SCIM III is reliable and valid in a separate analysis for traumatic spinal cord lesions

Comparing surgeries to restore upper extremity function in tetraplegia: Impact on function during the perioperative period

CONTEXT/OBJECTIVE

To assess short-term changes in health outcomes in people with cervical-level spinal cord injury (SCI) who underwent upper extremity (UE) reconstruction via either novel nerve transfer (NT) or traditional tendon transfer (TT) surgery with individuals who did not undergo UE surgical reconstruction.

DESIGN

Prospective, comparative cohort pilot study.

PARTICIPANTS

34 participants with cervical SCI met the following inclusion criteria: age 18 or older, greater than 6 months post-injury, and mid-cervical level SCI American Spinal Injury Association Impairment Scale (AIS) A, B or C.

SETTING

Two tertiary academic hospitals and their affiliated veterans' hospitals.

METHODS

Health outcomes were assessed using two previously validated measures, the Spinal Cord Independence Measure (SCIM) and Short-Form Health Survey (SF-36). Demographic, surgical, and survey data were collected at the initial evaluation and one month postoperatively/post-baseline.

RESULTS

34 participants with cervical SCI were recruited across three cohorts: no surgery (n = 16), NT (n = 10), and TT (n = 8). The TT group had a decline in SCIM and SF-36 scores whereas the NT and no surgery groups experienced little change in independence or health status in the immediate perioperative period.

CONCLUSIONS

Surgeons and rehabilitation providers must recognize differences in the perioperative needs of people with cervical SCI who chose to have restorative UE surgery. Future work should focus on further investigation of health outcomes, change in function, and improving preoperative counseling and cross-disciplinary management.

The beneficial effects of the herbal medicine Di-Huang-Yin-Zi on patients with traumatic cauda equina injury: A randomized, double-blind, placebo-controlled study

OBJECTIVE

This study aimed to investigate the safety and efficacy of Di-Huang-Yin-Zi (DHYZ), also known as Rehmanniae Yin-Zi, a traditional Chinese medicinal formula used for treating of neurological disorders in patients with traumatic cauda equina injury (TCEI).

METHODS

In this double-blind, placebo-controlled study, TCEI patients with American Spinal Injury Association (ASIA) impairment grades C were randomized to receive either DHYZ (n = 30) or placebo (n = 30) for 8 weeks. Both groups also received rehabilitation therapy and oral mecobalamine therapy during the treatment. Motor and sensory functions, as well as walking ability, were assessed biweekly.

RESULTS

At the end of the treatment, the DHYZ group exhibited significantly higher scores in sensory and motor function, as well as walking ability, compared to the placebo group (all P < 0.05). Additionally, no serious side effects were reported.

CONCLUSION

DHYZ has the potential to accelerate nerve repair and may serve as an effective adjuvant therapy to enhance the recovery of nerve function in patients with TCEI.

Construct validity, responsiveness, and interpretability of the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI)

OBJECTIVE

We investigated the construct validity, responsiveness, and interpretability of the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI) to determine its usefulness in measuring the functional level of gait.

PATIENTS AND METHODS

This was a prospective observational study following the checklist of the Consensus-Based Standards for Selecting Health Measurement Instruments. The SCI-FAI consists of three items: Gait Parameter, Assistive Devices, and Temporal. We recruited 55 patients diagnosed with a spinal cord injury (SCI) in the subacute or chronic phase from Ibaraki Prefectural University of Health Sciences Hospital. Construct validity was clarified by hypothesis testing and the rate of hypothesis verification. We divided responsiveness into subacute and chronic groups and determined the correlation between the changes in the two timepoints of the SCI-FAI and 6-minute walk test. Interpretability involved the calculation of cutoff values for indoor and outdoor walking.

RESULTS

Construct validity was confirmed for 12 of the 15 hypotheses, indicating high construct validity. In the subacute group, Gait Parameter and Assistive Devices showed moderate responsiveness. Interpretability showed that the Gait Parameter was perfect in 19 of the 20 subjects who did not need a walking aid when walking. The cutoff value for Gait Parameter for indoor walking was 17.5 points (AUC 0.91) and that for Assistive Devices was 9.5 points (AUC 0.88). The cutoff values for outdoor walking were Gait Parameter 18.5 points (AUC 0.96) and Assistive Devices 10.5 points (AUC 0.94).

CONCLUSION

Our results demonstrated that the SCI-FAI has adequate construct validity, moderate responsiveness in SCI patients in the subacute phase, and interpretability in the gait assessment of individuals with SCIs. Gait Parameter is likely to show a ceiling effect for people with SCIs who can walk without using an upper-limb walking aid.

Upper Extremity Surgery in Cervical Spinal Cord Injury: A Prospective Comparative Mixed-Methods Study

BACKGROUND

Cervical spinal cord injury (SCI) has a devastating effect on health and independence. Restoring upper extremity function is a top priority and can be accomplished by tendon transfer (TT) and nerve transfer (NT) surgery. The purpose of this prospective comparative study was to assess long-term changes in upper extremity function between surgical (TT or NT) and nonsurgical groups through a comprehensive mixed-methods approach.

METHODS

This multicenter cohort study compared data among 3 groups: those undergoing no surgery, TT surgery, or NT surgery. Quantitative data from the Spinal Cord Independence Measure (SCIM) and 36-item Short Form Health Survey were collected at baseline and long-term follow-up (6 to 24 months). Qualitative semistructured interview data were also obtained from these participants and their identified caregivers at baseline, early follow-up (1 month), and long-term follow-up (6 to 24 months).

RESULTS

Thirty-one participants had quantitative data across all time points: no surgery ( n = 14), TT ( n = 7), and NT ( n = 10). SCIM scores improved in TT and NT groups compared with the no-surgery group ( P < 0.05). The 36-Item Short Form Health Survey scores did not differ among groups. Qualitative data analysis ( n = 168 interviews) corroborated SCIM findings: surgical participants and their caregivers reported improvement in transfers and ability to perform activities of daily living, including grooming and self-catheterization. Improved use of electronics and ability to operate a motor vehicle were also reported. Postoperative therapy was identified as a critical component of achieving gains.

CONCLUSIONS

TT and NT surgery lead to quantitative and qualitative functional gains when compared to no surgery. This comparative information should be used to help surgeons discuss treatment options.

Translation and validation of the Chinese self-report version of Spinal Cord Independence Measure (SCIM-SR): Rasch psychometric analysis and online application

Spinal Cord Independence Measure (SCIM) was an important functional outcome measure specifically designed for spinal cord injury (SCI) patients, with the self-reported version of SCIM (SCIM-SR) published in 2013. This study aims to translate the SCIM-SR into Chinese, and to investigate the validity of Chinese SCIM-SR among SCI patients. This Chinese version of SCIM-SR was translated into Chinese in a standardized approach, and then filled out by a sample of patients with SCI (n = 205) within 3 days after admission. Validity of Chinese SCIM-SR was then analyzed using Rasch analysis and principal component analysis. The subscale Selfcare and subscale Mobility showed good fit to the Rasch model, with no significance found in Chi-square test results for item-trait interaction, using Bonferroni adjustment for the significant level (χ2 =18.125, P = 0.111; χ2 =33.629, P = 0.006). Mean fit residual for items and persons of each subscale were within ± 2.5. The model fit of the subscale of Respiration and Sphincter Management was not satisfactory even after deleting one item and merging two items with local dependence. However, Kaiser-Meyer-Olkin test was > 0.50 in total score and all the subscales of Chinese SCIM-SR, and P < 0.05 in the Bartlett's test. There was no differential item functioning for gender, time post injury, age, and etiology in any of the three subscales. An online version of Chinese SCIM-SR was also developed. It is concluded that the SCIM-SR in Chinese is valid for application in individuals with SCI. SCIM-SR is considered as an important tool for self-reporting functional status from SCI individuals' perspective.

