A few months back I suffered a high-grade separation of my AC joint at Jiu Jitsu. In lay terms, this means that I tore the 3 ligaments that attach the acromion (the little bony bit that sticks out of the top of the shoulder blade) to the clavicle or collarbone.
Up until the injury, I only had anecdotal reports of how microcurrent therapy could help recovery from injury and I have to admit that I had kinda let the microcurrent application of the Nurokor devices fly under my radar. But that all changed when I sustained the injury and started to look into the research behind the use of microcurrent to help speed the recovery from injuries. The research (see a summary below) looked pretty promising and so, I started to use the Nurokor MiTouch device directly on the injured joint for around 20 minutes following my rehab exercise (which also included around 10 minutes+ of TENS on muscles not causing a contraction in the injured joint). For what it’s worth, I noticed fairly immediate improvements in range of motion, pain, and swelling that did not seem to be related just to normal improvements because on days that I didn’t use the device, I didn’t notice the same effects.
What is microcurrent therapy?
Microcurrent therapy (MENS – microcurrent electric neuromuscular stimulation) is the application of an electrical at a very low ‘dose’. So, it differs from the more common TENS or EMS because it does not create a contraction of muscle. The advantage of this is that:
- Microcurrent can be applied over bones and directly to joints
- The lack of contraction makes it safe for use post-injury (when joint movement would be dangerous or detrimental to recovery)
What does microcurrent do?
Microcurrent therapy has become popular for wound-healing and recovery from injury because it helps to promote improved healing of both bone and connective tissue. [1, 2] It is thought that injured tissue produces abnormal electrical potentials (“injury potentials”) and microcurrent therapy can help to restore the normal electrical balance to tissue, resulting in more rapid regeneration of tissue and return of normal function. 
What are the evidence-based benefits?
Improve the healing rate of soft-tissue
Animal research has shown that microcurrent applied to the skin above damaged connective tissue like meniscus, tendons, and ligaments can speed healing and encourage the growth of healthy tissue. [3-7]
Microcurrent might also speed bone healing after a fracture,8 by inducing greater numbers of bone-marrow stem-cells and satellite cells critical to bone-repair. [7-9]
Improve skin & wound healing
Improved healing times for skin wounds have been observed in controlled trials in animals. [10, 11] In humans, microcurrent therapy has improved wound closure and healing.  Microcurrent therapy has also been demonstrated to be more effective for encouraging wound-healing in burn wounds than negative-pressure wound therapy (a common therapy for burns). 
The previous research also noted improved modulation of inflammatory markers, along with epithelial cells and fibroblasts (cells that help to synthesise collagen).
Microcurrent therapy resulted in reduced pain after mouth surgery.
