Educational needs and preferences of adult patients with acute pain: a mixed-methods systematic review.

ABSTRACT: Many patients experience acute pain, which has been associated with numerous negative consequences. Pain education has been proposed as a strategy to improve acute pain management. However, studies report limited effects with educational interventions for acute pain in adults, which can be explained by the underuse of the person-centered approach. Thus, we aimed to systematically review and synthetize current evidence from quantitative, qualitative and mixed-methods studies describing patients' needs and preferences for acute pain education in adults. We searched original studies and gray literature in 7 databases, from January 1990 to October 2023. Methodological quality was assessed with the Mixed Methods Appraisal Tool. A total of 32 studies were included (n = 1847 patients), two-thirds of which were qualitative studies of high methodological quality. Most of the studies were conducted over the last 15 years in patients with postsurgical and posttraumatic pain, identified as White, with a low level of education. Patients expressed the greatest need for education when it came to what to expect in pain intensity and duration, as well how to take the medication and its associated adverse effects. The most frequently reported educational preferences were for in-person education while involving caregivers and to obtain information first from physicians, then by other professionals. This review has highlighted the needs and preferences to be considered in pain education interventions, which should be embedded in an approach cultivating communication and partnership with patients and their caregivers. The results still need to be confirmed with different patient populations.

Is the level of consent to a national research registry associated with patient outcomes following traumatic spinal cord injury? A population-based study from the Rick Hansen Spinal Cord Injury Registry (RHSCIR).

OBJECTIVE: We examined the impact of consenting to the Rick Hansen Spinal Cord Injury Registry (RHSCIR) on outcomes: acute length of stay (LOS), in-hospital mortality, medical complications (pressure injuries and pneumonia), and the final discharge destination following a spinal cord injury (SCI) using the national RHSCIR dataset. DESIGN: A retrospective cohort study was conducted using RHSCIR participant data from 2014 to 2019. Participants approached for enrollment were grouped into 1) PC: provided full consent including community follow-up (CFU) interviews, 2) DWC: declined CFU interviews but accepted minimal data collection that may include initial/final interviews and/or those who later withdrew consent, and 3) DC: declined consent to any participation. As no data was collected for the DC group, descriptive, bivariate, and multivariable regression analysis was limited to the PC and DWC groups. RESULTS: Of 2811 participants, 2101 (74.7%) were PC, 553 (19.7%) were DWC, and 157 (5.6%) were DC. DWC participants had significantly longer acute LOS, more acute pneumonias/pressure injuries, and were less likely to be discharged home than PC participants. All these associations - except pneumonia - remained significant in the multivariable analyses. CONCLUSION: Not participating fully in RHSCIR was associated with more complications and longer hospital stays.

Classifying clinical phenotypes of functional recovery for acute traumatic spinal cord injury. An observational cohort study.

PURPOSE: Identify patient subgroups with different functional outcomes after SCI and study the association between functional status and initial ISNCSCI components. METHODS: Using CART, we performed an observational cohort study on data from 675 patients enrolled in the Rick-Hansen Registry(RHSCIR) between 2014 and 2019. The outcome was the Spinal Cord Independence Measure (SCIM) and predictors included AIS, NLI, UEMS, LEMS, pinprick(PPSS), and light touch(LTSS) scores. A temporal validation was performed on data from 62 patients treated between 2020 and 2021 in one of the RHSCIR participating centers. RESULTS: The final CART resulted in four subgroups with increasing totSCIM according to PPSS, LEMS, and UEMS: 1)PPSS < 27(totSCIM = 28.4 ± 16.3); 2)PPSS ≥ 27, LEMS < 1.5, UEMS < 45(totSCIM = 39.5 ± 19.0); 3)PPSS ≥ 27, LEMS < 1.5, UEMS ≥ 45(totSCIM = 57.4 ± 13.8); 4)PPSS ≥ 27, LEMS ≥ 1.5(totSCIM = 66.3 ± 21.7). The validation model performed similarly to the original model. The adjusted R-squared and F-test were respectively 0.556 and 62.2(P-value <0.001) in the development cohort and, 0.520 and 31.9(P-value <0.001) in the validation cohort. CONCLUSION: Acknowledging the presence of four characteristic subgroups of patients with distinct phenotypes of functional recovery based on PPSS, LEMS, and UEMS could be used by clinicians early after tSCI to plan rehabilitation and establish realistic goals. An improved sensory function could be key for potentiating motor gains, as a PPSS ≥ 27 was a predictor of a good function.