Neuroticism Overestimated? Neuroticism Versus Hypertonia, Pain and Rehabilitation Outcomes in Post-Spinal Cord Injury Patients Rehabilitated Conventionally and with Robotic-Assisted Gait Training

BACKGROUND

The aim of the present study was to analyse the association between neuroticism (one of the Big Five personality traits) and the most common secondary sensorimotor complications occurring in patients after spinal cord injury (SCI), i.e., muscle spasticity (hypertonia) and pain, and to investigate the associations between neuroticism and the effects of conventional rehabilitation (dynamic parapodium) and those using robotic-assisted gait training (RAGT) in this group of patients. In addition, the association of neuroticism with self-efficacy, personal beliefs about pain control, and adopted coping strategies among SCI patients was analysed. These data can be used as a reference for designing effective forms of therapy and support dedicated to this group of patients.

METHODS AND PROCEDURES

Quantitative analysis included 110 patients after SCI. The participants were divided by simple randomisation into a rehabilitation group with RAGT and a rehabilitation group with dynamic parapodium therapy (DPT). The following survey instruments were used for data collection: Revised NEO Personality Inventory (NEO-PI-R); Ashworth Scale; the Spinal Cord Independence Measure III (SCIM III); the Walking Index for Spinal Cord Injury II (WISCI-II); the American Spinal Injury Association Impairment Scale (AIS); the Pain Coping Strategies Questionnaire-CSQ; and the Beliefs about Pain Control Questionnaire-BPCQ.

OUTCOMES AND RESULTS

analyses showed a positive association between neuroticism and spastic tension (rho = 0.39; p < 0.001).

CONCLUSIONS AND IMPLICATIONS

the study showed that a high level of neuroticism correlates with a higher level of spasticity, but no such correlation was observed for pain. Additionally, the study did not show a significant correlation between neuroticism and rehabilitation outcome depending on the rehabilitation modality (RAGT vs. DPT). The results underline the importance of carrying out a psychological diagnosis of patients to provide therapeutic support in the rehabilitation process.

Traumatic and Non-traumatic Radiculomedullary Compressions: A Comparative Analysis

Background Radiculomedullary lesions represent a significant public health issue, with their epidemiological, clinical, and therapeutic characteristics varying depending on whether they are of traumatic or non-traumatic origin. The aim of this study was to compare clinical, therapeutic, and postoperative aspects between traumatic radiculomedullary lesions (TRML) and non-traumatic radiculomedullary lesions (NTRML). Methods This was a prospective cohort study conducted from 2020 to 2023 involving patients suffering from radiculomedullary lesions operated at the Department of Neurosurgery, University Teaching Hospital of Kinshasa. In addition to socio-demographic characteristics, the two patient groups - traumatic and non-traumatic - were compared based on clinical, therapeutic, and postoperative aspects using the American Spinal Injury Association (ASIA) and Spinal Cord Independence Measures (SCIM III) scores.  Results We included 153 patients, with 73 traumatic cases (47.7%) and 80 non-traumatic cases (52.3%). TRMLs were predominantly caused by road traffic accidents (34%) and falls (11%), while NTRMLs were mainly due to disc herniations (22.2%) and tuberculosis (13.7%). The mean age for TRMLs was 35.4 ±12.8 years with a sex ratio of 3.5, compared to 50.7±15.9 years and a sex ratio of 1.1 for NTRMLs. TRMLs were more frequently located in the cervical region (32.8%) and the thoracolumbar junction (40%), whereas NTRMLs predominantly affected the thoracic (22.5%) and lumbar (63.7%) regions. Patients with NTRMLs had more incomplete lesions (98.7%) and better SCIM III scores at admission compared to TRMLs (p ˂ 0.001). TRMLs had more complete deficits 42 (57.3%) vs 1 (1.3%). Both groups significantly improved their ASIA and SCIM III scores postoperatively (p ˂ 0.001) but in a similar manner (Diff-in-diff: ASIA, p=0.955; SCIM, p=0.967). TRMLs developed more complications than NTRMLs (p˂0,001). Only five patients (11.6%) with ASIA A progressed to higher grades, and all remained dependent (SCIM III score ˂50). The average hospital stay was 89.2 ±74.2 days for TRMLs and 57.5±52.9 days for NTRMLs (p˂0.001). Conclusion This study revealed that TRMLs frequently affect young male individuals and are often located in the cervical region and thoracolumbar junction. In contrast, NTRMLs affect older individuals without gender preference and are usually found in the thoracic and lumbar regions. TRMLs often lead to complete deficits, pressure sores, urinary infections, and longer hospital stays compared to NTRMLs. Both patient groups showed significant postoperative improvement with no significant difference between them. However, patients with complete deficits showed less improvement in both groups.

Changes in functional independence after inpatient rehabilitation in patients with spinal cord injury: A simultaneous evaluation of prognostic factors

OBJECTIVE

This study aimed to investigate the improvements of functional independence following inpatient rehabilitation and compare those improvements between different levels and severities of Spinal Cord Injury (SCI). Prognostic factors affecting the patient's outcomes were also studied.

SETTINGS

Rofeideh Rehabilitation Hospital.

OUTCOME MEASURES

Spinal Cord Independence Measure version III (SCIM III), and Functional Independence Measure (FIM).

METHOD

In this retrospective cohort study, 180 patients with SCI were enrolled to record their functional independence upon admission and discharge, and the changes were compared between different levels and severities of injury using non-parametric tests. The prognostic factors of outcomes were studied by generalized estimating equation (GEE) analysis.

RESULTS

The independence changes were significant for all the severities (American Spinal Injury Association Impairment Scale (AIS)) and levels of injury except for the patients with AIS A and B at upper cervical levels (P < 0.05). The level of injury, AIS, Length of Stay (LOS), and pressure ulcer had a significant prognostic value on patient's outcomes. Furthermore, there was a significant difference between different levels of injury with the same AIS grade in functional improvement (P < 0.05), while there was a significant difference between AIS groups with the same level of injury only at upper and middle cervical lesions (P < 0.05).

CONCLUSION

Recording the values of functional independence before and after rehabilitation in individuals with SCI can help clinicians approximately expect the outcomes of future patients. Moreover, a deeper study of the prognostic factors can provide a more logical expectation of rehabilitation outcomes.

Participation and autonomy, independence in activities of daily living and upper extremity functioning in individuals with spinal cord injury

Improvements in care and rehabilitation have resulted in a higher proportion of people living with spinal cord injury (SCI), which calls for an increased focus on participation and autonomy. This observational cross-sectional study investigated the impact of SCI on autonomy and how it correlates to activity performance and upper extremity functioning. A total of 25 adults (mean age 58 years) with chronic cervical or thoracic SCI were included. Self-perceived autonomy was measured with Impact on Participation and Autonomy questionnaire, independence in activities of daily living (ADL) with Spinal Cord Independence Measure, upper extremity functioning with Action Research Arm Test (ARAT) and kinematic measures of the drinking task. The results showed that most participants perceived injury-related restrictions in outdoor autonomy (80%), family role (76%), and in indoor autonomy (72%). Independence in self-care (r = 0.72), mobility (r = 0.59) and upper extremity kinematics of movement time (r = 0.63) and smoothness (r = 0.49) were correlated to indoors autonomy. Social life autonomy was correlated to self-care (r = 0.50) and ARAT (r = 0.41). In conclusion, autonomy was perceived restricted after SCI in several major life areas and correlated with independence in ADL and upper extremity functioning. The aspects of autonomy should be considered more in goal setting and clinical decision-making.

