Attendance allowance

Hi My friend has recently been turned down for Attendance Allowance. The reasons for walking around, getting in and out a chair and up and down stairs it stated that, “I consider using a coping strategy and taking your time along with suitable aids you could reasonably be expected to manage in your own time independently and that you do not require frequent attention from another person.” This sentiment carries on through all the reasons why she is capable of carrying all the daily living tasks. I thought that if you can’t do a task reliably without feeling stressed, in pain and in reasonable time, then this would count, has this changed for AA? My friend has arthritis in her back and knee, diabetes, IBS and onset of COPD. I hope someone can let me know if this is correct
