In this research the investigators will test TPTNS compared to dummy treatment in 500 people living in care homes who have urinary incontinence and who wear absorbent pads. The amount of urine they leak into participants' pads will be measured over a 24 hour period after six weeks (at the end of the TPTNS treatment programme) and after three and five months. This will tell the investigators if the treatment works and if it decreases leakage and if so, for how long. The investigators will ask the older person whether they feel their bladder leakage has changed and about any impact on their quality of life. The opinions of close family members and care home staff will be sought regarding whether they think TPTNS has had any effect on the participant. The investigators are also interested to learn about experiences of TPTNS, from residents, family and friends and all the staff involved. Costs of providing this treatment compared to the costs of providing continence care and pads will be determined and. the best ways to give TPTNS treatment in a care home, long term, will be explored with the care home staff.
