RESUMEN
STUDY DESIGN: Retrospective statistical analysis of database. OBJECTIVES: Prediction of the Spinal Cord Independence Measure version III Total Score (SCIM-TS) at 6 months after injury based on physical findings at 1 month after injury is an important index for rehabilitation approach in the recovery phase. SETTING: Spinal Injuries Center, Fukuoka, Japan. METHODS: The study participants were selected from patients with traumatic spinal cord injuries who were registered in the Japan Single Center Study for Spinal Cord Injury Data Base (JSSCI-DB) of the Japan Spinal Injuries Center specializing in spine and spinal cord injuries. Of the 534 participants registered with the JSSCI-DB between January 2012 and October 2018, we retrospectively extracted 137 participants for 6 months after injury, and these participants were included in this study. RESULTS: According to multiple regression analysis, SCIM-TS at 6 months after injury could be predicted based on only six variables, i.e., age at injury, three key muscles (C6 wrist extensors, C8 finger flexors, and L3 knee extensors), and two mobility assessments (WISCI and SCIM-item13) (Adjusted R-Squared: 0.83). These six independent variables were significant factors reflecting SCIM-TS at 6 months. CONCLUSIONS: In rehabilitation after traumatic spinal cord injuries, a simple and reliable prognostic model can help accurately predict the achievable activity of daily living competency to set a goal. In addition, if the procedure is simple, evaluation can be completed in a short period of time, and the physical burden on both treating staff and patients can be reduced.

STUDY DESIGN: Descriptive study. OBJECTIVE: To demonstrate Euro Quality of Life 5-dimensional 5-level (EQ-5D-5L) by severity level at the acute stage and discharge in patients with traumatic spinal cord injury (SCI). SETTING: Spinal Injuries Center, Fukuoka, Japan. METHODS: Patients with traumatic SCI who completed the EQ-5D-5L instrument at the acute stage and discharge were divided into four groups according to severity (severity group G1; C1-C4 ASIA Impairment Scale (AIS) A, B, and C, G2; C5-C8 AIS A, B, and C, G3; T1-S5 AIS A, B, and C, G4; all AIS D). All data were extracted from the Japan single-center study for spinal cord injury database (JSSCI-DB). RESULTS: Data were collected from 139 individuals at the acute stage and 164 individuals at discharge. In the comparison of utility score by severity in acute stage and discharge, G3 was significantly higher in discharge (0.325 versus 0.580). Utility scores by degree of severity were significantly higher in group G4 than those of G1, G2, and G3 at the acute stage. Utility scores at discharge were significantly higher in groups G3 and G4 than in G1, and there was a significant difference between groups G4 and G2. CONCLUSIONS: At each stage, the utility scores of group G4 were significantly higher than those of groups G1 and G2. Altogether, the utility scores for hospitalized patients with traumatic SCI that were indicated in this study will serve as basic data that can be used while performing spinal regeneration medical procedures in the future.

Traumatic spinal cord injury (TSCI) causes an insult to the central nervous system, often resulting in devastating temporary or permanent neurological impairment and disability, which places a substantial financial burden on the health-care system. This study aimed to clarify the up-to-date epidemiology and demographics of patients with TSCI treated at the largest SCI center in Japan. Data on all patients admitted to the Spinal Injuries Center with TSCI between May 2005 and December 2021 were prospectively collected using a customized, locally designed SCI database named the Japan Single Center Study for Spinal Cord Injury Database (JSSCI-DB). A total of 1152 patients were identified from the database. The study period was divided into the four- or five-year periods of 2005-2009, 2010-2013, 2014-2017, and 2018-2021 to facilitate the observation of general trends over time. Our results revealed a statistically significant increasing trend in age at injury. Since 2014, the average age of injury has increased to exceed 60 years. The most frequent spinal level affected by the injury was high cervical (C1-C4: 45.8%), followed by low cervical (C5-C8: 26.4%). Incomplete tetraplegia was the most common cause or etiology category of TSCI, accounting for 48.4% of cases. As the number of injuries among the elderly has increased, the injury mechanisms have shifted from high-fall trauma and traffic accidents to falls on level surfaces and downstairs. Incomplete tetraplegia in the elderly due to upper cervical TSCI has also increased over time. The percentage of injured patients with an etiology linked to alcohol use ranged from 13.2% (2005-2008) to 19% (2014-2017). Given that Japan has one of the highest aging populations in the world, epidemiological studies in this country will be very helpful in determining health insurance and medical costs and deciding strategies for the prevention and treatment of TSCI in future aging populations worldwide.

