Proximal Bilateral Arm Transplantation with Left Shoulder Reconstruction: Outcomes at 24 Months.

Background: Arm transplantation has been proposed as a valid therapeutic option for arm amputees. A bilateral arm transplantation including reconstruction of the left shoulder was performed on January 13, 2021 in Lyon (France). Methods: The recipient was a 48-year-old man with bilateral amputation at proximal arm level on both sides following an electric shock in 1998. He had received a liver transplant in 2002. The donor was a 35-year-old man. On the right side, the donor humerus was fixed on the remaining 9-cm-long proximal stump, and was reinforced with the donor fibula in an intramedullary fashion. On the left side, the whole donor humerus (including the humeral head) was transplanted with reconstruction of the gleno-humeral joint, including a suspension ligamentoplasty. The immunosuppressive protocol was based on antithymocyte globulins as induction therapy, and tacrolimus, steroids and mycophenolate mofetil as maintenance therapy. Results: Good bone healing and a well-positioned ligamentoplasty on the left side were achieved. At 2 years, the recipient was able to flex both elbows, and wrist extension, finger flexion, and extension were appreciated on both sides. Intrinsic muscle activity was detectable by electromyography during the eighth posttransplant month, and sensitivity was recovered. The patient is satisfied with his autonomy in some daily activities, but his greatest satisfaction is the recovery of his body image. Conclusions: These results confirm that it is possible to propose this transplantation to proximal-level arm amputees. The patients' information about risks and limits as well as their compliance and determination remain important prerequisites.

Evaluation of the long-term effect of selective tibial neurotomy for the treatment of spastic foot using a personal goal-centered approach.

OBJECTIVE: The objective of this study was to evaluate the long-term effectiveness of selective tibial neurotomy (STN) for the treatment of the spastic foot using a goal-centered approach. METHODS: Between 2011 and 2018, adult patients with a spastic foot (regardless of etiology) who received STN followed by a rehabilitation program were included. The primary outcome was the achievement of individual goals defined preoperatively (T0) and compared at 1-year (T1) and 5-year (T5) follow-up by using the Goal Attainment Scaling methodology (T-score). The secondary outcomes were the presence of spastic deformities (equinus, varus, and claw toes), modified Ashworth scale (MAS) score for the targeted muscles, and modified Rankin Scale (mRS) score at T0, T1, and T5. RESULTS: Eighty-eight patients were included. At T5, 88.7% of patients had achieved their goals at least "as expected." The mean T-score was significantly higher at T1 (62.5 ± 9.5) and T5 (60.6 ± 11.3) than at T0 (37.9 ± 2.8) (p < 0.0001), and the difference between T1 and T5 was not significant (p = 0.2). Compared to T0, deformities (equinus, varus, and claw toes; all p < 0.0001), MAS score (p < 0.0001), and mRS score (p < 0.0001) were significantly improved at T1 and T5. Compared to T1, MAS score increased slightly only at T5 (p = 0.05) but remained largely below the preoperative value. There was no difference between T1 and T5 regarding other clinical parameters (e.g., deformities, walking abilities, mRS score). CONCLUSIONS: This study found that STN associated with a postoperative rehabilitation program can enable patients to successfully achieve personal goals that are sustained within a 5-year follow-up period.

Associations of coping and health-related behaviors with medical students' well-being and performance during objective structured clinical examination.

Objective structured clinical examination (OSCE) is a valid method to evaluate medical students' competencies. The present cross-sectional study aimed at determining how students' coping and health-related behaviors are associated with their psychological well-being and performance on the day of the OSCE. Fourth-year medical students answered a set of standardized questionnaires assessing their coping (BCI) and health-related behaviors before the examination (sleep PSQI, physical activity GPAQ). Immediately before the OSCE, they reported their level of instant psychological well-being on multi-dimensional visual analogue scales. OSCE performance was assessed by examiners blinded to the study. Associations were explored using multivariable linear regression models. A total of 482 students were included. Instant psychological well-being was positively associated with the level of positive thinking and of physical activity. It was negatively associated with the level of avoidance and of sleep disturbance. Furthermore, performance was negatively associated with the level of avoidance. Positive thinking, good sleep quality, and higher level of physical activity were all associated with improved well-being before the OSCE. Conversely, avoidance coping behaviors seem to be detrimental to both well-being and OSCE performance. The recommendation is to pay special attention to students who engage in avoidance and to consider implementing stress management programs.Clinical trial: The study protocol was registered on clinicaltrial.gov NCT05393206, date of registration: 11 June 2022.