Brain Plasticity in Patients with Spinal Cord Injuries: A Systematic Review

A spinal cord injury (SCI) causes changes in brain structure and brain function due to the direct effects of nerve damage, secondary mechanisms, and long-term effects of the injury, such as paralysis and neuropathic pain (NP). Recovery takes place over weeks to months, which is a time frame well beyond the duration of spinal shock and is the phase in which the spinal cord remains unstimulated below the level of injury and is associated with adaptations occurring throughout the nervous system, often referred to as neuronal plasticity. Such changes occur at different anatomical sites and also at different physiological and molecular biological levels. This review aims to investigate brain plasticity in patients with SCIs and its influence on the rehabilitation process. Studies were identified from an online search of the PubMed, Web of Science, and Scopus databases. Studies published between 2013 and 2023 were selected. This review has been registered on OSF under (n) 9QP45. We found that neuroplasticity can affect the sensory-motor network, and different protocols or rehabilitation interventions can activate this process in different ways. Exercise rehabilitation training in humans with SCIs can elicit white matter plasticity in the form of increased myelin water content. This review has demonstrated that SCI patients may experience plastic changes either spontaneously or as a result of specific neurorehabilitation training, which may lead to positive outcomes in functional recovery. Clinical and experimental evidence convincingly displays that plasticity occurs in the adult CNS through a variety of events following traumatic or non-traumatic SCI. Furthermore, efficacy-based, pharmacological, and genetic approaches, alone or in combination, are increasingly effective in promoting plasticity.

Understanding the experiences, needs, and strengths of people with incomplete spinal cord injury who can ambulate

PURPOSE

To identify the experiences, needs, and strengths of people with incomplete spinal cord injury who can ambulate and to explore and discuss potential supports, services, and programs that would best assist them in the community.

MATERIAL AND METHODS

In this qualitative descriptive study, interviews were the primary means of data collection. These were supplemented with descriptive standardized measures of function and life satisfaction. Qualitative data were analyzed thematically.

RESULTS

Twenty-four participants were interviewed, their average age was 55 years and 46% were female. We identified three themes: 'I really couldn't go there', described the physical and social barriers experienced by participants, 'It'd be really nice to let the public know there are people out there like me' expressed the desire for greater social understanding of incomplete spinal cord injury, and 'I just don't quit', displayed the perseverance that participants demonstrated following their injury.

CONCLUSION

Findings indicate service providers to improve the inclusion of ambulatory individuals with incomplete spinal cord injury in their programs. Suggestions include designing programs (community, healthcare, return to work, peer support), environments using the principles of universal design for people with incomplete spinal cord injury who ambulate, and increasing consideration of their perspectives.Implication for rehabilitation:People with incomplete spinal cord injury who can ambulate live with invisible impairments, which are often not acknowledged by family, friends, health professionals, and people with complete spinal cord injuryThey may feel excluded from activities (organized by spinal cord injury associations) that were originally designed for people with complete spinal cord injuryGreater awareness among health professionals, friends, family, and people with complete spinal cord injury of the needs of people with incomplete spinal cord injury who can ambulate is needed to increase their inclusion.

Association between Anterior Surgical Approach and Dysphagia Severity in Patients with Cervical Spinal Cord Injury

INTRODUCTION

Early detection and management of dysphagia are essential for preventing aspiration pneumonia and reducing mortality in patients with cervical spinal cord injury (C-SCI). In this study, we identified risk factors for dysphagia in patients with C-SCI by analyzing the correlation between the clinical factors and the severity of dysphagia, not the presence or absence of dysphagia. Combined with the analysis results of previous studies, we thought that this additional analysis method could more accurately reveal the risk factors for dysphagia in patients with C-SCI.

METHODS

The presence and severity of dysphagia in patients with C-SCI was evaluated using a modified videofluoroscopic dysphagia scale (mVDS) and penetration-aspiration scale (PAS). All included patients with C-SCI performed a video fluoroscopic swallowing study (VFSS). Clinical factors such as age, sex, the presence of tracheostomy, spinal cord independence measure (SCIM), pulmonary function test (PFT), including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FVC/FEV1, maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP), American Spinal Cord Injury Association (ASIA) score, Berg Balance Scale (BBS), and operation method were investigated.

RESULTS

In the multivariate regression analysis, the anterior surgical approach was the only clinical factor that had a significant correlation in both mVDS and PAS, which represents the severity of dysphagia in C-SCI patients (p < 0.05).

CONCLUSION

The anterior surgical approach was correlated with the severity of dysphagia in patients with C-SCI. Considering this, as one of the risk factors affecting dysphagia in patients with C-SCI, surgical method may also need to be considered. Additionally, we recommend that clinicians should pay particular attention to the potential for development of dysphagia in patients who received anterior cervical surgery. However, further prospective studies with larger sample sizes are needed for more accurate generalization.

Standardized administration and scoring guidelines for the Spinal Cord Independence Measure Version 3.0 (SCIM-III)

STUDY DESIGN

Qualitative studies.

OBJECTIVE

To develop clear and specific administration and scoring procedures for the Spinal Cord Independence Measure Version 3.0 as a performance-based and interview assessment.

SETTING

Research lab.

METHODS

Modified Delphi Technique survey methods were used in this study. Previously developed SCIM-III administration and scoring procedures for performance-based and interview versions were presented to clinicians experienced in SCI and SCIM-III using the Qualtrix (Qualtrics, Provo, UT) online survey platform. Summary and descriptive statistics were used to assess the percent agreement survey responses.

RESULTS

Three survey rounds were necessary to achieve 80% agreement or above for the performance-based version. Two survey rounds were necessary to achieve 80% agreement or above on the interview version.

CONCLUSIONS

This study describes the development of standardized administration and scoring procedures for the self-care and mobility sub-scales of the SCIM-III as a performance-based and interview version.

Independence and upper extremity functioning after spinal cord injury: a cross-sectional study

Upper extremity functioning is important for achieving independence in activities of daily living (ADL). A better understanding of relationships between different aspects of independence in ADL after spinal cord injury (SCI) and upper extremity functioning is required to guide rehabilitation practices. To determine which aspects of independence in ADL are correlated with upper extremity functioning in individuals with cervical or thoracic SCI. A total of 25 adults (mean age 58.4 years, 72% men) with established cervical or thoracic SCI were recruited. Independence in ADL was assessed by Spinal Cord Independence Measure (SCIM-III) and upper extremity functioning by kinematic measures (movement time, smoothness, and wrist angle during drinking task), grip strength, Upper Extremity Motor and Sensory Score, Box and Block Test (BBT), Action Research Arm Test (ARAT), and Upper Extremity Basic Data Set (ISCI-Hand and ISCI-Shoulder). Spearman correlation coefficients were used for data analyses. The SCIM-self-care subscale, particularly the feeding and dressing items, correlated moderately (r ≥ 0.5) with movement time and smoothness, grip strength, ARAT, BBT, and ISCI-Hand. The SCIM-respiration/sphincter subscale and the SCIM-mobility showed very low and low correlations with upper extremity assessments. However, at item level, respiration and bed/wheelchair mobility showed moderate correlations. Independence in self-care as domain and feeding/dressing, respiration and bed/wheelchair mobility as separate items were dependent on upper extremity functioning in individuals with cervical or thoracic SCI. Movement time and smoothness along with BBT, grip strength, ARAT, and ISCI-Hand can be used as indicators of independence in ADL. These findings can provide guidance to clinical practice in selection of upper extremity assessments in the context for ADL in individuals with SCI.

Quantifying Donor Deficits Following Nerve Transfer Surgery in Tetraplegia

PURPOSE

Nerve transfer (NT) surgery can improve function in people with cervical spinal cord injury (SCI). However, the impact of donor nerve deficits remains unclear. The purpose of this study was to quantify donor deficits experienced by individuals with cervical SCI following NT.

METHODS

This prospective single-arm, comparative study included people with SCI undergoing upper extremity NTs. Myometry was used to assess muscle strength at baseline and follow-up. The Spinal Cord Independence Measure was used to measure the ability to perform activities of daily living.

