This morning as usual John was over an hour in the shower room. I tried several times to get him to come out but he stands under the hot water until it runs out. I then heard a thump and found him on the bedroom floor unable to get up. My guess is the hot water has weakened him. He was unable for ages to straighten up or get dressed and then coming downstairs with his bad knee was a nightmare. I phoned a company in Glasgow recommended to me by his OT and should get a visit this week. They advise me that people with dementia should never use these stair lifts on their own. Can anyone give me advice about what to ask or look out for. Our stair is a straight one with no obstacles such as door or radiator. Thanks.
