Association of traumatic brain injury and Alzheimer disease onset: A systematic review / J. Julien in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - P. 347-356 Titre : Association of traumatic brain injury and Alzheimer disease onset: A systematic review Type de document : texte imprimé Auteurs : J. Julien, Auteur ; M.-C. Ferland, Auteur ; S. Joubert, Auteur Année de publication : 2017 Article en page(s) : P. 347-356 Langues : Anglais (eng) Français (fre) Mots-clés : Traumatisme crânien  Démence Alzheimer  Trouble mémoire  Démence  Coma  Traumatic brain injury,Concussion,Alzheimer disease,Loss of consciousness,Post-traumatic amnesia,Glasgow coma scale score,Severity,Dementia,Outcome,Review Résumé : Background: Inconsistencies regarding the risk of developing Alzheimer disease after traumatic brain injury (TBI) remain in the literature. Indeed, why AD develops in certain TBI patients while others are unaffected is still unclear. Objective: The aim of this study was to performed a systematic review to investigate whether certain variables related to TBI, such as TBI severity, loss of consciousness (LOC) and post-traumatic amnesia (PTA), are predictors of risk of AD in adults. Methods: From 841 citations retrieved from MEDLINE via PubMed, EMBASE, PSYINFO and Cochrane Library databases, 18 studies were eligible for the review. Results: The review revealed that about 55.5% of TBI patients may show deteriorated condition, from acute post-TBI cognitive deficits to then meeting diagnostic criteria for AD, but whether TBI is a risk factor for AD remains elusive. Conclusions: Failure to establish such a link may be related to methodological problems in the studies. To shed light on this dilemma, future studies should use a prospective design, define the types and severities of TBI and use standardized AD and TBI diagnostic criteria. Ultimately, an AD prediction model, based on several variables, would be useful for clinicians detecting TBI patients at risk of AD.

Barriers to physical activity in coronary artery disease patients: Development and validation of a new scale / Charles Joussain in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 289-298 Titre : Barriers to physical activity in coronary artery disease patients: Development and validation of a new scale Type de document : texte imprimé Auteurs : Charles Joussain, Auteur ; Davy Laroche, Auteur ; Julie Joubert, Auteur Année de publication : 2017 Article en page(s) : p. 289-298 Langues : Anglais (eng) Français (fre) Mots-clés : Questionnaire  Activité physique  Artère  Questionnaire,Barriers,Physical activity,Coronary artery disease,Validity,Reliability Résumé : Objective: To develop and validate a self-report questionnaire to measure barriers to regular physical activity (PA) in patients with stable coronary artery disease (CAD). Methods: Phase 1: 17 patients completed a semi-structured interview. After grouping and reformulating the reported barriers, their pertinence was reevaluated by the patients. Then, a decision algorithm was used to select items. A principal component analysis was performed to determine content validity. Phase 2: 49 patients completed the questionnaire resulting from phase 1 twice, 7 days apart, and questionnaires to evaluate depression, anxiety, and the level of physical activity. Construct validity was evaluated by analysis of Spearman's correlation coefficient between the total score for the questionnaire and a convergent dimension (anxiety), as well as a divergent dimension (Dijon physical activity score). Internal consistency was evaluated by Cronbach's alpha coefficient. Test-retest reliability was evaluated by the intraclass coefficient (ICC). Results: Eleven items were selected after phase 1. The questionnaire presented good face validity and the content validity seemed satisfactory after analysis of the literature by the experts. Construct validity was moderate. Internal consistency was very good (Cronbach's α>0.81). Reproducibility was excellent with an ICC at 0.95. Feasibility was good with less than 3 minutes to complete the questionnaire. Conclusion: This questionnaire presents good psychometric properties. A further prospective study should evaluate sensitivity to change and help determine a threshold value indicating the need for a specific behavioral strategy to alleviate barriers to physical activity in these patients.