After a traumatic Spinal Cord Injury (SCI), early neurological examination using the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is recommended to determine initial injury severity and prognosis.This study identified three initial ISNCSCI components defining four subgroups of SCI patients with different expectations in functional outcomes, namely the initial pinprick sensory score, the Lower Extremity Motor Score, and the Upper Extremity Motor Score.Clinicians could use these subgroups early after tSCI to plan rehabilitation and set realistic therapeutic goals regarding functional outcomes.In clinical practice, careful and accurate assessment of pinprick sensation early after the SCI is crucial when predicting function or stratifying patients based on the expected function.

Does Improvement in American Spinal Injury Association Impairment Scale Grade Correlate With Functional Recovery in All Patients With a Traumatic Spinal Cord Injury?

OBJECTIVE: The aim of the study is to determine what improvement on the American Spinal Injury Impairment Scale correlates with functional status after a traumatic spinal cord injury. DESIGN: We performed an observational cohort study, analyzing prospective data from 168 patients with traumatic spinal cord injury admitted to a single level 1 trauma center. A multivariable analysis was performed to assess the relationship between functional status (from the Spinal Cord Independence Measure) at 1-year follow-up and American Spinal Injury Impairment Scale grade (baseline and 1-yr follow-up), while taking into account covariables describing the sociodemographic status, trauma severity, and level of neurological injury. RESULTS: Individuals improving to at least American Spinal Injury Impairment Scale grade D had significantly higher Spinal Cord Independence Measure score compared with those not reaching American Spinal Injury Impairment Scale D (89.3 ± 15.2 vs. 52.1 ± 20.4) and were more likely to reach functional independence (68.5% vs. 3.6%), regardless of the baseline American Spinal Injury Impairment Scale grade. Higher final Spinal Cord Independence Measure was more likely with an initial American Spinal Injury Impairment Scale grade D (ß = 1.504; 95% confidence interval = 0.46-2.55), and a final American Spinal Injury Impairment Scale grade D (ß = 3.716; 95% CI = 2.77-4.66) or E (ß = 4.422; 95% CI = 2.91-5.93). CONCLUSIONS: Our results suggest that reaching American Spinal Injury Impairment Scale grade D or better 1 yr after traumatic spinal cord injury is highly predictive of significant functional recovery, more so than the actual improvement in American Spinal Injury Impairment Scale grade from the injury to the 1-yr follow-up.

Validation of a New Tool to Detect and Characterize Spinal Cord Injury in the Acute Trauma Patient: The Montreal Acute Classification of Spinal Cord Injury.

STUDY DESIGN: Retrospective validation protocol. OBJECTIVE: The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most comprehensive tool for classifying spinal cord injuries (SCI), but it is not adapted for the evaluation of trauma patients. The objective is to develop and validate a streamlined tool, the Montreal Acute Classification of Spinal Cord Injury (MAC-SCI) that can be integrated in the evaluation of trauma patients to detect and characterize traumatic SCI (tSCI). METHODS: The completion rate of the ISCNSCI during initial evaluation after tSCI was estimated at a Level-1 trauma center specialized in SCI care. Using a modified Delphi technique, we designed the MAC-SCI, a new tool to detect and characterize the severity grade and level of SCI in the polytrauma patient. A cohort consisting of 35 consecutive tSCI patients with complete ISNCSCI documentation was used to validate the MAC-SCI. The severity grade and neurological level of injury (NLI) were assessed using the MAC-SCI, and compared to those obtained with the ISNCSCI. RESULTS: Only 33% of 148 patients admitted after a tSCI had a complete ISNCSCI performed at initial presentation. The MAC-SCI retains 53 of the 134 elements from the ISNCSCI. There was a 100% concordance in severity grade between the MAC-SCI and ISNCSCI. The NLI were within 2 levels between the MAC-SCI and ISNCSI for 100% of patients. CONCLUSION: The MAC-SCI is a streamlined tool that accurately detects and characterizes tSCI in the acute trauma setting. It could be implemented in trauma protocols to guide the management of SCI patients. LEVEL OF EVIDENCE: Level III Diagnostic criteria.