Implicit and explicit motor imagery ability after SCI: Moving the elbow makes the difference.

Cervical spinal cord injury (SCI) causes dramatic sensorimotor deficits that restrict both activity and participation. Restoring activity and participation requires extensive upper limb rehabilitation focusing elbow and wrist movements, which can include motor imagery. Yet, it remains unclear whether MI ability is impaired or spared after SCI. We investigated implicit and explicit MI ability in individuals with C6 or C7 SCI (SCIC6 and SCIC7 groups), as well as in age- and gender-matched controls without SCI. Inspired by previous studies, implicit MI evaluations involved hand laterality judgments, hand orientation judgments (HOJT) and hand-object interaction judgments. Explicit MI evaluations involved mental chronometry assessments of physically possible or impossible movements due to the paralysis of upper limb muscles in both groups of participants with SCI. HOJT was the paradigm in which implicit MI ability profiles differed the most between groups, particularly in the SCIC6 group who had impaired elbow movements in the horizontal plane. MI ability profiles were similar between groups for explicit MI evaluations, but reflected task familiarity with higher durations in the case of unfamiliar movements in controls or attempt to perform movements which were no longer possible in persons with SCI. Present results, obtained from a homogeneous population of individuals with SCI, suggest that people with long-term SCI rely on embodied cognitive motor strategies, similar to controls. Differences found in behavioral response pattern during implicit MI mirrored the actual motor deficit, particularly during tasks that involved internal representations of affected body parts.

Association of Personality Traits With the Efficacy of Stress Management Interventions for Medical Students Taking Objective Structured Clinical Examinations.

PURPOSE: Personality traits are associated with psychophysiological stress, but few studies focus on medical students. This study aimed to better understand the association of personality traits with the efficacy of stress management interventions for medical students. METHOD: A randomized controlled trial was conducted with fourth-year students who took the objective structured clinical examination at Bernard University Lyon 1 in December 2021. Students were randomized in cardiac biofeedback, mindfulness, and control groups. Each intervention was implemented for 6 minutes before the examination. Physiological stress levels were collected during the intervention. Psychological stress levels were rated by students at baseline and after the intervention. Personality traits were assessed via the Big-Five Inventory. Interactions between personality traits and the efficacy of the interventions were analyzed using multivariable linear regression models. RESULTS: Four hundred eighty-one students participated. Higher baseline psychological stress levels were associated with higher neuroticism and agreeableness (ß = 10.27, 95% confidence interval (CI) [7.40, 13.13], P < .001 and ß = 3.42, 95% CI [0.98, 5.85], P = .006, respectively) and lower openness (ß = -4.95, 95% CI [-7.40, -2.49], P < .001). As compared to the control intervention, both stress management interventions led to lower levels of psychological (P < .001 for both) and physiological stress levels (biofeedback: P < .001 and mindfulness: P = .009). Biofeedback efficacy varied by extraversion score for psychological (ß = -5.66, 95% CI [-10.83, -0.50], P = .03) and physiological stress reduction (ß = -0.002, 95% CI [-0.003, -0.00004], P = .045). Mindfulness efficacy varied by agreeableness score for psychological stress reduction (ß = -7.87, 95% CI [-13.05, -2.68], P = .003). CONCLUSIONS: Students with a high score in extraversion may benefit more from biofeedback interventions, while students with high scores in agreeableness may benefit more from mindfulness interventions.

Interrater reliability in neurology objective structured clinical examination across specialties.

