Goals of the Experiment
To reduce the burden of complex regional pain syndrome (CRPS):
- CRPS is a chronic pain that lasts for more than a half a year (Stanton-Hicks, 2018);
- The pain is a manifestation of an injury (Stanton-Hicks, 2018);
- It often has influence on only a single limb (Stanton-Hicks, 2018);
- Research suggests that CRPS emerges as a result of damage incurred by nervous systems (Boesch et al., 2016).
Proposed Solution
- Visual manipulation of a painful region of the body has the potential to decrease perceived pain.
- Mirror therapy is a cost-effective solution and the desired illusionary intervention in this experiment;
- Costly alternatives, such as the use of Virtual Reality has not shown significant benefits (Harvie et al., 2020).
- The idea is that painful limb is hidden behind a mirror and the patient sees the movement of the other limb that is healthy.
- After perceiving that there are no visual distortions of the painful limb, pain starts to decline.
Possible Factors Affecting the Results
- If a movement of a limb causes unbearable pain, then the patient may not wish to proceed with the experiment.
- Some chronic pains may be caused by physical damage to the tissue, and therefore, manipulating the body part’s perception may not help (Pamment & Aspell, 2017).
- Impatience of individuals who expect immediate results may negatively contribute to the results of the experiment.
Discussion
- The experiment will succeed in most cases, because:
- Pain is often subjective.
- Nervous system is responsible for pain, illusions may act as a painkiller.
- In cases when employing illusions for treatment of pain is possible, illusions are a better alternative to using opioids, because:
- Opioids have many adverse effects, including both physical and cognitive outcomes (Chung et al., 2019).
- Opioids may cause dependence, which may later result in substance abuse (Chung et al., 2019).
