RESUMEN
Background: Lower limb amputation is an emotionally devastating condition that causes a complete change in the quality of life, may lead to phantom limb pain in most of the cases, and puts the individual in a high risk of developing psychological disorders. The objective of this study is to evaluate the consequence of adding virtual reality (VR) to a traditional exercise program on pain, mental status, and psychological status in traumatic unilateral lower limb amputees (LLAs). Methods: Thirty-two traumatic LLAs were randomly assigned into two equal groups in this randomized control trial. Participants did accomplish a postfitting exercise program at least 6 months before enrolment; the control group (CG) underwent a traditional rehabilitation program, and experimental group (EG) had the same program, in addition to VR training. Data were collected before and after 6 weeks of intervention using visual analog scale (VAS) for pain, Beck's depression inventory (BDI) for depression, and 12-item short form survey for mental health summary (MHS) and physical health summary (PHS). Results: Thirty-two amputees (29 males and 3 females) were included with mean age in CGs and EG (27.6 ± 4) and (27.6 ± 7.6) years, respectively. Postintervention, the VAS score was significantly reduced only in EG (P = 0.003). Both groups showed significant improvement in BDI, MHS, and PHS (P < 0.05). However, the EG showed a superior significance in BDI and MHS scores (P < 0.05). There was no significance between groups in PHS score. Conclusion: Adding VR to conventional training is beneficial in decreasing pain and in improving depression and MHS of traumatic unilateral LLAs.

Mirror therapy is a widely used treatment for phantom limb pain (PLP) relief in patients with limb loss. Less common is progressive muscle relaxation (PMR), used mostly in other medical conditions (psychological, terminal cancer pain, etc). The purpose of this study is to evaluate the efficacy of a mirror therapy preceded by PMR intervention compared to mirror therapy preceded by unguided generic relaxation-mirror therapy in patients with lower limb amputation suffering from PLP. This pilot study was a single-blind, controlled, randomized trial. Thirty lower limb amputees suffering from PLP were recruited and randomly assigned to three groups respectively undergoing a PMR-mirror therapy rehabilitative intervention, generic relaxation-mirror therapy, and conventional physiotherapy (ConvPT). Selected items from Prosthesis Evaluation Questionnaire (PEQ) and the Brief Pain Inventory (BPI) were used to test the pain features at the beginning and 1â week after 3â weeks of intervention. A decrease of about 65% was found in the rate and duration of PLP at the PEQ in PMR-mirror therapy with respect to generic relaxation-mirror therapy (about 30%) and ConvPT (about 6%). A decrease of about 90% in intensity (worst and average) of PLP in PMR-mirror therapy when compared to generic relaxation-mirror therapy (about 45%) and ConvPT (about 20%) was found at the BPI. We preliminary concluded, albeit with limitations due to the small sample of patients, that mirror therapy can improve PLP when associated with PMR. Further studies are required to confirm that PMR could be an effective technique for more successful PLP management.

PURPOSE: First time examination of the physical and psychological long-term outcome following traumatic hemipelvectomy. METHODOLOGY: In this study, all patients suffering from traumatic hemipelvectomy that were treated in a level-A trauma center since 1988 were retrospectively evaluated. The authors aimed to compare the physical and psychological outcome following primary amputation (A) vs. limb-preservation (LP) procedures. The patients were examined with a focus on pain, function, mobility and general health. As part of this examination, various scores were recorded, i.e., Majeed Score, Time up & Go or SF-36. RESULTS: The following work showed 13 patients who had suffered a traumatic hemipelvectomy, 8 of whom survived. Five of these were available for subsequent clinical re-examination; of these, three patients underwent an amputation, while limb preservation was performed on two patients. Mean follow-up of the amputee group was after 12 years compared to 6.5 years following limb preservation. After limb preservation, both patients reported phantom limb pain at the affected leg, despite pain medication. The general state of health was assessed as 82/100 (A) and 45/100 (LP). The Majeed score was 61 (A) vs. 45 (LP). In the clinical examination, three out of five patients (2 LP, 1 A) showed peroneal palsy (PP). In the quality-of-life analysis based on the SF12/36 and the NHP, amputees scored higher than the patients who underwent limb preservation surgery. CONCLUSION: In our small patient cohort, satisfaction, pain and mobility tend to be better following primary amputation compared to limb preserving surgery.