RESULTS

Ten individuals underwent 20 NTs to restore elbow extension (donor, posterior deltoid; n = 2), hand opening (donor, supinator; n = 7), and hand closing (donor, brachialis; n = 11). Shoulder abduction strength decreased (-5.6% at early and -4.5% late follow-up) in the elbow extension NT. Wrist extension strength decreased at early (-46.9% ± 30.3) and increased by late (76.4% ± 154.0) follow-up in the hand opening NT. No statistically significant change in elbow flexion strength was noted in the hand closing NT. Spinal Cord Independence Measure scores did not change significantly between baseline and early postoperative follow-up; they improved at late follow-up.

CONCLUSIONS

Use of expendable donor nerves with redundant function to perform NT surgery has relatively little impact on strength or capacity to perform activities of daily living, even in the unique and highly vulnerable SCI population. Early, temporary loss in wrist extension strength can be seen after the supinator to posterior interosseous nerve transfer. This study offers quantitative data about possible diminution of donor function after NT, enabling hand surgeons to better counsel individuals contemplating upper extremity reconstruction.

Development and validation of the sitting balance assessment for spinal cord injury (SitBASCI)

STUDY DESIGN

Multicentric psychometric study.

OBJECTIVES

The aim of this study is to introduce the development of the Sitting Balance Assessment for Spinal Cord Injury (SitBASCI) and assess its inter-rater reliability and internal consistency.

SETTING

The study was developed among the three Spinal Units of San Bortolo Hospital in Vicenza, Niguarda Hospital in Milan and AOU Careggi in Florence.

METHODS

SitBASCI is a 13-item scale developed to evaluate trunk control in individuals with SCI. Subjects were filmed while performing the 13 items of the scale. The videotapes were submitted to 25 examiners who evaluated patients' performances with the scale. The power of the study was estimated. The interclass correlational coefficient (ICC) was used to assess the inter-rater reliability of the examiner's evaluations regarding each item and the total. Cronbach's alpha was used to assess internal consistency of the scale and internal consistency of the scale on the eliminated item.

RESULTS

The study showed to have a significant power. The inter-rater reliability for the total score was p_tot = 0.997 (item's values were p = 0.876-0.998). The internal consistency of the scale was alpha = 0.925, while the internal consistency of the scale on the eliminated item was alpha = 0.912-0.930.

CONCLUSION

SitBASCI had a high inter-rater reliability and internal consistency. Items had also good inter-rater reliability and item-total correlation. Therefore, SitBASCI could be proposed as a good and reliable instrument for Italian clinicians to evaluate sitting balance and trunk control in patient with SCI despite of aetiology and level of injury.

Validity and responsiveness of the Standing and Walking Assessment Tool for sub-acute traumatic spinal cord injury

STUDY DESIGN

This is a retrospective longitudinal study.

OBJECTIVE

The Standing and Walking Assessment Tool (SWAT) combines stages of standing and walking recovery (SWAT stages) with established measures (Berg Balance Scale (BBS), 10-m walk test (10MWT), 6-min walk test (6MWT), and modified Timed Up-and-Go (mTUG)). We evaluated the SWAT's validity (known-groups and convergent) and responsiveness among inpatients with sub-acute, traumatic spinal cord injury (SCI).

SETTING

Ten Canadian rehabilitation hospitals.

METHODS

Upon admission, SWAT stage and core measures (BBS, 10MWT, 6MWT, and mTUG), International Standards for Neurological Classification of SCI sensory and motor scores, and Spinal Cord Independence Measure III (SCIM) were collected from 618 adults with SCI. Known-groups validity was evaluated by comparing SWAT stage distributions across American Spinal Injury Association Impairment Scale (AIS) classification. Convergent validity was evaluated by correlating SWAT stages with scores on other measures using Spearman's rho. The SWAT (stage and core measures) was re-administered at discharge. To evaluate responsiveness, SWAT stages at admission and discharge were compared. The standardized response mean (SRM) was used to evaluate the responsiveness of core SWAT measures.

RESULTS

The SWAT stage distribution of participants with AIS D injuries differed from those of participants with AIS A-C injuries (p ≤ 0.002). SWAT stages correlated strongly with BBS and motor scores (ρ = 0.778-0.836), and moderately with SCIM, mTUG, 10MWT, 6MWT, and sensory scores (ρ = 0.409-0.692). Discharge SWAT stage was greater than the admission stage (p < 0.0001). The BBS was the most responsive core SWAT measure (SRM = 1.26).

CONCLUSIONS

The SWAT is a valid and responsive approach to the measurement of standing and walking ability during sub-acute SCI.

Ability to detect history of falls among individuals with spinal cord injury using upper limb loading during a seated push-up test

BACKGROUND

A history of falls is an important risk factor for future falls, including for individuals with spinal cord injury (SCI) who often experience falls and subsequent injuries. This may be even more pronounced during the current COVID-19 pandemic because of the extreme shortage of hospital admission and restricted access to important services. Therefore, the ability of detecting a history of falls that can be applied to wheelchair users and ambulatory individuals with SCI in various settings are essential.

AIM

To investigate the discriminative ability of three clinical measures-the handgrip (HG) test, Spinal Cord Independence Measure (SCIM) III and Upper Limb Loading During a Seated Push-Up Test (ULL-SPUT)-in discriminating individuals with SCI with and without a history of falls over the past six months.

DESIGN

A 6-month retrospective observational cohort study.

SETTING

Inpatient tertiary rehabilitation center.

POPULATION

One hundred and fourteen wheelchair users and ambulatory individuals with SCI.

METHODS

The participants were interviewed and assessed for their demographics, SCI characteristics and fall data over the past six months, with data confirmation from related events, their caregivers and medical records. Subsequently, they were assessed using the HG test, SCIM III, and ULL-SPUT.

RESULTS

In total, 29 participants (25%) fell during the past six months (with the number of falls ranging from 1-20, with minor consequences after the falls). Among the three clinical measures assessed in this study, the ULL-SPUT data of faller participants were significantly higher than those of non-fallers (P<0.05).

CONCLUSIONS

The limited rehabilitation length and increased staying home and social isolation prompted by the COVID-19 pandemic may have reduced the fall rates of the participants. The findings suggest a higher likelihood of falls among wheelchair users and ambulatory individuals with SCI who have good mobility as determined using ULL-SPUT data.

CLINICAL REHABILITATION IMPACT

Apart from being an important rehabilitation strategy, the present findings suggest an additional benefit of ULL-SPUT to identify individuals with SCI with a likelihood of future falls. The measurement can be done easily using digital bathroom scales placing over a flat and smooth surface. Therefore, it would enable the timely initiation of fall prevention strategies in various clinical, community, home and research settings; particularly in this COVID-19 pandemic of limited beds and hospital services for these individuals.

Effect of pelvic laparoscopic implantation of neuroprosthesis in spinal cord injured subjects: a 1-year prospective randomized controlled study

STUDY DESIGN

1-year prospective RCT.

OBJECTIVE

Examine the effect of implantable pulse generator and low-frequency stimulation of the pelvic nerves using laparoscopic implantation of neuroprosthesis (LION) compared with neuromuscular electrical stimulation (NMES) in SCI.

METHODS

Inclusion criteria: traumatic spinal cord injury (SCI), age 18-55 years, neurological level-of-injury Th4-L1, time-since-injury >1 year, and AIS-grades A-B. Participants were randomized to (A) LION procedure or (B) control group receiving NMES.

PRIMARY OUTCOME MEASURE

Walking Index for Spinal Cord Injury (WISCI-II), which is a SCI specific outcome measure assessing ability to ambulate.

SECONDARY OUTCOME MEASURES

Spinal Cord Independence Measure III (SCIM III), Patient Global Impression of Change (PGIC), Penn Spasm Frequency Scale (PSFS), severity of spasticity measured by Numeric Rating Scale (NRS-11); International Spinal Cord Injury data sets-Quality of Life Basic Data Set (QoLBDS), and Brief Pain Inventory (BPI).

