Study information

Scientific title

Enhancing the effect of physical therapy for motor impairment after stroke with Theta Burst Stimulation


TBS Study

Study hypothesis

In this study we plan to investigate whether brain stimulation can be used as an add-on treatment to consolidate the benefit from patterned upper limb physiotherapy and induce further hand motor improvement in chronic stroke patients.

To stimulate the brain we plan to use Theta Burst Stimulation (TBS), a novel paradigm of repetitive transcranial magnetic stimulation (TMS), aiming to increase cortical excitability of the affected (ipsilesional) hemisphere.

According to evidence so far, we believe that increased ipsilesional excitability can be achieved by:
1. Direct facilitation of the affected hemisphere (ipsilesional facilitation)
2. Inhibition of the unaffected hemisphere (contralesional inhibition)

Primary aim:
To investigate whether daily treatment with TBS followed by patterned physical therapy for a period of two weeks can lead to significant and sustained improvement of hand motor behavior in chronic stroke patients.

Secondary aims:
1. To study the physiological correlates of the potential behavioral gains
2. To identify physiological predictors of likelihood of response to the proposed intervention, so that appropriate patients may be targeted in future trials

Physiological correlates will be studied using TMS and functional magentic resonance imaging (fMRI) as detailed below.

Topic: Stroke Research Network; Subtopic: Rehabilitation; Disease: Therapy type


Physical therapy (physiotherapy):
The protocol for physical therapy has been developed in collaboration with the therapy services department at the National Hospital for Neurology and Neurosurgery. It expands upon previous protocols by ensuring the equivalence of task intensity, repetition rate and verbal feedback across subjects. Treatment will be task oriented and individualised based on the findings of a questionnaire about current functional difficulties and an objective examination.

Theta Burst Stimulation:
TMS is a well tolerated method of stimulating the human cortex through the intact scalp. We will employ a new pattern of repetitive TMS called Theta Burst Stimulation (TBS). Each burst consists of 3 low intensity (80% aMT, see further on) stimuli, repeating at high frequency (50Hz). Bursts are repeating at 5Hz, i.e. the "theta" rhythm of the EEG. A total of 15 pulses are delivered per second. TBS effect on corticospinal excitability can be either inhibitory of facilitatory, depending on the pattern.

Follow up length: 3 months
