Effectiveness of a Self-Management Intervention to Promote an Active Lifestyle in Persons With Long-Term Spinal Cord Injury: The HABITS Randomized Clinical Trial

Invasive Brain Computer Interface for Motor Restoration in Spinal Cord Injury: A Systematic Review

STUDY DESIGN

Systematic review of the literature.

OBJECTIVES

In recent years, brain-computer interface (BCI) has emerged as a potential treatment for patients with spinal cord injury (SCI). This is the first systematic review of the literature on invasive closed-loop BCI technologies for the treatment of SCI in humans.

MATERIALS AND METHODS

A comprehensive search of PubMed MEDLINE, Web of Science, and Ovid EMBASE was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Of 8316 articles collected, 19 studies met all the inclusion criteria. Data from 21 patients were extracted from these studies. All patients sustained a cervical SCI and were treated using either a BCI with intracortical microelectrode arrays (n = 18, 85.7%) or electrocorticography (n = 3, 14.3%). To decode these neural signals, machine learning and statistical models were used: support vector machine in eight patients (38.1%), linear estimator in seven patients (33.3%), Hidden Markov Model in three patients (14.3%), and other in three patients (14.3%). As the outputs, ten patients (47.6%) underwent noninvasive functional electrical stimulation (FES) with a cuff; one (4.8%) had an invasive FES with percutaneous stimulation, and ten (47.6%) used an external device (neuroprosthesis or virtual avatar). Motor function was restored in all patients for each assigned task. Clinical outcome measures were heterogeneous across all studies.

CONCLUSIONS

Invasive techniques of BCI show promise for the treatment of SCI, but there is currently no technology that can restore complete functional autonomy in patients with SCI. The current techniques and outcomes of BCI vary greatly. Because invasive BCIs are still in the early stages of development, further clinical studies should be conducted to optimize the prognosis for patients with SCI.

Transcriptome Profiling after Early Spinal Cord Injury in the Axolotl and Its Comparison with Rodent Animal Models through RNA-Seq Data Analysis

BACKGROUND

Traumatic spinal cord injury (SCI) is a disabling condition that affects millions of people around the world. Currently, no clinical treatment can restore spinal cord function. Comparison of molecular responses in regenerating to non-regenerating vertebrates can shed light on neural restoration. The axolotl (Ambystoma mexicanum) is an amphibian that regenerates regions of the brain or spinal cord after damage.

METHODS

In this study, we compared the transcriptomes after SCI at acute (1-2 days after SCI) and sub-acute (6-7 days post-SCI) periods through the analysis of RNA-seq public datasets from axolotl and non-regenerating rodents.

RESULTS

Genes related to wound healing and immune responses were upregulated in axolotls, rats, and mice after SCI; however, the immune-related processes were more prevalent in rodents. In the acute phase of SCI in the axolotl, the molecular pathways and genes associated with early development were upregulated, while processes related to neuronal function were downregulated. Importantly, the downregulation of processes related to sensorial and motor functions was observed only in rodents. This analysis also revealed that genes related to pluripotency, cytoskeleton rearrangement, and transposable elements (e.g., Sox2, Krt5, and LOC100130764) were among the most upregulated in the axolotl. Finally, gene regulatory networks in axolotls revealed the early activation of genes related to neurogenesis, including Atf3/4 and Foxa2.

CONCLUSIONS

Immune-related processes are upregulated shortly after SCI in axolotls and rodents; however, a strong immune response is more noticeable in rodents. Genes related to early development and neurogenesis are upregulated beginning in the acute stage of SCI in axolotls, while the loss of motor and sensory functions is detected only in rodents during the sub-acute period of SCI. The approach employed in this study might be useful for designing and establishing regenerative therapies after SCI in mammals, including humans.