Participant and service provider perceptions of an outpatient rehabilitation program for people with acquired brain injury / Frédérique Poncet in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 334-340 Titre : Participant and service provider perceptions of an outpatient rehabilitation program for people with acquired brain injury Type de document : texte imprimé Auteurs : Frédérique Poncet, Auteur ; Marie-Eve Lamontagne, Auteur ; Pascale Pradat-Diehl, Auteur Année de publication : 2017 Article en page(s) : p. 334-340 Langues : Anglais (eng) Français (fre) Mots-clés : Analyse  Rééducation fonctionnelle  Qualité  Technique mesure  SWOT analysis,Rehabilitation,Service delivery,Quality,Outcome,Measurement Résumé : Background: A holistic, intensive and interdisciplinary rehabilitation program for people with acquired brain injury (ABI) was developed at the Pitié-Salpêtrière Hospital, France (5 days/week for 7 weeks). This program, recently demonstrated effective, aimed to optimize the ability of people with ABI to perform activities and improve their participation by using individual and group interventions involving ecologically valid activities inside (e.g., in the gym and kitchen) and outside the hospital. However, the perception of the quality of the program by participants and service providers has not yet been reported. Objectives: This study had 3 objectives: (1) report the perception of participants (adults with ABI) in terms of service quality of the program, (2) report the strengths, weaknesses, opportunities, and threats (SWOT analysis) of the program as perceived by service providers, and (3) triangulate findings to draw conclusions about the program's quality and provide recommendations for quality improvement. Methods: We used a mixed-methods design with a validated questionnaire (Perception of Quality of Rehabilitation Services [PQRS-Montreal]) and interviews (structured around a SWOT analysis) involving program participants and service providers. Results: We included 33 program participants (mean age 43.6 years) and 12 service providers (mean years with program 7.6 years). In general, study participants showed a convergence of opinion about the high quality of the program, particularly regarding the team and its participant-focused approach. Specific aspects of the program were viewed more negatively by both participants and service providers (i.e., addressing sexuality, family involvement and return to work/volunteer work/school). Conclusion: Participant and service provider perceptions of the rehabilitation program under study were generally positive. A reliable and valid questionnaire and interviews helped identify aspects of the program that worked well and those that could be targeted for future quality improvement.

Patellar tendon vibration reduces the increased facilitation from quadriceps to soleus in post-stroke hemiparetic individuals / Eric Maupas in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 319-328 Titre : Patellar tendon vibration reduces the increased facilitation from quadriceps to soleus in post-stroke hemiparetic individuals Type de document : texte imprimé Auteurs : Eric Maupas, Auteur ; Sibele de Andrade Melo, Auteur ; Joseph-Omer Dyer, Auteur Année de publication : 2017 Article en page(s) : p. 319-328 Langues : Anglais (eng) Français (fre) Mots-clés : Accident cérébrovasculaire  Hémiplégie  Stroke,Hemiparesis,Vibration,Heteronymous facilitation,Spasticity,Coactivation Résumé : Background: Stimulation of the femoral nerve in healthy people can facilitate soleus H-reflex and electromyography (EMG) activity. In stroke patients, such facilitation of transmission in spinal pathways linking the quadriceps and soleus muscles is enhanced and related to co-activation of knee and ankle extensors while sitting and walking. Soleus H-reflex facilitation can be depressed by vibration of the quadriceps in healthy people, but the effects of such vibration have never been studied on the abnormal soleus facilitation observed in people after stroke. Objectives: To determine whether vibration of the quadriceps can modify the enhanced heteronymous facilitation of the soleus muscle observed in people with spastic stroke after femoral nerve stimulation and compare post-vibration effects on soleus facilitation in control and stroke individuals. Methods: Modulation of voluntary soleus EMG activity induced by femoral nerve stimulation (2*motor threshold) was assessed before, during and after vibration of the patellar tendon in 10 healthy controls and 17 stroke participants. Results: Voluntary soleus EMG activity was facilitated by femoral nerve stimulation in 4/10 (40%) controls and 11/17 (65%) stroke participants. The level of facilitation was greater in the stroke than control group. Vibration significantly reduced early heteronymous facilitation in both groups (50% of pre-vibration values). However, the delay in recovery of soleus facilitation after vibration was shorter for the stroke than control group. The control condition with the vibrator turned off had no effect on the modulation. Conclusions: Patellar tendon vibration can reduce the facilitation between knee and ankle extensors, which suggests effective presynaptic inhibition but decreased post-activation depression in the lower limb of people after chronic hemiparetic stroke. Further studies are warranted to determine whether such vibration could be used to reduce the abnormal extension synergy of knee and ankle extensors in people after hemiparetic stroke.

