Physical modalities in the treatment of neurological dysfunction

Neurorehabilitation in Multiple Sclerosis-A Review of Present Approaches and Future Considerations

Multiple sclerosis is an increasingly prevalent disease, representing the leading cause of non-traumatic neurological disease in Europe and North America. The most common symptoms include gait deficits, balance and coordination impairments, fatigue, spasticity, dysphagia and an overactive bladder. Neurorehabilitation therapeutic approaches aim to alleviate symptoms and improve the quality of life through promoting positive immunological transformations and neuroplasticity. The purpose of this study is to evaluate the current treatments for the most debilitating symptoms in multiple sclerosis, identify areas for future improvement, and provide a reference guide for practitioners in the field. It analyzes the most cited procedures currently in use for the management of a number of symptoms affecting the majority of patients with multiple sclerosis, from different training routines to cognitive rehabilitation and therapies using physical agents, such as electrostimulation, hydrotherapy, cryotherapy and electromagnetic fields. Furthermore, it investigates the quality of evidence for the aforementioned therapies and the different tests applied in practice to assess their utility. Lastly, the study looks at potential future candidates for the treatment and evaluation of patients with multiple sclerosis and the supposed benefits they could bring in clinical settings.

Sensory interventions on motor function, activities of daily living, and spasticity of the upper limb in people with stroke: A randomized clinical trial

STUDY DESIGN

This is a single-blinded clinical trial study. Clinical Trial Number registry: IRCT201610223551N4.

INTRODUCTION

Stroke is the second cause of death around the world. Motor and sensory problems are common complications of the stroke. These defects in the upper limb cause reduced use of the affected limb and consequently a decrease in the quality of life.

PURPOSE OF THE STUDY

The purpose of this study was to examine the effect of exteroceptive and proprioceptive stimulations on motor function, spasticity of the upper limb, and activities of daily living in people who have had stroke.

METHODS

Sixty people with chronic stroke selected by convenience sampling. Before the intervention, Modified Ashworth Scale, Fugl-Meyer assessment of Motor Recovery after Stroke, and Barthel Index were measured and then the intervention phase was started. Exteroceptive and proprioceptive sensory stimulations were performed for 6 weeks. Independent t-test was used to compare groups.

RESULTS

The intervention group made improvement in motor function (P = .0001, Cohen's d = 2.14), activities of daily living of upper limb (P = .0001, Cohen's d = 1.32), and spasticity (P = .002, Cohen's d = -0.94).

DISCUSSION

Motor function and activities of daily living and spasticity of the upper limb can be improved through exteroceptive and proprioceptive stimulations. In this study, this type of intervention had the most impact on motor function compared with the rest.

CONCLUSION

Exteroceptive and proprioceptive stimulations in upper limb can be used in chronic phase of stroke. Improvement in motor function and activities of daily living and reducing spasticity are the results of these stimulations.

Physical therapy modalities in neurological disorders at developmental age - Assessment of the methodological value of research papers

BACKGROUND

Physical therapy modalities are often applied in treatment of neurological conditions in children and adolescents.

OBJECTIVE

Evaluation of the methodological quality of research focusing on the application of physical therapy modalities in children and adolescents with neurological conditions.

METHODS

Papers published between 2007 and 2018 were included in the review. 149 papers were analyzed and finally 26 studies investigating the use of physical therapy modalities in children and adolescents with neurological conditions were included in the review. Jadad scale (0-5) was used to assess the methodological value of the studies.

RESULTS

The mean Jadad score was 1.46 (researcher 1) and 1.38 (researcher 2). A score of 0 was awarded to nine (r1) and eight papers (r2). A score of 5 points was awarded to three (r1) and two papers (r2).

CONCLUSION

1. The evidence showing the effectiveness of the use of physical therapy modalities is mainly of low quality. 2. The Jadad scale is a valuable tool to assess the quality of research, although it does not always reflect the real value in the case children participate in studies. 3. The analyzed studies show that physical therapy modalities are effective in the treatment of children and adolescents with neurological disorders.

