Spinal Cord Series and Cases最新文献

Introduction

Patients with spinal cord injury (SCI) and incomplete paralysis may experience muscle immobilization due to functional impairment of agonist and antagonist muscles. This can induce spasticity and pain, with the risk of contracture increasing as the period of immobilization increases. This could be aggravated by pain, which interferes with rehabilitation. There is no established treatment for pain and joint contractures caused by acute SCI. Botulinum therapy plays a role in relieving muscle tension. Here, we report a case of acute SCI in which botulinum therapy was administered.

Case presentation

The patient experienced a C5-cervical SCI due to a road traffic accident, with marked paralysis in the upper and lower limbs below the C5 level. The patient had persistent elbow flexion since the SCI and complained of excruciating pain, making adequate rehabilitation difficult. Botulinum toxin was administered to the biceps and brachialis muscles 15 days after the SCI. After administration, the patient experienced a reduction in pain with relaxation of the elbow flexor muscles, and rehabilitation treatment was resumed. This patient’s contracture did not worsen, his pain decreased, and he was able to initiate self-feeding training.

Discussion

In this case, occupational and physical therapy was administered with botulinum therapy. Together, they successfully reduced pain. Botulinum therapy provides analgesia and muscle relaxation and may lead to functional recovery, and we believe that treatment can be considered even in the acute phase.

Study design

Development and psychometrics study

Objective

To evaluate the reliability and validity of a new version of Appraisals of Post-Traumatic Spinal Cord Injury Health Scale (APTSCIHS) in the Persian language for persons with spinal cord injury (SCI).

Setting

The persons were selected from National Spinal Cord Injury Registry of Iran (NSCIR-IR) and Brain and Spinal Cord Injury Research center (BASIR).

Method

This was a mixed sequential exploratory study that performed in two phases. In the qualitative phase, a systematic scoping review and 12 interviews with the participants were done. Finally, items were generated. In the quantitative phase, face, content, construct and convergent validity were assessed to evaluate validity. To evaluate construct validity, a cross-sectional study was conducted on 305 persons with TSCI along with internal consistency and stability assessments. All quantitative data analyses were conducted using SPSS 22 software.

Results

The content validity and reliability were indicated by Scale’s Content Validity Ratio (S-CVR) = 0.73 and Scale’s Content Validity Index (S-CVI) = 0.86, Cronbach’s α = 0.9 and the Test re-test reliability using intra-class correlations were (ICC) = 0.97 to 0.98. Exploratory factor analysis determined eight factors which showed more than 52% of the variance. APTSCIHS had a significant and strong correlation with Appraisals of DisAbility Primary and Secondary Scale (ADAPSS) (r = 0.475, P < 0.001).

Conclusion

Results showed the 36 items APTSCIHS tool had an acceptable validity and reliability in Iran, and it can help health care providers or even administrators improve the quality of the rehabilitation services and quality of life.

Study design

Qualitative exploratory study.

Objectives

To understand the lived experiences of individuals with spinal cord injuries or disorders (SCI/D) who use wheelchairs during air travel in the United States (US), with a focus on the challenges and barriers to accessing this form of transportation.

Setting

Wheelchair users with SCI/D living in the community in the US.

Methods

Semi-structured interviews were used to collect data from six wheelchair users with SCI/D. Data were analyzed using a six-step thematic analysis.

Results

Experiences of wheelchair users during air travel clustered into three themes; experiences interacting with the airport, experiences interacting with the airplane, and experiences across all stages of air travel. Barriers to airport accessibility were minimal. Physical barriers to airplane accessibility and damage to wheelchairs occurred when interacting with the airplane and airline staff. Undertrained staff and a shift in responsibility to the passenger with a disability impacted all stages of the experience.

Conclusion

Wheelchair users with SCI/D encounter challenges that can result in unsafe and inaccessible air travel within the US. Adverse consequences of air travel often impact the individual’s independence and quality of life during and after the flight. Participants provided recommendations to improve the air travel experience for wheelchair users, including the ability to remain in one’s wheelchair while onboard the airplane.

Introduction

Although multimodal intraoperative neuromonitoring (IONM), which has high sensitivity and specificity, is typically performed during spinal deformity surgery, neurological status may deteriorate with delay after surgical maneuvers. Here, we report a rare case of delayed postoperative neurological deficit (DPND) that was not detected by IONM during posterior spinal fusion (PSF) for congenital scoliosis.