Is it safe to initiate activity-based therapy within days following traumatic spinal cord injury? Preliminary results from the PROMPT-SCI trial.

CONTEXT: Activity-based therapy initiated within days of the accident could prevent complications and improve neurofunctional outcomes in patients with traumatic spinal cord injury (TSCI). However, it has never been attempted in humans with TSCI because of practical obstacles and potential safety concerns. The PROMPT-SCI trial is the first attempt at implementing ABT within the first days following a TSCI (i.e. very early ABT; VE-ABT). The objective is to determine if VE-ABT can be initiated safely in the intensive care unit (ICU) within 48 h of early decompressive surgery. DESIGN: As part of the PROMPT-SCI trial, 15 adult patients with severe TSCI were enrolled between April and November of 2021. The intervention consisted of 30-minute sessions of motor-assisted in-bed leg cycling starting within 48 h of early spinal surgery. Safety was assessed through continuous monitoring of vital signs and recording of adverse events during and after sessions. The main outcome measure was the achievement (yes or no) of a full and safe session within 48 h of early surgery. FINDINGS: Out of the 15 participants, 10 (66.6%) achieved this outcome. Out of the remaining 5, 2 were not cleared to engage in cycling within 48 h of surgery and 3 initiated cycling within 48 h but stopped prematurely. All 5 eventually completed a full and safe session within the next 1-2 days. In all 15 participants, there were no neurological deteriorations after the first completed session. CONCLUSION: Our results suggest that it is safe and feasible to perform a first session of VE-ABT within days of a severe TSCI with no serious adverse events and excellent completion rates.

How do early perioperative changes in AIS grade correlate with long-term neurological recovery? A retrospective cohort study.

CONTEXT/OBJECTIVE: Providing accurate counseling on neurological recovery is crucial after traumatic spinal cord injury (TSCI). The early neurological changes that occur in the subacute phase of the injury (i.e. within 14 days of early decompressive surgery) have never been documented. The objective of this study was to assess peri-operative neurological improvements after acute TSCI and determine their relationship with long-term neurological outcomes, measured 6-12 months following the injury. METHODS: A retrospective cohort study of 142 adult TSCI patients was conducted. Early peri-operative improvement was defined as improvement of at least 1 AIS grade between the pre-operative and follow-up (6-12 months post-TSCI) assessment. neurological improvement of at least 1 AIS grade. RESULTS: Out of the 142 patients, 18 achieved a peri-operative improvement of at least 1 AIS grade. Presenting a pre-operative AIS grade B and having shorter surgical delays were the main factors associated with stronger odds of achieving this outcome. Out of the 140 patients who still had potential for improvement at the time of the post-operative assessment, 44 achieved late neurological recovery (improvement of at least 1 AIS grade between the post-operative assessment and follow-up). Patients who presented a perioperative improvement seemed more likely to achieve later neurological improvement as well, although this was not statistically significant. CONCLUSION: Our results suggest that it is important to assess early perioperative neurological changes within 14 days of surgery because it can provide beneficial insight on long-term neurological outcomes for some patients. In addition, earlier surgery may promote early neurological recovery.

Educational needs and preferences of adult patients with acute or chronic pain: a mixed methods systematic review protocol.

OBJECTIVES: This review will aim to synthesize the available quantitative and qualitative evidence on the educational needs and preferences of adult patients with acute or chronic pain. INTRODUCTION: Acute and chronic pain are prevalent problems and are associated with significant individual and societal consequences. Education is a critical component of pain management. However, the impact of educational interventions on pain outcomes remains limited. The lack of patient input--what patients want to know and how they want to be informed--is one of the main issues underlying intervention design. INCLUSION CRITERIA: We will include qualitative, quantitative, and mixed methods studies describing the educational needs and preferences of adult patients with acute or chronic pain. METHODS: This review will follow the JBI guidelines for mixed methods systematic reviews. We will search MEDLINE (PubMed), Embase (Ovid), PsycINFO (Ovid), CINAHL (EBSCO), the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and ProQuest Dissertations and Theses. The search strategy will commence from the year 1990 onward and there will be no language restrictions. The retrieved titles, abstracts, and full-text reports will be screened by pairs of independent reviewers. These pairs of reviewers will also independently extract data using the JBI tools for mixed methods systematic reviews. Methodological quality will be assessed using the mixed methods appraisal tool. A convergent integrated approach to synthesis and integration of the quantitative and qualitative data will be used. REVIEW REGISTRATION: PROSPERO CRD42022303834.