INTRODUCTION: Phantom limb syndrome is a debilitating complication after extremity amputation that poses significant challenges to recovery. This study aims to examine the relationship between phantom limb syndrome and mental and physical comorbidities, including a comparison between phantom limb pain and phantom limb syndrome without pain in below knee amputees. METHODS: This is a retrospective cohort study of patients who underwent below knee amputation of the lower extremity in the PearlDiver database, as identified using CPT codes. Analysis was carried out to evaluate the absence or presence of phantom limb syndrome. Matched bivariate analysis accounting for age, sex, Charlson Comorbidity Index score, and region was used to assess whether the presence of pain in phantom limb syndrome patients was associated with increased comorbidity. RESULTS: In total, 44,028 patients with below knee amputation were examined: 95% (42,493 patients) did not develop phantom limb syndrome while 4.8% (1,535 patients) of patients did develop phantom limb syndrome. Phantom limb syndrome was significantly associated with increased odds of coexistent major depressive disorder (OR = 1.86, p <0.0001), generalized anxiety disorder (OR = 2.14, p = 0.04), posttraumatic stress disorder (OR = 1.7, p <0.0001), suicidal ideation (OR = 1.62, p <0.0001), obesity (OR = 1.28, p = 0.0007), osteoarthritis (OR = 1.53, p <0.0001), osteoporosis (OR = 1.64, p <0.0001), and low back pain (OR = 2.31, p <0.0001). Analysis of patient cohorts of phantom limb syndrome with pain and those without pain did not reveal a statistically significant relationship between the presence of pain and any dependent variable. CONCLUSIONS: This investigation of over 44,000 patients with below knee amputation revealed that patients with phantom limb syndrome exhibit significantly higher rate of psychiatric comorbidities compared to those without documented phantom limb pain. Suicidal ideation, major depressive disorder, generalized anxiety disorder, and post-traumatic stress disorder were especially common, and consequently a multi-disciplinary approach to management is essential.

Introduction: Many patients affected by bone and soft tissue tumors, undergo amputation surgery and report the sensation and/or pain of the phantom limb. Objective: Identify, summarize and discuss studies on the psychological aspects of the phantom limb phenomenon in oncological patients who underwent amputation surgery. Method: Integrative review of the literature published in the last 25 years. Experimental studies, clinical trials and literature review were searched in the databases MEDLINE, LILACS and Embase. Results: Seven articles were selected for this review. Three studies established correlations between psychological factors and the occurrence of the phantom limb phenomenon after amputation, four addressed psychological and emotional aspects involved in the amputation surgery and psychological aspects involved in the phantom limb phenomenon, however, they did not establish relationships among them. Some authors defend the correlation between psychological aspects and the occurrence of the phantom limb phenomenon in amputee patients. Its neurophysiological explanation remains unknown to the scientific community. Conclusion: The phantom limb phenomenon can be influenced by psychological and emotional aspects caused by the illness and its treatment. Further studies about the phenomenon in cancer patients are necessary, especially about the psychological aspects, given its relevance in cancer care

El presente texto tiene como propósito interrogar la afirmación lacaniana de la angustia como afecto que no engaña. Para tal propósito, iniciaremos revisando las últimas elaboraciones freudianas sobre la angustia localizables en el texto "Inhibición, síntoma y angustia", para luego ubicar en el seminario La angustia ciertas coordenadas allí desarrolladas por Lacan, como es la de la angustia como señal de lo real, su relación al objeto a, al falo y al fantasma; así como la propuesta de fin de análisis más allá de la angustia de castración. Posteriormente, propondremos que en Lacan podemos ubicar dos modos de presentarse la angustia: una, que engaña, en su articulación al fantasma y a la angustia de castración; otra, que no engaña, en consonancia con el significante de la falta en el Otro en términos de desamparo. Finalmente, ubicamos algunas consecuencias para la práctica analítica, al denotar la articulación del deseo del analista con la angustia vía el acto, y señalando que no distinguir en el análisis las dos manifestaciones de la angustia previamente denotadas, resulta engañoso para el analista al confundir la detención del análisis con su finalización
The purpose of this text is to interrogate the Lacanian affirmation of anguish as an affect that does not deceive. For this purpose, we will begin by reviewing the latest Freudian elaborations on anguish that can be found in the text "Inhibition, Symptom and Anguish", and then locate in the Seminar The anguish certain coordinates developed there by Lacan, such as that of anguish as a sign of what it is real, its relation to object a, phallus and phantasy; as well as the proposal for the end of the analysis beyond castration's anguish. Later, we will propose that in Lacan we can locate two ways of presenting anguish: first one, which deceives in its articulation the phantasy and the anguish of castration; another one, which does not deceive in relation with the signifier of the lack in the Other in terms of helplessness. Finally, we locate some consequences for analytical practice by denoting the articulation of the analyst´s desire with anguish by the means of the act, and pointing out that not distinguishing in the analysis the two previously denoted manifestations of anguish, is misleading for the analyst by confusing the stop of the analysis with its completion

