Introduction

Spinal cord injury (SCI) has a limiting effect because it causes several functional irregularities in the affected individual, such as locomotive, sensitive, sexual problems, urinary and intestinal disorders [1]. Its etiology may result from traumatic occurrences, such as traffic accidents, gunshot wounds, diving in shallow waters; and non-traumatic resulting from infectious processes, tumors and congenital deficiencies [2]. The functional recovery capacity of patients with SCI is based on factors such as age, degree of injury, as well as the therapeutic approach applied during the acute phase [3].

Over the years, researchers have observed that due to the injuries generated by SCI, the individual has difficulty accepting this functional limit, affecting family members and professionals involved, such as caregivers and the multidisciplinary team [3]. The role of physiotherapy aims to provide quality of life and develop self-esteem for these patients through actions of functional independence and social inclusion, therefore reducing situations of instability related to mental and psychological health [3,4]. It is important for patients to have the appropriate stimulus, in order to allow the effectiveness of physical therapy treatment and increase adherence rates. For this, technological resources have been developed for applicability in rehabilitation, such as games and virtual reality [2].

In light of this context, this study aimed to identify, through a systematic literature review, the role of Neurofunctional Physiotherapy in assessing the functional capacity of spinal cord injuries.

Methods

This article is a systematic literature review whose objective was to identify references in the literature that allow understanding Neurofunctional Physiotherapy with regard to the concept of Spinal Cord Injury (SCI), classifications, diagnosis and treatment. Furthermore, we sought to analyze the assessment instruments used in clinical practice, the use of technologies and the relationship of influence in the quality of life item. To achieve this goal, the research questions (RQ) described in figure 1 were considered.

Figure 1 - Research Questions

Search strategy

In this type of work design, a compilation and analysis of data from several studies found in the literature was performed, following a strict protocol to minimize visualizations and exclude irrelevant or low-quality studies. The Scientific Electronic Library Online (SciELO), National Center for Biotechnology Information (PubMed), Latin American and Caribbean Literature in Health Sciences (LILACS) and Google Scholar databases were accessed from February 2022 to August 2022, to In the search, the following descriptors were used: “spinal cord injury”, “physiotherapy”, “International Classification of Functioning”, “scale”, “evaluation”, combined with each other using the Boolean AND descriptor. For the construction of the systematic review, the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol was used. The research was based on the following aspects (1) definition of the keywords, (2) designation of the search strings (3) search in the databases related to the theme (4) observation of the references of the chosen articles and (5) verification of the quality of the articles selected through the PEDro scale. Each section/topic of the systematic review aimed to answer the research questions mentioned in figure 1.

Selection criteria

The PRISMA methodology was applied in the review (figure 2) and in order to understandably answer the research questions, some parameters were established: (1) articles published in Portuguese, English and Spanish in the time interval between 2011 and 2021; (2) articles related to the research questions presented that had relevant data to answer them. On the other hand, the following ones were excluded from the research: self-reports, brief reports, case reports, unpublished work documents and abstracts.

Data transmission process

Data transmission was conducted according to each research question, looking for answers through useful information identified throughout the text. This is a systematic review, whose main intention is the analysis of articles related to the practice of Neurofunctional Physiotherapy in the evaluation process of patients after spinal cord injury in the last 10 years.

Conducting the theoretical framework

The assortment of articles was carried out independently by the author of the present article, between February 2022 and August 2022, by applying the strings in the databases. subsequently, duplicate works were removed and inclusion and exclusion criteria were applied to the remaining articles, which were analyzed according to title and abstract.

Analysis of the articles by the PEDro Scale

The 57 articles found for the research were analyzed according to the PEDro Scale by three evaluators, the third being to confirm the decision criterion. This scale aims to qualify studies that present a high probability of high internal validity, in the same way that it helps guide a clinical decision [5].

Analysis instruments

To choose the evaluative instruments, which will be discussed below, the frequency with which they appeared in the set of articles selected for the study was used as criteria (represented by the graph in figure 3), as well as the influence of these instruments in the physiotherapeutic performance in relation to patients with spinal cord injury (SCI) regarding gait analysis, sensory and motor function, quality of life and level of independence when performing external activities (basic and instrumental).