RESULTS

Seventeen SCI individuals, AIS grade A, neurological level ranging from Th4-L1, were randomized to the study. One individual was excluded prior to intervention. Eight participants (7 males) with a mean age (SD) of 35.5 (12.4) years were allocated to the LION procedure, 8 participants (7 males) with age of 38.8 (15.1) years were allocated to NMES. Significantly, 5 LION group participants gained 1 point on the WISCI II scale, (p < 0.013; Fisher´s exact test). WISCI II scale score did not change in controls. No significant changes were observed in the secondary outcome measures.

CONCLUSION

The LION procedure is a promising new treatment for individuals with SCI with significant one-year improvement in walking ability.

Physiotherapy using a free-standing robotic exoskeleton for patients with spinal cord injury: a feasibility study

BACKGROUND

Evidence is emerging for the use of overground lower limb robotic exoskeletons in the rehabilitation of people with spinal cord injury (SCI), with suggested benefits for gait speed, bladder and bowel function, pain management and spasticity. To date, research has focused on devices that require the user to support themselves with a walking aid. This often precludes use by those with severe trunk, postural or upper limb deficits and places the user in a suboptimal, flexed standing position. Free-standing exoskeletons enable people with higher level injuries to exercise in an upright position. This study aimed to evaluate the feasibility of therapy with a free-standing exoskeleton for those with SCI, and to determine the potential health-related benefits of this intervention.

METHODS

This 12-week intervention study with 12-week waitlist control and 12-week follow up, provided people with SCI scoring < 5 on the mobility section of the spinal cord independence measure (SCIM-III) twice weekly therapy in the REX (Rex Bionics, Auckland, NZ), a free-standing lower limb robotic exoskeleton. The primary outcome measure of interest was function, as measured on the SCIM-III. A battery of secondary outcomes was included. Participants also completed a survey on their perceptions of this treatment modality, to determine acceptability.

RESULTS

Forty-one potential participants were screened for eligibility. Two females (one ASIA A, one ASIA C) and one male (ASIA B) completed all 24 intervention sessions, and the follow up assessment. One participant showed positive trends in function, fatigue, quality of life and mood during the intervention phase. Grip and quadriceps strength, and lower limb motor function improved in another. Two improved their percentage of lean body mass during the intervention phase. Remaining results were varied across patients, time points and outcomes. The intervention was highly acceptable to all participants.

CONCLUSION

With three of 41 potential participants being eligible and completing this study, our results show that there are potential benefits of exercise in a free-standing exoskeleton for people with severe mobility impairment due to SCI, for a small subset of patients. Further research is warranted to determine those most likely to benefit, and the type of benefit depending on the patient characteristics. Trial registration The trial was registered prospectively on 20 April 2018 at www.anzctr.org.au/ (ACTRN12618000626268).

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.

Use of Regression Tree Analysis for Predicting the Functional Outcome after Traumatic Spinal Cord Injury

Predicting the long-term functional outcome after traumatic spinal cord injury (TSCI) is needed to adapt medical strategies and plan an optimized rehabilitation. This study investigates the use of regression trees for the development of predictive models based on acute clinical and demographic predictors. This prospective study was performed on 172 patients hospitalized after TSCI. Functional outcome was quantified using the Spinal Cord Independence Measure (SCIM) collected within the first-year post-injury. Age, delay before surgery, and Injury Severity Score (ISS) were considered as continuous predictors whereas energy of injury, trauma mechanisms, neurological level of injury, injury severity, occurrence of early spasticity, urinary tract infection, pressure ulcer, and pneumonia were coded as categorical inputs. A simplified model was built using only American Spinal Injury Association Impairment Scale grade, neurological level, energy, and age as predictor and was compared to a more complex model considering all 11 predictors mentioned above. The models built using 4 and 11 predictors were found to explain 51.4% and 62.3% of the variance of the SCIM total score after validation, respectively. Severity of the neurological deficit at admission was found to be the most important predictor. Other important predictors were the ISS, age, neurological level, and delay before surgery. Regression trees offer promising performances for predicting the functional outcome after a TSCI. It could help to determine the number and type of predictors leading to a prediction model of the functional outcome that can be used clinically in the future.

Clinical Protocol for Identifying and Managing Bladder Dysfunction during Acute Care after Traumatic Spinal Cord Injury

Bladder dysfunction is widespread following traumatic spinal cord injury (TSCI). Early diagnosis of bladder dysfunction is crucial in preventing complications, determining prognosis, and planning rehabilitation. We aim to suggest the first clinical protocol specifically designed to evaluate and manage bladder dysfunction in TSCI patients during acute care. A retrospective cohort study was conducted on 101 patients admitted for an acute TSCI between C1 and T12. Following spinal surgery, presence of voluntary anal contraction (VAC) was used as a criterion for removal of indwelling catheter and initiating trial of void (TOV). Absence of bladder dysfunction was determined from three consecutive post-void bladder scan residuals ≤200 mL without incontinence. All patients were reassessed 3 months post-injury using the Spinal Cord Independence Measure (SCIM). A total of 74.3% were diagnosed with bladder dysfunction during acute care, while 57.4% had a motor-complete TSCI. Three months later, 94.7% of them reported impaired bladder function. None of the patients discharged from acute care after a functional bladder was diagnosed reported impaired bladder function at the 3-month follow-up. A total of 95.7% patients without VAC had persisting impaired bladder function at follow-up. The proposed protocol is specifically adapted to the dynamic nature of neurogenic bladder function following TSCI. The assessment of VAC into the protocol provides major insight on the potential for reaching adequate bladder function during the subacute phase. Conducting TOV using bladder scan residuals in patients with VAC is a non-invasive and easy method to discriminate between a functional and an impaired bladder following acute TSCI.

Factors Associated with Recovery in Motor Strength, Walking Ability, and Bowel and Bladder Function after Traumatic Cauda Equina Injury

Traumatic cauda equina injury (TCEI) is usually caused by spine injury at or below L1 and can result in motor and/or sensory impairments and/or neurogenic bowel and bladder. We examined factors associated with recovery in motor strength, walking ability, and bowel and bladder function to aid in prognosis and establishing rehabilitation goals. The analysis cohort was comprised of persons with acute TCEI enrolled in the Rick Hansen Spinal Cord Injury Registry. Multi-variable regression analysis was used to determine predictors for lower-extremity motor score (LEMS) at discharge, walking ability at discharge as assessed by the walking subscores of either the Functional Independence Measure (FIM) or Spinal Cord Independence Measure (SCIM), and improvement in bowel and bladder function as assessed by FIM-relevant subscores. Age, sex, neurological level and severity of injury, time from injury to surgery, rehabilitation onset, and length of stay were examined as potential confounders. The cohort included 214 participants. Median improvement in LEMS was 4 points. Fifty-two percent of participants were able to walk, and >20% recovered bowel and bladder function by rehabilitation discharge. Multi-variable analyses revealed that shorter time from injury to rehabilitation admission (onset) was a significant predictor for both improvement in walking ability and bowel function. Longer rehabilitation stay and being an older female were associated with improved bladder function. Our results suggest that persons with TCEI have a reasonable chance of recovery in walking ability and bowel and bladder function. This study provides important information for rehabilitation goals setting and communication with patients and their families regarding prognosis.

An investigation into the validity and reliability of the Chinese version of Spinal Cord Independence Measure III (SCIM III)

OBJECTIVE

To investigate the validity and reliability of a Chinese version of Spinal Cord Independence Measure III (SCIM III) in individuals with spinal cord injury.

DESIGN

Study on psychometric properties.

SETTING

An inpatient rehabilitation facility in China.

SUBJECTS

102 participants with spinal cord injury. Mean (SD) age was 48.8 (15.6) years; tetraplegia/paraplegia ratio was 50/52; median time post injury was 2 months.

