Body image and perception among adults with and without phantom limb pain

Feasibility study of a home-based graded motor imagery intervention (GraMI protocol) for amputees with phantom limb pain

INTRODUCTION

Phantom limb pain affects 64% of amputees. Graded Motor Imagery comprises three consecutive application techniques designed to reorganize maladaptive changes that have occurred after the amputation.

OBJECTIVE

To assess the feasibility of a home-based Graded Motor Imagery intervention, the GraMI protocol, for amputee people with phantom limb pain.

METHODS

Twenty individuals over 18 years of age with upper or lower limb amputation, experiencing phantom limb pain, who were pharmacologically stable, and had been discharged from the hospital were recruited. The experimental group followed the GraMI protocol. Primary outcomes included study processes, such as recruitment time and rate, adherence, compliance, and the acceptability of digital technologies as a treatment tool. Secondary outcomes assessed the impact on phantom limb pain, quality of life, functionality, and depressive symptoms.

RESULTS

On average, seven participants were recruited monthly over a three-month period. No losses were recorded throughout the nine weeks of intervention. Treatment adherence averaged 89.32%, and all participants demonstrated familiarity with the usability of digital technologies. No significant differences were observed between groups (p = .054). However, within the experimental group, intragroup analysis revealed a significant (p = .005) and clinically relevant reduction (>2 points) with a large effect size (0.89) in phantom limb pain.

CONCLUSION

Conducting a multicenter study with a home-based intervention using the GraMI protocol is feasible. Future clinical trials are needed to verify its effectiveness in managing phantom limb pain.

The German adaptation of the Amputee Body Image Scale and the importance of psychosocial adjustment to prosthesis use

Negative cognitions related to one's own body, here referred to as body image disturbances (BID), are common after lower limb amputation and correlate with weak psychological functioning. The Amputee Body Image Scale (ABIS) is internationally used to assess BID in persons with lower limb amputation. However, there is no psychometrically evaluated German adaptation available. Including a sample of 191 individuals with lower limb amputation, the present study developed and psychometrically evaluated the German ABIS. Results suggest high reliability in terms of internal consistency and stability of the measure over two years. Meaningful and significant relationships to sex, amputation level, post-amputation pain, mobility, and psychopathology indicate validity of the instrument. Multivariate analyses emphasize a specific and inverse relationship between BID and psychosocial adaptation to the prosthesis including its embodiment. Focussing on ABIS items that are independent of the type of amputation or rehabilitation experiences resulted in an ABIS short form with psychometric properties comparable to the long form. This instrument could be prospectively used in diverse limb loss populations, such as individuals with upper limb amputation or persons not using a prosthesis. The present results thus crucially contribute to the repertoire of patient-reported outcome measures in the context of post-amputation rehabilitation.

Effectiveness of telerehabilitation-based structured exercise program in individuals with unilateral transtibial amputation: a randomized controlled study

PURPOSE

The study aimed to compare the effects of home exercise alone and telerehabilitation combined with home exercise in individuals with transtibial amputation.

MATERIALS AND METHODS

The telerehabilitation group (n = 24) received telerehabilitation combined with home exercise, while the control group (n = 24) received home exercise alone. Outcomes included the timed up-and-go (TUG) test and the 30-second chair-stand test (30CST), the Activities-specific Balance Confidence (ABC) Scale, the Trinity Amputation and Prosthesis Experience Scales (TAPES), the Amputee Body Image Scale (ABIS), and the Nottingham Health Profile (NHP). The analysis used a 2 × 2 mixed repeated measures ANOVA.

RESULTS

The group-by-time interactions were significant for TUG (p = 0.002, F[1;41] = 10.74) and 30CST (p = 0.001, F[1;41] = 11.48). The mean difference (6th week-baseline) was -0.49 for TUG and 0.95 for 30CST in the telerehabilitation group and -0.14 for TUG and 0.13 for 30CST in the control group. There were statistically meaningful group-by-time interactions on the ABC (p = 0.0004, F[1;41] = 14.47), the TAPES-activity restriction (p = 0.0001, F[1;41] = 28.96), TAPES-prosthesis satisfaction (p = 0.004, F[1;41] = 9.19), and the NHP (p = 0.0002, F[1;41] = 16.07) favoring the telerehabilitation group.

CONCLUSIONS

Telerehabilitation combined with home exercise can offer greater benefits in improving gait, muscle strength, balance confidence, activity restriction, prosthesis satisfaction, and quality of life compared to home exercise alone for individuals with transtibial amputation.Implications for rehabilitationExercise helps individuals with lower limb amputation overcome their physical limitations and enables them to use their prostheses effectively.Physiotherapy and rehabilitation after amputation are not at the desired level, and individuals with lower limb amputation encounter various difficulties in accessing physiotherapy.Telerehabilitation has great potential to facilitate access to physiotherapy for individuals with amputation and reduce resource utilization.In a relatively small sample of amputees, this study shows that telerehabilitation-based exercise improves physical health and quality of life.

Prostheses and Rehabilitation Principles in Pediatric Limb Deficiency

Pediatric limb loss or limb deficiency is uncommon in the United Sates occurring 1 per 1943 live births per year, with a ratio of 2:1 upper to lower extremity.1 Causes include congenital limb deficiency, and less frequently, limb loss secondary to trauma, cancer, or other illnesses. Vascular disruption, particularly as seen in amniotic band syndrome, stands as the leading suspect in the multifaceted and intricate causes of congenital limb loss. Children with limb difference and deficiency present unique medical and rehabilitation challenges. Physical Medicine and Rehabilitation (PM&R) physicians are uniquely equipped to navigate these complexities. Prosthetic prescription and fabrication for children require balancing scientific principles with individual needs. A "one-size-fits-all" approach is ineffective. Many diverse factors impact prosthetic prescription and fabrication, including amputation level, residual limb characteristics, cognitive/developmental age, family goals, financial resources, and medical literacy.

