Effects of motor imagery on strength, range of motion, physical function, and pain intensity in patients with total knee arthroplasty: A systematic r…
2021
Abstract Background In the early stages of total knee arthroplasty (TKA) rehabilitation, in which physical function in general can be affected, motor imagery (MI) might play a relevant role. Objective To assess the impact of MI on strength, active range of motion (ROM), pain intensity, and physical function in patients with TKA. Methods We conducted a systematic review and meta-analysis of randomised controlled trials. Pooled effects were calculated as standardised mean differences (SMDs) and 95% confidence intervals (CIs) for the relevant outcomes using random effects model. The certainty of evidence was assessed with GRADE approach. Results This review included 7 articles. The addition of…
Effects of Adding Motor Imagery to Early Physical Therapy in Patients with Knee Osteoarthritis who Had Received Total Knee Arthroplasty
2020
Abstract Objective To investigate the effects of the inclusion of motor imagery (MI) principles into early physical therapy on pain, disability, pressure pain thresholds (PPTs), and range of motion in the early postsurgical phase after total knee arthroplasty (TKA). Methods A randomized clinical trial including patients with knee osteoarthritis who have received TKA was conducted. Participants were randomized to receive five treatment sessions of either physical therapy with or without MI principles in an early postsurgical phase after a TKA (five days after surgery). Pain intensity (visual analog scale [VAS], 0–100), pain-related disability (short-form Western Ontario McMaster Universities…
MindBEAGLE — A new system for the assessment and communication with patients with disorders of consciousness and complete locked-in syndrom
2017
Patients with disorders of consciousness (DOC) cannot reply to questions or clinical assessments using voluntary motor control, and therefore it is very difficult to assess their cognitive capabilities and conscious awareness. Patients who are locked-in (LIS) are instead fully conscious, and they can communicate with their preserved eye movements. However, when the residual oculomotor activity is also lost (e.g., patients with amyotrophic lateral sclerosis disease of very long duration), the locked-in status becomes complete (CLIS). In CLIS patients, detection of conscious awareness may become very challenging, similarly to the subjects with DOC. mindBEAGLE has a physiological testing batte…
Motor imagery and cortico-spinal excitability: A review
2016
International audience; Motor imagery (MI) has received a lot of interest during the last decades as its chronic or acute use has demonstrated several effects on improving sport performances or skills. The development of neuroimagery techniques also helped further our understanding of the neural correlates underlying MI. While some authors showed that MI, motor execution and action observation activated similar motor cortical regions, transcranial magnetic stimulation (TMS) studies brought great insights on the role of the primary motor cortex and on the activation of the cortico-spinal pathway during MI. After defining MI and describing the TMS technique, a short report of MI activities on…
Pragmatics, Metaphor Studies and the Challenge of Mental Imagery
2023
Metaphor is considered a figurative use of language, a term that seems to recall the imagistic dimension characterizing this kind of utterances. Tzvetan Todorov (1967) speaks of “figure” as “visibility of speech”: as a figure, metaphor provides a kind of figurability to what is communicated. As Paul Ricoeur wrote in La métaphore vive (Ricoeur, 1975), metaphor makes “speech appear”. Precisely because of the reliance on the idea of figure, it is therefore not surprising that discussions on metaphor often refer to the role that mental images play in their comprehension. A long tradition holds that the formation of a mental image is fundamental for the comprehension of certain kinds of metaphor…
Improving Hand Hygiene Behavior Using a Novel Theory-Based Intervention During the COVID-19 Pandemic
2022
Abstract Background Promoting the adoption of personal hygiene behaviors known to reduce the transmission of COVID-19, such as avoiding touching one’s face with unwashed hands, is important for limiting the spread of infections. Purpose We aimed to test the efficacy of a theory-based intervention to promote the avoidance of touching one’s face with unwashed hands to reduce the spread of COVID-19. Methods We tested effects of an intervention employing imagery, persuasive communication, and planning techniques in two pre-registered studies adopting randomized controlled designs in samples of Australian (N = 254; Study 1) and US (N = 245; Study 2) residents. Participants were randomly assigned…
Pleasant Musical Imagery : Eliciting Cherished Music in the Second Person
2019
This article introduces the notion of pleasant musical imagery (PMI) for denoting everyday phenomena where people want to cherish music ‘‘in their heads.’’ This account differs from current paradigms for studying musical imagery in that it is not based a priori on (in)voluntariness of the experience. An empirical investigation of the structure and experiential content in 50 persons’ experiences of PMI applied the elicitation interview method. Peer judgments of the interviews helped to bridge a phenomenological investigation of particular experiences with systematic between-subjects analysis. Both structural features of the imagery (e.g., Looseness of structure or Looping) and content featur…
Imagery ability and imagery use in individual and team sports
2014
The purpose of this research was to examine whether individual and team sport athletes differ in their imagery use and imagery ability, and to examine whether level of sport participation or weekly sport involvement are variables that differentiate between athletes on the basis of their levels of imagery ability and imagery use. Two measures were conducted. The Sport Imagery Ability Measure (SIAM) is a 48-item self-report measure that uses four sport related scenes to examine the dimensional, sensorial, and emotional characteristics of generating images. The Sport Imagery Questionnaire (SIQ) is a 30-item self-report measure that examines five characteristics associated with the cognitive an…
Left Prefrontal Cortex Contributes to Motor Imagery: A Pilot Study
2013
Transcranial magnetic stimulation (TMS) over the motor cortex during motor imagery results in increased amplitudes of motor evoked potentials (MEPs) in muscles specific to the imagined movement. Functional MRI studies demonstrate that motor imagery involves a widespread neural network including prefrontal and parietal areas. The purpose of this pilot TMS study was to explore whether the left prefrontal cortex (PFC) is an active part of the motor imagery network. MEPs were recorded in 5 healthy subjects in tibialis anterior (TA) muscles during the imagined right ankle dorsiflexion while the neural processes in the left PFC were disturbed by a single TMS pulse 300ms prior to the leg area stim…
Successful approaches to mental practice : A case study of four pianists
2019
Musicians often use mental practice for enhancing performance, but individuals may have different preferences and skills in their characteristic, individually successful ways of carrying out such practice. In this study, we focus on the approaches to mental practice of four pianists who, according to the ratings of a panel of expert judges, showed outstanding improvement in their performances following their mental practice of a new piece in at least one of the two conditions: silent reading of the score or reading the score while simultaneously listening to the music. The four pianists’ approaches to mental practice were studied through self-reports in post-task interviews that were compar…