INTERVENTION

SCIM III was translated into Chinese. Chinese versions of Barthel Index and SCIM III were filled out for each participant by Rater 1. SCIM III was then administered by Rater 2 after 24 hours (n = 67) and 7 days (n = 65).

MAIN MEASURES

Validity, inter-rater/test-retest reliability, and internal consistency of the Chinese version of SCIM III.

RESULTS

The total scores between the two raters were similar (mean ± SD: 33.8 ± 25.8 vs 33.8 ± 25.5, P = 0.95). Total agreement between the raters in each item was >80%, with both Pearson and intraclass correlation coefficients >0.97 (P < 0.01) for each subscale and total score. The Pearson correlation coefficients of the two independent assessments performed by Rater 2 were also >0.97 (P < 0.01) for each subscale and the total score. Cronbach α was >0.7 for each subscale and the total score for both raters. High consistency was found between Barthel Index and SCIM III total scores (Pearson correlation coefficient = 0.88, P < 0.01).

CONCLUSION

The Chinese version of SCIM III is valid and reliable for the functional assessment of patients with SCI.

Return to work after spinal cord injury: a Singaporean pilot community-based rehabilitation program

STUDY DESIGN

Retrospective analysis of data collected as part of a pilot program.

OBJECTIVES

The primary objective of our study was to document the return-to-work rate of individuals with SCI who participated in a community-based interdisciplinary vocational rehabilitation program. The secondary objectives were to assess changes in their levels of community integration and functional independence.

SETTING

A community-based rehabilitation center in Singapore.

METHODS

Participants were individuals with SCI between 21 and 55 years. They identified return to work as a rehabilitation goal, and were certified fit to undergo rehabilitation by their physicians. Primary outcome was the return-to-work rate at discharge from the program. Secondary outcomes were community integration and functional independence, measured by the Community Integration Questionnaire (CIQ) and the Spinal Cord Independence Measure III (SCIM-III), respectively. We summarized participants' clinical and socio-demographic characteristics descriptively, and used inferential statistics to compare pre- and postprogram scores for secondary outcome measures.

RESULTS

Thirty-nine participants were included for this study. Thirty-two completed the program, of which 84% (n = 27) reported returning to work. Participants who completed the program had mean change in total CIQ and SCIM-III scores of 7 (95% CI, 5-8) and 11 (95% CI, 7-15), respectively. There were differences (p < 0.05) between pre- and postprogram scores for both secondary outcome measures.

CONCLUSIONS

Our findings suggest that our vocational rehabilitation program facilitated participants with SCI in Singapore to return to work and was beneficial to enhance their levels of community integration and functional independence. Future interventional studies are recommended to estimate the efficacy of such programs.

The Functional Impact of the Absence of a Bulbocavernosus Reflex in the Postoperative Period After a Motor-Complete Traumatic Spinal Cord Injury

OBJECTIVE

The aim of the study was to investigate the impact of the absence of a bulbocavernosus reflex in the postoperative period on the neurological and functional recovery 6-12 mos after a motor-complete traumatic spinal cord injury.

DESIGN

A retrospective review of a prospective database was completed among 66 patients. The functional and neurological statuses between individuals with and without a bulbocavernosus reflex were compared. A general linear model was used to investigate the association between the postoperative bulbocavernosus reflex status and the functional outcome, using the Spinal Cord Independence Measure.

RESULTS

Forty percent of the cohort had no bulbocavernosus reflex 5 days after trauma. Individuals with a bulbocavernosus reflex showed a higher rate of American Spinal Injury Association Impairment Scale grade conversion, improvement of the level of injury, and higher functional scores; however, it did not reach a significant level. The bulbocavernosus reflex status in the postoperative period was not significantly associated with the functional status 6-12 mos after injury.

CONCLUSIONS

Late recovery of the bulbocavernosus reflex in the postoperative period may be associated with poorer neurological and functional outcome for individuals sustaining a motor-complete traumatic spinal cord injury, for which the prognosis estimation is limited. A prospective study including a larger number of patients is necessary to confirm results of this study.

Lack of knowledge and training are the major obstacles in application of the Spinal Cord Independence Measure (SCIM) in China

OBJECTIVE

To investigate the use of functional outcome measurements after spinal cord injury (SCI) in current clinical practice and to explore the knowledge about the Spinal Cord Independence Measure (SCIM) among SCI physicians in China, and to find facilitators for a broader utilization of SCIM.

DESIGN

A survey-based study.

SETTING

SCI workshops at Peking University.

PARTICIPANTS

125 Chinese SCI physicians attending annual workshops in two consecutive years.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

A questionnaire was administered. The following items were included: whether functional outcome measurement for SCI individuals was performed and with which assessment tool(s); what items should be included in the assessment; whether they knew about the SCIM, its latest version, the Chinese translation, and if so from what source; the possible reasons why SCIM was not implemented in clinical practice; and whether training before using the SCIM was needed, and the training method preferred.

RESULTS

Among these physicians, 84.8% performed functional outcome measurement for individuals with SCI, but only 29.6% of attendees were aware of the SCIM and 20.8% had used it. Lack of training was the major reason why SCIM was not used in clinical practice. Furthermore, 74.4% of the physicians felt they needed formal training before using the SCIM.

CONCLUSION

The use of SCIM is limited in clinical practice in China, which is mainly attributed to lack of knowledge and training. Formal training on the use of the SCIM is essential for its dissemination and will improve functional SCI outcome measurement in China.

Transcutaneous Electrical Spinal Stimulation Promotes Long-Term Recovery of Upper Extremity Function in Chronic Tetraplegia

Upper extremity function is the highest priority of tetraplegics for improving quality of life. We aim to determine the therapeutic potential of transcutaneous electrical spinal cord stimulation for restoration of upper extremity function. We tested the hypothesis that cervical stimulation can facilitate neuroplasticity that results in long-lasting improvement in motor control. A 62-year-old male with C3, incomplete, chronic spinal cord injury (SCI) participated in the study. The intervention comprised three alternating periods: 1) transcutaneous spinal stimulation combined with physical therapy (PT); 2) identical PT only; and 3) a brief combination of stimulation and PT once again. Following four weeks of combined stimulation and physical therapy training, all of the following outcome measurements improved: the Graded Redefined Assessment of Strength, Sensation, and Prehension test score increased 52 points and upper extremity motor score improved 10 points. Pinch strength increased 2- to 7-fold in left and right hands, respectively. Sensation recovered on trunk dermatomes, and overall neurologic level of injury improved from C3 to C4. Most notably, functional gains persisted for over 3 month follow-up without further treatment. These data suggest that noninvasive electrical stimulation of spinal networks can promote neuroplasticity and long-term recovery following SCI.

Interrater Reliability of the Pediatric Neuromuscular Recovery Scale for Spinal Cord Injury

Background: In synergy with the mounting scientific evidence for the capacity of recovery after spinal cord injury (SCI) and training, new evidence-based therapies advancing neuromuscular recovery are emerging. There is a parallel need for outcome instruments that specifically address recovery. The Pediatric Neuromuscular Recovery Scale (Pediatric NRS) is one example with established content validity to assess neuromuscular capacity within task performance. Objective: The objective of this study was to determine interrater reliability of the Pediatric NRS to classify motor capacity in children after SCI. Methods: Pediatric physicians (3), occupational therapists (5), and physical therapists (6) received standardized training in scoring the scale, then rated video assessments of 32 children post SCI, 2-12 years of age, 78% non-ambulatory. Interrater reliability was analyzed using Kendall coefficient of concordance for individual Pediatric NRS items and overall score. Results: The interrater reliability coefficient was determined to be near 1 for the overall Pediatric NRS score (ICC = 0.966; 95% CI, 0.89-0.98). Twelve of 16 individual items exhibited high concordance coefficients (Kendall's W ≥ 0.8) and four items demonstrated concordance coefficients, < 0.8 and > 0.69. Interrater reliability was equivalent among groups defined by age and neurological level, but lower among non-ambulatory individuals. Conclusion: Strong interrater reliability was demonstrated by pediatric clinicians who scored children with SCI using the Pediatric NRS.