Do all patients with functional motor-incomplete (AIS-D) traumatic spinal cord injury need specialized inpatient functional rehabilitation? A prospective observational cohort study proposing clinical criteria for home-based rehabilitation after acute care.

CONTEXT/OBJECTIVE: Functional motor-incomplete AIS-D traumatic spinal cord injury (tSCI) represents an important growing population in neuro-traumatology. There is thus an important need for establishing strategies to optimize SCI rehabilitation resources. This study aims at proposing eligibility criteria to select individuals who could be discharged home (home-based rehabilitation) after acute care following an AIS-D tSCI and investigate its impact on the long-term functional status and quality of life (QOL), as compared to transfer to inpatient functional rehabilitation (IFR) resources. DESIGN: An observational prospective cohort study. SETTING: A single Level-1 specialized trauma center. PARTICIPANTS: 213 individuals sustaining an AIS-D tSCI. INTERVENTIONS: Home-based rehabilitation based on clinical specific criteria to be assessed by the acute care team. OUTCOME MEASURES: Functional status and QOL as assessed by the Spinal Cord Independence Measure version 3 and WHOQOL-BREF questionnaire one year following the injury, respectively. RESULTS: A total 37.9% of individuals fulfilled proposed criteria for home-based rehabilitation after acute care. As expected, this group was significantly younger, experienced lesser comorbidities and acute complications, and showed higher motor and sensory function compared to the IFR group. Home-rehabilitation was associated with a higher long-term functional status, physical and psychological QOL, when accounting for relevant confounding factors after an acute AIS-D tSCI. There was no readmission due to failure of home-based rehabilitation. CONCLUSION: Home-based rehabilitation in selected individuals sustaining an acute AIS-D tSCI is a safe and interesting strategy to optimize the long-term outcome in terms of functional recovery, physical and psychological QOL, as well as to optimize inpatient rehabilitation resources. The proposed eligibility criteria can be used by the acute care team to select the optimal discharge orientation in this important subpopulation.

Optoelectronic Pressure Sensor Based on the Bending Loss of Plastic Optical Fibers Embedded in Stretchable Polydimethylsiloxane.

We report the design and testing of a sensor pad based on optical and flexible materials for the development of pressure monitoring devices. This project aims to create a flexible and low-cost pressure sensor based on a two-dimensional grid of plastic optical fibers embedded in a pad of flexible and stretchable polydimethylsiloxane (PDMS). The opposite ends of each fiber are connected to an LED and a photodiode, respectively, to excite and measure light intensity changes due to the local bending of the pressure points on the PDMS pad. Tests were performed in order to study the sensitivity and repeatability of the designed flexible pressure sensor.

Are early-onset spasms predictive of poor neurological recovery after traumatic spinal cord injury?

CONTEXT: Following spinal cord injury (SCI), early spasms are associated with decreased functional recovery. It has also been hypothesized that early spasticity might sign underlying maladaptive neuroplasticity, which could translate in worse neurological outcomes. OBJECTIVE: In this context, this paper aims to evaluate if early-onset spasms are also associated with neurological outcomes after SCI. METHODS: A retrospective review of 196 cases from a prospective SCI database was conducted. The presence of early spasms during the acute hospitalization was assessed by a single physiatrist. The characteristics and long-term neurological outcomes of individuals with and without early spasms were first compared. Multivariate regression analyses were then performed to determine the relationship between early spasms and neurological outcomes. RESULTS: 30.1% (N = 59) of patients presented early spasms. These patients had several distinguishing characteristics including higher odds of tetraplegia (vs. paraplegia) and more severe injuries. At the bivariate level, patients with early spasms had higher odds of improving at least 1 AIS grade between baseline and follow-up. However, this was not significant at the multivariate level. CONCLUSIONS: Early spasms are not significantly associated with poorer neurological outcomes, contrasting with the unwritten consensus that early spasticity translates maladaptive neuroplasticity.

Does Older Age Affect the Likelihood to Achieve Normal Quality of Life After Traumatic Spinal Cord Injury? A Prospective Observational Cohort Study.

