ABSTRACT
STUDY DESIGN: Prospective multicenter observation. OBJECTIVE: To determine the validity of 3 commercially available at recording thoracic-lumbar-sacral orthosis (TLSO) wearing time of children with spinal cord injury (SCI) and to assess each monitor's function during daily activities. SUMMARY OF BACKGROUND DATA: A major limitation to studies assessing the effectiveness of spinal prophylactic bracing is the patient's compliance with the prescribed wearing time. Although some studies have begun to use objective compliance monitors, there is little documentation of the validity of the monitors during activities of daily life and no comparisons of available monitors. METHODS: Fifteen children with SCI who wore a TLSO for paralytic scoliosis were observed for 4 days during their rehabilitation stay. Three compliance monitors (2 temperature and 1 pressure sensitive) were mounted onto each TLSO. Time of brace wear from the monitors was compared with the wear time per day recorded in diaries. RESULTS: Observed versus monitored duration of brace wear found the HOBO (temperature sensitive) to be the most valid compliance monitor. The HOBO had the lowest average of difference and variance of difference scores. The correlation between the recorded daily entries and monitored brace wear time was also highest for the HOBO in analysis of dependent and independent scores. Bland-Altman plots showed that the pressure sensitive monitor underestimated wear time whereas the temperature monitors overestimated wear time. CONCLUSION: Compliance to prescribed wearing schedule has been a barrier to studying TLSO efficacy. All 3 monitors were found to measure TLSO compliance, but the 2 temperature monitors were more in agreement with the daily diaries. Based on its functional advantages compared with the HOBO, the StowAway TidbiT will be used to further investigate the long-term compliance of TLSO bracing in children with SCI.

OBJECTIVE: To delineate the natural history of ambulation of children and youth with spinal cord injuries (SCls). DESIGN: Retrospective single-center. PARTICIPANTS/METHODS: One hundred sixty-nine subjects who sustained SCI at 18 years of age or younger and who were followed up for at least 4 years. RESULTS: Ambulation was significantly associated with age at injury and neurological impairment but not gender. Younger age at injury was associated with greater likelihood of ambulation, higher level of ambulation, and greater duration of ambulation. Lesser severity of neurological impairment was associated with greater likelihood of ambulation. Excluding ASIA D lesions, household ambulation was noted in 5% of subjects with tetraplegic, 26% with high thoracic, 30% with low thoracic, 44% with upper lumbar, and 33% with lower lumbar lesions. Of the 7 community-level ambulators with non-ASIA D lesions, none had cervical or high thoracic injuries, 3 had low thoracic, 1 had upper lumbar, and 3 had lower lumbar lesions. Using multiple regression analysis, predictive factors for ambulation were younger age at injury, total ASIA motor score, and ASIA impairment scale score. Less cumbersome orthotics were associated with higher levels of ambulation. CONCLUSION: Ambulation status is a function of neurological impairment, age at injury, and type of orthotic.
