Effects of Action Observation Therapy Based on Virtual Reality for Upper Extremity Rehabilitation in Stroke
Riphah International University
36 participants
Nov 25, 2023
INTERVENTIONAL
Conditions
Summary
This study aims to conduct a randomized controlled trial (RCT) assessing the effectiveness of combining Action Observation (AO) with Virtual Reality (VR) in improving upper limb function for stroke patients compared to AO therapy alone. Individuals who meet the inclusion criteria will be assigned by lottery into one of two groups: Group A will receive only AO therapy, watching daily actions and then executing them, while Group B will receive both AO and VR therapy, using VR glasses to complete tasks. The Box and Block Test for manual dexterity, the Timed Test, the Modified Ashworth Scale for spasticity, the Rankin Scale for symptom severity, and the Fugl-Meyer Assessment for motor, balance, sensation, and joint function will all be used in the evaluation, both before and after the intervention. Every participant will go through 18 sessions totaling 60
Eligibility
Inclusion Criteria6
- • Both Male \& Female
- years of age
- Primarily motor symptoms with unilateral upper limb paresis (controlled via standard neurological examination)
- Residual movement ability of the paretic upper limb, controlled by Medical Research Council (MRC) index (\> 2 and \< 4), active use of the hemiplegic limb, from minimal (mainly for assistance tasks to the preserved limb) to discrete (characterized by coarse manipulation and an inability to perform precision grip)
- mini-mental state examination (MME) score ≥27
- Sufficient cooperation and cognitive understanding to participate to the activities, controlled by the investigator recruiting the patient
Exclusion Criteria8
- • Presence of severe cognitive impairment (score \< 20 at Mini Mental State Examination \[MMSE\])
- Presence of severe forms of unilateral spatial neglect, controlled using the Bells Test (cut-off = / \> 50%)
- Presence of severe ideomotor Apraxia
- Presence of severe anosognosia, assessed by clinical examination
- Presence of severe language comprehension deficits, assessed by clinical examination.
- Presence of severe untreated psychiatric disorders
- Sensory impairments hindering participation and/or not compensated visual deficits of central origin
- Drug-resistant epilepsy

Interventions
During each training session, participants were asked to observe a specific object-directed daily action presented on a computer screen, and afterward they performed what they have observed, 5 repetitions of each task, time duration was noted . 16 motor tasks related to their daily living that were performed with their own hands which are following 1. Folding a towel 2. Cutting a toilet roll 3. Using scissors 4. Tightening shoelaces 5. Opening and closing a square airtight container 6. Opening a bottle top 7. Turning a faucet 8. Using a field of billfold 9. Drinking water 10. Setting a seal 11. Changing batteries 12. Opening and closing a zipper 13. Turning over pages of a book 14. Plugging the outlet 15. Spraying water with a sprayer 16. Sorting chopsticks and spoons and putting them in a box • The participants were advised to keep focusing on their affected arm/hand action observational tasks
In the VRT group, participants will execute VR-based activities conducted by the same therapist. * 16 tasks will be assigned in each session. VR SHINECON 3D Glasses will be used * The virtual environment was set in a 6 m2 physical space * At the beginning of each session, the participant will sit in the center of the set zone and will be assisted to wear the VR glasses * After the participant will confirm that the sight and sound is clear and comfortable, the tasks mentioned in action observation therapy will be done using virtual reality videos * The Extrinsic feedback will be provided, including the time left, number of repetitions, and record number of repetitions