PURPOSE: To assess interrater reliability and examiners' characteristics, especially specialty, associated with scoring of neurology objective structured clinical examination (OSCE). MATERIAL AND METHODS: During a neurology mock OSCE, five randomly chosen students volunteers were filmed while performing 1 of the 5 stations. Video recordings were scored by physicians from the Lyon and Clermont-Ferrand university teaching hospitals to assess students performance using both a checklist scoring and a global rating scale. Interrater reliability between examiners were assessed using intraclass coefficient correlation. Multivariable linear regression models including video recording as random effect dependent variable were performed to detect factors associated with scoring. RESULTS: Thirty examiners including 15 (50%) neurologists participated. The intraclass correlation coefficient of checklist scores and global ratings between examiners were 0.71 (CI95% [0.45-0.95]) and 0.54 (CI95% [0.28-0.91]), respectively. In multivariable analyses, no factor was associated with checklist scores, while male gender of examiner was associated with lower global rating (ß coefficient = -0.37; CI 95% [-0.62-0.11]). CONCLUSIONS: Our study demonstrated through a video-based scoring method that agreement among examiners was good using checklist scoring while moderate using global rating scale in neurology OSCE. Examiner's specialty did not affect scoring whereas gender was associated with global rating scale.

Discriminative value of different combinations of tests to detect unilateral neglect in patients with right hemisphere damage.

BACKGROUND AND PURPOSE: This study was undertaken to assess the most sensitive combination of tests to detect peripersonal unilateral neglect (UN) after stroke. METHODS: The present study is a secondary analysis of a previously reported multicentric study of 203 individuals with right hemisphere damage (RHD), mainly subacute stroke, 11 weeks postonset on average, and 307 healthy controls. A battery of seven tests, providing 19 age- and education-adjusted z-scores, were given: the bells test, line bisection, figure copying, clock drawing, overlapping figures test, and reading and writing. Statistical analyses used a logistic regression and a receiver operating characteristic (ROC) curve after adjustment on demographic variables. RESULTS: A combination of four z-scores based on the following three tests provided good discrimination of patients with RHD from matched healthy controls: the starting point and the difference between the number of omissions on left and right sides from the bells test, rightward deviation in bisection of long lines (20 cm), and left-sided omissions in a reading task. The area under the ROC curve was 0.865 (95% confidence interval = 0.83-0.901), with sensitivity = 0.68, specificity = 0.95, accuracy = 0.85, positive predictive value = 0.90, and negative predictive value = 0.82. CONCLUSIONS: The most sensitive and parsimonious combination of tests to detect UN after stroke relies on four scores from three simple tests (bells test, line bisection, and reading). Future study is warranted to assess its ability to account for the functional difficulties of UN in daily life in the patient's actual environment.

Evaluation of Selective Tibial Neurotomy for the Spastic Foot Treatment Using a Personal Goal-Centered Approach: A 1-Year Cohort Study.

BACKGROUND: Selective tibial neurotomy (STN) has already demonstrated its effectiveness to reduce foot deformities and spasticity, but assessment according to a goal-centered approach is missing. OBJECTIVE: To evaluate the effectiveness of STN associated with a postoperative rehabilitation program for the treatment of the spastic foot, according to a goal-centered approach. METHODS: Interventional study (before-after STN and rehabilitation program) with observational design including consecutive adult patients with spastic foot, who received STN followed by a rehabilitation program, was performed. The primary outcome measure was the achievement of individual goals at the 1-year follow-up using the Goal Attainment Scaling methodology (with T-score). The secondary outcomes measures were the Modified Ashworth Scale and the modified Rankin Score. RESULTS: A total of 104 patients were included. At the 1-year follow-up, 228/252 (90.5%) goals were achieved: 62/252 (24.6%) were achieved as initially expected, 86/252 (34.1%) were achieved better than initially expected, and 80 (31.7%) were achieved much better than initially expected. The mean T-score was significantly increased at the 1-year follow-up (61.5 ± 10.5) compared with the preoperative period (38.1 ± 2.9, P < .00001), and 95/104 (91.3%) patients had a T-score ≥50, meaning that these patients have achieved their goals. At follow-up, spastic deformities were all significantly decreased ( P < .0001), the Modified Ashworth Scale was significantly lower for each muscle targeted ( P < .0001), and the modified Rankin Score was significantly decreased ( P < .0001) allowing the patient population to improve from a moderate to a slight disability status. CONCLUSION: This study showed that STN, associated with a postoperative rehabilitation program, successfully achieve personal goals in patients with spastic foot.

