The goal of this case study is to examine the effects of Photobiomodulation (PBM) on neuropathic pain and sensation post-mastectomy in one female participant.
The main question\[s\] it aims to answer are:
* Will there be a difference in subjective neuropathic pain reported after application of PBM using red and near-infrared wavelengths?
* If a difference in symptoms is discovered, how many sessions were administered before such difference was noted?
* Will there be an observed difference in sensation assessment after application of PBM using red and near-infrared wavelengths?
* Will there be an observed difference on upper extremity mobility following application of PBM using red and near-infrared wavelengths?
* Will there be a subjective difference in quality-of-life following application of PBM using red and near-infrared wavelengths?
Participants will be asked to participate in:
1. Initial sensation, range of motion, strength, pain, and quality of life assessments.
2. Observation and demonstration of the PBM application with a study investigator present.
3. Application of the PBM device to both sides of the chest over the breast tissue for a total of 30 seconds 3 times a week for 6 weeks in the participant's home environment without a study investigator present.
4. Documentation of pain and skin observation/sensation after each treatment session.
5. Follow-up assessments of sensation, range of motion, strength, pain, and quality of life at the end of week 6 after all PBM treatments have been conducted.
6. Weekly monitoring of pain, and skin observation/sensation during weeks 7-10 in the absence of treatment intervention.
7. Follow-up telephone calls by a study investigator during weeks 7-10.
Researchers will compare pre and post assessment results of sensation, pain, range of motion, strength, and quality of life for any changes as a result of the PBM therapy.