Spasticity-defined as involuntary movements caused by insult to upper motor neurons after spinal cord injury (SCI)-interferes with patients' activities of daily living. Spasticity is generally identified and managed in the chronic phase of SCI, but few reports have examined the onset of spasticity after injury. The purpose of this study is to elucidate serial changes in spasticity after SCI and clarify the timing of severe spasticity. We prospectively examined individuals with acute traumatic SCI admitted within two weeks after injury. Severity of spasticity was evaluated using the Modified Ashworth Scale (MAS) at 2, 4, 6, and 8 weeks, followed by 3, 4, 5, and 6 months after injury. After completing evaluation of the cohort, the patients were divided into two groups: a spasticity group with MAS scores ≥3 (marked increase in muscle tone through most of the range of motion (ROM)) in at least one joint movement within 6 months of injury and a control group with MAS scores ≤2 in all joint movements throughout the 6 months after injury. Neurological findings such as the American Spinal Injury Association (ASIA) Impairment Scale grades and ASIA motor scores were also assessed at all time points, and the correlations between the onset of spasticity, severity of spasticity, and neurological findings were analyzed. There were 175 patients with traumatic SCI who were assessed consecutively for 6 months after injury. The MAS scores of the group significantly increased over time until 4 months after injury. The spasticity group had significantly higher MAS scores compared with the control group as early as 2 weeks post-injury. We found that the patients with earlier onset of spasticity had higher final MAS scores. No correlation was found between the ASIA Impairment Scale grade and the onset of spasticity. Our results reveal that the development of severe spasticity may be predictable from as early as 2 weeks after SCI, suggesting that early therapeutic intervention to mitigate problematic spasticity may enhance the benefits of post-injury rehabilitation.
RESUMEN
RATIONALE: Traumatic cervical spinal cord injury (SCI) is a devastating condition leading to respiratory failure that requires permanent mechanical ventilation, which is the main driver of increased medical costs. There is a great demand for establishing therapeutic interventions to treat respiratory dysfunction following severe cervical SCI. PATIENT CONCERNS AND DIAGNOSIS: We present a 24-year-old man who sustained a cervical displaced C2-C3 fracture with SCI due to a traffic accident. As the patient presented with tetraplegia and difficulty in spontaneous breathing following injury, he was immediately intubated and placed on a ventilator with cervical external fixation by halo orthosis. The patient then underwent open reduction and posterior fusion of the cervical spine 3 weeks after injury. Although the patient showed significant motor recovery of the upper and lower limbs over time, only a slight improvement in lung capacity was observed. INTERVENTIONS AND OUTCOMES: At 1.5 years after injury, a diaphragmatic pacing stimulator was surgically implanted to support the patient's respiratory function. The mechanical ventilator support was successfully withdrawn from the patient 14 weeks after implantation. We observed that both the vital capacity and tidal volume of the patient were significantly promoted following implantation. The patient finally returned to daily life without any mechanical support. LESSONS: The findings of this report suggest that diaphragmatic pacing implantation could be a promising treatment for improving respiratory function after severe cervical SCI. To our knowledge, this is the first SCI patient treated with a diaphragm pacing implantation covered by official medical insurance in Japan.

OBJECTIVES: We evaluated the time course of the American Spinal Cord Injury Association (ASIA) impairment scale (AIS) for up to three months in participants within 72â h after traumatic spinal cord injury (TSCI) with complete paralysis. We aimed to determine the most useful sacral-sparing examination (deep anal pressure [DAP], voluntary anal contraction [VAC], S4-5 light touch [LT], or pin prick [PP] sensation) in determining AIS grades. DESIGN: Retrospective cohort study. SETTING: Spinal Injuries Center, Fukuoka, Japan. PARTICIPANTS: Among 668 TSCI participants registered in the Japan Single Center study for Spinal Cord Injury Database (JSSCI-DB) between January 2012 and May 2020, we extracted the data of 80 patients with AIS grade A within 72â h after injury and neurological level of injury (NLI) at T12 or higher. INTERVENTIONS: None. OUTCOME MEASURES: The sacral-sparing examination at the time of the change to incomplete paralysis was compared to the AIS determination using a standard algorithm and with each assessment including the VAC, DAP, S4-5LT, and S4-5PP examinations at the time of AIS functional change. Agreement among assessments was evaluated using weighted kappa coefficients. The relationship was evaluated using Spearman's rank correlation coefficients. RESULTS: Fifteen participants (18.8%) improved to incomplete paralysis (AIS B to D) within three months after injury. The single assessment among the sacral-sparing examinations with the highest agreement and strongest correlation with AIS determination was the S4-5LT examination (k = 0.89, P < 0.01, r = 0.84, P < 0.01). CONCLUSIONS: The S4-5LT examination is key in determining complete or incomplete paralysis due to its high discriminatory power.
