Physiotherapy interventions for the treatment of spasticity in people with spinal cord injury: a systematic review

Outcomes of Pressure Sore Surgery in Patients with Spinal Cord Injury and Spasticity

Background

Spasticity is a serious complication of spinal cord injury/disease (SCI/D) that affects 60%-80% of patients with this condition. The presence of spasticity can have a significant impact on the outcomes of reconstructive surgical interventions, such as those on pressure sores (PSs). Moreover, in the conservative treatment of PSs, spasticity may prevent maintaining adequate postures to avoid skin friction or traction. The aim of this study is to describe the PS reconstruction outcomes in a cohort of patients with SCI/D affected by spasticity.

Methods

In this retrospective study of patients with SCI/D consecutively admitted to Montecatone Rehabilitation Institute between October 2013 and March 2022, 54 PSs were treated in 46 people with spasticity.

Results

Postsurgery complications occurred in 26 of 54 treated PS, of which seven were major. Eleven patients experienced more than one complication. The overall incidence of postsurgical complications was 48.1%, and the incidence of major complications was 13%. Median length of hospital stay was 3.8 versus 1.8 months. Compared with other reports in the literature of PS reconstruction in patients with SCI/D, we found higher rates of overall, minor, and major complications.

Conclusions

Spasticity proved to be an important condition to consider, and its treatment requires specialized physicians. The collaboration between plastic surgeons and spasticity specialists is crucial to define the best treatment to reduce postoperative complications.

Efficacy of aquatic therapy in people with spinal cord injury: a systematic review and meta-analysis

STUDY DESIGN

Systematic review and meta-analysis. Spinal cord injury (SCI) is a pathological condition that provokes the loss of one or more body functions due to an injury to the spinal cord as a result of trauma or disease. Hydrotherapy plays a key role in the rehabilitation of neurological patients due to the properties of water environments.

OBJECTIVES

The goal of this study was to evaluate the efficacy of hydrotherapy in patients who suffer from SCIs.

METHODS

We searched 5 different databases: CINAHL, PubMed, Scopus, Web of Science, and PEDro for studies to include. Only randomized controlled trials (RCTs) published in English were considered. To evaluate the risk of bias, Jadad and PEDro scales were used.

RESULTS

Eleven Randomized Controlled Trials were included, and 3 articles remained to be analyzed. According to the evaluation through Cochrane Risk of Bias tool, one study had a high level of quality. The remaining 2 studies achieved a score indicative of a low level of quality. A total of 71 individuals with SCI were included in the studies; age and level of injury varied in each study. The outcome measures used in the studies were: Functional Independence Measure (FIM), Ashworth scale, CardioTouch 3000 s in sitting position and Quark CPET.

CONCLUSION

The aquatic environment provides a rehabilitation tool able to facilitate movement, physical and cardiovascular exercise, resistance training, and body relaxation.

Application of Vagus Nerve Stimulation in Spinal Cord Injury Rehabilitation

Spinal cord injury (SCI) is a prevalent devastating condition causing significant morbidity and mortality, especially in developing countries. The pathophysiology of SCI involves ischemia, neuroinflammation, cell death, and scar formation. Due to the lack of definitive therapy for SCI, interventions mainly focus on rehabilitation to reduce deterioration and improve the patient's quality of life. Currently, rehabilitative exercises and neuromodulation methods such as functional electrical stimulation, epidural electrical stimulation, and transcutaneous electrical nerve stimulation are being tested in patients with SCI. Other spinal stimulation techniques are being developed and tested in animal models. However, often these methods require complex surgical procedures and solely focus on motor function. Vagus nerve stimulation (VNS) is currently used in patients with epilepsy, depression, and migraine and is being investigated for its application in other disorders. In animal models of SCI, VNS significantly improved locomotor function by ameliorating inflammation and improving plasticity, suggesting its use in human subjects. SCI patients also suffer from nonmotor complications, including pain, gastrointestinal dysfunction, cardiovascular disorders, and chronic conditions such as obesity and diabetes. VNS has shown promising results in alleviating these conditions in non-SCI patients, which makes it a possible therapeutic option in SCI patients.

Effectiveness of physical therapy interventions on post-stroke spasticity: An umbrella review

BACKGROUND

Post-stroke spasticity is often one of the primary impairments addressed in rehabilitation. However, limited guidance exists on the effectiveness of physical therapy (PT) interventions for post-stroke spasticity.

OBJECTIVE

To evaluate the quality of evidence of PT interventions for post-stroke spasticity.

