MIRROR IMAGE THERAPY
Have you tried mirror image therapy for your CRPS / RSD or your chronic pain condition? Mirror therapy has various titles including mirror imagery, mirror therapy, mirror visual feedback, imagery therapy, mirror image therapy… But essentially it all comes down to a non invasive, completely drug free alternative therapy to help you and your chronic pain.
This blog will deal with both Mirror Therapy and also Graded Motor Imagery programme or GMI which is an up to date rehabilitation programme.
The idea behind mirror therapy is to try and ‘trick’ or retrain your brain / your mind into thinking you are moving your limb or digit; foot, leg, arm, hand, fingers, toes without pain and freely. Apparently the brain can be effectively taught to move normally and not to think that it is in pain, this all takes a bit of practice.
1 of the team behind Burning Nights CRPS Support has tried using mirror therapy for her Complex Regional Pain Syndrome as a treatment in summer 2004, 11 years ago but unfortunately it did not work for her. She was having physiotherapy for her CRPS at a local hospital and she had just been given a new physio for her treatment plan and she was really into alternative therapy for chronic pain sufferers like her. The physio had read about mirror therapy in the Physiotherapy magazine as it had been a double page feature about some Australian physios using mirror therapy for their pain patients. So her new physio decided we would try it which she did. After trying the therapy on several occasions they found that it just wasn’t working for her. However that is not to say that it doesn’t work for anybody, because each individual CRPS sufferer reacts differently to every available treatment for CRPS. That is the thing with CRPS / RSD because all of our symptoms are different we are all individual in a way with this pain condition.
HOW DOES IT WORK?
Mirror therapy was originally used to treat phantom limb pain (Ramachandran V.S. et al. 1996). In the research study undertaken by McCabe, C.S. et al (2003) they say that:
“The mirror reflection permits the subject to rehearse and practice movements of the affected limb without having to directly activate those parts of maladaptive central processes that typically produce pain.”
According to Mosely, G.L. (2004) in their research they said:
“Complex regional pain syndrome type 1 (CRPS1) involves cortical abnormalities similar to those observed in phantom pain and after stroke. In those groups, treatment is aimed at activation of cortical networks that subserve the affected limb, for example mirror therapy.”
But Mosely, G.L. (2004) also says about mirror therapy:
“However, mirror therapy is not effective for chronic CRPS1, possibly because movement of the limb evokes intolerable pain.”
In another research study Mosely, G.L. et al. (2008) they stated that:
“Motor imagery increased pain and swelling in patients with chronic painful disease of the arm. The effect increased in line with the duration of symptoms and seems to be modulated by autonomic arousal and beliefs about pain and movement. ”
However contrary to the research by Mosely, G.L. et al (2008) in a different study a year later Ezendam, D. et al. (2009), they showed:
” … a trend that mirror therapy is effective in upper limb treatment of stroke patients and patients with CRPS…”
The results from mirror therapy are different depending on which research study you read, and even though mirror therapy may have worked for some CRPS sufferers in McCabe, C.S. et al. (2003) research they found that after stopping the mirror therapy the pain returned to the CRPS sufferers:
“…when the intervention is stopped there is an abrupt return of pain.”
So as you can see there are inconsistencies even in the research world about mirror therapy for CRPS. Cacchio, A. et al (2009) in their comments regarding research on mirror box therapy stated:
“.. the use of mirror therapy and therapy involving imagery of movement in patients with chronic complex regional pain syndrome type 1 (lasting 6 months or more) remains controversial.”
In a recent study by Breivik, H. et al (2013) they said:
As for phantom pain, attacking the “neglect-like” symptoms of CRPS with mirror-therapy may normalize the functional disorganization in the CNS, contributing to restoring functions and abolishing the pathological pain.
WHAT TO DO
Find yourself either a fairly big mirror or you can purchase a mirror box from the internet. However an ordinary mirror works just as well in fact better if you have your CRPS pain condition in your lower limbs.
- Find yourself a relaxed place where you won’t have any distractions
- Get yourself in a comfortable sitting position
- Remove any jewellery, so your limb is completely bare and free of any distractions
- If you have a mirror box then place your affected CRPS/RSD limb inside the box with the mirror on 1 side and your other ‘good’ limb in front of the mirror. If you are using a simple mirror then place the mirror between your 2 limbs i.e. between your legs. If your CRPS is in your arms or hands then put the mirror on a table between your arms/hands
- Take a look in the mirror and you should see the reflection of your ‘good‘ limb which will look like your opposite limb but in a good normal state rather than seeing your CRPS affected limb
- Begin some gentle movements or exercises of your unaffected ‘normal’ limb continue to look and focus your attention on the image in the mirror. It looks like you are moving your CRPS affected limb doesn’t it?
- Keep focusing and thinking that you are actually moving and exercising your CRPS affected limb. The idea is to ‘trick’ your mind into thinking that you are moving the bad limb
- Repeat the exercise you may have been given by your physiotherapist. If you don’t have any exercises, there are some suggestions below
- Try and do some exercises little and often, for example every day
- Don’t continue if you are in severe agony because of the movements or your limb starts to sweat then you could have pushed it a little too far, so please be careful!
Some possible exercises you could try with the mirror therapy:
- looking into the mirror and concentrate on the image that you see whether it is your hand, arm, foot or leg
- move each finger separately
- tapping each finger separately and then 2 fingers, 3 fingers, then all fingers
- moving your ankle up and down
- moving your ankle in circles
- flattening out your hand
- taking a small weight on your flattened hand
GRADED MOTOR IMAGERY PROGRAMME or GMI
GMI was developed by Professor Lorimer Moseley and is an up to date rehabilitation programme that has been based on clinical trials and the latest science. We already are aware that the brain in CRPS sufferers perceive any touch no matter how soft or hard as painful. The idea behind both mirror therapy and GMI is to help ‘retrain the brain’ to not be painful and in recent studies it has been shown to be effective in reducing pain levels and also improving function.
According to Johnson, R. (2014) he states that:
“GMI as a treatment is focused on training the brain to re-connect to the body part affected by pain. When you have CRPS in one part of your body, your brain “disowns” the body part, recognizing it as threat, instead of your hand or foot. When your brain recognizes a threat to your survival, it produces pain to protect you. It is an alarm system that goes off so you can treat the injured area. However, in cases of CRPS, this alarm system is faulty.”
The GMI programme involves 3 stages that exercises the brain in different ways. Those stages are:
- Left/Right discrimination – Identify left or right images of their painful limb or body part
- Explicit motor imagery – Thinking about moving without actually moving
- Mirror therapy – As in earlier in the blog

HOW DOES THE GMI WORK?
According to the Ranelli, S. (2013) GMI uses 2 main tools including:
- Flash cards – which are a random collection of pictures of hands and feet in different postures and position and doing different tasks. They are used to help re-train the ability to recognise where the body or body part is in space
- A computer program called ‘Recognise’
- This tool uses the same pictures as in the flash cards and also assesses your accuracy (how many of the positions and postures you recognise correctly as left or right side) and the time it took for you to record your response
- This means that you can take a step-by-step approach to improving your recognition ability and this is usually associated with a decrease in pain and an improvement in your function.
Here is an video example of the ‘Recognise’ programme used in GMI:
