Introduction: Action Observation (AO) is a multisensory approach encompassing motor, somatosensory and cognitive rehabilitation. Several Studies have proved the effects of action observation on recovery of motor functions in chronic stroke survivors. However, the effect of action observation strategy on acute stroke participants remains unclear. The objective of this study was to find out the effectiveness of action observation to improve upper limb function in acute stroke. Methods: 28 acute stoke participants were selected based on inclusion and exclusion criteria and randomly assigned into two groups based on computer generated randomization. Action observation training group (AO) received action observation training and conventional group received conventional physiotherapy. Both the groups received 45 minutes session per day for the total duration of 10 days. Results: Upper limb functions were measured using Fugl Myer upper limb component (FMA) and action research arm test (ARAT)at the baseline and after the intervention. Compared with the conventional training group, AO group showed significant improvement in ARAT but no significant difference between the groups in FMA. Conclusion: In conclusion Action observation treatment may become a useful strategy in rehabilitation of acute stroke participants.

Observation Training

BACKGROUND & PURPOSE: The most common disabling motor decit following stroke is the loss of upper limb function. 5-20% of patients presenting an upper limb paralysis at onset may improve the motor impairment overtime. Action observation training is a novel rehabilitation approach exploiting this mirror mechanism and its potential role in motor learning for motor recovery. Aim of this study was to examine the effects of action observation therapy on upper limb functions in acute stroke patients. METHODOLOGY: Stroke survivors (N= 50) were consecutively recruited 22 days (±5) after a rst-ever stroke and participants watched video footage of daily routine tasks (actions). Each action based on some relevant ADLs motor sequence display in order of ascending difculty and lasting for 3 minutes and therapist prompted the patient to perform the same movement for 2 minutes. At the end of each sequence, patients were given conventional physiotherapy and AOT 1 hour daily for 5 days/week for 4 weeks. RESULTS: Upper Limb part of FMA, Modied Ashworth Scale scores & nine-hole peg test were taken at baseline and after 4 weeks as outcome measure. Paired 't' test and Wilcoxon's signed-rank has been used for analysis of Fugl Meyer scale, Modied Ashwarth Scale and Nine-hole peg pre and post treatment scores respectively (p value<0.05) So, a statistically signicant difference was found after treatment for all variables. CONCLUSION: The nding of this study is suggesting that Action observation training programs contribute to improve motor recovery in acute stroke patients.

Observation Training

Background: Hand motor deficits contribute to multiple sclerosis (MS)-related disability. Action observation training (AOT) is promising to improve upper limb function in neurologic patients. Objectives: In this preliminary study, we investigated AOT effects on dominant-hand motor performance in MS patients with upper limb motor impairment and performed an explorative analysis of their anatomical and functional magnetic resonance imaging (MRI) substrates. Methods: In total, 46 healthy controls (HC) and 41 MS patients with dominant-hand motor impairment were randomized to AOT (HC-AOT = 23; MS-AOT = 20; watching daily-life action videos and execution) or control-training (HC-Control = 23; MS-Control = 21; watching landscapes videos and execution). Behavioral, structural, and functional (at rest and during object manipulation) MRI scans were acquired before and after a 2-week training. Results: After training, MS groups improved in right upper limb functions, mainly in AOT group ( p from 0.02 to 0.0001). All groups showed regional increased and decreased gray matter volume, with specific AOT effects in fronto-temporal areas in MS-AOT ( p < 0.001), without white matter (WM) integrity modifications. Increased and reduced recruitments of the action observation matching system and its connections in MS-AOT were found ( p < 0.001). Motor improvements were correlated with volumetric and functional MRI modifications ( r from −0.78 to 0.77, p < 0.001). Conclusion: The 10-day AOT promotes clinical improvements in MS patients through structural and functional modifications of the action observation matching system.

Observation Training

This study evaluated the effect of action observation training on spasticity, gross motor function, and balance in children with spastic diplegia cerebral palsy. Eighteen children with cerebral palsy participated in this study. The participants were randomized into the action observation training group (n = 9) and a control group (n = 9). The action observation training group repeatedly practiced the action with their motor skills, while the control group practiced conventional physical therapy. Both groups received 30 min sessions, 3 days a week, for 6 weeks. To confirm the effects of intervention, the spasticity, gross motor function measurement (GMFM), and pediatric reaching test (PRT) were evaluated. The results showed that in the plantar flexor contracture test of both sides, the Modified Tardieu Scale (MTS) of the right side of knee joints, GMFM-B, C, and D were significantly increased between pre- and post-intervention within both groups (p < 0.05). PRT was significantly increased between pre- and post-intervention within the both groups (p < 0.05), and there was a significant difference between the two groups (p < 0.05). These results suggest that action observation training is both feasible and beneficial for improving spasticity, gross motor function, and balance in children with spastic diplegia cerebral palsy.

The aim of the present study was to assess the role of action observation treatment (AOT) in the rehabilitation of upper limb motor functions in children with cerebral palsy. We carried out a two-group, parallel randomized controlled trial. Eighteen children (aged 5–11 yr) entered the study: 11 were treated children, and 7 served as controls. Outcome measures were scores on two functional scales: Melbourne Assessment of Unilateral Upper Limb Function Scale (MUUL) and the Assisting Hand Assessment (AHA). We collected functional scores before treatment (T1), at the end of treatment (T2), and at two months of follow-up (T3). As compared to controls, treated children improved significantly in both scales at T2 and this improvement persisted at T3. AOT has therefore the potential to become a routine rehabilitation practice in children with CP. Twelve out of 18 enrolled children also underwent a functional magnetic resonance study at T1 and T2. As compared to controls, at T2, treated children showed stronger activation in a parieto-premotor circuit for hand-object interactions. These findings support the notion that AOT contributes to reorganize brain circuits subserving the impaired function rather than activating supplementary or vicariating ones.