Factors associated with post-stroke social participation: A quantitative study based on the ICF framework.

BACKGROUND: Post-stroke social participation is a major determinant of quality of life and life satisfaction. However, few data relating to participation determinants are available, especially the influence of psychological factors and factors related to the living environment. OBJECTIVES: This study investigated determinants of post-stroke social participation within the International Classification of Functioning, Disability and Health framework. METHODS: We contacted people with stroke who had been hospitalized in the Rhône County, included in a previous cohort study, were aged ≥18 years and were not institutionalized. The primary outcome was social participation measured with the Stroke Impact Scale (SIS) 2.0. We performed multiple hierarchical linear regressions to test the following predictors: clinical factors (stroke-related variables, limitations in Activities of Daily Living [ADL]/Instrumental ADL), personal factors (sociodemographic factors, coping strategies) and environmental factors (satisfaction with social relationships and living environment). RESULTS: Among the 352 participants, 63% were men, and mean age was 68.7(SD 14.5) years. In the last multivariate model, variables associated with higher levels of social participation were the use of the positive thinking coping strategy (B (SD)=1.17(0.52), p = 0.03), higher perceived satisfaction with the living environment (B (SD)=0.17(0.07), p = 0.03) and fewer perceived activity limitations (B (SD)=0.55 (0.06), p < 0.001). Conversely, the seeking social support coping style (B (SD)= -1.98 (0.60), p = 0.001), and a higher number of stroke-related sequelae (B (SD)= -1.93(0.53), p = 0.001) were associated with lower social participation. CONCLUSIONS: The identification of potentially modifiable personal and environmental factors that influence social participation provides elements to strengthen existing rehabilitation programs and opens the way for possible psychosocial interventions.

Rehabilitation professionals' views on individual peer support interventions for assisting stroke survivors with reintegration into the community: a qualitative study.

PURPOSE: We aimed to explore stroke rehabilitation professionals' understanding and representations of peer support; the benefits they anticipated for patients; and the levers and barriers they perceived to implement the intervention in their practice. MATERIALS AND METHODS: This qualitative study comprised four focus groups with 21 rehabilitation professionals and four semi-structured interviews. It was held in a French hospital. Interpretation was guided by the Consolidated Framework for Implementation Research. RESULTS: Although professionals had poor knowledge on peer support, they identified many unmet needs of stroke survivors that peer support could meet such as social, emotional and informational support. Main barriers were the lack of human and financial resources, and of linkage between hospital and community professionals, and the fear that peer support would give false hope to survivors if not delivered properly. They showed ambivalence towards patient engagement, acknowledging its importance, but demonstrating top-down attitudes. They also identified potential avenues for the implementation of peer support for stroke survivors. CONCLUSIONS: Our study supports the necessity to involve professionals in the construction of peer-support interventions and to sensitise them to provide patient-centred care. It delivers insights on effective implementation strategies to develop peer support interventions for stroke survivors reintegrating the community.

Stroke survivors experience many difficulties especially when transitioning from hospital to home, in which peer-support could be helpful.Success of peer-support interventions rely on the collaboration of healthcare professionals with peer supporters.Individual peer-support might be useful for stroke survivors in the following key dimensions: healthcare pathway orientation, social/administrative procedures, emotional support, informational support, informal caregivers support.Rehabilitation departments planning to implement individual peer-support, should consider supporting and training both the team and the peer-supporters to work together and adopt partnership postures.

Case Report: True Motor Recovery of Upper Limb Beyond 5 Years Post-stroke.

