Effects of a Combined Treatment for Sound Error Correction for Childhood Apraxia of Speech
Research Posters Setting: In-patient rehabilitation with pre-assessment before randomization. Blinded pre- and post- assessments. Participants: Subjects (nZ34), were minimum two years post injury with grade C or D on the American Spinal Injury Association (ASIA) Impairment Scale were selected. Interventions: Intervention (I): BWSLT for 60 days, 1.5 hours per day, 5 days per week over six months. Control (C): usual care. Main Outcome Measure(s): Lower extremity motor score (LEMS), Bergs balance scale (BBS), Ouality of life (SF-36) and pain (VAS). Results: In both I and C groups, 73% had some gait function and 6/15 and 7/19, respectively, were ASIA grade C with the rest being grade D. The I-group showed significant improvement in LEMS, mean change 2.27 (CI 0.75, 3.78), pZ0.006 compared to no change in the C-group. BBS improved in the I-group [1.79 (CI 0.92, 3.49), pZ0.04] with no change in the control group. The I-group reported slightly increased pain during activities 0.73 (CI 0.02, 1.44), pZ0.04 compared to that observed in the Cgroup [-0.26 (-1.03, 0.50)], pZ0.48. Subscore Physical Function in QoL improved in both groups, stronger in the I-group [6.92 (CI 0.93, 12.91)], pZ0.03. No adverse events were reported except minor issues (superficial wounds) in the lower extremities. Conclusion/Discussion: Overall, manual BWSLT improved lower extremity strength and self-reported physical functioning and maintained balance. Results should be interpreted with caution due to small sample size. Findings will add knowledge about the usefulness of BWSLT in subjects with incomplete SCI.

Research Poster 296834 Effects of a Combined Treatment for Sound Error Correction for Childhood Apraxia of Speech Jui-ching Liu (Changhua Christian Hospital) Research Objectives: To examine the effects of a combined treatment approach that included integral stimulation paired with minimal contrast treatment on children with childhood apraxia of speech (CAS). Design: A multiple-baseline design across behaviors was used for this study. Setting: Hospital. Participants: Inclusion criteria were: (a) a diagnosis of CAS, (b) normal receptive vocabulary, (c) normal hearing acuity, (d) normal orofacial structure and function, and (d) no known other developmental or genetic diagnosis. Four children (3 males and 1 female) ranging in age from 4;5 (years; months) to 6;2 at the beginning of the treatment were identified. Interventions: Each sound was targeted in four levels: minimal pair production; production in single words; production in phrases; and production in sentences. An 80% accuracy criterion was required to move from word to phrase to sentence level. A new error sound was introduced, once an error sound moved to sentence level. Main Outcome Measure(s): The effects of this combined approach were assessed on four outcome measures: (a) phonetic inventory, (b) percentage consonants correct (PCC), (c) the consonant substitute inconsistency percentage (CSIP), and (d) the inconsistency severity percentage (ISP). Results: The combined treatment yielded an average of 70% increase in PCC. The participants gained 14 phones, on average, with individual increments ranging from 13 to 15 phones. CSIP decreased an average of 4.4%. All children made considerable decreases in ISP with an average of 21%. Conclusion/Discussion: The results indicate that integral stimulation paired with minimal contrast treatment may increase speech sound inventory, phonemic accuracy, and consistency of both treated and untreated words for children with CAS. Future studies might investigate the importance of other motor learning principles combined with cognitivelinguistic approaches in more depth.

Research Poster 313544 Effects of a Week-Long Intense Rehabilitation Camp on Walking Outcomes of Stroke Individuals in Jamaica Andrew Nauss (Arcadia University), Rachel Jordon, Gabe Rocco, Brooke Riley, Bethany Wolf, Rochelle Mendonca, Michelle Johnson, Shailesh Kantak Research Objectives: The purpose of this retrospective analysis was to investigate the effects of a week-long, intense and structured rehabilitation camp on gait speed in patients with stroke. We further investigated if baseline walking performance, categorized by pre-intervention gait speed (household ambulators (< 0.4 m/s); limited community ambulators (0.4-0.8 m/s); community ambulators (>0.8 m/s)) determined the amount of improvement in gait speed post-intervention. Design: Pre-post evaluation after a week intensive rehabilitation. Setting: Community clinic in rural Jamaica, West Indies. Participants: 60 patients with subacute and chronic stroke. Interventions: Patients participated in intense rehabilitation program involving upper and lower extremity functional activities including gait training for 7 hours/day for a week. Main Outcome Measure(s): Gait speed was measured before and after the program using the 10 Meter Walk Test. Secondary measures were Timed Up and Go, 6 Minute Walk Test for distance, Berg Balance Test, and Functional Gait Assessment. Results: As a group, participants improved their walking speed with an average increase of 0.18 m/s., an improvement greater than the MCID (0.16 m/s). However, the changes in gait speed were not equal across the functional groups (ANOVA: FZ6.715, pZ.0024). Post hoc pairwise t-tests revealed significant improvements only for the household ambulators and community ambulators (tZ-3.58, p < 0.001). Further, the number of participants passing the MCID differed between household and community ambulators (X2Z4.737; pZ0.0295). Conclusion/Discussion: An intense week-long therapeutic camp can provide clinically-important improvements in gait speed in patients poststroke, Greater improvements are seen in patients with an initial gait speed greater than 0.8 m/s than those with gait speed less than 0.4 m/s.

Research Poster 304415 Effects of Aerobic Exercise Training on Fitness and Walking in Ambulatory Adults with Incomplete SCI Nicole DiPiro (Medical University of South Carolina) Research Objectives: To investigate the effects of a non-task specific, progressive aerobic exercise training (AET) intervention on fitness and walking-related outcomes in ambulatory adults with chronic incomplete SCI. Design: Single group, pretest-posttest. Setting: Medical university rehabilitation research center. Participants: Eligibility criteria: (1) Age 18-75; (2) First time, motorincomplete SCI (AIS C-D, traumatic or vascular origin); (3) Chronic SCI, >6 months post-injury; (4) Ability to walk 10 meters independently, with or without an assistive device; (5) Self-selected walking speed > 0.1 m/s and < 1.15 m/s; (6) Medically stable. Ten individuals (50% female; 57.949.33 years old; 11.119.66 years post-injury) met the criteria and volunteered for the intervention. Interventions: Participants completed voluntary, progressive, moderate-tovigorous intensity AET on a recumbent stepper 3 days/week for 6 weeks. Main Outcome Measure(s): Aerobic capacity (VO2peak) and self-selected overground walking speed (OGWS). Secondary outcome measures