Phantom limb pain (PLP) may be relieved using a visual representation of an intact limb. However, patients with distorted (telescoped) phantoms seem unable to associate with visualizations of intact limbs. A virtual arm visualization was matched to the individual's phantom perception and controlled in an augmented reality (AR) intervention. Seven PLP participants with telescoped phantoms performed 8 supervised home-based AR-training sessions (45 minutes each) within 2 weeks. The virtual arm was superimposed in AR onto their residual limb and controlled using electromyography from the residual limb. AR-training sessions included 3 AR tasks aimed at reengaging the neural circuits related to the lost limb. Agency (Rubber hand illusion questionnaire) and telescoping (proprioceptive drift and felt telescoping) were monitored after individual training sessions. fMRI during lip pursing was assessed before and after intervention. Pain rating index scores were reduced by 52% (mean changeâ¯=â¯-1.884, Pâ¯=â¯.032, dâ¯=â¯1.135). Numerical rating scale scores of PLP severity (0-6) in patients benefitting from the intervention were reduced by 41% (mean changeâ¯=â¯.93 Pâ¯=â¯.022, dâ¯=â¯1.334). The lip pursing task illustrated decreased cortical activity in the primary somatosensory cortex, which correlated to the reduced numerical rating scale scores of PLP severity. PERSPECTIVE: Two weeks of novel AR interventions in patients with telescoped phantoms demonstrated reduced PLP and reversal of cortical reorganization. This research highlights the potential of individualized AR interventions for PLP and indicate the importance of agency in this type of treatments.

The field of malignant hematology has experienced extraordinary advancements with survival rates doubling for many disorders. As a result, many life-threatening conditions have since evolved into chronic medical ailments. Paralleling these advancements have been increasing rates of complex hematologic pain syndromes, present in up to 60% of patients with malignancy who are receiving active treatment and up to 33% of patients during survivorship. Opioids remain the practice cornerstone to managing malignancy-associated pain. Prevention and management of opioid-related complications have received significant national attention over the past decade, and emerging data suggest that patients with cancer are at equal if not higher risk of opioid-related complications when compared with patients without malignancy. Numerous tools and procedural practice guides are available to help facilitate safe prescribing. The recent development of cancer-specific resources directing algorithmic use of validated pain screening tools, prescription drug monitoring programs, urine drug screens, opioid use disorder risk screening instruments, and controlled substance agreements have further strengthened the framework for safe prescribing. This article, which integrates federal and organizational guidelines with known risk factors for cancer patients, offers a case-based discussion for reviewing safe opioid prescribing practices in the hematology setting.

In this case study, we investigated the efficacy of mirror therapy and online counseling in the management of phantom limb pain. The patient was a 28-year-old woman who experienced phantom limb pain after a traumatic transhumeral amputation three and a half months before initiating therapy. After a 40-minute educational session with a nurse researcher experienced in pain management and surgical nursing, the patient practiced mirror therapy at home for four weeks and kept in contact with the nurse using a mobile chat application. The patient scored the intensity of her pain before and after each practice session on a 0-to-10 numeric pain scale. The first week was difficult for her because of tiredness and the pain. In the second week she experienced less pain during the day than at night but claimed to feel much better than before. In the fourth week, she reported having difficulty sleeping, but she stated that her pain had decreased. The intensity of the pain didn't change following mirror therapy in the first week; however, her average pain score was 1.15 points lower after mirror therapy in the second week (from 4.57 to 3.42), and 1.57 points lower in the third and fourth weeks (from 5.42 to 3.85 and 4.85 to 3.28). Online counseling for mirror therapy is easy, economical, and time-saving for patient and nurse alike. However, physical and physiological problems experienced during this process may reduce the effectiveness of the therapy, highlighting the importance of a multidisciplinary approach to phantom limb pain management, which may include care from a psychologist, massage therapist, physiotherapist, and specialist in alternative therapies for relaxation, in addition to the surgeon and the nurse.