Previous studies suggest that health-related quality of life (HRQoL) is impaired after a traumatic spinal cord injury (TSCI) and may be worse with older age. This study determines whether the expectations to achieve normal HRQoL in Canadians after a TSCI is indeed influenced by older age. A prospective observational study was conducted on adult patients admitted acutely at a single level-1 trauma center after a TSCI. We assessed HRQoL using the SF-36 physical and mental component summary (PCS and MCS) scores obtained one year post injury. Using Canadian normative HRQoL data matched for age and sex, we defined normal PCS and MCS as a score within 2 standard deviations with respect to the normative Canadian mean. We then conducted logistic regression models to determine the relationship between age at the time of injury and the likelihood of achieving normal PCS and MCS, while controlling for confounding variables. Overall, 39.3% of individuals displayed normal PCS, whereas 80.4% displayed normal MCS. When adjusted for confounders, older age remained significantly associated with increased likelihood of achieving normal PCS (Odds Ratio: 1.03; 95% Confidence Interval: 1.01-1.06; P = 0.002). We observed no association between age and achieving normal MCS. A significant proportion of individuals can achieve a normal HRQoL similar to their healthy peers following a TSCI, particularly for the mental component. When compared to younger individuals, older individuals are more likely to achieve normal PCS and present a similar likelihood for achieving normal MCS.

Strategies to prevent long-term opioid use following trauma: a Canadian practice survey.

PURPOSE: To evaluate how Canadian clinicians involved in trauma patient care and prescribing opioids perceive the use and effectiveness of strategies to prevent long-term opioid therapy following trauma. Barriers and facilitators to the implementation of these strategies were also assessed. METHODS: We conducted a web-based cross-sectional survey. Potential participants were identified by trauma program managers and directors of the targeted departments in three Canadian provinces. We designed our questionnaire using standard health survey research methods. The questionnaire was administered between April 2021 and November 2021. RESULTS: Our response rate was 47% (350/744), and 52% (181/350) of participants completed the entire survey. Most respondents (71%, 129/181) worked in teaching hospitals. Multimodal analgesia (93%, 240/257), nonsteroidal anti-inflammatory agents (77%, 198/257), and physical stimulation (75%, 193/257) were the strategies perceived to be the most frequently used. Several preventive strategies were perceived to be very effective by over 80% of respondents. Of these, some that were reported as not being frequently used were perceived to be among the most effective ones, including guidelines or protocols, assessing risk factors for opioid misuse, physical health follow-up by a professional, training for clinicians, patient education, and prescription monitoring systems. Staff shortages, time constraints, and organizational practices were identified as the main barriers to the implementation of the highest ranked preventive strategies. CONCLUSIONS: Several strategies to prevent long-term opioid therapy following trauma are perceived as being effective by those prescribing opioids in this population. Some of these strategies appear to be commonly used in everyday practice and others less so. Future research should focus on which preventive strategies should be given higher priority for implementation before assessing their effectiveness.

RéSUMé: OBJECTIF: Évaluer comment les cliniciens canadiens impliqués dans les soins aux patients traumatisés et prescrivant des opioïdes perçoivent l'utilisation et l'efficacité des stratégies visant à prévenir le traitement prolongé par opioïde après un traumatisme. Les obstacles et facilitateurs de la mise en œuvre de ces stratégies ont aussi été analysés. MéTHODES: Nous avons réalisé une enquête transversale via le Web. Les participants potentiels ont été identifiés par les gestionnaires et directeurs de programmes de traumatologie des départements ciblés dans trois provinces canadiennes. Nous avons conçu notre questionnaire en utilisant la méthodologie de recherche usuelle des enquêtes de santé. Le questionnaire a été administré entre avril 2021 et novembre 2021. RéSULTATS: Notre taux de réponse a été de 47 % (350/744) et 52 % (181/350) des participants ont complété l'enquête dans sa totalité. La majorité des personnes interrogées (71 %, 129/181) travaillait dans des hôpitaux universitaires. L'analgésie multimodale (93 %, 240/257), les anti-inflammatoires non stéroïdiens (77 %, 198/257) et la stimulation physique (75 %, 193/257) étaient les stratégies perçues comme étant le plus fréquemment utilisées. Plusieurs stratégies préventives étaient perçues comme étant très efficaces par plus de 80 % des répondants. Parmi celles-ci, certaines étaient signalées comme n'étant pas utilisées très souvent, mais perçues comme étant les plus efficaces, notamment les lignes directrices et protocoles évaluant les facteurs de risque d'utilisation abusive des opioïdes, le suivi de la santé physique par un professionnel, la formation des cliniciens, l'éducation des patients et les systèmes de suivi des prescriptions. La pénurie de personnels, les contraintes de temps et les pratiques de l'établissement ont été identifiées comme étant les principaux obstacles à la mise en place des stratégies préventives classées parmi les premières. CONCLUSIONS: Plusieurs stratégies de prévention du traitement par opioïdes à long terme après un traumatisme sont perçues comme efficaces par ceux qui les prescrivent à cette population de patients. Certaines de ces stratégies apparaissent comme couramment utilisées dans la pratique quotidienne et d'autres moins souvent. La recherche future devrait se concentrer sur la détermination des stratégies préventives auxquelles il faudrait accorder la plus grande priorité de mise en œuvre avant d'évaluer leur efficacité.