Exercise and aerobic capacity in individuals with spinal cord injury: A systematic review with meta-analysis and meta-regression

BACKGROUND

A low level of cardiorespiratory fitness [CRF; defined as peak oxygen uptake ([Formula: see text]O2peak) or peak power output (PPO)] is a widely reported consequence of spinal cord injury (SCI) and a major risk factor associated with chronic disease. However, CRF can be modified by exercise. This systematic review with meta-analysis and meta-regression aimed to assess whether certain SCI characteristics and/or specific exercise considerations are moderators of changes in CRF.

METHODS AND FINDINGS

Databases (MEDLINE, EMBASE, CENTRAL, and Web of Science) were searched from inception to March 2023. A primary meta-analysis was conducted including randomised controlled trials (RCTs; exercise interventions lasting >2 weeks relative to control groups). A secondary meta-analysis pooled independent exercise interventions >2 weeks from longitudinal pre-post and RCT studies to explore whether subgroup differences in injury characteristics and/or exercise intervention parameters explained CRF changes. Further analyses included cohort, cross-sectional, and observational study designs. Outcome measures of interest were absolute (A[Formula: see text]O2peak) or relative [Formula: see text]O2peak (R[Formula: see text]O2peak), and/or PPO. Bias/quality was assessed via The Cochrane Risk of Bias 2 and the National Institute of Health Quality Assessment Tools. Certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Random effects models were used in all meta-analyses and meta-regressions. Of 21,020 identified records, 120 studies comprising 29 RCTs, 67 pre-post studies, 11 cohort, 7 cross-sectional, and 6 observational studies were included. The primary meta-analysis revealed significant improvements in A[Formula: see text]O2peak [0.16 (0.07, 0.25) L/min], R[Formula: see text]O2peak [2.9 (1.8, 3.9) mL/kg/min], and PPO [9 (5, 14) W] with exercise, relative to controls (p < 0.001). Ninety-six studies (117 independent exercise interventions comprising 1,331 adults with SCI) were included in the secondary, pooled meta-analysis which demonstrated significant increases in A[Formula: see text]O2peak [0.22 (0.17, 0.26) L/min], R[Formula: see text]O2peak [2.8 (2.2, 3.3) mL/kg/min], and PPO [11 (9, 13) W] (p < 0.001) following exercise interventions. There were subgroup differences for R[Formula: see text]O2peak based on exercise modality (p = 0.002) and intervention length (p = 0.01), but there were no differences for A[Formula: see text]O2peak. There were subgroup differences (p ≤ 0.018) for PPO based on time since injury, neurological level of injury, exercise modality, and frequency. The meta-regression found that studies with a higher mean age of participants were associated with smaller changes in A[Formula: see text]O2peak and R[Formula: see text]O2peak (p < 0.10). GRADE indicated a moderate level of certainty in the estimated effect for R[Formula: see text]O2peak, but low levels for A[Formula: see text]O2peak and PPO. This review may be limited by the small number of RCTs, which prevented a subgroup analysis within this specific study design.

CONCLUSIONS

Our primary meta-analysis confirms that performing exercise >2 weeks results in significant improvements to A[Formula: see text]O2peak, R[Formula: see text]O2peak, and PPO in individuals with SCI. The pooled meta-analysis subgroup comparisons identified that exercise interventions lasting up to 12 weeks yield the greatest change in R[Formula: see text]O2peak. Upper-body aerobic exercise and resistance training also appear the most effective at improving R[Formula: see text]O2peak and PPO. Furthermore, acutely injured, individuals with paraplegia, exercising for ≥3 sessions/week will likely experience the greatest change in PPO. Ageing seemingly diminishes the adaptive CRF responses to exercise training in individuals with SCI.