BACKGROUND: Deep brain stimulation (DBS) has been considered for patients with intractable pain syndromes since the 1950s. Although there is substantial experience reported in the literature, the indications are contested, especially in the United States where it remains off-label. Historically, the sensory-discriminative pain pathways were targeted. More recently, modulation of the affective sphere of pain has emerged as a plausible alternative. OBJECTIVE: To systematically review the literature from studies that used contemporary DBS technology. Our aim is to summarize the current evidence of this therapy. METHODS: A systematic search was conducted in the MEDLINE, EMBASE, and Cochrane libraries through July 2017 to review all studies using the current DBS technology primarily for pain treatment. Study characteristics including patient demographics, surgical technique, outcomes, and complications were collected. RESULTS: Twenty-two articles were included in this review. In total, 228 patients were implanted with a definitive DBS system for pain. The most common targets used were periaqueductal/periventricular gray matter region, ventral posterior lateral/posterior medial thalamus, or both. Poststroke pain, phantom limb pain, and brachial plexus injury were the most common specific indications for DBS. Outcomes varied between studies and across chronic pain diagnoses. Two different groups of investigators targeting the affective sphere of pain have demonstrated improvements in quality of life measures without significant reductions in pain scores. CONCLUSION: DBS outcomes for chronic pain are heterogeneous thus far. Future studies may focus on specific pain diagnosis rather than multiple syndromes and consider randomized placebo-controlled designs. DBS targeting the affective sphere of pain seems promising and deserves further investigation.

OBJECTIVE: To describe the development of a virtual reality (VR) treatment for phantom limb pain (PLP) and phantom sensations and provide feasibility data from testing the treatment in a population of veterans. DESIGN & SUBJECTS: Fourteen participants completed a baseline visit evaluating their amputation, PLP, and phantom sensations. Subsequently, participants completed a VR treatment modeled after mirror therapy for PLP, navigating in a VR environment with a bicycle pedaler and motion sensor to pair their cadence to a VR avatar. The VR avatar enabled visualization of the participant's intact phantom limb in motion, a hypothesized mechanism of mirror therapy. SETTING: Laboratory. METHODS: Participants completed pre- and post-treatment measures to evaluate changes in PLP, phantom sensations, and rate helpfulness, realism, immersion, adverse experiences, and treatment satisfaction. RESULTS: Eight of 14 participants (57.1%) reported PLP pre-VR treatment, and 93% (13/14) reported one or more unpleasant phantom sensations. After treatment, 28.6% (4/14) continued to report PLP symptoms (t[13] = 2.7, P = 0.02, d = 0.53) and 28.6% (4/14) reported phantom sensations (t[13] = 4.4, P = 0.001, d = 1.7). Ratings of helpfulness, realism, immersion, and satisfaction were uniformly high to very high. There were no adverse experiences. Four participants completed multiple VR treatments, showing stable improvements in PLP intensity and phantom sensations and high user ratings. CONCLUSIONS: This feasibility study of a novel VR intervention for PLP was practical and was associated with significant reductions in PLP intensity and phantom sensations. Our findings support continued research in VR-based treatments in PLP, with a need for direct comparisons between VR and more established PLP treatments.

INTRODUCTION: Chronic pain and reduced function are significant problems for Military Service members and Veterans following amputation. Peripheral nerve stimulation (PNS) is a promising therapy, but PNS systems have traditionally been limited by invasiveness and complications. Recently, a novel percutaneous PNS system was developed to reduce the risk of complications and enable delivery of stimulation without surgery. MATERIALS AND METHODS: Percutaneous PNS was evaluated to determine if stimulation provides relief from residual and phantom limb pain following lower-extremity amputation. PNS leads were implanted percutaneously to deliver stimulation to the femoral and/or sciatic nerves. Patients received stimulation for up to 60 days followed by withdrawal of the leads. RESULTS: A review of recent studies and clinical reports found that a majority of patients (18/24, 75%) reported substantial (≥50%) clinically relevant relief of chronic post-amputation pain following up to 60 days of percutaneous PNS. Reductions in pain were frequently associated with reductions in disability and pain interference. CONCLUSIONS: Percutaneous PNS can durably reduce pain, thereby enabling improvements in quality of life, function, and rehabilitation in individuals with residual or phantom limb pain following amputation. Percutaneous PNS may have additional benefit for Military Service members and Veterans with post-surgical or post-traumatic pain.