Does Wait Time During Acute Care for Transfer to Rehabilitation Admission Impact the Outcomes After a Traumatic Spinal Cord Injury?: A Retrospective Cohort Study.

BACKGROUND: The objective of this study was to determine the impact of wait time in acute care for inpatient functional rehabilitation admission on the inpatient functional rehabilitation length of stay and functional outcome after a traumatic spinal cord injury. METHODS: A retrospective cohort including 277 patients admitted to a single level 1 spinal cord injury acute care center was completed. Partial correlations were used between wait time (in days) for transfer to inpatient functional rehabilitation, the inpatient functional rehabilitation length of stay, and the Spinal Cord Independence Measure total score in the chronic period, adjusting for confounding variables. Stratified analyses were carried out based on the age group and severity of the injury. RESULTS: Patients had to wait a mean of 7.3 ± 6.4 days (median = 6 days, interquartile range = 2-10 days, max = 29 days) for inpatient functional rehabilitation admission after rehabilitation readiness, which was not associated with the outcomes when adjusted ( P > 0.05). However, individuals 65 yrs or older with a motor-complete injury showed a lower functional status when exposed to wait time for transfer ( r = -0.87, P = 0.02). CONCLUSIONS: Wait time up to 29 days may have no impact on the inpatient functional rehabilitation length of stay nor functional outcome after traumatic spinal cord injury. However, additional resources and/or prioritization should be considered for vulnerable subgroups.

Who Recovers Independent Bowel Management During the First Year After a Traumatic Spinal Cord Injury?: A Case-Control Study.

OBJECTIVES: The aims of the study were (1) to document the characteristics of patients with impaired bowel functioning during the subacute and chronic phases and (2) to identify factors associated with recovery of independent bowel functioning during the first year after traumatic spinal cord injury in patients who present impaired bowel functioning during the subacute phase, when bowel rehabilitation is completed. DESIGN: This is a case-control study on 123 adult traumatic spinal cord injury patients. Bowel function assessments using item 7 of the Spinal Cord Independence Measure III were obtained 3 mos after traumatic spinal cord injury and during the early chronic phase. Univariate and multivariate analyses were conducted to identify predictors associated with recovery of independent bowel functioning between the initial assessment and follow-up. RESULTS: Of the 110 patients available for analysis, 54 (49%) displayed impaired bowel functioning 3 mos after traumatic spinal cord injury. Of these, 19 (35%) recovered independent bowel functioning over the following 9 mos. The total motor score was the only significant predictor of this outcome. A total motor score lower than 42 was 100% predictive of absence of recovery. CONCLUSIONS: Recovering independent bowel management 1 yr after traumatic spinal cord injury was possible in 35% of patients despite impaired bowel functioning during the subacute phase. The total motor score measured 3 mos after injury could be useful for prognosticating potential for bowel functioning recovery because patients with total motor score lower than 42 are unlikely to recover.

Protocol for rapid onset of mobilisation in patients with traumatic spinal cord injury (PROMPT-SCI) study: a single-arm proof-of-concept trial of early in-bed leg cycling following acute traumatic spinal cord injury.

