“…Patients (age range 24-91) were classi ed into three age groups: ≤44 years (adult), 45-63 years (middle aged), and ≥ 64 years (aged) based on the Medline MeSH classi cation of age categories (47). A cut-off at 64 years was set due to the ndings of Mulder, Hochstenbach (27).…”

BackgroundMotor imagery (MI) has been successfully applied in neurological rehabilitation. Little is known about the spontaneous selection of the MI perspectives in patients with sensorimotor impairments. What MI perspective is selected: internal (first- person view), or external (third-person view)? The aim was to evaluate the MI perspective preference in patients after stroke (STR), with Multiple Sclerosis (MS) or Parkinson’s disease (PD).MethodsIn a longitudinal study including four measurement sessions over two weeks, MI ability and MI perspective preference in both visual and kinaesthetic imagery modalities were assessed using the Kinaesthetic and Visual Imagery Questionnaire including 20 items (KVIQ-20), mental rotation, and mental chronometry. Additionally, patients' activity level was assessed. Descriptive statistical analyses were performed regarding different age- (≤44, 45-63, 64≤) and activity levels (inactive, partially active, active), and KVIQ-20 movement classifications (axial, proximal, distal, upper and lower limb).ResultsIn total, 55 in- and outpatients (25 SRT, 25 MS, 5 PD; 25 females; mean age 58±14 years) were included. At the first measurement session, the mean mental rotation score was 27±4.1 out of 32. For mental chronometry, a congruency ratio of 1.0±0.3 was determined. The KVIQ-20 scores for the visual and kinaesthetic subscales were 62.4±16.2 and 58.2±17.2. The internal MI perspective was favoured in 66.5% on the visual subscale and in 72.7% on the kinaesthetic subscale. The external perspective was preferred in 30.3% on the visual subscale and in 26.5% on the kinaesthetic subscale. Over the four measurement sessions, patients became more consistent in their MI perspective selection. MI perspective changes occurred mainly during imagination of shoulder, arm and neck movements. During imagination of foot and finger movements their MI perspective was more constant. Results showed a tendency to use an external perspective in patients older than 64 years and in patients with a descreasing physical activity level. Axial and proximal movements were commonly imagined using the external perspective. ConclusionIt is recommended to evaluate the spontaneous MI perspective selection to design patient-specific MI training interventions. Distal movements (foot, finger) may be an indicator when evaluating the consistency of the MI perspective in patients with sensorimotor impairments.

“…As for healthy subjects (HS), most investigations on MI of people with neurological diseases have mainly examined upper limb movements with different motor tasks such as sequential pressing of buttons 18 , finger-to-thumb opposition 19 , pointing towards targets 15 , 20 , hand manipulation 17 , 21 , hand grasping and arm-lifting 22 , and bimanual circle-line coordination 23 . However, examples of MI involving lower limb are also present 24 – 30 .…”

Motor imagery (MI) is the mental simulation of an action without any overt motor execution. Interestingly, a temporal coupling between durations of real and imagined movements, i.e., the so-called isochrony principle, has been demonstrated in healthy adults. On the contrary, anisochrony has frequently been reported in elderly subjects or those with neurological disease such as Parkinson disease or multiple sclerosis (MS). Here, we tested whether people with MS (PwMS) may have impaired MI when they imagined themselves walking on paths with different widths. When required to mentally simulate a walking movement along a constrained pathway, PwMS tended to overestimate mental movement duration with respect to actual movement duration. Interestingly, in line with previous evidence, cognitive fatigue was found to play a role in the MI of PwMS. These results suggest that investigating the relationship between cognitive fatigue and MI performances could be key to shedding new light on the motor representation of PwMS and providing critical insights into effective and tailored rehabilitative treatments.

“…It measures the temporal congruency between imagining and executing a movement. In the present study, patients performed a grasping and drinking movement with a plastic cup [ 49 ]. The examiner demonstrated the task once and the patient was then allowed to practice the task physically and mentally until the examiner could confirm that the patient was able to comply and understood the procedure.…”

Background Motor imagery (MI) has been successfully applied in neurological rehabilitation. Little is known about the spontaneous selection of the MI perspectives in patients with sensorimotor impairments. What perspective is selected: internal (first-person view), or external (third-person view)? The aim was to evaluate the MI perspective preference in patients with sensorimotor impairments. Methods In a longitudinal study including four measurement sessions, 55 patients (25 stroke, 25 multiple sclerosis, 5 Parkinson’s disease; 25 females; mean age 58 ± 14 years) were included. MI ability and perspective preference in both visual and kinaesthetic imagery modalities were assessed using the Kinaesthetic and Visual Imagery Questionnaire-20 (KVIQ-20), the body rotation task (BRT), and mental chronometry (MC). Additionally, patients’ activity level was assessed. Descriptive analyses were performed regarding different age- (< 45, 45–64, > 64), activity levels (inactive, partially active, active), and KVIQ-20 movement classifications (axial, proximal, distal, upper and lower limb). A mixed-effects model was used to investiage the relationship between the primary outcome (MI perspective: internal, external) with the explanatory variables age, MI modality (visual, kinaesthetic), movement type (axial, proximal, distal), activity levels and the different assessments (KVIQ-20, BRT, MC). Results Imagery modality was not a significant predictor of perspective preference. Over the four measurement sessions, patients tended to become more consistent in their perspective selection, however, time point was not a significant predictor. Movement type was a significant predictor: imagination of distal vs. axial and proximal vs. axial movements were both associated with preference for external perspective. Patients with increased physical activity level tend to use internal imagery, however, this effect was borderline not statistically significant. Age was neither a significant precictor. Regarding the MI assessments, the KVIQ- 20 score was a significant predictor. The patients with higher test scores tend to use the external perspective. Conclusion It is recommended to evaluate the spontaneous MI perspective selection to design patient-specific MI training interventions. Distal movements (foot, finger) may be an indicator when evaluating the consistency of the MI perspective in patients with sensorimotor impairments.