Mesenchymal Stem Cell Therapy in Traumatic Spinal Cord Injury: A Systematic Review

Recovery from a traumatic spinal cord injury (TSCI) is challenging due to the limited regenerative capacity of the central nervous system to restore cells, myelin, and neural connections. Cell therapy, particularly with mesenchymal stem cells (MSCs), holds significant promise for TSCI treatment. This systematic review aims to analyze the efficacy, safety, and therapeutic potential of MSC-based cell therapies in TSCI. A comprehensive search of PUBMED and COCHRANE databases until February 2023 was conducted, combining terms such as "spinal cord injury," "stem cells," "stem cell therapy," "mesenchymal stem cells," and "traumatic spinal cord injury". Among the 53 studies initially identified, 22 (21 clinical trials and 1 case series) were included. Findings from these studies consistently demonstrate improvements in AIS (ASIA Impairment Scale) grades, sensory scores, and, to a lesser extent, motor scores. Meta-analyses further support these positive outcomes. MSC-based therapies have shown short- and medium-term safety, as indicated by the absence of significant adverse events within the studied timeframe. However, caution is required when drawing generalized recommendations due to the limited scientific evidence available. Further research is needed to elucidate the long-term safety and clinical implications of these advancements. Although significant progress has been made, particularly with MSC-based therapies, additional studies exploring other potential future therapies such as gene therapies, neurostimulation techniques, and tissue engineering approaches are essential for a comprehensive understanding of the evolving TSCI treatment landscape.

Effects of behaviour change interventions on physical activity in people with spinal cord injury: A systematic review and meta-analysis

OBJECTIVES

This review investigated the effectiveness of behaviour-change interventions to improve physical activity (PA) participation in individuals with a spinal cord injury. Additionally, the review sought to analyse the change in PA behaviour that might be expected by utilising behaviour change in PA interventions and what specific intervention characteristics, application of behaviour change theories, and behaviour change techniques are most efficacious.

METHODS

The protocol was prospectively registered on PROSPERO: CRD42021252744, and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed in this review. Eight databases were comprehensively searched using a well-defined strategy developed in collaboration with an academic liaison librarian. Randomised, non-randomised controlled, and non-controlled studies were included in this review; however, controlled and non-controlled studies were analysed separately. Studies were included if participants were older than 16 years and had an SCI of any cause, level or severity, regardless of the time since injury. The behaviour change technique taxonomy version 1 was used to code the intervention characteristics for behaviour modification. The combined effects across studies were pooled in a meta-analysis, and the risk of bias was assessed using the Cochrane Risk of Bias 2 tool.

RESULTS

The search retrieved 10,155 titles and abstracts. After duplicate removal and screening against the eligibility criteria, 23 studies were included. The overall effect estimate of the change in PA participation in the controlled trials post-intervention was medium (d = 0.50, 95% CI = 0.31-0.70) in favour of behaviour-targeted interventions. The mean difference in PA volume between pre- and post-intervention was an increase of 22 minutes per week (95% CI = 5.96-38.90). Interventions that provided practical support (d = 0.81, 95% CI = 0.46-1.16), which were individualised (d = 0.62, 95% CI = 0.34-0.90) and that utilised monitoring (d = 0.59, 95% CI = 0.34-0.83) had a greater effect on change to PA than those that were group-based and did not utilise those specific techniques.

CONCLUSIONS

Interventions that target behaviour change to increase PA in people with SCI appear effective. Utilising behaviour change frameworks and specific behaviour change techniques augments PA uptake and levels, and interventions aimed at improving PA in people with SCI should incorporate a behaviour modification component. More research is needed on the isolated effect of intervention structure parameters and specific behaviour change techniques.

Lifestyle assessment in individuals with spinal cord injuries caused by accidents and disasters in qualitative studies published from 1990 to 2020: A meta-synthesis of qualitative study

Background and Aims

As a debilitating disorder, spinal cord injuries (SCIs) can bring about a range of physical, psychological, and social consequences in individuals and even have effects on their lifestyle indicators. The present study was thus to reflect on lifestyles among people with SCIs developing from accidents and disasters.

