Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Near infrared light (NIRL), using a Vielight 810nm device, will be delivered to participants through a diode placed in their nasal cavity for 25 minutes, 5 times per week for 4 weeks; i.e. 20 sessions in total. The first session will be undertaken in the Urology Outpatient Clinic; thereafter 1 session per week will be delivered by the Study Research Assistant in the participant's home and the other 4 sessions per week self-administered by the participant. Monitoring of adherence to the intervention will be by way of a daily participant diary, weekly research assistant visit and weekly phone call to the participant.

Outcomes
Primary outcome [1] 319882 0
Change in Overactive Bladder Symptom Score (OABSS).
The OABSS is a validated, patient-completed sum score of four symptoms (daytime frequency, night time frequency, urgency, and urgency incontinence) seen in patients with OAB, that has been shown to be sensitive to change after treatment.
Timepoint [1] 319882 0
Immediately after 4-week NIRL intervention.
Primary outcome [2] 319883 0
Change in daytime urinary frequency.
Urinary frequency will be recorded with the assistance of the "time stamp" function on the wrist-worn Actiwatch Spectrum Pro actigraphy device. Participants will be asked to press the button on the device each time they void on 2 days each week for the duration of the study.
Timepoint [2] 319883 0
Immediately after 4-week NIRL intervention.
Secondary outcome [1] 369779 0
Change in International Consultation on Incontinence Questionnaire: Overactive Bladder Quality of Life Module (ICIQ-OABqol) score.
Timepoint [1] 369779 0
Immediately after 4-week NIRL intervention.
Secondary outcome [2] 369780 0
Change in Overactive Bladder Symptom Score (OABSS).
Timepoint [2] 369780 0
4 weeks post NIRL intervention completion.
Secondary outcome [3] 369782 0
Change in daytime urinary frequency.
Urinary frequency will be recorded with the assistance of the "time stamp" function on the wrist-worn Actiwatch Spectrum Pro actigraphy device. Participants will be asked to press the button on the device each time they void on 2 days each week for the duration of the study.
Timepoint [3] 369782 0
4-weeks post NIRL intervention completion.
Secondary outcome [4] 369783 0
Change in International Consultation on Incontinence Questionnaire: Overactive Bladder Quality of Life Module (ICIQ-OABqol).
Timepoint [4] 369783 0
4-weeks post NIRL intervention completion.
Secondary outcome [5] 369784 0
Occurrence of an adverse event.
i) A clinically significant rise in systolic or diastolic blood pressure defined as >=30mmHg. Measured using an automated blood pressure machine with cuff fitted to a participant's upper arm.
ii) Any unintended or untoward incident reported by the patient.
Timepoint [5] 369784 0
i) Immediately prior to, during and immediately following application of NIRL (during sessions delivered by Study Research Assistant).
ii) During, immediately folllowing or post NIRL session.

Intervention assignment
Single group
Other design features
This study will utilise a single-case experimental design (SCED) to enable testing of the efficacy of a novel intervention in a small group of OAB patients with heterogeneous symptoms. This design relies on frequent and repeated measures throughout the baseline, intervention and follow-up phases. Specifically, a non-concurrent, multiple baseline, across-subjects format has been chosen because maintenance of the effect of NIRL intervention is both plausible and desirable.

Statistical methods / analysis
The demographic and clinical characteristics of the participants will be tabled following standard procedure. Appropriate graphical technique(s) will be used to explore the longitudinal changes in both the OABSS and Actiwatch urinary frequency at individual participant level. This presentation will depict both within-phase and between-phase comparisons. If the above analyses indicate any pattern, further simulation-based analyses will be conducted as appropriate.

Summary
Brief summary
Overactive bladder is a term describing the clinical problem of urinary urgency +/-urgency incontinence. It is a bothersome condition that occurs equally in men and women. OAB places a burden on both the individual and the healthcare system. It is associated with reduced quality of life, increased risk of falls, high healthcare utilisation, personal cost and lower work productivity.
This research study is the second part of a two-part study that aims to establish whether intervention with Near Infrared Red Light therapy delivered via a nasal prong can help to reduce the symptoms of overactive bladder. It is hoped that this research will lead to a more effective and standardised treatment plan for people with overactive bladder.
The research intervention (Near Infrared Light) has successfully been used for other conditions where people are in pain.