INTRODUCTION: Activity-based therapy (ABT) is an important aspect of rehabilitation following traumatic spinal cord injury (SCI). Unfortunately, it has never been adapted to acute care despite compelling preclinical evidence showing that it is safe and effective for promoting neurological recovery when started within days after SCI. This article provides the protocol for a study that will determine the feasibility and explore potential benefits of early ABT in the form of in-bed leg cycling initiated within 48 hours after the end of spinal surgery for SCI. METHODS AND ANALYSIS: PROMPT-SCI (protocol for rapid onset of mobilisation in patients with traumatic SCI) is a single-site single-arm proof-of-concept trial. Forty-five patients aged 18 years or older with a severe traumatic SCI (American Spinal Injury Association Impairment Scale grade A, B or C) from C0 to L2 undergoing spinal surgery within 48 hours of the injury will be included. Participants will receive daily 30 min continuous sessions of in-bed leg cycling for 14 consecutive days, initiated within 48 hours of the end of spinal surgery. The feasibility outcomes are: (1) absence of serious adverse events associated with cycling, (2) completion of 1 full session within 48 hours of spinal surgery for 90% of participants and (3) completion of 11 sessions for 80% of participants. Patient outcomes 6 weeks and 6 months after the injury will be measured using neurofunctional assessments, quality of life questionnaires and inpatient length of stay. Feasibility and patient outcomes will be analysed with descriptive statistics. Patient outcomes will also be compared with a matched historical cohort that has not undergone in-bed cycling using McNemar and Student's t-tests for binary and continuous outcomes, respectively. ETHICS AND DISSEMINATION: PROMPT-SCI is approved by the Research Ethics Board of the CIUSSS NIM. Recruitment began in April 2021. Dissemination strategies include publications in scientific journals and presentations at conferences. TRIAL REGISTRATION NUMBER: NCT04699474.

Early Clinical Prediction of Independent Outdoor Functional Walking Capacity in a Prospective Cohort of Traumatic Spinal Cord Injury Patients.

OBJECTIVE: The first objective was to identify a method for early prediction of independent outdoor functional walking 1 yr after a traumatic spinal cord injury using the motor and sensory function derived from the International Standards for Neurological Classification of Spinal Cord Injury assessment during acute care. Then, the second objective was to develop a clinically relevant prediction rule that would be accurate, easy to use, and quickly calculated in clinical setting. DESIGN: A prospective cohort of 159 traumatic spinal cord injury patients was analyzed. Bivariate correlations were used to determine the assessment method of motor strength and sensory function as well as the specific dermatomes and myotomes best associated with independent outdoor functional walking 1 yr after injury. An easy-to-use clinical prediction rule was produced using a multivariable linear regression model. RESULTS: The highest motor strength for a given myotome (L3 and L5) and preserved light touch sensation (dermatome S1) were the best predictors of the outcome. The proposed prediction rule displayed a sensitivity of 84.21%, a specificity of 85.54%, and a global accuracy of 84.91% for classification. CONCLUSIONS: After an acute traumatic spinal cord injury, accurately predicting the ability to walk is challenging. The proposed clinical prediction rule aims to enhance previous work by identifying traumatic spinal cord injury patients who will reach a mobility level that fosters social participation and quality of life in the chronic period after the injury.

Are early clinical manifestations of spasticity associated with long-term functional outcome following spinal cord injury? A retrospective study.

STUDY DESIGN: Retrospective study of a prospective cohort of patients with traumatic spinal cord injury (SCI). OBJECTIVES: Determine the relationship between the occurrence of early spasticity, defined as the development of signs and/or symptoms of spasticity during the hospitalization in traumatology, and the functional outcome 6-12 months following a SCI. Secondly, to determine the specific impact of early clonus, velocity-dependent hypertonia and/or muscle spasms on the functional outcome at the same timepoint. SETTING: Single trauma center specialized in SCI care. METHODS: One hundred sixty-two patients sustaining an acute traumatic SCI were included in the analyses. Comparative analysis was performed to describe the characteristics of patients with early spasticity. Correlations were performed to determine the relationship between the clinical signs of spasticity and the Spinal Cord Independence Measure (SCIM) scores collected 6-12 months after SCI. RESULTS: 51.9% of the cohort developed clinical signs of spasticity during the hospitalization in traumatology (29.7 days) following SCI. These showed a significantly lower total SCIM score and subscores compared to individuals without early spasticity at follow-up (p < 0.05). After adjusting for confounding factors, the occurrence of early spasms was only clinical sign of spasticity significantly associated with a decreased mobility at follow-up (r = -0.17, p = 0.04). CONCLUSIONS: The development of signs and symptoms of spasticity, in particular the occurrence of spasms in the first month following the injury may be associated with decreased functional outcome and mobility. Early assessment of spasticity following SCI is thus recommended.