Figure 3 - Frequency of evaluation instruments found in the scientific repertoire

The International Classification of Functioning (ICF) applies to all people, not just those with functional limitations. The ICF describes the individual condition of being in association with the health domains - body structure and functions, activity and participation, in addition to contextualizing with personal and environmental factors, while the International Classification of Diseases (ICD-10) seeks to understand the etiology of diseases, in order to provide diagnoses or other health scenarios, complemented by ICF data [6].

Functional assessment is the ability to perform basic activities of daily living and self-care. The Functional Independence Measure Scale (FIM) multidimensionally evaluates the individual’s motor and cognitive practice in the following scenarios: eating, cleaning the body, dressing the upper and lower body regions, using the bathroom and controlling excretions, transfers (bed-bathtub /shower), locomotion, comprehension, language, social interaction, problem solving and memory. Each item ranges from 1 to 7, totaling 126 points, in which the lower the level reached, the greater the functional dependence.

The Spinal Cord Independence Measure (SCIM) is an internationally validated instrument that is very useful for evaluating spinal cord injured patients. This scale measures the independence of these patients when performing basic and instrumental activities of daily living, considering three subscales and in three domains with the evaluation of 19 tasks that cover personal care, movement, and respiratory and sphincter alterations. SCIM can be applied both in adult and elderly patients, as well as in different degrees and causes of spinal cord injury [7].

The Modified Ashworth Scale is used in patients with central nervous system injury in the evaluation of spasticity, it has easy and quick applicability, however it is a subjective evaluation without standardization regarding the speed of the applied movements, that is, the quantification of the score will depend on the analysis and the evaluator’s practice, because of this it is not considered a reliability scale [8]. According to studies at Thomas Jefferson University, the Walking Index for Spinal Cord Injury II (WISCI II) is used in clinical trials to measure improvements in gait in people with spinal cord injury. It is a functional limitation scale, not a disability scale. WISCI II must be used in a standardized environment with standardized equipment and definitions, which are observed and recorded by trained professionals [9].

The Medical Outcomes Study 36 - Item Short - Form Health Survey (SF-36) is an evaluative instrument for quality of life, which is simple to conduct and understand, it is multidimensional and consists of 36 items contained in 8 components: functional efficiency, vitality, biotype, pain, general health, social and emotional issues, and mental health. Its score ranges from 0 to 100 where the closer to 100, the better the patient’s health status [10].

The Berg Balance Scale contains 14 evaluative items with the primary purpose of measuring the risk of falling in the elderly population, extending to other pathologies such as spinal cord injury, in order to precede any reliability and validation assessments [11].

The Barthel Index (1965) quantitatively assesses the individual’s functional capacity to perform activities of daily living. In its modified version, independence in locomobility, personal hygiene and physiological actions are considered. In addition to being an evaluative instrument, it is used to predict length of stay and estimate prognosis. This index is classified as simple, valid and reliable; its score ranges from 100 to 0, where the degree of independence is defined by the highest score [8].

The American Spinal Injury Association (ASIA) scale, created in 1984 and underwent changes over the years until 2002, assesses the patient through sensory and motor scales. In the sensitive one, two types of sensitivity are stimulated: pain (through a delicate pin) and touch (in which the patient is touched with a tuft of cotton). The patient will describe the sensation as absent, normal or diminished and in deep pressure, he will classify it as absent or present. The total for the sensitive index corresponds to 112 points (56 for each type of sensitivity). On the motor scale, muscle strength is graded in degrees from 0 to 5, in which grade 3 corresponds to the normality of the muscle to be tested. Each hemibody totals 50 points, whose score varies from 0 to 5, characterizing, respectively, from paralysis to total counterresistance [12].

