An Overview of the Bodily Awareness Representation and Interoception: Insights and Progress in the Field of Neurorehabilitation Research

In the last two decades, the scientific literature on so-called body representations has been increasing, and the notion of body awareness (BA) is particularly interesting for neurorehabilitation. In this article, we present results derived from recent studies on this representation, considering the different definitions and explicative models proposed as well as the empirical settings used to test it, providing an extensive overview of these issues. This article discusses the challenge of understanding how we integrate the sensory experiences of proprioception (knowing where our body is in space) and interoception (sensing internal bodily sensations, like hunger of thirst) with our perception of self. This is a difficult problem to analyze because our awareness of our body is inherently linked to our perspective, since the body is the means through which we interact with the world. Presenting the different viewpoints offered by recent theories on this concern, we highlighted that the neurorehabilitation and psychiatric settings offer two important fields useful for the study of BA because in them it is possible to analyze bodily representations by inducing/observing a controlled discrepancy between dysfunctional content and sensory inputs.

Key constructs of body awareness impairments post-stroke: a scoping review of assessment tools and interventions

PURPOSE

To summarise body awareness assessment tools and interventions relevant for stroke rehabilitation using a framework that categorises key body awareness constructs, disorders and impairments.

MATERIALS AND METHODS

Online electronic databases and trial registries were searched from inception until July 2021, in addition to hand searching reference lists of included studies and reviews. Study selection included any study design where the investigation involved assessing and/or intervening in body awareness following stroke. Data were extracted based on predefined criteria by two independent reviewers and mapped to the emergent framework.

RESULTS

The final analysis included 144 papers that reported 43 assessment tools and 8 types of interventions for body awareness. Consensus was reached on a synthesised body awareness framework. This comprised specific impairments and disorders, constructs, sub-categories and main categories leading to the overarching term of body awareness. Clinical and psychometric properties of the assessment tools were not reported or poorly evaluated, and the interventions lacked robust study designs and rigorous methods.

CONCLUSIONS

The framework produced will enable future research and clinical practice to be based on consistent concepts and definitions. Clinicians can also use this information to cautiously select assessment tools and/or interventions but are reminded of the limitations identified in this review.Implications for rehabilitationThere is limited understanding, compounded by inconsistent terminology and definitions regarding body awareness after stroke.A synthesized framework to define key constructs and definitions of body awareness is proposed.Assessment tools and interventions reported in the literature are mapped to the proposed framework.Psychometric properties of available tools are reported.Significant work remains to refine concepts of body awareness, develop and evaluate assessment tools and interventions.

Recovery of Body Awareness After Stroke: An Observational Study

Background: Body awareness (BA) is a process that involves sensory awareness originating from the body's physiological states, processes and actions, and is shaped by one's attitudes, perceptions, beliefs and experience of social and cultural context. Impairments in body awareness after stroke are believed to be common and may be an important influence on recovery outcomes. However, recovery of body awareness is poorly understood and receives little consideration in rehabilitation.

Aims: To investigate if body awareness changes over time following stroke; and identify if body awareness after stroke is associated with sensation, motor impairment, self-efficacy and quality of life.

Methods: An exploratory longitudinal observational study was performed. Participants with a stroke diagnosis and associated motor impairment were recruited from an acute stroke unit. An assessment battery consisting of sensory and motor impairment and function, body awareness, self-efficacy and quality of life measures were used at baseline, 1, 3 and 6 months.

Results: A total of 105 people with stroke were recruited. Most recovery in sensation and body awareness occurred within the first month after stroke (all p < 0.01). Sensation and body awareness were correlated with other clinical outcomes (motor impairment, self-efficacy and quality of life), demographics, and stroke specific clinical characteristics (all p < 0.01).

Conclusions: This is the first study to track recovery of body awareness after stroke and investigate the relationship it may have in recovery of sensation, motor impairment and function, self-efficacy and quality of life. Further research is now warranted to continue investigation of body awareness and to develop effective stroke-specific assessment and intervention strategies.

Dance Intervention Using the Feldenkrais Method Improves Motor, and Non-Motor Symptoms and Gait in Parkinson's Disease: A 12-Month Study

Objective

The aim of this study was to assess the effects of dancing (using the Feldenkrais method) on motor and non-motor symptoms, quality of life (QoL), and objective parameters of gait at the time of intervention and at the end of the 1-year study period.

Methods

This was a single-arm study in which 12 subjects with Parkinson’s disease (PD) received dance intervention during a 6-month period. Objective motor scales, gait analysis, and questionnaires on non-motor symptoms were evaluated at baseline and at 3, 6, and 12 months.

Results

Dance intervention decreased motor scale (Unified Parkinson’s Disease Rating Scale and Tinetti scale) scores and improved gait disturbance (gait velocity and step length) without increasing levodopa equivalent dose. Furthermore, dancing decreased non-motor scale (Non-Motor Symptoms Scale and Montgomery-Asberg Depression Rating Scale) scores and improved QoL.