METHODS

Ovid (Medline), Cochrane Library, CINAHL, Scopus, PEDro, and PROSPERO were searched to identify reviews based on the following criteria: 1) published between 2012 and 2021, 2) participants older than 18 years old, 3) post-stroke spasticity, 4) PT interventions, 5) clinical or neurophysiological measures of spasticity as primary outcomes. Assessment of Multiple Systematic Reviews 2 and the Grades of Recommendations Assessment, Development, and Evaluation assessed methodological quality.

RESULTS

Eight articles were included in the analysis. No high-quality evidence was found. Moderate quality evidence exists for transcutaneous electrical nerve stimulation, neuromuscular electrical stimulation, resistance training, and lower extremity ergometer training with or without functional electrical stimulation. Low quality evidence exists for dynamic stretching, botulinum toxin with constraint-induced movement therapy, and static stretching using positional orthoses.

CONCLUSION

Findings suggest that PT should prioritize a combination of active strategies over passive interventions, but further studies are needed prioritizing analyses of the movement system in managing post-stroke spasticity in conjunction with medical therapies.

Evidence of treating spasticity before it develops: a systematic review of spasticity outcomes in acute spinal cord injury interventional trials

Introduction: Spasticity is a common consequence of spinal cord injury (SCI), estimated to affect up to 93% of people living with SCI in the community. Problematic spasticity affects around 35% people with SCI spasticity. The early period after injury is believed to be the most opportune time for neural plasticity after SCI. We hypothesize that clinical interventions in the early period could reduce the incidence of spasticity. To address this, we evaluated the spasticity outcomes of clinical trials with interventions early after SCI.Methods: We performed a systematic review of the literature between January 2000 and May 2021 to identify control trials, in humans and animals, that were performed early after SCI that included measures of spasticity in accordance with PRISMA guidelines.Results: Our search yielded 1,463 records of which we reviewed 852 abstracts and included 8 human trial peer-reviewed publications and 9 animal studies. The 9 animal trials largely supported the hypothesis that early intervention can reduce spasticity, including evidence from electrophysiological, behavioral, and histologic measures. Of the 8 human trials, only one study measured spasticity as a primary outcome with a sample size sufficient to test the hypothesis. In this study, neuromodulation of the spinal cord using electric stimulation of the common peroneal nerve reduced spasticity in the lower extremities compared to controls.Conclusion: Given the prevalence of problematic spasticity, there is surprisingly little research being performed in the early period of SCI that includes spasticity measures, and even fewer studies that directly address spasticity. More research on the potential for early interventions to mitigate spasticity is needed.

The Effect and Dose-Response of Functional Electrical Stimulation Cycling Training on Spasticity in Individuals With Spinal Cord Injury: A Systematic Review With Meta-Analysis

Background: To investigate the effect and dose-response of functional electrical stimulation cycling (FES-cycling) training on spasticity in the individuals with spinal cord injury (SCI). Method: Five electronic databases [PubMed, Scopus, Medline (Proquest), Embase, and Cochrane Central Register of Controlled Trials (CENTRAL)] were searched before September 2021. The human trials and studies of English language were only included. Two authors independently reviewed and extracted the searched studies. The primary outcome measure was spasticity assessed by Modified Ashworth Scale or Ashworth Scale for lower limbs. The secondary outcome measures were walking abilities, such as 6 Min Walk Test (6MWT), Timed Up and Go (TUG), and lower limbs muscle strength (LEMS). A subgroup analysis was performed to investigate the efficacious threshold number of training sessions. A meta-regression analysis was used to examine the linear relationship between the training sessions and the effect on spasticity. Results: A total of 764 studies were identified. After screening, 12 selected studies were used for the qualitative synthesis, in which eight of them were quantitatively analyzed. Eight studies included ninety-nine subjects in total with SCI (male: female = 83:16). The time since injury was from less than 4 weeks to 17 years. The age ranged from 20 to 67 years. American Spinal Injury Association (ASIA) impairment level of the number of participants was 59 for ASIA A, 11 for ASIA B, 18 for ASIA C, and 11 for ASIA D. There were 43 subjects with tetraplegia and 56 subjects with paraplegia. Spasticity decreased significantly (95% CI = - 1.538 to - 0.182, p = 0.013) in favor of FES-cycling training. The walking ability and LEMS also improved significantly in favor of FES-cycling training. The subgroup analysis showed that spasticity decreased significantly only in more than 20 training sessions (95% CI = - 1.749 to - 0.149, p = 0.020). The meta-regression analysis showed training sessions and spasticity were not significantly associated (coefficient = - 0.0025, SE = 0.0129, p = 0.849, R ² analog = 0.37). Conclusion: Functional electrical stimulation-cycling training can improve spasticity, walking ability, and the strength of the lower limbs in the individuals with SCI. The number of training sessions is not linearly related to the decrease of spasticity. Twenty sessions of FES-cycling training are required to obtain the efficacy to decrease spasticity.