Activity-Based Therapy in a Community Setting for Independence, Mobility, and Sitting Balance for People With Spinal Cord Injuries

INTRODUCTION

Activity-based therapy (ABT) aims to activate the neuromuscular system below the level of the spinal cord lesion and promote recovery of motor tasks through spinal reorganisation, motor learning and changes to muscles and sensory system. We investigated the effects of a multimodal ABT program on mobility, independence and sitting balance in individuals with spinal cord injury (SCI).

METHODS

Retrospective clinical data from 91 adults who independently enrolled in four community-based ABT centres in Australia were analysed. The multimodal ABT program was delivered for 3 to 12 months, one to four times per week. Assessments were undertaken every 3 months and included the Modified Rivermead Mobility Index (MRMI), Spinal Cord Independence Measure (SCIM) and seated reach distance (SRD). A linear mixed model analysis was used to determine time-based and other predictors of change.

RESULTS

There was a significant improvement after 12 months for all outcome measures, with a mean change score of 4 points in the SCIM (95% confidence interval [CI]: 2.7-5.3, d = 0.19), 2 points in the MRMI (95% CI: 1-2.3, d = 0.19) and 0.2 in the SRD (95% CI: 0.1-2.2, d = 0.52). Greater improvements occurred in the first 3 months of intervention. There were no interaction effects between time and the neurological level of injury, American Spinal Injury Association Impairment Scale classification, or duration post-injury for most outcomes.

CONCLUSIONS

A community-based ABT exercise program for people with SCI can lead to small improvements in mobility, independence and balance in sitting, with greater improvements occurring early during intervention.

Is admission to an SCI specialized rehabilitation facility associated with better functional outcomes? Analysis of data from the Thai Spinal Cord Injury Registry

STUDY DESIGN

Prospective cohort study of the Thai Spinal Cord Injury Registry.

OBJECTIVE

To determine whether being admitted to a spinal cord injury (SCI) specialized rehabilitation facility (SSRF) is associated with better functional outcomes.

SETTING

Four rehabilitation facilities in Thailand; one a SSRF and the others non-SSRFs.

METHODS

Data from the one SSRF and three non-SSRFs were extracted from the Thai Spinal Cord Injury Registry. Multivariate regression analysis was used to exclude the effect of confounding factors and prove the independent association of SSRF admission with respect to Spinal Cord Independence Measurement (SCIM) at discharge.

RESULTS

Among the 234 new SCI inpatients enrolled, 167 persons (71%) had been admitted to the SSRF. The SSRF had a greater proportion of persons with AIS A, B, C tetraplegia and people with AIS D, whereas the non-SSRFs had a higher proportion of patients with AIS A, B or C paraplegia. Patients discharged from the SSRF demonstrated a greater SCIM score improvement than those from the non-SSRFs (24.1 vs 17.0; p = 0.003). By using multivariate regression analysis controlling for age, time from injury to rehabilitation, severity of injury and SCIM score on admission, SSRF admission was found to be an independent predictive factor of SCIM score improvement at discharge (p = 0.008).

CONCLUSION

Admission to an SSRF is associated with better rehabilitation outcomes. This finding supports the importance of SSRF access to improve the functional outcome of patients with SCI.

Functional independence of persons with long-standing motor complete spinal cord injury in the Netherlands

Context/Objective: Since life expectancy of persons with spinal cord injury (SCI) has improved, it is relevant to know whether this group is able to maintain functional abilities many years after onset of SCI. Objectives of this study were (1) to examine associations between time since injury (TSI) and functional independence in persons with long-standing SCI and (2) to explore associations between functional independence and level of injury, comorbidities, mental health, waist circumference and secondary health conditions (SHCs).Design: TSI-stratified cross-sectional study. Strata were 10-19, 20-29 and 30+ years.Setting: Community.Participants: 226 persons with long-standing SCI. Inclusion criteria: motor complete SCI; age at injury 18-35 years; TSI ≥ 10 years; current age 28-65 years; wheelchair dependency.Interventions: Not applicable.Outcome measures: The Spinal Cord Independence Measure III (SCIM) was administered by a trained research assistant. Level of injury, comorbidities, mental health, waist circumference and SHCs were assessed by a rehabilitation physician.Results: Mean TSI was 23.6 (SD 9.1) years. No significant differences in SCIM scores were found between TSI strata. SCIM scores were lower for persons with tetraplegia, autonomic dysreflexia, hypotension, more than four SHCs and a high waist circumference. In linear regression analyses, TSI nor age was associated with the SCIM total score. Only level of injury (β = -0.7; P < .001) and waist circumference (β = -0.1; P = .042) were independent determinants (explained variance 55%).Conclusion: We found no association between TSI and functional independence in persons with long-standing motor complete SCI. This study confirms the possible effect of overweight on functional independence.

Strengthening Health Systems for Persons With Traumatic Spinal Cord Injury in South Africa and Sweden: A Protocol for a Longitudinal Study of Processes and Outcomes

Background: The provision of specialized care in a time-sensitive manner has shown to be crucial for survival and recovery of functioning after a traumatic spinal cord injury (TSCI). However, little is known about the provision of TSCI care in different international contexts; information which is required for strengthening policy and practice.

Aims: The overarching aim of this study will be to explore health care processes and outcomes of TSCI care in South Africa and Sweden. Specific aims will be to: (1) describe acute processes of TSCI care, (2) determine acute- and long-term outcomes of TSCI care, and (3) identify predictors for survival, secondary complications, and functioning 12 months post-injury.

Methods: A prospective (regional), population-based cohort study where adults with an acute TSCI will be recruited over at least a 1-year period from the City of Cape Town, South Africa, and Stockholm, Sweden. The anticipated sample size inclusive of both international contexts will be 200 participants—based on a power calculation for detecting differences in mortality. Information on the nature and timing of processes of acute care (e.g., transfer logistics, spinal surgery, and specialized SCI care) will be collected on acute care admission and discharge using a standardized form. Survival status, secondary complications, neurological symptoms, functional status, activity, and participation as well as health-related quality of life will be collected at discharge from SCI acute care and at 12-months post-injury. Secondary complications and functioning will be compared between South Africa and Sweden using inferential statistics. To address mortality specifically, the indirect standardization method for differences in mortality between contexts will be used whereby Stockholm will serve as standard for specialize care. For the assessment of factors related to mortality and other outcomes (e.g., neurological and secondary health conditions) multivariate regression analyses will be used to determine independent risk factors.

Conclusion: This study offers a unique investigation of the relationship between health care processes and outcomes of TSCI care with the aim of strengthening management guidelines for SCI in South Africa and Sweden.

Rho Inhibitor VX-210 in Acute Traumatic Subaxial Cervical Spinal Cord Injury: Design of the SPinal Cord Injury Rho INhibition InvestiGation (SPRING) Clinical Trial

Traumatic spinal cord injury (SCI) is associated with a lifetime of disability stemming from loss of motor, sensory, and autonomic functions; these losses, along with increased comorbid sequelae, negatively impact health outcomes and quality of life. Early decompression surgery post-SCI can enhance patient outcomes, but does not directly facilitate neural repair and regeneration. Currently, there are no U.S. Food and Drug Administration-approved pharmacological therapies to augment motor function and functional recovery in individuals with traumatic SCI. After an SCI, the enzyme, Rho, is activated by growth-inhibitory factors and regulates events that culminate in collapse of the neuronal growth cone, failure of axonal regeneration, and, ultimately, failure of motor and functional recovery. Inhibition of Rho activation is a potential treatment for injuries such as traumatic SCI. VX-210, an investigational agent, inhibits Rho. When administered extradurally after decompression (corpectomy or laminectomy) and stabilization surgery in a phase 1/2a study, VX-210 was well tolerated. Here, we describe the design of the SPRING trial, a multicenter, phase 2b/3, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of VX-210 (NCT02669849). A subset of patients with acute traumatic cervical SCI is currently being enrolled in the United States and Canada. Medical, neurological, and functional changes are evaluated at 6 weeks and at 3, 6, and 12 months after VX-210 administration. Efficacy will be assessed by the primary outcome measure, change in upper extremity motor score at 6 months post-treatment, and by secondary outcomes that include question-based and task-based evaluations of functional recovery.