Methods

Using a meta-synthesis of qualitative research, all articles recruiting qualitative methods to examine patients with SCIs, published from 1990 to 2020, were retrieved by the researchers, good at the Persian and English languages, from the databases of ScienceDirect, MD Consult, Pedro, ProQuest, PubMed, SID, MedLib, Magiran, Scopus, Google Scholar, Iranmedex, the Cochran Library, CINAHL, and Blackwell, tapping the keywords of "spinal cord injury, SCI, manmade disaster, natural disaster, content analysis, concept analysis, thematic analysis, lifestyle, quality of life, QoL, grounded theory, meta-synthesis, mixed-methods research, historical research, ethnography, and phenomenology" in both languages for their inclusion in this study and further analyses.

Results

With reference to the inclusion criteria, 18 articles were extracted, and after all 10 studies in line with the research topic were reviewed and analyzed. Ultimately, six main themes, namely, compromise, self-reliance, income-generating activities, mental status, inability, and issues of sexuality were extracted, demonstrating their importance to individuals suffering from SCIs.

Conclusion

During the initial stages following SCIs, the abilities to engage in participatory practices and individual's power of decision-making diminish because of physical, social, psychological, and environmental constraints. It was accordingly recommended to have a holistic perspective and respect all aspects of life in individuals with SCIs.

Physical activity promotion to persons with spinal cord injury by health and exercise professionals: A scoping review

OBJECTIVES

Health and exercise professionals (HEPs) are ideal promoters and valued messengers of physical activity (PA) information among persons with spinal cord injury (SCI). However, little is known about what strategies used by HEPs increase PA behavior in persons with SCI, or what factors influence HEPs when promoting PA to persons with SCI. The purposes of this scoping review were to (1) ascertain the extent, range and nature of the literature, (2) identify strategies used by HEPs that are associated with an increase in PA behavior for persons with SCI, and (3) identify the facilitators and barriers to PA promotion by the HEPs.

METHODS

A comprehensive search was undertaken. Search terms were expanded surrounding three key terms: PA, promotion, and SCI.

RESULTS

Twenty-four articles representing 18 unique studies were identified. HEPs predominantly consisted of physiotherapists, occupational therapists, and leisure trainers/therapists. Most interventions were delivered by HEPs to persons with SCI in in-patient rehabilitation centres and community-based settings. Tailored exercise programs and on-going counseling support were considered essential for increasing PA behavior. HEPs' common barriers to PA promotion were perceived lack of time, education, and training.

CONCLUSION

A need to improve and sustain SCI-specific PA knowledge and education was identified if PA promotion is to become a structured and integral component of practice. This study provides valuable information for interventions to increase PA behavior among persons with SCI by improving PA promotion by HEPs.

Physical activity programs for cardiovascular outcomes in community wheelchair users: A systematic review

Purpose

Physical inactivity is one of the important factors leading to chronic diseases including cardiovascular disease (CVD) in individuals with disabilities. However, not many Physical Activity (PA) interventions are available for improving the efficacy of PA and cardiovascular outcomes among community wheelchair users. Therefore, this systematic review will appraise the existing PA interventions for the community dwelling wheelchair users; we especially examined features of the PA programs that showed the improvements in PA and the CVD outcomes compared to the interventions that did not show any improvements in these outcomes among these population. The study also aimed to provide some recommendations for future research.

Materials and Methods

A comprehensive and systematic search of literature published between 2015 and 2020 using the databases Scopus, Pubmed, Embase, and Cochrane CENTRAL was conducted. This review has followed the Preferred Reporting Items for Systematic Review (PRISMA) guidelines. The quality of the evidence was assessed by Using Joanna Briggs Institute's critical appraisal tool. Studies that tested the efficacy of PA interventions for community-dwelling adult wheelchair users and published in English were involved. Two reviewers reviewed the literature and any disagreements among these reviewers were resolved by a third reviewer.

Results

Fourteen articles were selected for this review. Most of the studies reported improvements in PA. A few studies followed up the participants and majority of the studies have looked at the CVD outcomes.

Conclusion

Large-scale studies with follow-ups, and community participatory research that evaluates the effect of PA interventions on PA and CVD outcomes among wheelchair users are needed.

