Neurotech Vital Device For The Treatment Of Stress Urinary Incontinence

The study involves wearing a device that includes a wired garment around the hip and bottom area for a period of 30 minutes, 5 days out of 7, for 12 weeks. During this treatment, electrical stimulation is passed through skin contact electrodes (large sticky black pads) which causes the pelvic floor to contract and relax, without you having to do anything. This treatment is not painful and is very similar to the workout you would get from relaxing and contracting your pelvic floor muscles yourself, however the device produces a much stronger contraction.

The study is open to females who have failed a 6 week exercise programme and have been diagnosed with Stress Urinary Incontinence. It will take place at hospital uro-gynaecology clinics/continence clinics across the United Kingdom. The study could last up to 16 months.

This study is being carried out to further prove that the Neurotech Vital device is an effective way of treating stress urinary incontinence in female participants.The study will look at the results of a 12 week treatment programme with the Neurotech Vital device compared to the modified Neurotech Vital device. It will compare the following:

• how much urine is lost in a standard 1 minute stress test carried out at the baseline visit (start of the treatment) right through to visit 5 (end of the treatment - 12 weeks).
• How much improvement is shown in the quality of life questionnaire (this is measured by ticking questions which have scores attached to them and adding up the total score for the questionnaire). This questionnaire asks questions on quality of life which is affected by stress urinary incontinence.

Inclusion criteria

• Subjects who are female and at least 18 years of age.
• Subjects who have signed informed consent form prior to any study related activity.
• Subjects who have previously failed a 6 week volitional pelvic floor muscle training programme or in the Investigators opinion an equivalent lifestyle and exercise programme.
• Subjects who have been clinically diagnosed with stress urinary incontinence and demonstrate a >4g urine leakage following a standardised 1-minute stress test at 1 hour post-bladder filling protocol (1-hour pad weight test). Stress urinary incontinence is defined as complaint of involuntary leakage on effort or exertion, or on sneezing and coughing' (International Continence Society).
• Subjects who have scored at least 18 out of 27 for the Stress Incontinence Questions and are confirmed as having predominant stress urinary incontinence on the Medical, Epidemiologic and Social Aspects of Aging Urinary Incontinence (MESA) Questionnaire completed at the screening assessment.
• Subjects with a Body Mass Index of ≤ 40 kg/m2
• Subjects who are able to give voluntary, written informed consent to participate in this study and from whom consent has been obtained.
• Subjects who are able to understand this study and are willing to complete all the study assessments.

Exclusion criteria

• Subjects who have an existing medical condition that would compromise their participation in the study.
• Subjects who have a physical condition that would make them unable to perform the study procedures.
• Subjects who have any respiratory condition including a chronic cough or history of same.
• Subjects with a history of an underlying neurological condition.
• Subjects with a history of low back pain involving the spinal nerve root.
• Subjects who are currently taking medication, or have taken medication in the last 4 weeks, for urinary incontinence or that effect urinary output function including anti-cholinergics or anti-histamines or any anti-anxiety medications.
• Subjects with a blood clotting disorder or who are taking anti-coagulant medications.
• Subjects who have previously had any uro-gynaecological related surgery excluding hysterectomy.
• Subjects with a clinical diagnosis of prolapse greater than Stage 2.
• Subjects who are pregnant or could be pregnant.
• Subjects who are less than 6 months post-partum or who are lactating.
• Subjects who have any intra-uterine devices or metal implants in the pelvic area, including hip and lumbar spine.
• Subjects with pelvic pain or fibromyalgia or paravaginal defect.
• Subjects with an active implanted medical device (i.e. pacemaker, pump etc).
• Subjects with a history of heart disease or stroke.
• Subjects with a known cancer.
• Subjects with an injury or disability affecting any part of their body which will be in contact with the garment.
• Subjects who are currently involved in any injury litigation claims.
• Subjects who have participated in a clinical study in the last 3 months or any previous clinical study with Bio-Medical Research Ltd.
• Subjects who have been committed to an institution by virtue of an order issued either by the courts or by an authority.
• Any vulnerable subjects defined as individuals whose willingness to volunteer in a clinical study may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate. Examples are members of a group with a hierarchical structure, such as medical, pharmacy, dental and nursing students, subordinate hospital and laboratory personnel, employees of the pharmaceutical and medical device industry, members of the armed forces, and persons kept in detention. Other vulnerable subjects include patients with incurable diseases, persons in nursing homes, unemployed or impoverished persons, patients in emergency situations, ethnic minority groups, homeless persons, nomads, refugees, minors, and those incapable of giving consent.