Case presentation

A 14-year-old male presented with congenital scoliosis associated with T3 and T10 hemivertebrae. Preoperative Cobb angle of proximal thoracic (PT) and main thoracic (MT) curves were 50° and 41°, respectively. PSF (T1-L1) without hemivertebrectomy was performed, and the curves were corrected to 31° and 21° in the PT and MT curves, respectively, without any abnormal findings in IONM, blood pressure, or hemoglobin level. However, postoperative neurological examination revealed complete loss of motor function. A revision surgery, release of the curve correction by removing the rods, was immediately performed and muscle strength completely recovered on the first postoperative day. Five days postoperatively, PSF was achieved with less curve correction (36° in the PT curve and 26° in the MT curve), without postoperative neurological deficits.

Discussion

Possible mechanisms of DPND in our patient are spinal cord ischemia due to spinal cord traction caused by scoliosis correction and spinal cord kinking by the pedicle at the concave side. Understanding the possible mechanisms of intra- and postoperative neural injury is essential for appropriate intervention in each situation. Additionally, IONM should be continued to at least skin closure to detect DPND observed in our patient.

Introduction

Powered robotic exoskeleton (PRE) physiotherapy programmes are a relatively novel frontier which allow patients with reduced mobility to engage in supported walking. Research is ongoing regarding their utility, risks, and benefits. This article describes the case of two fractures occurring in one patient using a PRE.

Case

We report the case of a 54 year old man who sustained bilateral tibial fractures while using a PRE, on a background of T10 AIS A SCI. The initial session was discontinued due to acute severe bilateral knee swelling after approximately 15 min. The patient attended their local hospital the following day, where radiographs demonstrated bilateral proximal tibial fractures. The patient was treated with manipulation under anaesthetic and long-leg casting for five weeks, at which point he was stepped down to hinged knee braces which were weaned gradually while he remained non-weight bearing for 12 weeks. The patient was investigated with DEXA scan and was diagnosed with osteoporosis. He was liaised with rheumatology services and bone protection was initiated. Fracture healing was achieved and weight-bearing precautions were discontinued, however this period of immobilisation led to significant spasticity. The patient was discharged from orthopaedic services, with ongoing rehabilitation and physiotherapy follow-up.

Conclusion

PRE assisted physiotherapy programmes are a promising concept in terms of rehabilitation and independence, however they are not without risk and it is important that both providers and patients are aware of this. Furthermore, SCI patients are at increased risk for osteoporosis and should be monitored and considered for bone protection.

Study design

Scoping systematic review.

Objectives

To summarize the available experimental clinical and animal studies for the identification of all CSF and serum-derived biochemical markers in human and rat SCI models.

Setting

Tehran, Iran.

Methods

In this scoping article, we systematically reviewed the electronic databases of PubMed, Scopus, WOS, and CENTRAL to retrieve current literature assessing the levels of different biomarkers in human and rat SCI models.

Results

A total of 19,589 articles were retrieved and 6897 duplicated titles were removed. The remaining 12,692 studies were screened by their title/abstract and 12,636 were removed. The remaining 56 were considered for full-text assessment, and 11 papers did not meet the criteria, and finally, 45 studies were included. 26 studies were human observational studies comprising 1630 patients, and 19 articles studied SCI models in rats, including 832 rats. Upon reviewing the literature, we encountered a remarkable heterogeneity in terms of selected biomarkers, timing, and method of measurement, studied models, extent, and mechanism of injury as well as outcome assessment measures.

Conclusions

The specific expression and distribution patterns of biomarkers in relation to spinal cord injury (SCI) phases, and their varied concentrations over time, suggest that cerebrospinal fluid (CSF) and blood biomarkers are effective measures for assessing the severity of SCI.

Study design

Feasibility study.

Objective

To determine the feasibility of conducting a large trial designed to determine whether the ROBERT^® can be used to increase the strength of the hip flexor muscles after spinal cord injury (SCI). The ROBERT^® is a robotic device that provides assisted active movement while supporting the weight of the leg. Focus was on recruitment capability, suitability, and acceptability of the intervention and outcome measure.

Setting

Specialised SCI centre in Denmark.

Methods

All first-time admitted patients were screened to assess participant recruitment capability. Four people with SCI < 3 months tested a protocol consisting of 60 repetitions of hip flexion in supine conducted with the assistance of the ROBERT^® three times a week for 4 weeks. Feasibility was assessed based on adherence to the protocol and completion rate and from the participants’ perspectives. Maximal voluntary contraction (MVC) was accessed at baseline and four weeks.