Conclusion

Our findings suggest that dance intervention can be a complementary management method for PD patients.

United States Guild Certified Feldenkrais Teachers®: a survey of characteristics and practice patterns

Background

Feldenkrais Method® teachers help students improve function and quality of life through verbally and manually guided lessons. The reasons people seek Feldenkrais® lessons are poorly understood. Similarly, little is known about practice characteristics and patterns. To address these knowledge gaps, we conducted an extensive survey of United States Guild Certified Feldenkrais Teachers®.

Methods

We invited all Feldenkrais Teachers to participate in this survey delivered in web-based or print formats. We obtained overall and question-specific response rates, descriptive statistics, chi-square tests of response bias, and performed qualitative thematic review of comments.

Results

Overall response rate was 30.5% (392/1287). Ninety percent of responders had college degrees in diverse fields; 12.5% had credentials outside health care, 36.9% held conventional health care licenses, and 23.1% had complementary and alternative medicine credentials. Mean age was 55.7 years; most teachers were women (83%). California (n = 100) and New York (n = 34) had the most teachers. Forty-five percent of teachers earned ≤ 20% of their gross income from their practices, while 26% earned > 80%. Most saw < 10 students/week for individual lessons and < 10 students/week for group lessons. Students were mostly women (71.1%) and 45–64 years old. The primary reason students sought Feldenkrais lessons was pain. A quarter of students self-referred, a fifth were referred by conventional health care providers, and two-thirds paid for services directly. Themes from comments included: beliefs that Feldenkrais training had important personal and professional benefits for teachers; recognition of the challenges of operating small businesses and succinctly describing the Feldenkrais Method; the variety of practice approaches; and a deep commitment to the Feldenkrais Method.

Conclusions

Most Feldenkrais Teachers were well educated, often held additional credentials, were located in the West, were women, were older than 50 years, and had part-time practices. Most students were women, were adults, came from various referral sources, and paid directly for services. Teachers and students utilized the Feldenkrais Method in diverse settings and applications. These findings may foster practice development by Feldenkrais Teachers, improve communication between health care consumers and providers and assist decision-making, and stimulate more research concerning the Feldenkrais Method.

Patient-centered integrated motor imagery delivered in the home with telerehabilitation to improve walking after stroke

BACKGROUND AND PURPOSE

This case report describes the clinical reasoning process used to examine a person after stroke and intervene with a novel integrated motor imagery treatment designed for the rehabilitation of walking and delivered in the home through telerehabilitation. The integrated motor imagery treatment consisted of patient-centered goal setting and physical practice combined with motor and motivational imagery.

CASE DESCRIPTION

The patient was a 38-year-old woman who had had a diffuse left subarachnoid hemorrhagic stroke 10 years earlier. She lived independently in an assisted living complex and carried a straight cane during long walks or in unfamiliar environments. Examination revealed a slow gait speed, reduced walking endurance, and decreased balance confidence. Although she was in the chronic phase, patient-centered integrated motor imagery was predicted to improve her community mobility. Treatment sessions of 45 to 60 minutes were held 3 times per week for 4 weeks. The practiced tasks included transitioning from sitting to standing, obstacle clearance, and navigation in interior and exterior environments; these tasks were first executed and then imagined at ratios of 1:5. Task execution allowed the creation of a scene based on movement observation. Imagery scenarios were customized to address the patient's goals and observed movement problems. Motivational elements of arousal, problem solving, and reward were embedded in the imagery scenarios. Half of the sessions were provided on site, and the remaining sessions were delivered remotely. Seven sessions were delivered by the clinician in the home, and 5 sessions were delivered using telerehabilitation.

OUTCOMES

Improvements in motor imagery ability, gait parameters, and balance were observed after training. Most gains were retained at the 3-month follow-up. Compared with on-site delivery, the telerehabilitation sessions resulted in less therapist travel time and cost, as well as shorter therapy sessions.

DISCUSSION

The delivery of integrated motor imagery practice for walking recovery was feasible both on site and remotely.

Does the Feldenkrais Method make a difference? An investigation into the use of outcome measurement tools for evaluating changes in clients

Evidence-based practice confirms the need for outcome measures. Feldenkrais Method practitioners struggle to use such tools because of the broad range of applications of the Feldenkrais Method and the difficulty identifying suitable measurement tools. A pre/post-test design was used to investigate the use of three outcome measurement tools [Patient-specific Functional Scale (PSFS), Pain Outcome Profile (POP) and Short Form12v2 Health questionnaire (SF12v2)] for clients experiencing problems performing everyday functional tasks who attended Feldenkrais sessions. Eleven Feldenkrais practitioners submitted data on 48 clients. Changes were detected in the clients' ability to perform everyday tasks (PSFS improved 3.8 points, p < 0.001), levels of pain decreased (POP improved in current pain p = 0.001, physical index p < 0.001 and affective index p = 0.001) and quality of life improved significantly in six of the eight SF12v2 domains. These three tools have been found to be suitable for detecting changes in client function before and after a series of Feldenkrais sessions.

