Rest may be best medicine to treat some pains

Getting rest may be as effective as taking medication to treat common musculoskeletal disorders such as carpal tunnel syndrome and low back pain, which caused by repeated moderate-strain activitym, scientists have found.

In a study conducted on rats, researchers showed that a  4 week period of rest was nearly as effective as an experimental drug at reducing discomfort and regaining function.

Rest appears to be good first treatment choice, said a researcher.

Other treatments following rest should include exercises to improve tissues, and pain reducers if needed. If symptoms do not subside and strength does not return following this approach, then pharmacological treatments may be needed to aid recovery, the researcher said.

The researchers trained rats to repeatedly pull a lever in order to model the types of repetitive-strain injuries humans experience.

After 12 weeks, the rats showed a weaker grip strength, discomfort and increased collagen production in the forearm- evidence of strain-induced tissue damage.

The researchers then allowed the rats to rest for 4 weeks. During this rest period one group of rats received an experimental drug that blocks a neurotransmitter. Substance P, which is associated with the sensation of pain, while the other group did not.

We found that the 4 week rest treatment reduces collagen production, improved streg=ngth and decreased discomfort, said the Dr.

The drug blocking Substance P signalling also had similar effects, and was somewhat better at improving grip strength, but at the same time made the animals less sensitive to very hot temperatures, which is concerning. This led us to conclude that rest may be the better treatment, she said.

There appears, however, to be a tipping point at which rest is not sufficient and medications are needed, researchers said.

While the study showed rest was sufficient for recovering from repeated moderate-strain activity, previous studies indicated it was not sufficient when the lever was harder to pull, causing more strain.

In investigating the Substance P-blocking agent and other drugs, the researchers are focused on developing ways to help the tissue actually recover from overuse-induced injury, not jsut relieve pain.

In previous experiments the researchers tried giving the rats ibuprofen and other pain relievers while they were performing the lever pulling task, however, this seemed to only mask the pain while allowing rats to continue to pull hard, worsening tissue damage.
