Special Considerations and Assessment in Patients with Multiple Sclerosis

Development of an integrated conceptual model of multiple sclerosis spasticity

PURPOSE

Spasticity is common in multiple sclerosis (MS), often leading to functional limitations and disability. We developed a conceptual model of spasticity in MS integrating expert opinion, recent literature, and experiences of clinicians and people with MS spasticity.

METHODS

A conceptual model was developed based on a targeted literature review of articles published between 2014 and 2019, followed by input from clinicians, then input from participants with MS spasticity. Multidisciplinary experts on spasticity provided guidance at each step.

RESULTS

Key concepts of the integrated spasticity conceptual model included: moderators; triggers; modifiers; treatment; objective manifestations; subjective experience; physical, functional, social, and emotional/psychological impacts; and long-term consequences. Participants with MS spasticity most frequently endorsed spasms, tightness, and pain as descriptors of spasticity. Some participants with MS spasticity had difficulty distinguishing spasticity from other MS symptoms (e.g. muscle weakness). Some triggers, emotional/psychological impacts, and long-term consequences of spasticity reported by participants with MS spasticity were not previously identified in the published literature.

CONCLUSIONS

This conceptual model of spasticity, integrating published literature with the experience of clinicians, people with MS spasticity, and experts, demonstrates the complex, multidimensional nature of MS spasticity. This model may be used to improve clinician-patient dialogue, research, and patient care.

Dry needling for treating spasticity in multiple sclerosis

[Purpose] The aim of the study is to evaluate the efficacy of dry needling (DN) in the treatment of spasticity in patients with multiple sclerosis (MS). [Participants and Methods] Twelve participants (3 males and 9 females) with MS, with no evidence of a relapse in the last four weeks and with an EDSS (Expanded Disability Status Scale) greater than 2.5 points (related with pyramidal score) were recruited. DN was performed in lower limbs for 12 consecutive sessions and evaluated with: PSFS (Penn Spasm Frequency Scale), VAS (visual analogical scale) of spasticity, EDSS (Pyramidal item), Time up and go (TUG), 25 foot, 9hold peg test (9HPT) and the improvement or not in the quality of life (MSQol54) was verified before and after treatment. A follow up visit was carried out to assess improvement. [Results] All patients improved in: VAS scale, EDSS score, quality of life, 9HPT, 25 foot test and TUG and 90% of them showed a decrease in the number of spasms/hour (PSFS). [Conclusion] Dry needling produces positive changes in spasticity in patients with MS and their quality of life, as well as walking capacity and manual dexterity. Therefore, DN should be considered in the treatment of spasticity in patients with MS.

Viral infections and their relationship to neurological disorders

The chronic dysfunction of neuronal cells, both central and peripheral, a characteristic of neurological disorders, may be caused by irreversible damage and cell death. In 2016, more than 276 million cases of neurological disorders were reported worldwide. Moreover, neurological disorders are the second leading cause of death. Generally, the etiology of neurological diseases is not fully understood. Recent studies have related the onset of neurological disorders to viral infections, which may cause neurological symptoms or lead to immune responses that trigger these pathological signs. Currently, this relationship is mostly based on epidemiological data on infections and seroprevalence of patients who present with neurological disorders. The number of studies aiming to elucidate the mechanism of action by which viral infections may directly or indirectly contribute to the development of neurological disorders has been increasing over the years but these studies are still scarce. Comprehending the pathogenesis of these diseases and exploring novel theories may favor the development of new strategies for diagnosis and therapy in the future. Therefore, the objective of the present study was to review the main pieces of evidence for the relationship between viral infection and neurological disorders such as Alzheimer's disease, Parkinson's disease, Guillain-Barré syndrome, multiple sclerosis, and epilepsy. Viruses belonging to the families Herpesviridae, Orthomyxoviridae, Flaviviridae, and Retroviridae have been reported to be involved in one or more of these conditions. Also, neurological symptoms and the future impact of infection with SARS-CoV-2, a member of the family Coronaviridae that is responsible for the COVID-19 pandemic that started in late 2019, are reported and discussed.

MS Spasticity: Take Control (STC) for ambulatory adults: protocol for a randomized controlled trial

Background

Spasticity affects 60–80% of people with multiple sclerosis (MS), impacting activity, participation and quality of life. We developed the group delivered spasticity self-management program, “MS Spasticity: Take Control” (STC), with DVDs for education and lower extremity stretching. STC is based on an international guideline and recommendations from systematic reviews and emphasizes the importance of stretching with specific stretching exercises. Our pilot trial (n = 38) compared STC followed by one month of home stretching practice to unguided use of the National MS Society (NMSS) brochure titled “Stretching for People with MS: An Illustrated Manual,” also followed by one month of home stretching practice. In this pilot trial, STC showed promising effects on the impact of spasticity (MS Spasticity Scale-88) and other self-report and physical performance measures. We will now carry out a fully-powered trial to evaluate the effect of STC compared to a comparably delivered control program on the impact and severity of spasticity in people with MS and self-reported lower extremity spasticity.

Methods

Two hundred-twenty ambulatory adults with MS self-reported spasticity interfering with daily activities will be randomized 1:1 to STC or control, using the same NMSS brochure used in the pilot study, with both programs delivered in groups with trained facilitators. Outcomes are the impact of spasticity with the MS Spasticity Scale-88, the severity of spasticity with the Numeric Rating Scale for Spasticity, other self-report questionnaires, and physical performance walking measures at baseline and one and 6 months after the interventions.

Discussion

Stretching is the cornerstone of spasticity management. Stretching takes time and energy every day. Unfortunately, beyond the logical expectation that regular stretching should help prevent muscle shortening and contractures in the presence of spasticity, there is very little data on the effects of stretching on spasticity in people with MS or any other condition. Our pilot trial of STC suggested that education and stretching help reduce the impact of spasticity. To definitively determine if this education and instructional program with daily stretching practice is effective, a fully powered trial with a comparable control intervention and facilitators who did not create STC is needed. Here we report the protocol for this trial.

The co-occurrence of multiple sclerosis and Evans syndrome: A case report

BACKGROUND

Evans syndrome is an uncommon autoimmune disorder manifested by fatigue, jaundice, pallor, purpura and petechiae. The main characteristics of this rare disease are simultaneous or sequential existence of positive anti-globulin test, immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA). Evans syndrome as an autoimmune disorder can be associated with other diseases. The concomitancy of Evans syndrome and multiple sclerosis (MS) has not been reported so far. In this case study, a -21-year old male with concomitant Evans syndrome and MS has been reported.

CASE PRESENTATION

A 21-year-old male of Iranian origin and known case of Evans syndrome, was referred to our hospital for better evaluation. Evans syndrome was presented with acute jaundice, purpura, petechiae, and easy bruising when he was 9.He was under treatment of corticosteroid and cytotoxic agents, and presented with left lower extremity paresis for 5 months before admission to our hospital. According to neuroimaging and pathologic results, multiple sclerosis (MS) was diagnosed. Hence, we decided to treat the patient with rituximab. The patient has been stable without any further exacerbation or increase in disability progression after 2 years from diagnosis.

CONCLUSION

Evans syndrome can be associated with other autoimmune disorders. For our case, we have reported this association with MS.
