Setting: Academic Veterans Affairs hospital. Participants: All patients underwent electrodiagnostic testing and 21 enrolled. Inclusion criteria were age 18-90 years and with one of the following: distal motor latency, 4.2 ms; motor ampli- tude, 3.5 mA; antidromic distal sensory latency, 3.5 ms; anti- dromic sensory amplitude, 12 mA; antidromic median to ulnar distal sensory latency difference, 0.4 ms. Exclusion criteria were osteoporosis; prior CTS surgery; allergy to local anesthetic, cortico- steroid, or ultrasound gel. Interventions: Carpal tunnel injections were performed with 0.50 mL (20 mg) methylprednisolone and 0.50 mL of 1% lidocaine with a 25-gauge 1.5-in. needle, by using blind or ultrasound guid- ance. Blind injections were performed just ulnar to the palmaris longus tendon, inline with the ring finger. Ultrasound-guided injec- tions were performed by using a long-axis medial-to-lateral ap- proach, as described by Smith et al. 2008. Main Outcome Measures: VAS and Global Symptom Score at 2, 4, and 8 weeks. Results: There was a significant decrease in VAS in the ultra- sound-guided group from baseline to 2 (P.023) weeks and 8 weeks (P.028). Four weeks trended toward significance (P.146). There was a trend toward significance in improvement of the weakness measure of the Global Symptom Score between the 2 groups. There were no adverse reactions reported in either group. Conclusions: Ultrasound-guided carpal tunnel injections are more effective than blind at reducing pain at 2 and 8 weeks, and may improve subjective weakness. Poster 51 Patient Communication of Community Adaptations, High-kneel Mobility, in Spinal Muscular Atrophy Type 3 (Kugelberg-Welander Disease or Juvenile Spinal Muscular Atrophy): A Case Report. Courtney Toomey, MD (Sinai Hospital, Baltimore, MD, United States); Henry S. York, MD. Disclosures: C. Toomey, none. Patients or Programs: A 45-year-old man with spinal muscular atrophy (SMA) type 3. Program Description: The patient was diagnosed with SMA type 3 at age 3 years, required crutches at age 13 years, last walked at age 18 years, and then adapted his mobility and activities of daily living (ADL) tasks to a high-kneel position. He was admitted to an acute hospital for new onset limb weakness with head drop. A workup was significant for hypokalemia and epigastric pain (which resolved with Carafate); the weakness was thought to be debility secondary to a metabolic disturbance. He was transferred to our acute rehabilitation facility, where results of an examination were significant for calluses overlying his patellae, right medial hamstring pain, and severe limb atrophy, with preserved distal strength. By using his excellent artistic ability, he illustrated his home environment and high-kneel transfer techniques, which provided an illustrative guide for his therapy team on high-kneel positioning for mobility. Setting: A free-standing rehabilitation hospital. Results: After a month of inpatient rehabilitation, and assistance from his illustrations, he returned to his baseline level of function, performing mobility and ADLs independently while in a high-kneel position. Discussion: SMA is characterized by degeneration of anterior horn cells in the spinal cord and motor nuclei in the brainstem due to a deficiency of a motor neuron protein, SMN, secondary to a faulty gene on chromosome 5. Type 3 is milder and diagnosed after 18 months, typically before age 3 years. Walking is usually maintained through adolescence; a wheelchair is often required later in life. Weakness is severe in proximal muscles, including shoulders, hips, thighs, upper back, and the muscles of respira- tion. Spinal curvature often develops, and lifespan is considered normal. This patient’s artistic talents enabled him to communi- cate his unique adaptive techniques, and ultimately allowed him to return to his baseline level of function in the community. Conclusions: The high-kneel position, as uniquely demon- strated by this patient with SMA type 3, can be an effective means for maintaining independence with mobility and ADLs. Poster 52 Predictive Validity of the Westhaven Multidimensional Pain Inventory. William L. Parkinson, PhD (McMaster University, Hamil- ton, ON, Canada); Jonathan Adachi, MD, Dinesh A. Kumbhare, MD, Anita Thompson, BA. Disclosures: W. L. Parkinson, none. Objective: This study was conducted to investigate the predictive type, criterion-related validity of the Multidimensional Pain Inven- tory (MPI) for the persistence of pain after motor vehicle collisions. Design: A measurement evaluation study. Setting: An interdisciplinary rehabilitation clinic in a teaching hospital in Hamilton, Ontario, Canada. Participants: Eleven women and 8 men with grade 1 or grade 2 whiplash-associated disorders. Interventions: The third revision of the MPI (MPI-3) was admin- istered at 2 weeks, and 6 months after motor vehicle collisions. The subject scores on the 9 MPI subscales were entered into the analyses, including (1) Pain Severity, (2) Interference in Activities, (3) Life Control, (4) Affective Distress, (5) General Activity, (6) Support by Significant Others; and the Behavior of Significant Others, including (7) Punishing Responses, (8) Solicitous Responses (reinforcement of illness role), and (9) Distracting Responses. Main Outcome Measures: Descriptive statistics were used to compare the sample with pain patient norms. Multivariate logistic regression was used to test the independent contribution of each MPI-3 construct in the acute stage, against Pain Severity, and pain change scores at 6 months. Results: At 6 months, in comparison with chronic pain norms, sample means were at the 26th percentile for Pain Severity, 41st percentile for Affective Distress, 48th percentile for the Dysfunc- tional scale, and 56th percentile for Interpersonal Distress. There was a trend toward predictive validity between the MPI-3 at 2 weeks and Pain Severity at 6 months (r0.85, P.07). The MPI-3 at 2 weeks was highly predictive of the changes in Pain Severity over time (r0.94, P.01). A 6-month pain improvement was positively correlated with acute stage Activity (P.05) and use of Distraction (P.03). No other social variable (Punishment, Solicitous Re- sponses, Support) was correlated with improvement. Conclusions: (1) The findings provide preliminary support for the predictive validity of the MPI-3 for chronic pain development, S194 PRESENTATIONS

Poster 53Therapeutic Intensity and Functional Gains DuringInpatient Rehabilitation.Hua Wang (Kaiser Foundation Rehabilitation Center,Vallejo, CA, United States); Michelle Camicia, Murali K.Mannava, Elizabeth Sandel, MD, Steve Sidney, JoeTerdiman, MD, PhD.

