- Brief Summary
To investigate the impact of algorithms utilizing artificial intelligence technology and computer vision on the recovery of motor functions within the context of rehabilitation practice for patients who have experienced a cerebral stroke.
- Detailed Description
Progress in artificial intelligence (AI) technologies and their practical application across various fields, notably in medicine, showcases their potential in solutions such as automated diagnostic systems, unstructured medical record recognition, natural language understanding, event analysis and prediction, information classification, automatic patient support via chatbots, and movement analysis through video. Currently, diverse AI-based software systems are being developed, designed to solve intellectual problems akin to human thinking. AI's widespread applications encompass prediction, evaluation of digital information (including unstructured data), and pattern recognition (data mining).
Amid rapid advancements in deep machine learning, particularly in image and pattern recognition, medical image analysis has gained prominence within automated diagnostic systems, particularly in radiation diagnostics. With the burgeoning field's rapid growth, curating medical datasets for AI-based diagnostic system training and validation is crucial.
AI's success in radiation diagnostics and its recognition as promising within scientific circles pave the way for video analysis and machine learning's integration into medical rehabilitation practice. Collaborating, researchers at the Federal Medical Research Center of the FMBA of Russia and MTUCI devised a plan to develop specialized algorithms based on video movement analysis and machine learning for stroke patients undergoing medical rehabilitation.
These algorithms monitor patients' movements and promptly notify them of deviations, amplitude reductions, or compensatory patterns, aiding them in correcting their movements. All session data is archived electronically, accessible to medical professionals responsible for individualized lesson plans. This enables assessment of patient progress and necessary adjustments to the home rehabilitation program.
Incorporating AI-driven video analysis and machine learning into medical rehabilitation holds great potential for enhancing patient outcomes and personalizing treatment strategies.

Group Intervention Description Habilect patients Habilect patients Patients will receive rehabilitation training using the Habilect software and hardware complex, in addition to standard rehabilitation interventions for the upper limb. AssistI patients AssistI patients Patients will receive rehabilitation training using the AsistI software package in conjunction with standard upper limb rehabilitation interventions.
- Primary Outcome Measures
Name Time Method The Action Research Arm Test (ARAT) Change from baseline at 3 weeks Is a 19 item observational measure used by physical therapists and other health care professionals to assess upper extremity performance (coordination, dexterity and functioning) in stroke recovery, brain injury and multiple sclerosis populations. Scores on the ARAT may range from 0-57 points, with a maximum score of 57 points indicating better performance. MCID has been suggested as 5.7 points
Muscle strength was assessed using the MRC (Medical Research Council Weakness Scale) Change from baseline at 3 weeks MRC is a commonly used scale for assessing muscle strength from Grade 5 (normal) to Grade 0 (no visible contraction). Paresis is defined as light at compliance with strength 4 points, moderate - 3 points, pronounced - 2 points, rough - 1 point and with - 0 points.
Fugl-Meyer Assessment Scale for upper extremity assessment (FMA-UE) Change from baseline at 3 weeks In this study, we wiil use 36 items of the upper arm (proximal musculature, FMA-UA), 24 items of wrist and hand (distal musculature, FMA-W/H), 6 items of aspects of coordination, 12 items of aspects of sensation, 24 items of aspects of passive joint movement, 24 items of joint pain. So the maximum total score on this FMA-UE scale was 126 points.
- Secondary Outcome Measures
Name Time Method The number of exercises completed Change from baseline at 3 weeks Correct repetition count: Number of attempts without compensation, e.g., shoulder or torso movements.
The speed of movement of the upper limb Change from baseline at 3 weeks Upper limb movement speed: Time to reach the target (sec).
Accuracy of performed movements Change from baseline at 3 weeks Movement accuracy: Precision in touching guided points (angles).
Total number of repetitions Change from baseline at 3 weeks Repetition count: Number of motor attempts for the goal.
The correctness of the exercises Change from baseline at 3 weeks Exercise correctness: Number of compensatory actions like shoulder elevation or torso bend.
The number of exercises not completed Change from baseline at 3 weeks Incorrect repetition count: Number of attempts with compensatory actions, e.g., shoulder lift or torso bend.