Quantifying cardiorespiratory responses resulting from speed and slope increments during motorized treadmill propulsion among manual wheelchair users / Cindy Gauthier in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 281-288 Titre : Quantifying cardiorespiratory responses resulting from speed and slope increments during motorized treadmill propulsion among manual wheelchair users Type de document : texte imprimé Auteurs : Cindy Gauthier, Auteur ; Ludivine Ananos, Auteur ; Murielle Grangeon, Auteur Année de publication : 2017 Article en page(s) : p. 281-288 Langues : Anglais (eng) Français (fre) Mots-clés : Fauteuil roulant  Test respiratoire  Cardiorespiratory fitness,Manual wheelchair users,Propulsion,Rehabilitation,Treadmill Résumé : Background: Cardiorespiratory fitness assessment and training among manual wheelchair (MW) users are predominantly done with an arm-crank ergometer. However, arm-crank ergometer biomechanics differ substantially from MW propulsion biomechanics. This study aimed to quantify cardiorespiratory responses resulting from speed and slope increments during MW propulsion on a motorized treadmill and to calculate a predictive equation based on speed and slope for estimating peak oxygen uptake (VO2peak ) in MW users. Methods: In total, 17 long-term MW users completed 12 MW propulsion periods (PP), each lasting 2min, on a motorized treadmill, in a random order. Each PP was separated by a 2-min rest. PPs were characterized by a combination of 3 speeds (0.6, 0.8 and 1.0m/s) and 4 slopes (0°, 2.7°, 3.6° and 4.8°). Six key cardiorespiratory outcome measures (VO2 , heart rate, respiratory rate, minute ventilation and tidal volume) were recorded by using a gas-exchange analysis system. Rate of perceived exertion (RPE) was measured by using the modified 10-point Borg scale after each PP. Results: For the 14 participants who completed the test, cardiorespiratory responses increased in response to speed and/or slope increments, except those recorded between the 3.6o and 4.8o slope, for which most outcome measures were comparable. The RPE was positively associated with cardiorespiratory response (r s ≥0.85). A VO2 predictive equation (R 2=99.7%) based on speed and slope for each PP was computed. This equation informed the development of a future testing protocol to linearly increase VO2 via 1-min stages during treadmill MW propulsion. Conclusions: Increasing speed and slope while propelling a MW on a motorized treadmill increases cardiorespiratory response along with RPE. RPE can be used to easily and accurately monitor cardiorespiratory responses during MW exercise. The VO2 can be predicted to some extent by speed and slope during MW propulsion. A testing protocol is proposed to assess cardiorespiratory fitness during motorized MW propulsion.

The effect of two lumbar belt designs on trunk repositioning sense in people with and without low back pain / Jean-Alexandre Boucher in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 306-311 Titre : The effect of two lumbar belt designs on trunk repositioning sense in people with and without low back pain Type de document : texte imprimé Auteurs : Jean-Alexandre Boucher, Auteur ; Richard Preuss, Auteur ; Nicolas Roy, Auteur Année de publication : 2017 Article en page(s) : p. 306-311 Langues : Anglais (eng) Français (fre) Mots-clés : Lombalgie  Proprioception,Trunk repositioning sense,Repositioning error,Low back pain,Lumbar belt Résumé : Objectives: Low back pain (LBP) has previously been associated with impaired lumbar proprioception, which may lead to and/or perpetuate joint instability as a cause of LBP. Wearing a lumbar belt (LB) may be beneficial in this regard. The primary aim was to determine the effect of 2 LB designs (extensible and non-extensible) on trunk repositioning sense in people with and without LBP. A secondary aim was to evaluate whether patients showing different clinical signs of lumbar instability differentially benefit from LBs in terms of lumbar proprioception. Design: Within-group experimental study with a healthy control group. Methods: In total, 38 patients with LBP and 19 healthy controls participated in this study. Lumbar proprioception (position sense) was measured with participants sitting in a device that allowed for generating movements in axial rotation. Three experimental conditions were compared: (1) no LB, (2) extensible LB, (3) non-extensible LB. Four repositioning errors were computed for each experimental condition: constant error (CE), absolute error (AE), variable error (VE) and total variability (E). Results: CE and AE scores were higher for LBP patients than healthy controls (all P <0.001), but scores did not significantly differ by condition. Additional subgroup analyses of clinical signs of instability were inconclusive, showing the same results in LBP patients with low and high instability scores (all P <0.001). Conclusions: This study confirms a significant loss of proprioception in trunk axial rotation in patients with LBP. Wearing an LB did not improve proprioception, but the contact between the LB and the skin might depend on the movement direction. Future studies should investigate the 3 planes of motion while eliminating the effect of the vestibular system.