Disclosures: H. Wang, none.Objective: To study the effects of therapeutic intensity on func-tional gains.Design: A retrospective cohort study.Setting: An inpatient rehabilitation hospital (IRH) in northernCalifornia.Participants: 592 patients discharged from the IRH in 2007.Interventions: The average number of minutes of rehabilitationtherapy per day, including physical therapy (PT), occupation ther-apy (OT), speech therapy (ST), and total treatment.Main Outcome Measures: Functional gains measured byFunctional Independence Measure (FIM), including motor, cogni-tion, and total scores.Results: The study sample had a mean age of 60.5 years, and was41.9% women and 64.9% white. Two-thirds of patients had adiagnosis of stroke; 89.7% had one or more comorbid conditions.The median IRH stay was 20 days. The mean total therapy time was185.3 min/d (PT, 114.1 min/d; OT, 42.8 min/d; and ST, 32.3min/d). The mean total functional gain was 25.3 (motor, 18.4;cognition, 5.7). The patients who received total therapy of fewerthan 3 hours per day showed significantly lower total functionalgain than those treated for 3 hours or longer. However, there was nosignificant difference in total functional gain between patientstreated 3-3.5 hours and more than 3.5 hours per day. Intensities ofOT, PT, and ST also were significantly associated with correspond-ing motor and cognition functional gains. Multiple linear regressionmodels showed that young age, living alone before hospitalization,lower comorbidity scores, earlier admission to IRH, medical treat-ment, and longer IRH stay were independent predictors for func-tional improvement.Conclusions: The study demonstrated a significant effect of ther-apeutic intensity on functional gains during an IRH stay and evi-dence of treatment intensity thresholds for optimal functional out-comes.

Poster 54Barriers to Home Discharge After Acute InpatientRehabilitation in Patients With Parkinson Disease: ARetrospective Analysis.Kareen A. Velez, MD (Tufts Medical Center, Boston, MA,United States); Deniz Ozel, MD, Ajay Patel, MD.

Disclosures: K. A. Velez, none.Objective: To identify the main barriers to home discharge inpatients with Parkinson disease (PD) related deficits admitted to anacute inpatient rehabilitation facility (IRF).Design: Retrospective medical chart review.Setting: Free-standing IRF.

Participants: Patients with PD admitted to an IRF from January 1,2009 to December 31, 2009.Interventions: Multidisciplinary movement disorders program.Main Outcome Measures: Length of stay (LOS), admission anddischarge functional independence measure (FIM) scores, dischargedestination, and the need for caregiver assistance. Additional datacollected included age, gender, reason for admission, and Mini-MentalState Examination (MMSE) scores on admission. Barriers to homedischarge were identified in patients who were unable to return home.Results: Of 71 subjects admitted to an IRF from January 1, 2009 toDecember 31, 2009 for multidisciplinary movement disorders pro-gram, 6 patients had at least 1 readmission. The most commonreason for admission included falls secondary to gait disturbancesand changes in mental status. Three patients had an interruptedLOS due to medical complications. Of the remaining 62 patientswith ages that ranged from 67-86 years, 15 were unable to bedischarged home (28%). The main barrier to home discharge wascognitive impairments (59%), followed by lack of caregiver assis-tance (41%). The mean LOS in cognitively impaired subjects was10�6.5, with a mean MMSE on admission of 19.6/30�6.1. Nomale to female difference was noted.Conclusions: Patients with PD can manifest a variety of complexmedical and functional deficits that affect their independence andquality of life. Results of our study suggest that cognition plays a keyrole in maintaining function and independence in geriatric patientswith PD-related deficits admitted to IRF. It is also directly correlatedto home discharge rates, independent of MMSE scores on admissionor LOS. Hence, movement disorder rehabilitation programs arecrucial in ensuring that this population can return home safely afterinpatient rehabilitation program.

Disclosures: C. E. Daves, none.Patients or Programs: A 28-year-old El Salvadorian womanwith no significant medical history.Program Description: A 28-year-old El Salvadorian womanwith acute motor axonal neuropathy (AMAN).Setting: Acute rehabilitation facility.Results: The patient made slow gains in strength, was decannu-lated, and began oral feedings. She was discharged home after 44days of intensive inpatient rehabilitation, ambulating 150 ft with arolling walker with minimal assistance and bilateral ankle footorthoses. At follow-up, she displayed improved facial movementand strength, and was ambulating 200 ft independently with arolling walker.Discussion: The patient was admitted to the hospital with bilat-eral lower extremity weakness, which ascended to involve bothupper extremities and her face. She denied any pain, numbness,paresthesias, recent illnesses or travel, or family history of neuro-muscular disorders. However, she had emigrated from El Salvador 3years earlier. She was subsequently intubated for ventilatory failure.A lumbar puncture was normal. She was diagnosed clinically withGuillain-Barré syndrome and received a 5-day course of IVIG. Atracheostomy was performed, and a percutaneous gastrostomy tubewas placed. She slowly regained motor function and was weaned off
