“…De este modo, las personas con una LM dorsal o cervical manifiestan una reducción de la capacidad de ventilación pulmonar, con una reducción de todos los volúmenes y capacidades pulmonares, especialmente el FEV-1 (volumen espiratorio forzado) y la FVC (capacidad vital forzada), reduciéndose progresivamente tras producirse la lesión y generando predisposición a sufrir infecciones del tracto respiratorio (Martínez y López, 2014;Ovechkin et al, 2010). Cuando la LM se localiza por encima de T1, pero por debajo de C4, los músculos escalenos, pectorales, trapecio y esternocleidomastoideo, comportan un papel auxiliar esencial, junto al diafragma (Bach, 2006), para compensar la parálisis de los músculos intercostales y abdominales (Costoso et al, 2002).…”

ResumenUna de cada 2000 personas en Europa tiene lesión medular (LM), es normalmente más sedentaria que el resto de la población y encuentra diferentes problemas para practicar ejercicio físico (EF), destacando la escasa formación específica de los profesionales del deporte. Con el objetivo de aportar información sobre la LM y su interacción con la práctica deportiva, se realizó una revisión de literatura científica que analiza sus alteraciones músculoesqueléticas, cardiovasculares, respiratorias, de termorregulación, genitourinarias e intestinales, las úlceras por presión, la disreflexia autonómica y los aspectos nutricionales, generando recomendaciones prácticas. Como conclusión, la práctica habitual de EF reduce la incidencia de enfermedades respiratorias y cardiovasculares, mejorando la condición física, la autonomía personal y la salud de las personas con LM, así como su calidad y esperanza de vida, pero es imprescindible conocer sus características particulares tanto para optimizar su rendimiento deportivo como para evitar graves complicaciones médicas. Palabras claveParaplejia, tetraplejia, actividad física, deporte. AbstractOne in 2,000 people in Europe has spinal cord injury (SCI). These persons are usually more sedentary than the rest of the population and encounters different problems to practice physical exercise (PE), in part because of the limited specific training of sports professionals. In order to provide specific information about SCI and its interaction with the practice of sports, a review of scientific literature was carried out. Different kinds of disorders as musculoskeletal, cardiovascular, respiratory, thermoregulation, genitourinary and intestinal, pressure ulcers, autonomic dysreflexia and nutritional aspects were analyzed in order to make useful recommendations. In conclusion, the practice of PE reduces the incidence of respiratory and cardiovascular diseases and improves physical fitness, personal autonomy, health, quality of life and life expectancy of people with SCI. However it is essential to be familiar with the persons particular characteristics in order to optimize their athletic performance and to prevent serious medical complications.

“…However, assessments using these tools fail to provide information about underlying neural drive to the respiratory motor system (A. Ovechkin et al, 2010;Terson de Paleville & Lorenz, 2015). Unfortunately, there is profound lack of knowledge about development of respiratory motor control in neurologically intact children.…”

“…Therefore, motor dysfunction of trunk muscles after SCI also will affect respiratory functions, with over activation of available accessory muscles of breathing to compensate for paralysis of primary respiratory muscles (A. Ovechkin, Vitaz, de Paleville, Aslan, & McKay, 2010;Terson de Paleville & Lorenz, 2015). The higher cervical injury leads to paralysis of most of the intercostal, rectus abdominals, and external oblique muscles.…”

Trunk and respiratory motor control in typically developing children and its implications in children with chronic spinal cord injury.

Singh, Goutam, "Trunk and respiratory motor control in typically developing children and its implications in children with chronic spinal cord injury." (2017 Independent sitting is a major milestone and is also a prerequisite for optimal performance of activities of daily living (ADLs). Development of sitting posture control is a dynamic process involving control of degrees of freedom of head and trunk. Traditionally, trunk has been modeled as a single unit (segment).However, recent studies have suggested that it is made up multiple spinal units, controlled by a combination of trunk muscles. During typical development, posture control of trunk is different for different trunk segments. This motor development of trunk control is a complex process due to constant interaction between the nervous system and environment. Any interruption in the normal processes would further complicate it, affecting the typical development of the child.Poor trunk control and respiratory complications are characteristic features among children, adolescents, and adults with neuromuscular disorders.vi Pediatric spinal cord injuries (SCIs) also pose a unique challenge compared to SCI in adults because of the continuous physical and cognitive development.Children with SCI exhibit deficits in trunk motor control, which impair their ability to sit or ambulate. These motor deficits can lead to compensatory changes in other segments of the body, which cause further deviations from typical postures.Trunk muscles have the dual function of supporting both, breathing and trunk posture. Therefore, in children with SCI, impairment of posture control will also affect respiratory functions. Depending on level and severity of injury, can potentially lead to severe respiratory insufficiency. Symptoms of respiratory insufficiency are highly correlated with the level and severity of spinal lesions.Injury at higher cervical and thoracic cord levels causes paresis and paralysis of most of the respiratory muscles, which increase the workload of breathing. As a result, respiratory complications are the leading cause of death among children with SCI. Therefore, impairment of posture control following SCI also affects respiratory functions.Lack of appropriate tools to evaluate trunk motor control following SCI restricts the ability to understand its development and therefore it is a challenge to design treatments and strategies to slow down or prevent the progress of longterm effects of SCI in children. In this dissertation, we studied the postural control using a Segmental Assessment Trunk Control (SATCo) test and respiratory motor control using Respiratory Motor Control Assessment (RMCA) protocol in typically developing (TD) children and compared their results to age-matched children with SCI.vii Chapter I describes the background information about the trunk and respiratory motor control and how the injury to spinal cord impacts these motor functions. Chapter II illustrates the specific aims and hypothesis of this dissertation. Methods and protocols used to ...

Introduction Individuals with spinal cord injury (SCI) frequently have an ineffective cough ability due to dysfunctions in expiratory muscles. In such cases, several articles have reported the occurrence of residual muscular activity in muscles that are accessory to coughing. The knowledge about this activity may be useful for building cough assistance devices. The goal of this review is to investigate and to describe the electromyographic signals generated during voluntary coughing in healthy people and in patients with SCI. Methods Two researchers performed, blindly and independently, a systematic review of the following databases: PubMed, PEDro, LILACS, and Science Direct. We conducted the searches using descriptors in English, Portuguese, and Spanish, with no limitations regarding the publication year. The review included articles describing experiments performed in humans and with the use of electromyographic signals in the analysis of voluntary coughing. Results Among the 156 initially found articles, only nine had results that described the study of electromyographic signals associated with voluntary coughing. The results showed evidence that, during voluntary coughing, electromyographic signals are generated both in expiratory and accessory muscles in healthy subjects. In individuals with SCI below the 5th cervical level (C5), the electromyographic signal appeared only in the clavicular portion of the pectoralis major, especially in the explosive cough phase. Conclusion Our evaluation of the current literature shows that, according to the analysed studies, the electromyographic signals are more pre‐eminent in the expiratory phase of the pectoralis major, during voluntary cough of individuals with SCI (C5–T12).