Results

The recruitment rate was 8% (7 months). The four participants completed 44 out of 48 sessions (92%). No adverse events occurred. One physiotherapist was required to set-up and supervise each session. The active exercise time varied from 7.5 to 17 min. The participants found the ROBERT^® a good supplement to their usual rehabilitation. We were able to measure MVC in even very weak hip flexor muscles with a dynamometer MicroFET2 fixed to a frame.

Conclusion

The ROBERT^® was feasible and acceptable. The participants perceived it as a supplement, not a replacement to usual physiotherapy. However, recruitment to the study was slow.

Trial registration

ClinicalTrials.gov NCT05558254. Registered 28th September 2022.

Study design

Cross-Sectional Study.

Objectives

To investigate the changes in the characteristics of cervical spinal cord injuries (CSCI) before and after the coronavirus disease 2019 (COVID-19) pandemic among patients transported to our hospital in Japan.

Setting

Hospital with an emergency center in Chiba, Japan.

Methods

Patients eligible for the study were those transported within 24 h of injury and diagnosed with cervical spinal cord injury between January 2018 and December 2021 at our hospital. Medical records were retrospectively examined to investigate the number and characteristics of patients with CSCI. The clinical variables of patients with CSCI were compared according to the time of admission as related to the COVID-19 pandemic: 2018-19 (before) or 2020-21 (after).

Results

The total number of patients with CSCI from 2018 to 2021 was 108, with 57 before the COVID-19 pandemic and 51 after the COVID-19 pandemic. The number of severe cases with an injury severity score (ISS) of >16 decreased after COVID-19 (p < 0.05). Falls on level surfaces were the most common cause of injury both before and after COVID-19. Although the ranking of traffic accidents decreased after COVID-19, among those, the number of bicycle injuries tended to increase.

Conclusions

The number of serious cases with an ISS > 16 decreased, presumably because of the decline in high-energy trauma due to the background decrease in the number of traffic accidents.

Introduction

Pneumorrachis is presence of air in the epidural space. It could be the result of trauma, barotrauma, iatrogenic or spontaneous. The pneumorrachis per se is an underdiagnosed entity as most of the patients are asymptomatic or have subclinical symptoms. The spontaneous occurrence of pneumorrachis has been reported in literature but giant spontaneous occurrence causing cauda equina syndrome has not been reported so far.

Case presentation

We report a case of 56-year-old male patient who came to our OPD on wheelchair with complains of difficulty in walking for 6 months with dribbling of urine for 2 months with on and off back pain. His perianal sensation was reduced with absent voluntary anal contraction. Imaging revealed giant air pockets in the spinal canal of L5-S1 extending upto L4-L5. It was managed surgically wherein laminectomy without fusion was done. The patient responded well to the treatment.

Discussion

There are many causes of pneumorrachis described in literature. Most of the cases of pneumorrachis are asymptomatic and incidentally diagnosed. With the improvement in radio-diagnostic modalities, the diagnosis of pneumorrachis can be easily established. When symptomatic, they can be managed conservatively. Those presenting with neurological deficit may require surgical intervention or other invasive intervention.

Introduction

Historically, bladder washouts were used to instil therapeutic reagents directly into the bladder. This practice has expanded to include instillation of solutions that deal with catheter issues such as encrustation or formation of bio-film. They appear to provide a promising strategy for people with long term catheters. These products are readily available to purchase, but there is concern that people are using these solutions without a complete understanding of the purpose for the rinse and without clinical guidance to monitor response to treatment.

Case presentation

These case studies include three people living with spinal cord injury (SCI) who developed severe autonomic dysreflexia (AD) when a catheter rinse was carried out using a particular solution. Each of the cases developed immediate and, in some cases, intractable AD requiring further intervention to resolve symptoms.

Discussion

Catheter-associated urinary tract infection is a significant cause of morbidity and mortality in people living with SCI. Long-term catheters provide a vector for opportunistic micro-organisms to form bio-film and create an environment that promotes formation of struvite calculi, thus increasing the risk of chronic catheter blockage and urinary tract infection. Whilst these solutions are used to reduce these risks, they also pose additional risks to people susceptible to AD. These cases highlight the need for judicious patient selection and clinical oversight and management of adverse events when using catheter rinse solutions in certain people living with SCI. This is supported by a decision-making algorithm and a response to AD algorithm.