Feldenkrais Method balance classes are based on principles of motor learning and postural control retraining: a qualitative research study

BACKGROUND

Feldenkrais Method balance classes have been found to be effective in improving balance in recent studies, but there has been little research into possible mechanisms behind the effectiveness of these classes. Indeed, there has been little research into the content of any balance training classes.

OBJECTIVES

To analyse the content of a series of Feldenkrais Method balance classes to gain an understanding of how the results in these studies may have been achieved and the principles through which the method may be effective.

DESIGN

Qualitative research approach (content analysis).

METHOD

Feldenkrais Method Awareness Through Movement lessons were transcribed and the contents were analysed. An intercoder reliability study was undertaken.

RESULTS

The content analysis revealed that the classes used motor skill acquisition elements of internal feedback, repetition and variability of practice using an exploratory learning approach. Postural control skills of intersegmental coordination of ankle/hip/trunk synergies were practised, with control of the centre of mass over the base of support explored in anterior/posterior, medio/lateral, diagonal, rotational and circular directions. Key findings were the extensive involvement of trunk flexibility and control in the balance activities, and also the intensive attention to internal feedback which was linked to body awareness training.

CONCLUSION

The Awareness Through Movement lessons contained many elements consistent with current theories of motor skill acquisition and postural control, providing a sound theoretical basis for the effectiveness of the Feldenkrais approach in improving balance. The methodology used in this study may provide a useful model for similar investigations into other balance training approaches.

A preliminary survey of the practice patterns of United States Guild Certified Feldenkrais PractitionersCM

Background

The Feldenkrais Method^® of somatic education purports to guide people of varying ages and abilities to improve function. Many people choose this method to aid with recovery from injury, manage chronic conditions, or enhance performance even though limited research supporting its safety and effectiveness exists to guide decisions about use and referral. Very little information about practitioner characteristics and practice patterns is publicly available to assist researchers in the design of appropriate safety and effectiveness studies. The purpose of this study was to obtain an initial overview of the characteristics of United States Guild Certified Feldenkrais Practitioners^CM.

Methods

Of 1300 certified Feldenkrais^® practitioners at the time of the study, there were 1193 practitioners with email accounts who were sent invitations to complete a web-based survey. The survey inquired about practice locations, additional credentials, service patterns and workloads during the previous 3 months. Response rate and descriptive statistics were calculated.

Results

The survey had a 32.3% (385/1193) response rate. The top states in which responders practiced were California (n = 92) and New York (n = 44). Most responders did not hold other credentials as traditional health care providers or as complementary and alternative medicine providers. Among those who did, the most common credentials were physical therapist (n = 83) and massage therapist (n = 38). Just over a third of traditional health care providers only provided Feldenkrais lessons, compared to 59.3% of complementary and alternative providers. On average, responders saw 7.6 ± 8.1 (median = 5) clients per week for individual lessons, 8.4 ± 11.5 (median = 5) clients per week for group lessons, and 2.9 ± 3.9 (median = 2) new clients per month for individual lessons.

Conclusions

This preliminary survey of United States Guild Certified Feldenkrais Practitioners indicated that most practiced in the west and northeast, did not hold additional credentials, and had part-time practices. Those who were traditional health care providers were more likely than complementary and alternative medicine providers in other areas to combine their services. These results provide a foundation for further analyses of Feldenkrais practitioner characteristics and practice patterns that can aid the design of safety and effectiveness studies, and enhance use and referral decision-making.

Lengthening the hamstring muscles without stretching using "awareness through movement"

BACKGROUND AND PURPOSE

Passive stretching is widely used to increase muscle flexibility, but it has been shown that this process does not produce long-term changes in the viscoelastic properties of muscle as originally thought. The authors tested a method of lengthening hamstring muscles called "Awareness Through Movement" (ATM) that does not use passive stretching.

SUBJECTS

Thirty-three subjects who were randomly assigned to ATM and control groups met the screening criteria and completed the intervention phase of the study.

METHODS

The ATM group went through a process of learning complex active movements designed to increase length in the hamstring muscles. Hamstring muscle length was measured before and after intervention using the Active Knee Extension Test.

RESULTS

The ATM group gained significantly more hamstring muscle length (+7.04 degrees ) compared with the control group (+1.15 degrees ).

DISCUSSION AND CONCLUSION

The results suggest that muscle length can be increased through a process of active movement that does not involve stretching. Further research is needed to investigate this finding.
