Brain-behavior Associations of Sensorimotor Therapy Post Stroke

January 16, 2020 updated by: Geert Verheyden, Universitaire Ziekenhuizen KU Leuven

Behavioral and Brain Connectivity Analysis of Upper Limb Sensorimotor Rehabilitation Post Stroke: a Randomized Controlled Trial

Stroke survivors often encounter impairments in the upper limb after stroke. Sensorimotor impairments are present in 67% of the stroke patients, resulting in problems with independency and performance of activities of daily life. In addition, the pattern of recovery in the brain is still a matter of ongoing debate. Although the importance of somatosensory function on motor performance is well described, evidence for somatosensory or sensorimotor therapy and brain-related changes is scares. Therefore, we aim to explore the effect of a sensorimotor therapy compared to pure motor therapy on motor function of the upper limb. A second objective is to investigate therapy-induced brain-behavior associations using resting state functional Magnetic Resonance Imaging of the brain.

Detailed Description

Stroke survivors often encounter impairments in the upper limb after stroke. Sensorimotor impairments are present in 67% of the stroke patients, resulting in problems with independency and performance of activities of daily life. In addition, the pattern of recovery in the brain is still a matter of ongoing debate. Although the importance of somatosensory function on motor performance is well described, evidence for somatosensory or sensorimotor therapy and brain-related changes is scares. Therefore, will conduct a Randomized Controlled Trial with three main objectives.

The first objective of this project is to investigate the effect of sensorimotor therapy on motor function of the upper limb. To achieve this objective, a sensorimotor program will be developed based on the SENSE therapy. Patients will be randomly allocated to either the sensorimotor therapy group or the pure motor therapy group; and will receive 16 hours of therapy. Motor and Somatosensory assessments will be performed at three time points: baseline(admission to rehabilitation center), immediately after the 16 hours of therapy and after 4 weeks of follow-up.

The second objective is to investigate therapy-induced brain-behavior associations with resting state functional connectivity. In order to achieve insights in brain-behavior associations, we will perform resting-state functional Magnetic Resonance Imaging (fMRI) scans at the same time points as the clinical assessments: baseline, immediately after the 16 hours of therapy, and four weeks after the end of the therapy. Both measurements, brain-imaging and clinical measurements will be combined to investigate the associations.

This project will lead to new insights in brain-behavior associations of sensorimotor function of the upper limb after stroke and will provide evidence for a new therapy in upper limb stroke rehabilitation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: sensorimotor therapy
sensorimotor therapy will consist of 30minutes of sensory discrimination training and 30 minutes of sensorimotor training per session. The sensory discrimination training is based on on the SENSe training of Carey et all. The sensorimotor training is the same individually tailored motor therapy as described below, but with integration of sensory discrimination training aspects.
The intervention will consist of additional physiotherapy for the upper limb after stroke consisting of sensory discrimination training and sensorimotor training.
Active Comparator: motor therapy
The motor therapy consists of 30 minutes of cognitive and attention-based table top games and 30 minutes of motor training per session. The cognitive-attention-based therapy consists of table top games such as chess, rush hour, or other smart games. Individually tailored motor therapy consists of a unilateral motor exercise program for the upper limb, while seated at a table, under supervision of a therapist to match the therapy and intensity provided in the other sensorimotor therapy group. This 30 minutes of motor arm training is based on a set of standardized exercises which comprise task-related practice for gross movements and dexterity including different grips and selective finger movements, and training in daily life activities, however without any attention to sensory discrimination training.
The intervention will consist of additional physiotherapy for the upper limb after stroke consisting of cognitive-attention based training and motor training