Most of motor recovery usually occurs within the first 3 months after stroke. Herein is reported a remarkable late recovery of the right upper-limb motor function after a left middle cerebral artery stroke. This recovery happened progressively, from two to 12 years post-stroke onset, and along a proximo-distal gradient, including dissociated finger movements after 5 years. Standardized clinical assessment and quantified analysis of the reach-to-grasp movement were repeated over time to characterize the recovery. Twelve years after stroke onset, diffusion tensor imaging (DTI), functional magnetic resonance imaging (fMRI), and transcranial magnetic stimulation (TMS) analyses of the corticospinal tracts were carried out to investigate the plasticity mechanisms and efferent pathways underlying motor control of the paretic hand. Clinical evaluations and quantified movement analysis argue for a true neurological recovery rather than a compensation mechanism. DTI showed a significant decrease of fractional anisotropy, associated with a severe atrophy, only in the upper part of the left corticospinal tract (CST), suggesting an alteration of the CST at the level of the infarction that is not propagated downstream. The finger opposition movement of the right paretic hand was associated with fMRI activations of a broad network including predominantly the contralateral sensorimotor areas. Motor evoked potentials were normal and the selective stimulation of the right hemisphere did not elicit any response of the ipsilateral upper limb. These findings support the idea that the motor control of the paretic hand is mediated mainly by the contralateral sensorimotor cortex and the corresponding CST, but also by a plasticity of motor-related areas in both hemispheres. To our knowledge, this is the first report of a high quality upper-limb recovery occurring more than 2 years after stroke with a genuine insight of brain plasticity mechanisms.

Assessing the implementation of community-based learning in public health: a mixed methods approach.

BACKGROUND: The French government has set up a community-based learning programme on health promotion for undergraduate health students to involve them in key public health objectives. At the University of Lyon, students first underwent formal instruction, including e-learning, lectures, and interactive seminars, and then became health educators for school pupils. The main objective of the present study was to assess the process of implementing this programme during the 2018-2019 academic year. METHODS: The satisfaction and perception of medical and midwife students with community-based learning experiences were assessed by a questionnaire, semi-directive interviews, and observations. Replies to the questionnaire were described by median and interquartile range or by proportion. A paired Wilcoxon-Mann-Whitney test was used to compare self-evaluated students' competence scores before and after the seminars (alpha risk of 5%). Thematic analyses using grounded theory were performed on recorded and transcribed interviews, and on transcribed notes taken during the observations. RESULTS: Over time the students have evolved from a negative perception of the community-based learning to a positive one. The students were mostly satisfied by interactive seminars that allowed them to gain confidence and competencies in health education. Their involvement in the programme increased their self-esteem. They became more aware of their educative responsibilities regarding public health issues as future professionals. CONCLUSIONS: The students had a positive perception of the implementation of a community-based learning programme in our University, as it appeared a pertinent strategy to raise their awareness of prevention and health education issues.

Multiprofessional intervention to improve adherence to medication in stroke patients: a study protocol for a randomised controlled trial (ADMED AVC study).

INTRODUCTION: Adherence to secondary preventive medications is often suboptimal in patients with stroke, exposing them to an increased risk of recurrent cerebral and/or cardiovascular events. Effective actions in the long term to improve adherence to medication are needed. The study will evaluate the efficacy of a collaborative multiprofessional patient-centred intervention conducted by a pharmacist on adherence to secondary preventive medication in stroke survivors. METHODS AND ANALYSIS: This is a multicentre cluster-randomised controlled trial. Two groups of 91 patients (intervention vs standard care) will be recruited. The clinical pharmacist intervention targeting secondary preventive medication will consist of three parts over 1 year: (1) an individual semi-structured interview at hospital discharge; (2) follow-up telephone interviews at 3, 6 and 9 months after discharge; and (3) a final individual semi-structured interview 1 year after discharge. Information on patient follow-up will be shared with the general practitioner and the community pharmacist by sending a report of each interview. The primary outcome is adherence to medication during the 12 months after hospital discharge, assessed using a composite endpoint: the medication possession ratio associated with a self-administered questionnaire. ETHICS AND DISSEMINATION: The local ethics committee, the national committee for use of personal data in medical research and the national data protection agency approved the study. The sponsor has no role in study design; collection, analysis and interpretation of data; or report writing. DISCUSSION: This pharmacist-led educational programme has the potential to significantly improve adherence to medication in stroke survivors which could lead to a decrease in recurrent cerebral and/or cardiovascular events. TRIAL REGISTRATION NUMBER: NCT02611440.

