Abstract Upper limb hemiparesis is a common impairment following stroke and can affect interjoint coordination. Motor imagery training is one treatment strategy. However, motor imagery can use visual or kinesthetic modalities and there has been a lack of research comparing the effectiveness of these modalities when treating the upper limb. The aim of this study was to compare visual and kinesthetic motor imagery in improving interjoint coordination in the hemiparetic index finger. Fifteen stroke survivors with upper limb hemiparesis were allocated to groups using kinesthetic or visual motor imagery, or a control group using guided relaxation. Reaching and grasping movements of the upper limb were captured using optoelectronic motion capture. Interjoint coordination of the hemiparetic index finger was analysed using the index of temporal coordination. No significant differences were found for interjoint coordination following treatment in either condition. Future work should focus on comparing kinesthetic and visual motor imagery in the rehabilitation of more proximal upper limb joints.

Background:Elbow fracture is treated either conservatively or surgically followed by a period of immobilization with casting or splinting. A splint used to immobilize upper limbs for many weeks results in changes in both the peripheral musculature and the central nervous system. It is well known that common complaints after upper limb fractures include weakness, pain, and stiffness; therefore, pain management is important in the early stages of the rehabilitation of upper limb fractures.Objectives:This pilot study aimed to investigate the efficacy of graded motor imaginary (GMI) on pain, range of motion (ROM), and function in patients with posttraumatic stiff elbow.Methods:Fourteen patients with posttraumatic stiff elbow (6 women, mean age: 45.42 ± 11.26 years, mean body mass index: 24.29 ± 3.38 kg\m2and mean duration of immobilization: 4.75 ± 1.03 weeks) were randomly allocated to either GMI or control groups. The GMI group received GMI treatment in addition to a structured exercise program, and the control group received a structured exercise program (two days per week for six weeks) (Figure 1). The assessments included pain at rest and during activity using the visual analog scale (VAS), elbow active ROM with a digital goniometer (Baseline Evaluation Instrument, Fabrication Enterprises, Inc., White Plains, NY), and upper extremity functional status using the Disability of the Arm, Shoulder and Hand Questionnaire (DASH). The assessments were performed at baseline and after the 6-week intervention.Figure 1.Graded motor imagery performed with mirror boxResults:After the 6-week intervention, there was a significant increase in elbow flexion-extension ROM and supination-pronation ROM, and improvement in DASH score in both groups (p<0.05). However, improvement in VAS-rest and VAS-activity was significantly higher in the GMI group than the control group (p=0.03 and p=0.01, respectively).Conclusion:A conservative treatment program consisting of GMI treatment in addition to a structured exercise program applied twice a week for 6 weeks, has been found more effective in decreasing pain in the posttraumatic stiff elbow. It could be concluded that GMI is an effective treatment method for elbow fracture in patients with predominant elbow pain.References:[1] Harris JE, Hebert A.

Abstract Background: Gait disorders in individuals with Parkinson’s Disease (PD) may be associated with alterations in the motor control system and aggravated by psychoemotional and cognitive issues. Therapeutic strategies aimed at self-perception and motor regulation seem to be promising. Motor imagery (MI) has been shown to be one of these strategies, but there is still no clear evidence of its applicability in this population. The aim of this trial is to determine the effects of motor imagery training on the gait and electroencephalographic activity of individuals with PD. Methods: The sample consisted of 40 individuals, aged between 45 and 75 years, in the mild and moderate phase of the disease, with the ability to generate voluntary mental images. They will be assessed for cognitive level, degree of physical disability, mental image clarity, kinematic gait variables, electroencephalographic activity and mobility. Next, subjects will be randomly assigned to an experimental (EG) and control group (CG). The EG will perform motor imagery and gait, while the CG will only engage in gait exercises. Twelve training sessions will be conducted lasting up to 90 minutes each, 3 times a week, for 4 weeks. They will be reassessed on the kinematic variables of gait, electroencephalographic activity and mobility, one, seven and thirty days after the final training session. Discussion: The results may provide an important advance in neurological rehabilitation. An easy-access and low-cost intervention may help improve gait, electroencephalographic activity and mobility in individuals with PD. Trial Registration: Clinicaltrials.gov: NCT03439800.

The objective of the present study is to analyze the effects of motor mental imagery training on tennis service performance among tennis athletes who fast during Ramadan. Participants were 38 young male tennis players, randomly divided into two groups: Imaging Training (IMG, n = 18) and control group (CG, n = 20). The CG has watched videos on the history of the Olympic Games, while IMG has followed a training program in motor imagery. The performance of the tennis service was obtained by the product between accuracy and speed of typing (accuracy × average speed of all shots (km/h)). The effect of group/time interaction (p < 0.01) was identified for all performance indicators (accuracy, running speed and performance (speed × precision)), with improvement only in IMG (p = 0.01). The results showed that motor imagery training could be an effective strategy for mitigating/counteracting the negative effects of Ramadan on the tennis service performance.

Objective: The purpose of this study was to measure the impact of the motor-cognitive remediation program (MCRP) that uses sensorimotor and visual-motor imagery techniques on attentional functions in preschoolers with ADHD symptoms. Method: A total of 15 high-risk preschoolers were selected based on high ADHD symptoms. An experimental group participated in the MCRP and was compared with a control group. The MCRP consisted of 30 activities, 3 times a week, during 12 weeks. Results: Children in the experimental group improved significantly for orienting (selective attention) and executive control (inhibition, stopping, and engaging mental operations) compared with the control group. Conclusion: These results are a first step to support the postulate that training specific attentional functions by sensorimotor activities and visual-motor imagery has an impact on the cognitive network of attention. This study suggests the potential value of MCRP addressed to preschoolers with ADHD symptoms.

Recently, motor imagery training combined with electromyography-triggered electrical stimulation (MIT EMG-ES) has been reported as a remedial treatment for stroke patients. However, the clinical evidence of the effect is still lacking. To investigate the effect of MIT EMG-ES on lower extremities and activities of daily of living (ADL) in patients with stroke, the participants were randomly assigned to an experimental group ([Formula: see text]) or control group ([Formula: see text]). The experimental group underwent MIT EMG-ES, whereas the control group performed underwent motor imagery training. In addition, both groups received the same conventional rehabilitation therapy. All participants underwent treatment for 30[Formula: see text]min a day, 5 sessions per week, for 4 weeks. Lower extremities function was measured by the Fugl–Meyer Assessment Lower Extremity (FMA-LE), Timed Up-and-Go (TUG) test and 10 m Walk (10[Formula: see text]MW) test. ADL were measured by the Korea version of the Modified Barthel Index (K-MBI). The experimental group except for the FMA-LE group showed more improvement in TUG and 10[Formula: see text]MW test scores than the control group ([Formula: see text]). The effect size showed FMA-LE, TUG, and 10[Formula: see text]MW test (0.7, 1.0, 0.7, respectively). However, there was no statistically significant difference between the two groups in K-MBI ([Formula: see text]). Our findings suggest that MIT EMG-ES may be a novel treatment for lower extremities function in patients with stroke better than MIT alone.
