Effects of Transcutaneous Electrical Nerve Stimulation on Cognitive Function and Upper Limb Motor Function in People With Chronic Stroke
Study Details
Study Description
Brief Summary
Upper limb impairment is present in more than 85% of people with stroke, which greatly affect the quality of life, social participation, and performance of daily activities of people with stroke. Previous study also revealed that 53.4% of people after stroke experienced cognitive impairment. Different cognitive domains might be affected following stroke, such as attention, memory, language, and orientation, and the problems with memory are often prominent. Yet, there is no effective treatment for the post-stroke cognitive impairment.
Transcutaneous electrical nerve stimulation (TENS) applied on thoracic region and transcutaneous vagus nerve stimulation (tVNS) are simple and non-invasive treatment to improve upper limb motor function and cognitive function. However, no existing studies have explored on the effects of TENS and tVNS on cognitive function in people with stroke. Therefore, the purpose of this study is to evaluate the effectiveness of TENS on improving upper limb function and cognitive function in people with chronic stroke. Also, this study will investigate the cortical response of people with stroke during TENS by using EEG power spectrum analysis.

Detailed Description
This study aims to investigate the effects of three intervention protocols in people with stroke. The participants in Group A will receive TENS on C6 and T5 level of the spine with upper limb exercises. The participants in Group B will receive tVNS on the cymba conchae of left outer ear with upper limb exercises. The participants in Group C will receive placebo tVNS with upper limb exercises.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: spine TENS The participants will be received eighteen 45-minute sessions of intervention, 3 sessions per week for 6 weeks. |
Device: spine TENS
The participants in Group A will receive TENS (Burst mode, 9 pulses per burst, pulse frequency = 160 Hz, burst frequency = 2 Hz) with upper limb exercises. The electrical stimulation will be generated by the neurostimulator (MH8000P; MEDIHIGHTEC MEDICAL CO., LTD., Taiwan). Two 7.5 × 12.6 cm electrodes will be attached between C6 and T5 level on each side of spinal column and with 2 cm from the spine. Intensity of TENS will be individually selected by the participants according to tolerance levels.

Experimental: tVNS The participants will be received eighteen 45-minute sessions of intervention, 3 sessions per week for 6 weeks. |
Device: tVNS
The participants in Group B will receive tVNS (pulse frequency = 25Hz, pulse duration = 0.3 ms) on the cymba conchae of left outer ear with upper limb exercises.The electrical stimulation will be generated by the neurostimulator (MH8000P; MEDIHIGHTEC MEDICAL CO., LTD., Taiwan). Intensity of tVNS will be individually selected by the participants according to tolerance levels. Previous studies showed that it was effective to improve the upper limb motor function in people with stroke and cognitive function in people with mild cognitive function.

Placebo Comparator: Control The participants will be received eighteen 45-minute sessions of intervention, 3 sessions per week for 6 weeks. |
Device: Control
The participants in Group C will receive placebo tVNS with upper limb exercises, where the stimulation will be delivered by placebo-TENS device with disconnected electrical circuit.

Outcome Measures
Primary Outcome Measures
- Electroencephalogram measurement [Baseline (0 week)]
A 20-channel Electroencephalogram (EEG) (Neurostyle Pte. Ltd.; Singapore) will be mounted on the scalp following the 10-20 system to capture the whole-brain EEG. The EEG signals will be collected with a sampling frequency of 256 Hz and then filtered by band-pass filter from 1 Hz to 100 Hz and notch filter of 50 Hz. EEG measurements will be prepared during the 20-minute rest. Before and after the stimulation, EEG signals will be recorded for 3 minutes. During the stimulation, EEG measurements will be also taken for 3 minutes.

The scaled score of each subtest and total scaled score will be computed by converting raw scores based on different age group. Higher scaled score indicates better memory function. The RBMT-3 has demonstrated excellent inter-rater reliability (ICC = 0.997) and intra-rater reliability (ICC = 0.924) and good internal consistency (Cronbach's alpha = 0.643 - 0.832) in people with dementia, mild cognitive impairment and healthy older adults.

- Digit Span Test [Baseline (0 week)]
The Digit Span Test (DST) consists of two parts to measure the verbal short-term memory and working memory of an individual, which are digit span forwards and digit span backwards. The participants are presented with a series of numbers. In the digit span forward (DSF), they are required to repeat the numbers in forward order. In the digit span backward (DSB), they are asked to repeat the numbers in reverse order. The length of digits in each string increases from 3 to 9 in DSF and from 2 to 8 in DSB. Two trials are presented at each length. The test is interrupted when participant failed to either trial at equal digit length. If the participants correctly recall the sequence in either first and second trial, 1 point will be scored. The total score of DSF and DSB are 16 and 14 respectively. The intra-rater reliability of DSF and DSB are 0.891 and 0.598 respectively in older adults with neurocognitive disorder.

- Trail Making Test [Baseline (0 week)]
Trail Making Test (TMT) can assess the attention and cognitive flexibility of individuals. The test is divided into part A and part B. In part A, the circle is numbered (i.e., 1 to 25).

- Oxford Participation and Activities Questionnaire [Baseline (0 week)]
The 23-item Oxford Participation and Activities Questionnaire (Ox-PAQ) evaluates participation and activity levels based on the three domains of routine activities, social engagement, and emotional well-being. Each item is measured on a 5-point Likert scale (0 = never; 1 = rarely; 2 = sometimes; 3 = often; 4 = always). The higher scores represent greater difficulties with participation and activities. Good to excellent internal consistency (Cronbach's α = 0.81 - 0.96) and test-retest reliability (ICC = 0.83 - 0.96) have been shown for this instrument in people with motor neuron disease, multiple sclerosis, and Parkinson's disease.