Results

As for the degree of injury, SCI affects the cervical and thoracic regions more regularly, with this the patient will develop different levels of dependence according to the injured site. If it reaches the C1-C4 region, the patient will have a condition of tetraplegia (partial or complete paralysis of the four limbs and trunk) at a high level, while at C5-C8 it will present the same condition at a lower level, that is, the first form of injury brings more severe complications [3, 2, 13, 7].

Studies carried out on the topic described that there is a higher incidence of spinal cord injuries in the age group between 10-32 years. Among the various difficulties reported by patients in relation to routine actions are: lack of accessibility in public environments, crowded means of transport, need for adaptations at home, which predisposes to the issue of resorting to companions [3].

When the injury occurs in the thoracic, lumbar or sacral region, there is paralysis of the lower limbs and trunk called paraplegia, that means, the person has a partial loss of motor and sensory skills. Those with injuries in the cervical region have tetraplegia that can partially or totally affect the upper and lower limbs and the trunk. Paraplegic individuals manage to maintain a certain level of independence, while quadriplegics can demonstrate greater functional independence through the use of appropriate and adapted orthopedic equipment [2, 7].

SCI rehabilitation occurs from the moment the diagnosis is discovered until the individual’s social reintegration [14]. Clinical management of the patient is driven by performance and measurement of present functional changes that may be significantly important. Through statistical analogies between the mean changes observed, the possible treatments to be applied originate [15]. For the professionals involved, it is challenging to keep up to date and explore new therapeutic resources such as the use of stem cells and robotics. It should be noted that in order to apply these new resources, high-quality evidence must be available in order to offer the patient a reliable recovery service [16].

Researchers have reported that the locomotion subdomain showed high levels of dependence, which is the most associated with quality of life [17]. The practice of physical exercises in spinal cord injured patients promotes the improvement of physical and cardiorespiratory capacities, in which there is progress in terms of coordination, resistance and muscle strength, being a reducing factor of cases of urinary tract infection, in addition to bedsores and hospitalizations [13, 3]. According to the research carried out by the researchers, it was noted that through the association between virtual games and the practice of physical exercises, therapeutic objectives can be achieved, since the movements performed by the patient are converted to virtual reality [2].

It was observed that those patients who adhered to physiotherapy during the hospital phase achieved functional improvements and increased life expectancy. In this way, the relevance of the applicability of evaluative scales is portrayed, which quantify and qualify the evolutions achieved by each patient. Unfortunately, there are still obstacles to collecting and displaying authentic data, so some scales need adjustments according to the clinical condition of the patient being treated [18].

The ASIA (specifies spinal cord injury) and SCIM (defines the level of autonomy) scales, according to the literature, are considered the most appropriate in terms of supervising the effects of the rehabilitation process in people with SCI. It was noticed the need to optimize the patient’s recovery in a timely manner, in order to improve the functional performance of this patient as well as reduce rehabilitation costs [19]. When practicing self-care, the aim is to provide the patient with a daily stimulus of the feeling of capacity, demonstrating the importance of their collaborative participation during the treatment, thus granting autonomy in routine activities in accordance with the patient’s clinical condition [20].

As explained in the table 1, the score obtained by the PEDro scale ranged from 0 to 10 depending on the type and quality of the study analyzed. It was noted that among the studies included for the production of the review, the highest score acquired was 10 and the average obtained was approximately 6.42.

Discussion

The present study aimed to analyze post-SCI functional capacity and the role of physiotherapy in the patient’s quality of life. The researchers, through their clinical practice, used SCIM II because version III requires more complexity due to the issue of measuring the concentration of excreted urine. This scale, when applied to patients waiting for arthrodesis surgery, shows a sudden functional loss as a result of the demand for rest or some factor related to the preoperative process. In the same study, it is noticed that as the ASIA does not assess the pattern of muscle strength, there are different classifications between the motor index and the functional capacity of the patient [19].