Self-Management Embedded in Daily Activities: A Photoelicitation Focus Group Study among Persons with Spinal Cord Injury and Their Primary Caregivers in Bangladesh

Purpose

This study explored how community-dwelling persons with spinal cord injury (SCI) and their primary caregivers execute self-management strategies in daily activities. These strategies were mapped to a preexisting self-management framework.

Methods

Photoelicitation focus group discussions were conducted among 14 adults with SCI and their primary caregivers (in two groups). Moreover, a constant comparative framework was used to analyze the data.

Results

This study identified nine groups of self-management strategies, some of which could not be categorized under the three main self-management components generally accepted in the literature. Accordingly, a new component is proposed based off of this analysis, entitled management of social complexities, which includes crucial strategies such as (1) relocating to another environment, (2) behaving in an assertive manner, and (3) advocating for social change.

Conclusion

The results show that self-management, traditionally described as medical, emotional, and role management, should also include the management of social complexities. The identified strategies could be considered in the development of self-management enhancement programs in lower-middle-income countries.

Spinal Cord Injury: A Systematic Review and Network Meta-Analysis of Therapeutic Strategies Based on 15 Types of Stem Cells in Animal Models

Objective: The optimal therapeutic strategies of stem cells for spinal cord injury (SCI) are fully explored in animal studies to promote the translation of preclinical findings to clinical practice, also to provide guidance for future animal experiments and clinical studies.

Methods: PubMed, Web of Science, Embase, CNKI, Wangfang, VIP, and CBM were searched from inception to September 2021. Screening of search results, data extraction, and references quality evaluation were undertaken independently by two reviewers.

Results and Discussion: A total of 188 studies were included for data analysis. Results of traditional meta-analysis showed that all 15 diverse types of stem cells could significantly improve locomotor function of animals with SCI, and results of further network meta-analysis showed that adipose-derived mesenchymal stem cells had the greatest therapeutic potential for SCI. Moreover, a higher dose (≥1 × 106) of stem cell transplantation had better therapeutic effect, transplantation in the subacute phase (3–14 days, excluding 3 days) was the optimal timing, and intralesional transplantation was the optimal route. However, the evidence of current animal studies is of limited quality, and more high-quality research is needed to further explore the optimal therapeutic strategies of stem cells, while the design and implementation of experiments, as well as measurement and reporting of results for animal studies, need to be further improved and standardized to reduce the risk when the results of animal studies are translated to the clinic.

Lifestyle physical activity in manual wheelchair users - an overlooked public health opportunity

Public health guidelines and health promotion efforts have traditionally focused on weekly accumulation of moderate to vigorous physical activity (MVPA) via structured exercise. There has been a recent paradigm shift towards the organic incorporation of MVPA in daily leisure and non-leisure time, termed "Lifestyle Physical Activity" (LPA). However, this paradigm shift and the underlying research has neglected manual wheelchair users (MWCUs) with spinal cord injury (SCI), who could benefit from LPA. This article argues for expanding the LPA paradigm shift into research and health promotion efforts involving MWCUs with SCI. We suggest a working definition of LPA for MWCUs and candidate metrics for quantifying LPA. This is followed by brief overviews of LPA correlates, outcomes/consequences, and interventions and the need for theory based approaches to study these domains. We lastly suggest an approach for mitigating potential negative outcomes of increased LPA in MWCUs and suggest a research agenda.

Current evidence on mesenchymal stem cell therapy for traumatic spinal cord injury: systematic review and meta-analysis

BACKGROUND AIMS

The authors aim to analyze the evidence in the literature regarding the efficacy and safety of mesenchymal stem cell (MSC) therapy in human subjects with traumatic spinal cord injury (SCI) and identify its potential role in the management of SCI.