Early Predictors of Neurological Outcomes After Traumatic Spinal Cord Injury: A Systematic Review and Proposal of a Conceptual Framework.

BACKGROUND: Neurological outcomes after traumatic spinal cord injury are variable and depend on patient-, trauma-, and treatment-related factors as well as on spinal cord injury characteristics, imaging, and biomarkers. OBJECTIVE: The aims of the study were to identify and classify the early predictors of neurological outcomes after traumatic spinal cord injury. DATA SOURCES: The Medline, PubMed, Embase, and the Cochrane Central Database were searched using medical subject headings. The search was extended to the reference lists of identified studies. STUDY ELIGIBILITY CRITERIA: The study eligibility criteria were assessment of neurological outcomes as primary or secondary outcome, predictors collected during the acute phase after traumatic spinal cord injury, and multivariate design. PARTICIPANTS: The participants were adult patients with traumatic spinal cord injury followed at least 3 mos after injury. STUDY APPRAISAL AND SYNTHESIS METHODS: The quality of studies was assessed by two independent reviewers using the Study Quality Assessment Tools for Observational Cohort and Cross-sectional Studies. The studies' narrative synthesis relied on a classification of the predictors according to quantity, quality, and consistency of the evidence. Results were summarized in a conceptual framework. RESULTS: Forty-nine articles were included. The initial severity of traumatic spinal cord injury (American Spinal Injury Association Impairment Scale, motor score, and neurological level of injury) was the strongest predictor of neurological outcomes: patients with more severe injury at admission presented poor neurological outcomes. Intramedullary magnetic resonance imaging signal abnormalities were also associated with neurological outcomes, as the presence of intramedullary hemorrhage was a factor of poor prognosis. Other largely studied predictors, such as age and surgical timing, showed some inconsistency in results depending on cutoffs. Younger age and early surgery were generally associated with good outcomes. Although widely studied, other factors, such as vertebral and associated injuries, failed to show association with outcomes. Cerebrospinal fluid inflammatory biomarkers, as emerging factors, were significantly associated with outcomes. CONCLUSIONS: This study provides a comprehensive review of predictors of neurological outcomes after traumatic spinal cord injury. It also highlights the heterogeneity of outcomes used by studies to assess neurological recovery. The proposed conceptual framework classifies predictors and illustrates their relationships with outcomes.

Clinical judgment is a cornerstone for validating and using clinical prediction rules: a head-to-head study on ambulation outcomes for spinal cord injured patients.

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: Clinical prediction rules (CPRs) are an effervescent topic in the medical literature. Recovering ambulation after a traumatic spinal cord injury (tSCI) is a priority for patients and multiple CPRs have been proposed for predicting ambulation outcomes. Our objective is to confront clinical judgment to an established CPR developed for patients with tSCI. SETTINGS: Level one trauma center specialized in tSCI and its affiliated rehabilitation center. METHOD: In this retrospective comparative study, six physicians had to predict the ambulation outcome of 68 patients after a tSCI based on information from the acute hospitalization. Ambulation was also predicted according to the CPR of van Middendorp (CPR-vM). The success rate of the CPR-vM and clinicians to predict ambulation was compared using criteria of 5% for defining clinical significance, and a level of statistical significance of 0.05 for bilateral McNemar tests. RESULTS: There was no statistical difference between the overall performance of physicians (success rate of 79%) and of the CPR-vM (81%) for predicting ambulation. The differences between the CPR-vM and physicians varied clinically and significantly with the level of experience, clinical setting, and field of expertise. CONCLUSION: Confronting CPRs with the judgment of a group of clinicians should be an integral part of the design and validation of CPRs. Head-to-head comparison of CPRs with clinicians is also a cornerstone for defining the optimal strategy for translation into the clinical practice, and for defining which clinician and specific clinical context would benefit from using the CPR.