The FIM is “a reliable and sensitive instrument to changes related to self-care skills, locomotion, surgical interventions and research” [16]. Among the analyzed studies, the authors highlighted the FIM and the Barthel Index as general scales when considering functionality [21]. The studies report the ability of the ICF to help physiotherapy with regard to recording functional data, choosing interventions and recording the results obtained, in order to develop clinical practice. It was observed that, when performing physical therapy treatments, patients acquire positive developments in motricity, so the long wait in the hospital phase brings functional damage to these individuals [18].

Locomotor training brings benefits to individuals with partial and total spinal cord injury, in which it is possible to notice progress in walking even for those with low motor scores. For patients with more severe conditions, the use of robotic technology allows for longer training [22]. Studies show that by increasing the ability to perform physical exercises, patients have described improvements in quality of life in view of less fatigue at the end of daily activities, in addition to being able to maintain these actions for a longer time, acquiring more self-confidence [23].

The lack of physical exercise in these neurological patients has negative effects on the cardiorespiratory system. It was noticed that when using the cycle ergometer in rehabilitation, there was a reduction in respiratory alterations secondary to the injury, when applied after the clinical stabilization of the case - acute or chronic [13]. It is important to emphasize that the well-being of people with SCI is significantly associated with social and occupational insertion, as well as mobility [24]. When evaluating the quality of life of patients, it is essential to meet the individual needs of each one, especially when using certain instruments in different cultures [25].

Complementing rehabilitation with the use of virtual reality (VR) can provide more attractive treatments for those with SCI, especially those with quadriplegia, as it allows these people to interact with a stimulated and unstable environment, offering the user mastery of movements, activating as many regions as possible. As necessary based on the applied therapy and allowing the patient to choose during this process which games, characters and levels they prefer. In addition, virtual reality facilitates contact with other people, thus ensuring the improvement of self-esteem, positive experiences and socialization [15].

Berg’s balance scale is more sensitive to distinguish those patients who walk in the community without assistance to perform this action [26]. This scale proved to be valid when used simultaneously with other instruments such as WISCI and SCIM, however, it was not well related to the number of falls and was not considered discriminatory in terms of predicting falls in spinal cord injured patients [11].

The articles analyzed and included in the review presented, as a scientific repertoire, approaches regarding physical therapy practice in multidisciplinary actions in different areas of health, which involved outpatient clinics, clinics, hospitals, rehabilitation centers, as well as research carried out by other educational institutions. In the graph (figure 2) it can be seen that among the 57 articles found, five evaluative instruments were most used, namely: ASIA, FIM, ICF, Berg and SCIM. With this, the importance of functional analysis of the condition of patients with spinal cord injury is highlighted, as well as the participation of physiotherapy in the recovery process in order to guarantee, in a way, independence for these patients during their routine, both personal and professional.

Conclusion

Health care directed to patients with spinal cord injury is an important process for reintegration into the community, as well as a means of providing them with an emotional boost, in order to encourage the search for and confidence in carrying out an effective and satisfactory rehabilitation. In addition, it is worth mentioning how essential it is to provide the patient with treatment based on their individualities, in order to show that there is not only the “patient” to be treated, but that there is a human being in need of care (emotional, physical, psychosocial). Through this, the value of multidisciplinarity is portrayed during the health services provided in the public and private sectors.

Among the limitations presented in the study, there is the issue of the reduced number of articles that relate the functionality and independence of patients with spinal cord injury. Spinal cord injury and physiotherapeutic participation during rehabilitation is still little known and, in a way, not adequately explored, either because of the lack of incentives in the area or because of the difficulty in keeping patients with this clinical condition in constant monitoring and treatment. With this, it is necessary to carry out new scientific productions that take into account the different contexts that may affect the assiduity and collaboration of these patients throughout rehabilitation.

In this sense, Neurofunctional Physiotherapy can guide patients with spinal cord trauma towards a functional life. Adapting the home, workplace and leisure time are tasks that will help. Following the International Classification of Functioning model to assess and treat, as well as performing functional tasks are points that should be considered by the physiotherapist. The more physiotherapy consultations (and at all stages of health) the better the patient’s chances of recovery. Finally, other professionals are needed, such as doctors, speech therapists, psychologists, music therapists, among others.
