Trial Summary

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What data supports the idea that Cognitive-Somatosensory-Motor Training for Stroke is an effective treatment?

The available research shows that Cognitive-Somatosensory-Motor Training can improve motor function in stroke patients. For example, one study found that somatosensory stimulation, which is part of this training, led to better hand motor function in patients with chronic strokes. This improvement was greater than in sessions without this stimulation, and the benefits lasted for at least 30 days. This suggests that the treatment can be a helpful tool in stroke rehabilitation, especially for those with certain types of brain injuries. ^{1 2 3 4 5}

What safety data exists for Cognitive-Somatosensory-Motor Training for stroke?

The provided research does not directly address safety data for Cognitive-Somatosensory-Motor Training or its variants like iCOSMO. The studies focus on the effectiveness of somatosensory retraining and stimulation in improving motor function after stroke, but they do not specifically mention safety outcomes or adverse effects related to these interventions. ^{1 3 4 6 7}

Is the treatment Cognitive-Somatosensory-Motor Training for Stroke promising?

Yes, Cognitive-Somatosensory-Motor Training for Stroke is promising because it combines physical and sensory training to improve motor and sensory functions in stroke patients. Studies show that somatosensory stimulation can enhance motor function and help maintain training benefits, making it a valuable tool for stroke rehabilitation. ^{2 3 4 6 8}

What is the purpose of this trial?

The iCOSMO study investigates the feasibility and beneficial effects of an intervention combining sensation, motor and cognition to improve arm and hand function after chronic stroke.

Treatment Details

Interventions

• integrated Somatosensory-MOtor training using a COgnitive approach(iCOSMO)

Trial Overview This study tests two types of training programs: GRASP, which patients do at home, and iCOSMO, which integrates sensory, motor, and cognitive exercises to aid recovery after a chronic stroke.

Participant Groups

Group I: iCOSMO Experimental Treatment 1 Intervention

20 participants will receive the iCOSMO intervention. iCOSMO consists of two training approaches that will include active touch and movement exploratory procedures during goal-oriented tasks as well as robotic training using the Kinarm Exoskeleton device.

Group II: Home GRASP Active Control 1 Intervention

20 participants will receive the control intervention. The control group will receive a matched dose of a home-based exercise programme. The home-based exercise programme will be based on the Home Graded Repetitive Arm Supplementary Program.

Findings from Research

Cognitive sensory motor training therapy showed promising results in improving upper extremity motor function in seven patients with chronic stroke or traumatic brain injuries, with an average increase of 7.7 points in Action Research Arm (ARA) scores over 2.5 months of training.

All patients demonstrated improvement, suggesting that this therapy could be a valuable rehabilitation method, although further studies with larger sample sizes are needed to confirm its efficacy.

The COMPoSE intervention is a novel rehabilitation program designed for stroke patients that integrates both somatosensory and motor training to address upper limb deficits, utilizing a standardized training matrix over 10 sessions in 3 weeks.

This approach includes specific training variables like grasp pressure and object texture, along with feedback mechanisms and high-dose repetitive practice, aiming to enhance skill acquisition and improve functional outcomes in stroke recovery.

Somatosensory retraining programs can significantly improve somatosensory discrimination skills in the arm of stroke survivors, with an average effect size of 0.85 across various modalities, indicating a meaningful impact on sensory recovery.

There is a trend suggesting that these retraining programs may also enhance motor function and arm use, as indicated by narrative analysis of studies involving 89 participants, although more research is needed to confirm these findings.

In a study involving 11 stroke patients with cortical involvement, median nerve stimulation (MNS) significantly improved hand motor function compared to control stimulation, indicating its efficacy as a rehabilitation tool.

Patients who received MNS not only showed immediate improvements but also maintained these benefits 30 days later, suggesting that somatosensory stimulation can help consolidate motor training effects in stroke rehabilitation.

A randomized clinical trial involving 40 ambulant stroke patients showed that combining motor imagery (MI) training with physical practice significantly improved lower extremity muscle strength and gait performance compared to physical practice alone.

The experimental group that received MI training demonstrated greater improvements in hip, knee, and ankle muscle strength, as well as faster gait speed, indicating that MI can enhance rehabilitation outcomes in stroke patients.

In a study of 55 adults with moderate-to-severe upper limb hemiparesis, active somatosensory stimulation combined with motor training significantly improved motor function outcomes compared to sham stimulation, as measured by the Wolf Motor Function Test and Action Research Arm Test.

While the active stimulation showed benefits in motor function, it did not significantly affect the Fugl-Meyer Assessment, and the clinical relevance of the observed differences remains to be determined, suggesting further research is needed to explore its impact on overall disability and recovery.

Recent research highlights the importance of combining training with various interventions, such as somatosensory input and cortical stimulation, to improve motor recovery in stroke patients.

Studies show that these strategies can enhance cortical plasticity, suggesting new ways to optimize rehabilitation efforts and improve outcomes for individuals with stroke-related disabilities.

The scoping review analyzed 117 articles from 2005 to 2015 to understand how adults and older adults process somatosensory information and the interventions available for regaining function after a stroke.

There is a significant gap in knowledge regarding the impact of somatosensory function on daily activities, highlighting the need for a multidisciplinary approach that focuses on performance and participation outcomes in future research.