Transcranial direct current stimulation over multiple days enhances motor performance of a grip task / Julie Fan in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 329-333 Titre : Transcranial direct current stimulation over multiple days enhances motor performance of a grip task Type de document : texte imprimé Auteurs : Julie Fan, Auteur ; Marie-Hélène Milot, Auteur ; Julien Voisin, Auteur Année de publication : 2017 Article en page(s) : p. 329-333 Langues : Anglais (eng) Français (fre) Mots-clés : Performance  Stimulation  Cerveau  Motor performance,Neurostimulation,Primary motor cortex,Grip control,Neurorehabilitation Résumé : Background: Recovery of handgrip is critical after stroke since it is positively related to upper limb function. To boost motor recovery, transcranial direct current stimulation (tDCS) is a promising, non-invasive brain stimulation technique for the rehabilitation of persons with stroke. When applied over the primary motor cortex (M1), tDCS has been shown to modulate neural processes involved in motor learning. However, no studies have looked at the impact of tDCS on the learning of a grip task in both stroke and healthy individuals. Objective: To assess the use of tDCS over multiple days to promote motor learning of a grip task using a learning paradigm involving a speed-accuracy tradeoff in healthy individuals. Methods: In a double-blinded experiment, 30 right-handed subjects (mean age: 22.1+3.3 years) participated in the study and were randomly assigned to an anodal (n =15) or sham (n =15) stimulation group. First, subjects performed the grip task with their dominant hand while following the pace of a metronome. Afterwards, subjects trained on the task, at their own pace, over 5 consecutive days while receiving sham or anodal tDCS over M1. After training, subjects performed de novo the metronome-assisted task. The change in performance between the pre and post metronome-assisted task was used to assess the impact of the grip task and tDCS on learning. Results: Anodal tDCS over M1 had a significant effect on the speed-accuracy tradeoff function. The anodal tDCS group showed significantly greater improvement in performance (39.28+15.92%) than the sham tDCS group (24.06+16.35%) on the metronome-assisted task, t (28)=2.583, P =0.015 (effect size d =0.94).

To boost motor recovery, transcranial direct current stimulation (tDCS) is a promising, non-invasive brain stimulation technique for the rehabilitation of persons with stroke. When applied over the primary motor cortex (M1), tDCS has been shown to modulate neural processes involved in motor learning. However, no studies have looked at the impact of tDCS on the learning of a grip task in both stroke and healthy individuals. Objective: To assess the use of tDCS over multiple days to promote motor learning of a grip task using a learning paradigm involving a speed-accuracy tradeoff in healthy individuals. Methods: In a double-blinded experiment, 30 right-handed subjects (mean age: 22.1+3.3 years) participated in the study and were randomly assigned to an anodal (n =15) or sham (n =15) stimulation group. First, subjects performed the grip task with their dominant hand while following the pace of a metronome. Afterwards, subjects trained on the task, at their own pace, over 5 consecutive days while receiving sham or anodal tDCS over M1. After training, subjects performed de novo the metronome-assisted task. The change in performance between the pre and post metronome-assisted task was used to assess the impact of the grip task and tDCS on learning. Results: Anodal tDCS over M1 had a significant effect on the speed-accuracy tradeoff function. The anodal tDCS group showed significantly greater improvement in performance (39.28+15.92%) than the sham tDCS group (24.06+16.35%) on the metronome-assisted task, t (28)=2.583, P =0.015 (effect size d =0.94). Conclusions: Anodal tDCS is effective in promoting grip motor learning in healthy individuals. Further studies are warranted to test its potential use for the rehabilitation of fine motor skills in stroke patients. Permalink : ./index.php?lvl=notice_display&id=51697

Variable compensation during the sit-to-stand task among individuals with severe knee osteoarthritis / Yoshimasa Sagawa in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 312-318 Titre : Variable compensation during the sit-to-stand task among individuals with severe knee osteoarthritis Type de document : texte imprimé Auteurs : Yoshimasa Sagawa, Auteur ; Stéphane Armand, Auteur ; Alice BONNEFOY-MAZURE, Auteur Année de publication : 2017 Article en page(s) : p. 312-318 Langues : Anglais (eng) Français (fre) Mots-clés : Arthrose  Genou  Analyse  Knee osteoarthritis,Motion analysis,Clinical variables,Biomechanics Résumé : Background: Individuals with knee osteoarthritis (OA) show variability during the sit-to-stand (STS) task, so they may not perform the STS in the same way. This study aimed to determine whether individuals with knee OA have different strategies in performing the STS. Methods: Participants with knee OA and able-bodied individuals underwent STS evaluation at a self-selected pace with use of a motion measurement system consisting of 12 cameras and 2 force plates. Results: In total, 101 participants (57 women) with knee OA showed 3 main STS strategies. As compared with the 27 controls (14 women), 24 OA participants, compensated STS, showed greater trunk flexion (47.1° vs. 38.3°; P <0.01) and trunk obliquity (4.6° vs. –0.8°; P <0.001) when completing the STS task in the same amount of time as controls (2.4 vs. 2.7s; P =0.999). The second group (n =59), inadequately compensated STS, also compensated with trunk flexion (47.7° vs. 38.3°; P <0.01) and trunk obliquity (1.6° vs. –0.8°; P <0.001) but took longer than controls (3.4 vs. 2.7s; P =0.001). The third group (n =18), severe impaired STS, took an extended amount of time to execute the STS (6s), with marked trunk flexion (59.2°) and obliquity (4.1°), so participants in this group were perhaps severely impaired in completing the STS. Conclusion: This study identified 3 groups STS trunk strategies among participants with STS. Moreover, the data reveal a concise representation of the relations among strategy variables. The findings could be used to simplify the characterization of the STS among patients with knee OA and aid with follow-up.

