Background and study aims
Stroke is a serious, life-threatening medical condition that usually happens when a blood clot or haemorrhage cuts off the blood supply to an area of the brain. Symptoms vary according to how much of the brain is affected and where in the brain the stroke occurs, but include paralysis, muscle weakness and speech difficulties. A stroke can also have an impact on the sufferers' emotions and can lead to anxiety, depression and personality changes. The PULSE study aims to measure whether wearing a device called the Tipstim glove and using a pulse generator for approximately 45 minutes a day can improve the feeling and function of the hand and arm in patients who have difficulties using the upper limbs after a stroke. There are scientific theories that by applying Repetitive Sensory Stimulation (RSS) to the upper limb, the growth of new nerve cells in the brain can be encouraged. This is particularly important for stroke patients where brain cells have been destroyed during the stroke.
In this study, patients who have been treated using the TipStim glove in addition to the conventional treatment after a stroke will be compared to patients who have had conventional treatment only to see whether the glove improves upper limb function in stroke patients.
Who can participate?
Adults (aged at least 18) who have recently had a stroke that has affected the functioning of their upper limbs (arm and hand).
What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 receive conventional treatment. Participants in group 2 receive conventional treatment and the Tipstim glove treatment. The glove works by producing electrical impulses; these are felt in the fingers as sensory pulsations.
It can be worn at any time, for example, whilst watching television or reading and the participant doesn’t have to do anything other than wear the glove. Participants are asked to wear the glove at least 45 minutes a day for three months. All participants are assessed at the start of the study, 2 weeks into the study and again 3 months later. Assessments take the form of interviews and physical arm tests.
What are the possible benefits and risks of participating?
Participants who are treated with the Tipstim glove may benefit directly from taking part if the study shows that it improves recovery after stroke. Some patients also find it helpful to be part of a research study and be under regular follow-up. The result of the study will help researchers improve the future treatment/care of stroke patients. Apart from the possible inconvenience of the researcher taking up some of the participant's time, there are no particular risks from taking part. In some individuals following a stroke, the limb is more susceptible and at risk of damage; •The hand may be swollen and participants may experience changes to the skin of the hand whilst wearing the glove- redness, ulcers, damage/soreness to skin. Some participants may notice a painful shoulder on the affected side or Spasticity or contractures of the affected hand. In rare cases, participants may experience an epileptic fit.

| Scientific title | PULSE - effect of rePetitive Upper Limb Sensory stimulation immediately after a strokE: a pilot randomised controlled trial |
| Study acronym | PULSE |
| Study objectives | The addition of an intervention for post stroke patients –i.e. Repetitive Sensory Stimulation (RSS) via Tipstim glove plus standard treatment for stroke will prove more beneficial in improving sensory-motor function than standard treatment alone. |
| Ethics approval(s) | North West - Liverpool Central Research Ethics Committee, 22/11/2016, ref: 16/NW/0771 |
| Health condition(s) or problem(s) studied | Stroke |
| Intervention | Patients will be randomised into one of two groups- the intervention or non-intervention group; this randomisation will be computer generated and stratified according to the National Institute of Health Stroke Score (NIHSS); patients will be allocated according to their arm score- group score of 1/2 or 3/4. Tipstim glove –the intervention. The glove (various sizes) will be applied onto the affected hand, attached to the generator and switched on. The pulse sequence will be set individually at the highest threshold the patient can comfortably tolerate for the daily 45 minute session. This level will be recorded on each patient research record. The glove is fitted with tiny microprocessor electrodes which transmit pulses to various areas of the fingertips in a repetitive mode. These may be felt by the patient as tingles and known as sensory stimulation= RSS. The patient is free to move around if mobile, read or watch TV etc. during this 45 minutes. After 45 minutes, the researcher/patient/nurse will switch off device and remove glove and observe any adverse events- redness, swelling etc., and note any comments made by patient. The sessions will continue daily, preferably around the same time for two weeks. Both groups will continue with standard treatment therapies as per protocol for standard care. Standard care encompasses a variety of interventions. Treatment sessions are carried out by an occupational therapist or physiotherapist or joint occupational therapist/ physiotherapist in the treatment room, in upper limb group, in exercise group, in breakfast club, in washing and dressing activities and on home visits. Rehabilitation of the upper limb includes: 1. Task-specific training/ repeated practice including: 1.1. Repetitive upper limb facilitation in function in meaningful activities of Daily Living (ADL) 1.2. De-weighting before “placing” hemi arm in space 1.3. Positioning in alignment with anticipatory postural adjustment (APA) trunk control 1.4. Scapula stabilisation and tone management 1.5. Splinting of the hand and provision of shoulder supports (Omoneurexa) 1.6.. Postural sets to allow upper limb reach and grasp activities 1.7. Napier Grip practice 1.8. Chedoke outcome measure 1.9. Facilitated “GRASP” repetitive exercises 1.10. Bedside activities including thera-putty and GRASP 1.11. Affolter approach using upper limb for co-ordination 1.12. Sensory stimulation includes: 1.13. Retrograde massage 1.14. Sensory bombardment, stimulate distal key points, open hand for reach and grasp with visual contact of palm and thumb 1.15. Contractual Hand Orientation response 1.16. Passive stretches and facilitation of full range of movement 1.17. Weight bearing and balance co-ordination For the intervention group, face to face interviews and assessments will take place immediately on recruitment, 2 weeks later on completion of RSS intervention and 3 months later. |

| Target number of participants | After analysing our local National sentinel audit for stroke data from 1st of April 2015 to 31st of March 2016, we found that 57 patients were meeting the study criteria. Therefore, it would be practical include 40 to 60 patients for this pilot trial over one year two months period. |
| Total final enrolment | 40 |
| Key inclusion criteria | 1. Age 18 years or over 2. Male and female 3. Unilateral stroke (both ischaemic and haemorrhagic) with sensory motor arm/hand weakness (2 days to 2 weeks) post stroke 4. Baseline National Institute of Health Stroke Scale (NIHSS) arm motor score of 1-4 5. Pre-stroke modified Rankin Scale (mRS) of 0-3 6. Signed informed consent or witnessed verbal consent |
| Key exclusion criteria | 1. Patients with transient ischemic attack with symptoms lasting less than 24 hours 2. No arm weakness 3. History of epilepsy 4. Patients with permanent pacemaker 5, Aphasia, or cognitive impairment that prevented completion of the baseline assessment 6. Patients with dermatitis or oedema of the affected hand Inclusion in another research study, including another randomised controlled trial, does not automatically exclude a patient from participating in this trial. As long as inclusion in the other study would not confound the results of this trial, co-enrolment will be permissible. |