Despite limitations in content range, the SCIM-III is reproducible and a valid indicator of physical function in youths with spinal cord injury and dysfunction

STUDY DESIGN

Multi-center, repeated measures OBJECTIVES: Evaluate psychometric properties of the SCIM-III in children.

SETTING

Seven facilities in North America METHODS: One-hundred and twenty-seven youths, mean age of 10.8 years and chronic spinal cord injury/dysfunction completed two administrations of the Spinal Cord Independence Measure-III (SCIM-III). Mean, standard deviation, range values were calculated for SCIM-III total and subscales for the entire sample, four age groups and injury characteristics. Test-retest reliability, concurrent validity, and floor and ceiling effects were examined.

RESULTS

Total SCIM-III and self-care (SC) subscale scores for the youngest age group were lower than those for the three older age groups. There were statistically significant differences in SC subscale scores between neurological level (NL) C5-T1 and T2 -T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5 and in in-room, and indoor/outdoor mobility subscale scores between C1-C4 and T2-T12; C1-C4 and L1-S4/5; C5-T1 and T2-T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5. All scores between motor complete and motor incomplete differed. Test-retest reliability was good (ICC values = > 0.84) and there was moderate to strong correlation between SCIM-III and the FIM® Instrument (r = 0.77-0.92). Ceiling effects were present in the SC subscale for the oldest age group (24%) and for NL L1-S4/5 (35.5%) and in in-room mobility subscale for 6-12 (45.7%), 13-15 (30.43%) and 16-17 (60%) ages, paraplegia (42.4%), tetraplegia (37.1%), incomplete injuries (50%), and T2-T12 (38%) and L1-S4/5 (100%) NL.

CONCLUSION

Despite limitations in content range, the SCIM-III is reproducible, and a valid indicator of physical functioning in youth with SCI/D 6 years of age and older.

Management of acute traumatic spinal cord injuries

Acute traumatic spinal cord injury (SCI) is a devastating disease process affecting tens of thousands of people across the USA each year. Despite the increase in primary prevention measures, such as educational programs, motor vehicle speed limits, automobile running lights, and safety technology that includes automobile passive restraint systems and airbags, SCIs continue to carry substantial permanent morbidity and mortality. Medical measures implemented following the initial injury are designed to limit secondary insult to the spinal cord and to stabilize the spinal column in an attempt to decrease devastating sequelae. This chapter is an overview of the contemporary management of an acute traumatic SCI patient from the time of injury through the stay in the intensive care unit. We discuss initial triage, immobilization, and transportation of the patient by emergency medical services personnel to a definitive treatment facility. Upon arrival at the emergency department, we review initial trauma protocols and the evidence-based recommendations for radiographic evaluation of the patient's vertebral column. Finally, we outline closed cervical spine reduction and various aggressive medical therapies aimed at improving neurologic outcome.

Mapping two measures to the International Classification Of Functioning, Disability and Health and the brief ICF core set for spinal cord injury in the post-acute context

OBJECTIVE

To evaluate the extent to which the rehabilitation outcome levels (ROL) and the spinal cord independence measure (SCIM) III could be mapped to the International Classification of Functioning, Disability and Health (ICF) and the brief core set for spinal cord injury (SCI) in the post-acute context.

METHODS

Two professionals used the published protocol to map the concepts derived from both measures to the ICF categories. Further, the endorsed categories at the second level of the ICF were used to determine the coverage of the Brief ICF Core Set for SCI.

RESULTS

Three items of the ROL could not be conceptualised within the ICF, while the rest were mapped to 42 second-level categories, mainly to the activity and participation domain. All the items of the SCIM III were mapped, yielding 52 ICF categories, mostly at the third level (32). For the mapping to the Core Set for SCI, the ROL covered five and the SCIM III all nine categories of 'activities and participation' included as the candidate categories of the brief version.

CONCLUSION

In terms of content, the ROL appears to be a more global measure of functioning, compared with the SCIM III that covers specific 'activity' aspects as proposed in the Brief Core Set for SCI. It is thus recommended that standardised measures, such as the SCIM III, be used due to its conceptual underpinnings and coverage of important aspects. Implications for Rehabilitation Rehabilitation professionals should select appropriately validated outcome measures specific to the health condition in order to evaluate the effectiveness of rehabilitation. Rehabilitation professional working with outcome measures should be aware of the limitations of measures, in terms of content, and supplement the evaluation with appropriate standardised measures or the use of the Core Sets. To enhance evidence-based practise in routine clinical practise, standardised outcome measures should be used.

The influence of shoulder pain on functional limitation, perceived health, and depressive mood in patients with traumatic paraplegia

OBJECTIVE

To assess whether functional activity, perceived health, and depressive symptoms differ between individuals with traumatic paraplegia with and without shoulder pain.

DESIGN

Cross sectional and comparative investigation using the unified questionnaire.

SETTING

Neural Regeneration and Repair Division unit of Taipei Veterans General Hospital in Taiwan.

PARTICIPANTS

Seventy-six patients with paraplegia (23 with and 53 without shoulder pain) who had experienced spinal cord injury at American Spinal Injury Association Impairment Scale T2 to T12 neurologic level (at least 6 months previously).

OUTCOME MEASURES

Spinal Cord Independence Measure (SCIM), a single item from the Medical Outcomes Study 36-Item Short-Form Health Survey, and Patient Health Questionnaire-9 (PHQ-9) depression scale.

RESULTS

Shoulder pain was prevalent in 30% patients. Patients with shoulder pain had significantly worse perceived health and greater depressive symptoms than those without. No significant difference was found in functional ability between groups. Greater shoulder pain intensity was related to higher depressive scores (r=0.278, P=0.017) and lower self-perceived health scores (r=-0.433, P<0.001) but not SCIM scores (P=0.342).

CONCLUSION

Although shoulder pain was unrelated to functional limitation, it was associated with lower perceived health and higher depressive mood levels.

The spinal cord independence measure (SCIM)-III self report for youth

STUDY DESIGN

The items and response scales of the Spinal Cord Independence Measure (SCIM-III) self report (SR) were exposed to formal cognitive testing with children with SCI, and in parallel a survey using the modified Delphi Technique was conducted to engage content experts in an iterative critical review of the SCIM-III SR.

OBJECTIVES

To evaluate the validity of the SCIM-III SR for pediatric utilization.

SETTING

United States of America.

METHODS

Formal cognitive testing was conducted with 17 youths with SCI and required them to read and answer each SCIM-III SR item aloud. Think aloud methodology was used to record details about how youths understood and interpreted items and why they selected a given response. The interviews were audiotaped and transcribed verbatim. Content analysis focused on identifying words that children could not read or understand. In parallel, the Modified Delphi Technique engaged expert therapists to critically review the SCIM-III SR for pediatric utilization.

RESULTS

Every SCIM-III SR item and response scale required modification before children were able to read, understand and respond to them. Youth encountered difficulties because of vague terms, medical jargon and complex words and phrases. Three iterative Delphi rounds were required before achieving 80% agreement that items and response scales were written well for children.

CONCLUSION

Our findings informed modifications to every SCIM-III SR item and response scale, producing a pediatric version of the tool that we formally refer to as the SCIM-III SR-Youth (SCIM-III SR-Y).
