Long-Term Functional Outcomes in Military Service Members and Veterans After Traumatic Brain Injury/Polytrauma Inpatient Rehabilitation.

OBJECTIVE: To determine the effect of the established polytrauma/traumatic brain injury (TBI) infrastructure on immediate posttreatment functional gains, the long-term sustainability of any gains, and participation-related community reintegration outcomes in a baseline cohort of patients 8 years postadmission. DESIGN: Retrospective review and prospective repeated measures of an inception cohort. SETTING: Polytrauma rehabilitation center (PRC). PARTICIPANTS: Patients consecutively admitted to the PRC inpatient rehabilitation unit during its first full fiscal year, 2006 (N=44). INTERVENTIONS: The PRC infrastructure and formalized rehabilitation for polytrauma/TBI. MAIN OUTCOME MEASURES: FIM scores at admission, discharge, 3 months, and 8 years postdischarge; participation-related socioeconomic factors reflecting community reintegration 8 years after admission. RESULTS: Functional gains were statistically significantly increased from admission to discharge. Improvements were maintained at both 3 months postdischarge and 8 years postdischarge. The socioeconomic data collected at 8-year follow-up showed >50% either competitively employed or continuing their education and 100% living in a noninstitutionalized setting. CONCLUSIONS: This study addresses a concern regarding the long-term functional outcomes of rehabilitation patients treated by the established infrastructure of the Polytrauma System of Care inpatient rehabilitation centers. The results suggest that polytrauma/TBI rehabilitation care using a comprehensive, integrated approach is effective and durable in achieving functional gains and successful community reintegration within our initial PRC cohort. Follow-up of subsequent fiscal year cohorts would add to the validity of these outcome findings.

Unexpected recovery after robotic locomotor training at physiologic stepping speed: a single-case design.

OBJECTIVES: To investigate the effect of walking speed on the emergence of locomotor electromyogram (EMG) patterns in an individual with chronic incomplete spinal cord injury (SCI), and to determine whether central pattern generator activity during robotic locomotor training (RLT) transfers to volitional EMG activity during overground walking. DESIGN: Single-case (B-A-B; experimental treatment-withdrawal-experimental treatment) design. SETTING: Freestanding rehabilitation research center. PARTICIPANT: A 50-year-old man who was nonambulatory for 16 months after incomplete SCI (sub-T11). INTERVENTIONS: The participant completed two 6-week blocks of RLT, training 4 times per week for 30 minutes per session at walking speeds up to 5km/h (1.4m/s) over continuous bouts lasting up to 17 minutes. MAIN OUTCOME MEASURES: Surface EMG was recorded weekly during RLT and overground walking. The Walking Index for Spinal Cord Injury (WISCI-II) was assessed daily during training blocks. RESULTS: During week 4, reciprocal, patterned EMG emerged during RLT. EMG amplitude modulation revealed a curvilinear relationship over the range of walking speeds from 1.5 to 5km/h (1.4m/s). Functionally, the participant improved from being nonambulatory (WISCI-II 1/20), to walking overground with reciprocal stepping using knee-ankle-foot orthoses and a walker (WISCI-II 9/20). EMG was also observed during overground walking. These functional gains were maintained greater than 4 years after locomotor training (LT). CONCLUSIONS: Here we report an unexpected course of locomotor recovery in an individual with chronic incomplete SCI. Through RLT at physiologic walking speeds, it was possible to activate the central pattern generator even 16 months postinjury. Further, to a certain degree, improvements from RLT transferred to overground walking. Our results suggest that LT-induced changes affect the central pattern generator and allow supraspinal inputs to engage residual spinal pathways.

Changes in stroke rehabilitation outcomes after the implementation of Japan's long-term care insurance system: a hospital-based study.

OBJECTIVE: To explore the changes in stroke rehabilitation outcomes after the introduction of Japan's long-term care insurance (LTCI) system. DESIGN: Stroke patients discharged during a 3-yr period before and after the implementation of LTCI were compared (before-LTCI vs. after-LTCI). Outcome measures included onset to admission interval, length of stay, and correlation between discharge site and functional level at discharge. RESULTS: A total of 201 patients in the before-LTCI group and 252 patients in the after-LTCI group were eligible for the study. Shorter mean length of stay (P < 0.01) and higher rates of discharge to a rehabilitation facility (P < 0.01) were found in the after-LTCI group. Logistic regression analysis revealed that the patients with higher activities of daily living scores or ambulatory status at discharge were more likely to be discharged to home after inpatient rehabilitation in both groups (P < 0.01). The rate of discharge to home was similar in both groups. CONCLUSIONS: Within this rehabilitation hospital's experience, the mean length of stay was reduced after the implementation of the LTCI. Although it was one of the primary goals of the LTCI, the rate of discharge to home did not significantly increase. Further evaluation and modification of the LTCI and more efforts to improve a patient's activities of daily living and ambulatory status at discharge will be necessary to promote in-home care in Japan.