METHODS

The authors conducted independent and duplicate searches of electronic databases, including PubMed, Embase and the Cochrane Library, until May 2020 for studies analyzing the efficacy and safety of stem cell therapy for SCI. American Spine Injury Association (ASIA) impairment scale (AIS) grade improvement, ASIA sensorimotor score, activities of daily living score, residual urine volume, bladder function improvement, somatosensory evoked potential (SSEP) improvement and adverse reactions were the outcomes analyzed. Analysis was performed in R platform using OpenMeta[Analyst] software.

RESULTS

Nineteen studies involving 670 patients were included for analysis. On analysis, the intervention group showed statistically significant improvement in AIS grade (P < 0.001), ASIA sensory score (P < 0.017), light touch (P < 0.001), pinprick (P = 0.046), bladder function (P = 0.012), residual urine volume (P = 0.023) and SSEP (P = 0.002). However, no significant difference was noted in motor score (P = 0.193) or activities of daily living score (P = 0.161). Although the intervention group had a significant increase in complications (P < 0.001), no serious or permanent adverse events were reported. On subgroup analysis, low concentration of MSCs (<5 × 10⁷ cells) and initial AIS grade A presentation showed significantly better outcomes than their counterparts.

CONCLUSIONS

The authors' analysis establishes the efficacy and safety of MSC transplantation in terms of improvement in AIS grade, ASIA sensory score, bladder function and electrophysiological parameters like SSEP compared with controls, without major adverse events. However, further research is needed to standardize dose, timing, route and source of MSCs used for transplantation.

Exploring the contextual transition from spinal cord injury rehabilitation to the home environment: a qualitative study

Study design

Explorative qualitative study based on an interpretative phenomenological approach.

Objectives

This study explored the possibility of transferring knowledge and skills from a spinal cord injury (SCI) unit to the home environment; the individual and structural factors that potentially influenced this transfer; and its compatibility with a meaningful everyday life.

Setting

Hospital-based rehabilitation unit and community in Denmark.

Methods

Fourteen individuals with SCI were selected with maximum variation according to age, sex, marital status, and level of injury. In-depth, semi-structured interviews were conducted in the participants’ homes, 2–10 months after discharge from an SCI unit. Data analysis involved taking an interpretative phenomenological approach combined with a template analysis and applying the transfer of training theory to the discussion.

Results

Transitioning from the SCI unit to the home environment involved a multidimensional change of context in which most of the participants’ previous life roles had changed. This overarching theme had a decisive influence on: balancing loss and acceptance, facing external structural barriers, and the strength of social relationships when the knowledge and skills acquired at the unit were applied in a meaningful everyday life.

Conclusions

Transition from the SCI unit to the home environment is influenced by a multidimensional change of context that may restrict the use of acquired skills post-discharge, provide distant prospects for tertiary health promotion, and aggravate the experience of loss in people with SCI. Maintaining relationships is a strong mediator for transferring skills and re-establishing a meaningful everyday life.

A Scoping Review of Self-Management Interventions Following Spinal Cord Injury

Objective: To conduct a scoping review to identify what components of self-management are embedded in self-management interventions for spinal cord injury (SCI). Methods: In accordance with the approach and stages outlined by Arksey and O'Malley (2005), a comprehensive literature search was conducted using five databases. Study characteristics were extracted from included articles, and intervention descriptions were coded using Practical Reviews in Self-Management Support (PRISMS) (Pearce et al, 2016), Barlow et al (2002), and Lorig and Holman's (2003) taxonomy. Results: A total of 112 studies were included representing 102 unique self-management programs. The majority of the programs took an individual approach (52.0%) as opposed to a group (27.4%) or mixed approach (17.6%). While most of the programs covered general information, some provided specific symptom management. Peers were the most common tutor delivering the program material. The most common Barlow components included symptom management (n = 44; 43.1%), information about condition/treatment (n = 34; 33.3%), and coping (n = 33; 32.4%). The most common PRISMS components were information about condition and management (n = 85; 83.3%), training/rehearsal for psychological strategies (n = 52; 51.0%), and lifestyle advice and support (n = 52; 51.0%). The most common Lorig components were taking action (n = 62; 60.8%), resource utilization (n = 57; 55.9%), and self-tailoring (n = 55; 53.9%). Conclusion: Applying self-management concepts to complex conditions such as SCI is only in the earliest stages of development. Despite having studied the topic from a broad perspective, this review reflects an ongoing program of research that links to an initiative to continue refining and testing self-management interventions in SCI.

