AS group mean values were disease duration: 8.68.4 years; VAS:5.92.1, BASDAI:4.72.6; TWD:17.75.6; MST:18.62.8. The AS group had signicantly increased TWD and decreased MST than the control group had (p¼0.001). The AS group had higher sway velocity in standing on rm base, lower speed in walk across and tandem walk tests (p<.030). AS patients with decreased MST had higher sway velocity on foam base (p¼.001 r¼-0.558). AS patients with decreased MST and increased TWD had larger step width in tandem walk (p¼.017 r¼-0.433; p¼.014 r¼0.443). As disease duration prolonged, MST decreased and step width increased in AS (p¼.021 r¼-0.420, p¼.0420 r¼0.433). VAS and BASDAI had no correlation with posture and balance. Conclusions: In AS patients, restricted spine exibility impaired dynamic and static balance, prolonged disease duration impaired only the dynamic balance. We suggest assessment of posture and spine exibilty should be inevitable part of AS follow-up to prevent balance disorders.

Lim, No Disclosures: I Have No Relevant Financial Relationships to Disclose. Objective: The objective of this study was to compare the ejec- tion fraction (EF) and maximal oxygen consumption (VO 2 max) before and after completion of CR exercise and evaluate differences between EF < 30% group and EF 30-50% group. Setting: Patients with heart failure (HF) of EF 50% were included as subjects. The patients were classied into 2 groups of EF 30-50% (n ¼ 40) and EF < 30% (n ¼ 10), and all were subjected to the CR exercise program. Patients underwent hourly aerobic exercise training sessions 3 times a week for 6 weeks. Graded exercise test (GXT) and transthoracic echocardiogram (TTE) was performed on all study patients before and after completion of the CR exercise program. After 6 weeks of CR exercise, both groups were evaluated and the results were analyzed. Results or Clinical Course: Demographic data were evaluated and baseline characteristics of both group had no signicant differences. After completion of the CR exercise program, both group showed signicant increases in EF and VO 2 max. In EF 30- 50% group, EF and VO 2 max increased from 42.7% to 50.0% (p<.001), 22.7 to 26.3 (p<.001) respectively. In EF < 30% group, EF and VO 2 max increased from 22.5% to 29.9% (p<.001), 17.0 to 21.7 (p<.001) respectively. All results were statistically valid in both groups (p<.05). Conclusions: Patients with ischemic heart failure who completed a 6-week supervised CR exercise program demonstrated sustained improvements in EF and VO 2 max, measures of increased cardio- pulmonary function, regardless of initial baseline EF values. Poster 141 Pulmonary Embolism Presenting as Seizures in an Acute Inpatient Rehabilitation Unit: A Case Report. David B. Essaff, DO (University of Rochester Medical Center, Rochester, NY, Rochester, NY, United States); Kanakadurga R. Poduri, MD; Jean L. Nickels, MD. Disclosures: D. B. Essaff, No Disclosures: I Have No Relevant Financial Relationships to Disclose. Case Description: Patient A is a 30-year-old man with no signicant past medical history admitted for a pontine ischemic stroke in the setting of right vertebral artery dissection and basilar artery thrombus. Patient B is a 44-year-old man with a history of COPD admitted for a left middle cerebral artery ischemic stroke. After one week of an uncomplicated course in the inpatient reha- bilitation unit, both patients had isolated tonic-clonic seizures lasting less than 3 minutes with a short post-ictal period. Both were medically stable and participating in therapies at the time of seizures and prior vital signs were normal. Post-seizure, both had tachypnea, low-oxygen saturation, hypotension, tachycardia and diaphoresis. Patient A was somnolent but appropriately responsive. He was stabilized and transferred to an intensive care unit. Patient B was mildly obtunded and intermittently following commands, shortly after he demonstrated additional seizure activity followed by PEA arrest. Setting: Acute inpatient rehabilitation unit in a tertiary care hospital. Results or Clinical Course: Patient A had computed tomog- raphy angiogram that demonstrated right-heart strain and large saddle pulmonary emboli (PE). Patient B expired within 45 minutes of seizure onset and autopsy demonstrated multiple acute bilateral PE. Hypercoagulable work-up for both patients was negative. Discussion: The presentation of PE is often variable and nonspecic, making diagnosis challenging. Diagnosis is further complicated on rehabilitation units by the abundance of neuro- logical diseases and associated complications which include seizures. Seizure frequency in acute rehabilitation units approaches 14% and post-ictal changes in vitals and behavior may mimic or mask other pathology. While seizures represent < 1% of those presenting with PE, the high incidence of immobility on these units warrants consideration when formulating differentials for new- onset seizure. Conclusions: PE should be considered when isolated acute- onset seizures occur. Patients on the rehabilitation units are at high risk for developing venous thromboembolism and PE.