The relationships between body image, self-esteem and quality of life in adults with trauma-related limb loss sustained in the Syrian war

BACKGROUND

Numerous military soldiers have lost limbs as a result of the Syrian War. While there are variations between trauma-related amputations in military and civilian populations, both scenarios result in life-changing injuries.

OBJECTIVE

To explore the relationship between body image, self-esteem, and quality of life (QOL) domains following trauma-related major amputation. It will be the first study in Syria on the correlation between self-esteem and body image. It will help improve our quality of care to meet patient needs and increase well-being, which in turn will help to address body image, self-esteem, and QOL.

METHOD

A cross-sectional study that recruited 235 soldiers with amputations in two centers and two military hospitals in Latakia and Tartous. Patients were given an 81-item questionnaire that included the Amputee Body-Image Scale (ABIS), the Rosenberg Self-esteem (RSE) scale, the WHOQOL-BREF questionnaire, and unidimensional pain measures. The ANOVA test, a student's t-test, multiple linear regression, internal consistency, and test-retest reliability were utilized for statistical analysis.

RESULTS

There was a strong relationship between body image, self-esteem, and QOL, with the presence of body image concerns significantly associated with lower self-esteem scores and lower QOL scores (p=0.001). Patients with phantom pain sensation had significantly reduced self-esteem (p =0.001), greater body image concerns (p =0.001), and lower scores in all domains of QOL. We found that body image and self-esteem impacted the psychological, social, and environmental domains. After controlling for pain level and number of co-morbid conditions, body image and self-esteem did not predict WHOQOL-BREF scores, with the exception of the environmental domain, where no pain and low self-esteem predicted better environmental domain scores.

CONCLUSION

Patients' body image and self-esteem were greatly impacted by lower-limb amputations. Additionally, phantom pain further impacted self-esteem, body image, and QOL. The image of the body had a profound effect on psychological, social, and environmental domains, and self-esteem was influenced by almost all aspects of QOL.

Case Report: Phantom limb pain relief after cognitive multisensory rehabilitation

Introduction

Relieving phantom limb pain (PLP) after amputation in patients resistant to conventional therapy remains a challenge. While the causes for PLP are unclear, one model suggests that maladaptive plasticity related to cortical remapping following amputation leads to altered mental body representations (MBR) and contributes to PLP. Cognitive Multisensory Rehabilitation (CMR) has led to reduced pain in other neurologic conditions by restoring MBR. This is the first study using CMR to relieve PLP.

Methods

A 26-year-old woman experienced excruciating PLP after amputation of the third proximal part of the leg, performed after several unsuccessful treatments (i.e., epidural stimulator, surgeries, analgesics) for debilitating neuropathic pain in the left foot for six years with foot deformities resulting from herniated discs. The PLP was resistant to pain medication and mirror therapy. PLP rendered donning a prosthesis impossible. The patient received 35 CMR sessions (2×/day during weekdays, October-December 2012). CMR provides multisensory discrimination exercises on the healthy side and multisensory motor imagery exercises of present and past actions in both limbs to restore MBR and reduce PLP.

Results

After CMR, PLP reduced from 6.5-9.5/10 to 0/10 for neuropathic pain with only 4-5.5/10 for muscular pain after exercising on the Numeric Pain Rating Scale. McGill Pain Questionnaire scores reduced from 39/78 to 5/78, and Identity (ID)-Pain scores reduced from 5/5 to 0/5. Her pain medication was reduced by at least 50% after discharge. At 10-month follow-up (9/2013), she no longer took Methadone or Fentanyl. After discharge, receiving CMR as outpatient, she learned to walk with a prosthesis, and gradually did not need crutches anymore to walk independently indoors and outdoors (9/2013). At present (3/2024), she no longer takes pain medication and walks independently with the prosthesis without assistive devices. PLP is under control. She addresses flare-ups with CMR exercises on her own, using multisensory motor imagery, bringing the pain down within 10-15 min.

Conclusion

The case study seems to support the hypothesis that CMR restores MBR which may lead to long-term (12-year) PLP reduction. MBR restoration may be linked to restoring accurate multisensory motor imagery of the remaining and amputated limb regarding present and past actions.

Cortical Reorganization after Limb Loss: Bridging the Gap between Basic Science and Clinical Recovery

Despite the increasing incidence and prevalence of amputation across the globe, individuals with acquired limb loss continue to struggle with functional recovery and chronic pain. A more complete understanding of the motor and sensory remodeling of the peripheral and central nervous system that occurs postamputation may help advance clinical interventions to improve the quality of life for individuals with acquired limb loss. The purpose of this article is to first provide background clinical context on individuals with acquired limb loss and then to provide a comprehensive review of the known motor and sensory neural adaptations from both animal models and human clinical trials. Finally, the article bridges the gap between basic science researchers and clinicians that treat individuals with limb loss by explaining how current clinical treatments may restore function and modulate phantom limb pain using the underlying neural adaptations described above. This review should encourage the further development of novel treatments with known neurological targets to improve the recovery of individuals postamputation.Significance Statement In the United States, 1.6 million people live with limb loss; this number is expected to more than double by 2050. Improved surgical procedures enhance recovery, and new prosthetics and neural interfaces can replace missing limbs with those that communicate bidirectionally with the brain. These advances have been fairly successful, but still most patients experience persistent problems like phantom limb pain, and others discontinue prostheses instead of learning to use them daily. These problematic patient outcomes may be due in part to the lack of consensus among basic and clinical researchers regarding the plasticity mechanisms that occur in the brain after amputation injuries. Here we review results from clinical and animal model studies to bridge this clinical-basic science gap.