The Neuro-Orthopaedic Approach

Upper motor neuron disease or injury can lead to muscle spasticity or nonfunction throughout the body. Imbalance in muscle forces predisposes patients to development of functional deficiencies, contractures, pain, and poor hygiene. The approach to neuro-orthopaedic patients is by necessity multidisciplinary, because a variety of nonsurgical and surgical options are available. In evaluating each patient, surgeons must consider the extent and quality of any deformity, potential for improvement in function, the ability to alleviate pain, and potential for improvement in hygiene and cosmesis. Surgical techniques include tendon lengthenings, releases, transfers, osteotomies, and bony fusions.

The Efficacy and Safety of Mesenchymal Stem Cell Transplantation for Spinal Cord Injury Patients: A Meta-Analysis and Systematic Review

Spinal cord injury (SCI) is a devastating disease, with a high rate of disability. In this meta-analysis, we aimed to comprehensively assess the efficacy and safety of mesenchymal stem cells (MSCs) in treating clinical SCI patients. We systematically searched the PUBMED, EMBASE, Chinese Biomedical (CBM), Web of Science and Cochrane databases using the strategy of combination of free-text words and MeSH terms. The indicators of the American Spinal Injury Association (ASIA) impairment scale (AIS)-grading improvement rate and adverse effects were displayed with an overall relative risk (RR). For the continuous variables of the ASIA motor score, light-touch score, pinprick score, activities of daily living (ADL) score, and residual urine volume, we used odds ratio (OR) to analyze the data. Eleven studies comprising 499 patients meeting all inclusion and exclusion criteria were included. No serious heterogeneity or publication bias was observed across each study. The results showed that significant improvements of total AIS grade (RR: 3.70; P < 0.001), AIS grade A (RR: 3.57; P < 0.001), ASIA sensory score (OR: 8.63; P < 0.001) and reduction of residual urine volume (OR: -36.37; P = 0.03) were observed in experimental group compared with control group. However, no significant differences of motor score (OR: 1.37, P = 0.19) and ADL score (OR: 2.61, P = 0.27) were observed between experimental and control groups. In addition, there were no serious and permanent adverse effects after cell transplantation. Cell transplantation with MSCs is effective and safe in improving the sensory and bladder functions of SCI patients.

Is Fitbit Charge 2 a feasible instrument to monitor daily physical activity and handbike training in persons with spinal cord injury? A pilot study

Study design

It is a longitudinal pilot study.

Objectives

To investigate the feasibility of a low-cost and widely used fitness tracker with step count and heart rate data to monitor daily physical activity in wheelchair users with spinal cord injury (SCI).

Setting

Dutch community.

Methods

Six participants with SCI who were in training for a handbike event were recruited. They were asked to wear a Fitbit Charge 2^® 24 h a day for at least 2 weeks and were questioned about the utility and user-friendliness of this device.

Results

Five out of six participants managed to wear the device nonstop for 2 weeks, and continued to wear the device after this initial period. Most participants were enthusiastic about the direct feedback provided by the tracker and reported the data to be accurate. Data collected during more than 2 months of three participants and during 8 months on one of them showed the possibility of detecting training days and observing interpersonal and intrapersonal variation in daily physical activity level.

Conclusions

A commercially available, low-cost, self-monitoring multi-sensor wrist device or a fitness tracker like the Fitbit Charge 2^® can be a promising instrument to monitor daily activity levels among wheelchair users with SCI. The free commercial dashboard and log data clearly show trends of variations in physical activity and increases in heart rate, which are of value to both researchers and clinicians interested in identifying training schedules of wheelchair athletes.
