The "I have difficulty" question is about the conditions that cause the claimant to have difficulty with completing the activity, for example; due to Osteoarthritis in my knees I only have a 5% bend in the joint this cause me problems with activities such as sitting and raising my legs on to the bed at the end of the day.
The "I need help" question asks the claimant to explain the prompting, assistance or supervision that would allow them to overcome there problems with an activity, so again as an example; I need someone to lift my legs onto the bed as I cannot do this myself.