Effectiveness of Physiotherapy Interventions on Spasticity in People With Multiple Sclerosis: A Systematic Review and Meta-Analysis

OBJECTIVE

The aim of the study was to examine the effectiveness of physiotherapy (PT) interventions on spasticity in people with multiple sclerosis.

DESIGN

A systematic search was performed using PRISMA guidance. Studies evaluate the effect of PT interventions on spasticity were included. People with multiple sclerosis, spasticity, disability and PT interventions characteristics were extracted in included studies. Level of evidence was synthesized by the Grade of Recommendation, Assessment, Development and Evaluation approach. Meta-analyses were performed by calculating Hedges g at 95% confidence interval.

RESULTS

A total of 29 studies were included in the review, and 25 were included in the meta-analyses. The included PT interventions were exercise therapy, electrical stimulation, radial shock wave therapy, vibration, and standing. The review and meta-analyses showed different evidences of benefits and nonbenefits for PT interventions on some spasticity outcomes. The best quality evidences were for beneficial effects of exercise therapy especially robot gait training and outpatient exercise programs on self-perceived spasticity and muscle tone respectively. The review results were positive regarding the acute effects, follow-up measurements, safety, progressive MS, and nonambulatory people with multiple sclerosis. The included articles were heterogeneous and badly reported in PT interventions and people with multiple sclerosis characteristics.

CONCLUSIONS

Physiotherapy interventions can be a safe and beneficial option for spasticity in people with multiple sclerosis. No firm conclusion can be drawn on overall spasticity. Further researches in different spasticity aspects are needed.

Respiratory muscles stretching acutely increases expansion in hemiparetic chest wall

Individuals post-stroke may present restrictive ventilatory pattern generated from changes in the functionality of respiratory system due to muscle spasticity and contractures. Objective was to assess the acute effects after respiratory muscle stretching on the ventilatory pattern and volume distribution of the chest wall in stroke subjects. Ten volunteers with right hemiparesis after stroke and a mean age of 60 ± 5.7 years were randomised into the following interventions: respiratory muscle stretching and at rest (control). The ventilatory pattern and chest wall volume distribution were evaluated through optoelectronic plethysmography before and immediately after each intervention. Respiratory muscle stretching promoted a significant acute increase of 120 mL in tidal volume, with an increase in minute ventilation, mean inspiratory flow and mean expiratory flow compared with the control group. Pulmonary ribcage increased 50 mL after stretching, with 30 mL of contribution to the right pulmonary rib cage (hemiparetic side) in comparison to the control group. Respiratory muscle stretching in patients with right hemiparesis post-stroke demonstrated that acute effects improve the expansion of the respiratory system during tidal breathing.

Physical therapy is targeted and adjusted over time for the rehabilitation of locomotor function in acute spinal cord injury interventions in physical and sports therapy

STUDY DESIGN

Prospective observational multicenter study.

OBJECTIVES

Investigation of content, duration and adjustment of physical therapy for the rehabilitation of ambulation in acute spinal cord injury (SCI).

SETTING

European Multicenter Study of SCI (EMSCI).

METHODS

Physical therapy interventions during acute in-patient rehabilitation of eighty incomplete SCI patients (AIS B, C, D all lesion levels) were recorded using the SCI - Intervention Classification System. Mobility was documented using the Spinal Cord Independence Measurement (SCIM III), demographics and clinical data were retrieved from the EMSCI database.

RESULTS

Overall recovery of locomotor function was categorized into three outcome groups (G1-G3). Of 76 initial wheelchair-using patients, 53.9% remained wheelchair user (G1), 25% regained moderate (G2) and 21.1% good walking (G3) capability. Strength training was the most frequently applied intervention of body function/-structure across all outcome groups (about 30% of all interventions), while interventions focusing on muscle tone and respiration were predominantly applied in wheelchair-dependent patients. Activity-focused interventions of transfer, transition, sitting were trained most intensively in outcome group G1, while walking and swimming were increasingly trained in patients with moderate and good walking outcomes. Physical therapy interventions of assistive and active trainings as well as corresponding training environments changed with the recovery of locomotor function.