Corporeal awareness of body unity, continuity, and integrity is hardwired in the brain, even following massive deafferentation. Following peripheral limb injury, referred phantom sensations are reported frequently on the cheek and, rarely, on the ear. Here, we explore how brain plasticity mechanisms induced by multisensory stimulation of different facial regions (cheek and ear) modulate the feeling that a complete missing limb is still attached to the body. We applied the modified rubber hand illusion (RHI) paradigm following synchronous and asynchronous stimulation of the face-hand and ear-hand in the unusual case of a patient with a brachial plexus lesion, who had lost upper-left limb sensation and developed a phantom sensation of the arm restricted to the ear. He experienced a strong illusion of ownership of the rubber hand during synchronous stroking of the ear but not the cheek and reported more defined tactile sensations in his previously numb body part during the illusion than when simply touching the ear. Phantom experiences are not exclusively based on sensory memories of the once-present body periphery, they are organized into a topographic cortical map with the ear-hand area adjoining but separate from the face. Multimodal experiences specifically modulate possible remapping of ear-hand representations and generate a more defined connection between the brain's memory of the body and what one feels of the actual physical body. We suggest that RHI is a form of sensory intervention that makes the best use of residual signals from disconnected body parts after peripheral injury, evoking and controlling the limb sensations.

Phantom limb (PLP) as well as residual limb pain (RLP) are still a very significant problem after amputation and their causes are only partially known. Here we tested whether the predisposition for the frequency, duration and intensity of PLP and RLP is shared with other prior chronic pains and/or the presence of postamputation subacute pain. A week preoperatively we collected data using validated questionnaires, a pain diary and interviews on past chronic pain conditions, acute pain, depression, anxiety, pain interference, life control, social support and affective distress and pain ratings one day before the amputation in 52 patients scheduled for limb amputation. In the week postamputation and again three and 12 months thereafter, we collected data on postoperative wound pain, PLP, RLP and non-painful phantom sensation (PLS). Phantom and residual limb pain indices were calculated per patient, integrating the intensity, frequency and duration of past chronic pain, PLP, RLP and PLS into a single value to index the overall burden of pain. We report that acute and chronic pain long before but not on the day before the amputation and subacute pain postamputation significantly predicted up to half of the variance in the incidence and severity of PLP, RLP and PLS 12 months postamputation. Moreover, the severity of these painful sensations at 12 months postamputation was partially predicted by preamputation scores of depression and anxiety. These findings corroborate the hypothesis that chronic pain and non-painful sensations following limb amputation are strongly related to longstanding preoperative chronic pain and to subacute postoperative pain as well as to psychological factors before the amputation that may be inherited and/or acquired (learning- and memory-related). Furthermore, we also confirm that subacute pain postamputation comprises an additional risk factor for long-term painful sensations postamputation. Our results suggest that timely interventions might prevent the development of chronic pain.

BACKGROUND: During regional anesthesia, including combined spinal and epidural anesthesia (CSEA), patients may develop a perceptual alteration of limb position known as phantom limb syndrome (PLS). We aimed to identify factors that influence the PLS onset, to explore whether PLS predisposes to other postoperative symptoms, and to document the relationship between PLS and sensorimotor impairment during recovery. METHODS: Psychological questionnaires for anxiety and depression were completed beforehand, then multimodal tests of sensory and motor function, especially tests of proprioception, were performed regularly afterward. Two hundred participants undergoing elective gynecological surgery under CSEA reported their experiences of PLS and other symptoms using Likert rating scales. RESULTS: Prolonged preoperative fasting (odds ratio (OR) 2.34; 95% confidence intervals (CI) 1.21-4.52), and surgical history (OR 2.56; 95% CI 1.16-5.62) predisposed to PLS, but patients with more extensive anesthetic histories may be at lower risk (OR 0.57; 95% CI 0.31-1.08). Furthermore, significant correlations were observed between the recovery from PLS and the perception of joint movement within the deafferented area (Râ=â0.82, Pâ<â.01) and motor functions (Râ=â0.68). PLS increases the chance of experiencing postoperative fatigue, physical discomfort, and emotional upset. CONCLUSION: This study is the first to have identified the risk factors for PLS, assessed the relationship between PLS and postoperative sensorimotor impairment, and its influence on postoperative complications.

AIM: Limb amputation traumatically alters body image. Sensations rapidly prevail that the limb is still present and 85% of patients portray phantom limb pain. Throughout the testimonies of amputated patients with intense phantom limb pain, we show the difficulty in treating this chronic pain with current pharmacological and nonpharmacological therapies. PATIENTS & METHODS: We qualitatively analyzed the therapeutic choices of five amputees, the effectiveness of the treatments chosen and the impact on patients' quality-of-life. RESULTS & CONCLUSION: In general, patients who are refractory to pharmacological treatments are in favor of trying alternative therapies. It is therefore crucial to design a combined and personalized therapeutic plan under the coordination of a multidisciplinary team for the wellbeing of the patient.