Type de document : texte imprimé Auteurs : Mikolaj Przydacz, Auteur ; Jacques Corcos, Auteur ; Pierre Denys, Auteur Année de publication : 2017 Article en page(s) : p. 341-346 Langues : Anglais (eng) Français (fre) Mots-clés : Pays voie développement  Pays développé  Neurogenic bladder,Prevalence,Management,Developing countries,Under-developed countries,Emerging regions Résumé : Objective: To summarize information on Neurogenic Bladder (NB) epidemiology, management and access to patient treatment in developing countries and emerging regions of the world in order to propose future interventions and help governmental as well as non-governmental organizations design their action plans. Methods: Different search methods were used to gather the maximum available data. They included strategic searches; reference checks; grey literature searches (reports, working papers, government documents, civil society information); contacting professional societies, registries, and authors; requesting unpublished data from organizations; and browsing related websites and journals. Results: The incidence and prevalence rates of NB in developing countries are difficult to establish because epidemiological reports are few and far between. The frequency of bladder dysfunction in neurologically impaired populations can be approximately estimated in some of these countries. Similar information paucity affects diagnostic and therapeutic approaches to NB patients living in less-developed regions of the world. The assessment and management of NB seems to vary markedly between countries, and care of patients from emerging regions of the world is often inadequate. Conclusion: Strong concerted efforts are needed on the part of international scientific societies, non-governmental organizations and local governments to work together to change the prognosis for these patients and to improve their quality of life.

Workers’ perspectives on return to work after total knee arthroplasty / Pascale Maillette in Annals of physical and rehabilitation medicine, Vol. 60, n° 5 (September 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 5 (September 2017) . - p. 299-305 Titre : Workers’ perspectives on return to work after total knee arthroplasty Type de document : texte imprimé Auteurs : Pascale Maillette, Auteur ; Nathaly Gaudreault, Auteur ; Marie-France Coutu, Auteur Année de publication : 2017 Article en page(s) : p. 299-305 Langues : Anglais (eng) Français (fre) Mots-clés : Genou  Prothèse  Rééducation fonctionnelle  Total knee arthroplasty,Rehabilitation,Biopsychosocial,Representations,Work disability Résumé : Objectives: Total knee arthroplasty is an effective intervention for people with osteoarthritis. However, 15 to 30% of patients do not return to work, and studies frequently fail to provide an explanation of what may lead to work disability from workers’ perspectives of the biopsychosocial factors. This study aimed to document workers’ representations or understanding of work disability after total knee arthroplasty. Method: We adopted a qualitative approach with a narrative inquiry method. A convenience sample of partially and fully disabled workers was interviewed 6 to 12months after surgery with use of a semi-structured interview guide and questionnaires on physical work demands and pain. Interviews were audiotaped, transcribed verbatim, and anonymized. Consensus was reached on coding, and multidisciplinary content analysis was performed. Results: Among the 8 workers interviewed, all were formally employed before surgery, half were men, and the mean age was 55years. Half were not back at work when interviewed and felt they had received little support from their workplace, were struggling to adapt to their new condition, and had very few adaptive strategies for trying to get better (other than waiting), which did not make sense to them. By contrast, the other half felt they had experienced greater improvement after surgery and received concrete support from their workplace, which facilitated their return to work in their view. Conclusion: A work disability paradigm, based on a biopsychosocial approach, should be considered in rehabilitation when workers experience difficulty returning to work after total knee arthroplasty, because other factors besides the patient's condition may be involved.
