Sorry it wasn't helpful. I'll have another try. If you're looking for something more cognitive-behavioural, you need to try and break the cycle that exists between thoughts, feelings, behaviours, thoughts, feelings, behaviours, etc. etc. A thought is always followed by a feeling and the behaviour is a consequence of that feeling - so, for example,
thought: this needle will cause me pain
behaviour: pulls away
Someone tries to encourage him to have the needle in -
thought: this person is going to hurt me
feeling: increased fear
behaviour: struggling to get away. etc. etc.
You can try and break this cycle at any point using your experience of the individual - what does he enjoy doing (behaviours), thinking about (thoughts) or feeling. These can be established before the needle is introduced, so he is distracted and engrossed before the needle appears.
Will he watch a programme, sing a song, have his skin stroked by a feather to evoke a feeling, recall a happy day, stroke a pet, etc.etc. They only seem to be distracting techniques (which they are) but they break the cycle so you have a lower anxiety level before you begin with the needles.
You might want to encourage him to accept the needles more by changing his opinion of them (ie the original thought) which will change the consequential chain of feelings and behaviours, for example,
thought: yes, it might hurt me a little, but it is making me so much more healthy, so it is my friend OR I am big and strong so I can accept it,
feeling: more accepting of the pain
behaviour: less pulling away.
Could you combine this with breathing exercises, which also need concentration but allow the body to relax - deep breathing in for 4, hold for 4, breath out for 6.
You would need to adapt the above for your patient. is this more of what you were looking for? Hope so. Best Wishes, Sarah