CONCLUSIONS

Physical therapy of locomotor function is targeted to individual patients' conditions and becomes adjusted to the progress of ambulation. Although the involved clinical sites were not following explicitly standardized rehabilitation programs, common patterns can be discerned which may form the basis of prospective standardized programs.

Pediatric feeding and swallowing rehabilitation: An overview

Children with neurological disabilities frequently have problems with feeding and swallowing. Such problems have a significant impact on the health and well-being of these children and their families. The primary aims in the rehabilitation of pediatric feeding and swallowing disorders are focused on supporting growth, nutrition and hydration, the development of feeding activities, and ensuring safe swallowing with the aim of preventing choking and aspiration pneumonia. Pediatric feeding and swallowing disorders can be divided into four groups: transient, developmental, chronic or progressive.This article provides an overview of the available literature about the rehabilitation of feeding and swallowing disorders in infants and children. Principles of motor control, motor learning and neuroplasticity are discussed for the four groups of children with feeding and swallowing disorders.

Facilitation handlings induce increase in electromyographic activity of muscles involved in head control of cerebral palsy children

This study aimed to investigate the electromyographic (EMG) activation of the main cervical muscles involved in the head control during two postures widely used for the facilitation of head control in children with Cerebral Palsy (CP). A crossover trial involving 31 children with clinical diagnosis of CP and spastic quadriplegia was conducted. Electromyography was used to measure muscular activity in randomized postures. Three positions were at rest: (a) lateral decubitus, (b) ventral decubitus on the floor and (c) ventral decubitus on the wedge. Handlings for facilitating the head control were performed using the hip joint as key point of control in two postures: (a) lateral decubitus and (b) ventral decubitus on wedge. All children underwent standardized handlings, performed by the same researcher with experience in the neurodevelopmental treatment. EMG signal was recorded from muscles involved in the head control (paraspinal and sternocleidomastoid muscles) in sagittal, frontal and transverse planes, at the fourth cervical vertebra (C4), tenth thoracic vertebra (T10) and sternocleidomastoid muscle (SCM) levels. The results showed a significant increase in muscle activation when handling was performed in the lateral decubitus at C4 (P<0.001), T10 (P<0.001) and SCM (P=0.02) levels. A significant higher muscle activation was observed when handling was performed in lateral decubitus when compared to ventral decubitus at C4 level (P<0.001). Handling in ventral decubitus also induced an increase in EMG activation at T10 (P=0.018) and SCM (P=0.004) levels but not at C4 level (P=0.38). In conclusion, handlings performed in both positions may induce the facilitation of head control, as evaluated by the activity of cervical and upper trunk muscles. Handling performed in lateral decubitus may induce a slightly better facilitation of head control. These findings contribute to evidence-based physiotherapy practice for the rehabilitation of severely spastic quadriplegic CP children.

Molecular mechanisms underlying the effects of acupuncture on neuropathic pain

Acupuncture has been used to treat neuropathic pain for a long time, but its mechanisms of action remain unknown. In this study, we observed the effects of electroacupuncture and manual acu-puncture on neuropathic pain and on ephrin-B/EphB signaling in rats models of chronic constriction injury-induced neuropathic pain. The results showed that manual acupuncture and elec-puncture significantly reduced mechanical hypersensitivity following chronic constriction injury, es-pecially electroacupuncture treatment. Real-time PCR results revealed that ephrin-B1/B3 and EphB1/B2 mRNA expression levels were significantly increased in the spinal dorsal horns of chronic constriction injury rats. Electroacupuncture and manual acupuncture suppressed the high sion of ephrin-B1 mRNA, and elevated EphB3/B4 mRNA expression. Electroacupuncture signifi-cantly enhanced the mRNA expression of ephrin-B3 and EphB3/B6 in the dorsal horns of neuro-pathic pain rats. Western blot results revealed that electroacupuncture in particular, and manual acupuncture, significantly up-regulated ephrin-B3 protein levels in rat spinal dorsal horns. The re-sults of this study suggest that acupuncture could activate ephrin-B/EphB signaling in neuropathic pain rats and improve neurological function.