Determining the Interrater Reliability of the SOFMER Activity Score (version 2) for Individuals in Rehabilitation Centers.

OBJECTIVE: To assess the interrater reliability of the SOFMER Activity Score (SAS) (version 2 [v2], an 8-item [4 motor and 4 cognitive] and 5-level scale) and improve its scoring system before conducting further validation steps. DESIGN: Cross-sectional, prospective, observational, noninterventional, and multicentric study. SETTING: The study was conducted between November 2018 and September 2019 in 4 French rehabilitation centers (2 public university hospitals for adults and 2 private not-for-profit rehabilitation centers for children). PARTICIPANTS: The study included 101 participants (N=101; mean age, 44.5±25.4 years; 28.7% younger than 18 and 18.8% older than 65 years). The female/male sex ratio was 0.6. The causes for admission to the center were mainly neurologic (65%) or orthopedic (24%). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Activity limitation was rated with the SAS the same day by 2 independent multidisciplinary teams. The interrater reliabilities of the score items were assessed using weighted kappa coefficients. RESULTS: All weighted kappa coefficients ranged between 0.83 and 0.92, indicating "good" to "excellent" interrater reliability. Interteam score disagreements occurred in 227 of 808 scores (28%). The reason for most disagreements was unnoticed human or material aid during the observation period. CONCLUSIONS: The results demonstrate the high interrater reliability of the SASv2 and allow carrying out further validation steps after minor changes to item scoring instructions and clearer definitions of some items that help improving scoring standardization. The SASv2 may then become a consistent measure of activity level for clinical research or burden of care investigations.

Effects of prismatic adaptation on balance and postural disorders in patients with chronic right stroke: protocol for a multicentre double-blind randomised sham-controlled trial.

INTRODUCTION: Patients with right stroke lesion have postural and balance disorders, including weight-bearing asymmetry, more pronounced than patients with left stroke lesion. Spatial cognition disorders post-stroke, such as misperceptions of subjective straight-ahead and subjective longitudinal body axis, are suspected to be involved in these postural and balance disorders. Prismatic adaptation has showed beneficial effects to reduce visuomotor disorders but also an expansion of effects on cognitive functions, including spatial cognition. Preliminary studies with a low level of evidence have suggested positive effects of prismatic adaptation on weight-bearing asymmetry and balance after stroke. The objective is to investigate the effects of this intervention on balance but also on postural disorders, subjective straight-ahead, longitudinal body axis and autonomy in patients with chronic right stroke lesion. METHODS AND ANALYSIS: In this multicentre randomised double-blind sham-controlled trial, we will include 28 patients aged from 18 to 80 years, with a first right supratentorial stroke lesion at chronic stage (≥12 months) and having a bearing ≥60% of body weight on the right lower limb. Participants will be randomly assigned to the experimental group (performing pointing tasks while wearing glasses shifting optical axis of 10 degrees towards the right side) or to the control group (performing the same procedure while wearing neutral glasses without optical deviation). All participants will receive a 20 min daily session for 2 weeks in addition to conventional rehabilitation. The primary outcome will be the balance measured using the Berg Balance Scale. Secondary outcomes will include weight-bearing asymmetry and parameters of body sway during static posturographic assessments, as well as lateropulsion (measured using the Scale for Contraversive Pushing), subjective straight-ahead, longitudinal body axis and autonomy (measured using the Barthel Index). ETHICS AND DISSEMINATION: The study has been approved by the ethical review board in France. Findings will be submitted to peer-reviewed journals relative to rehabilitation or stroke. TRIAL REGISTRATION NUMBER: NCT03154138.
