Massage therapy modulates energy metabolism and alleviates skeletal muscle spasms in rats.

Researchers investigated how massage therapy affects muscle metabolism in rats experiencing muscle spasms, a common problem that occurs after injury, intense exercise, or neurological conditions. The study used twenty-four rats divided into three groups: normal controls, rats with exercise-induced muscle spasms, and rats with muscle spasms that received kneading massage treatment. The researchers measured pain levels, blood flow properties, waste products in muscles like lactic acid, and examined the detailed structure of muscle tissue under powerful microscopes. They also analyzed the chemical makeup of muscles to understand metabolic changes. The results showed that massage therapy provided significant benefits for rats with muscle spasms. Compared to untreated rats, those receiving massage had reduced pain sensitivity, better blood flow, and lower levels of lactic acid and other waste products that accumulate during muscle fatigue. Under the microscope, muscle fibers in massaged rats appeared more organized with clearer structural patterns and more energy-producing mitochondria. The metabolic analysis revealed that massage influenced 136 different chemical compounds in the muscles, particularly those involved in energy production and metabolism. The massage appeared to work by improving how muscles generate and use energy, specifically affecting pathways related to glucose breakdown, fat metabolism, and other energy systems. While this study used rats rather than humans, it provides scientific evidence for how massage therapy might relieve muscle spasms and pain through metabolic improvements. If you're considering massage or related therapies like acupuncture for muscle problems, consult with a licensed and qualified practitioner.

This experimental study examined massage therapy's metabolic mechanisms in skeletal muscle spasm using twenty-four Sprague-Dawley rats divided into control, model, and massage groups. Exercise-induced fatigue established muscle spasm in experimental groups, with kneading manipulation applied to the massage cohort. Outcomes assessed included mechanical withdrawal threshold (MWT), thermal withdrawal latency (TWL), hemorheological parameters, lactic acid (LA), and blood urea nitrogen (BUN) levels. Transmission electron microscopy evaluated gastrocnemius ultrastructure, while liquid chromatography-mass spectrometry performed metabolomic profiling. Results demonstrated massage significantly improved MWT and TWL while reducing oscillation frequency, blood viscosity, plasma viscosity, and LA/BUN levels compared to untreated spasm models. Ultrastructural analysis revealed improved myofibril organization with enhanced mitochondrial presence. Metabolomics identified 136 differential metabolites between groups, predominantly affecting glycolysis, pentose phosphate pathway, inositol metabolism, and lipid metabolism. Clinical relevance: Massage therapy alleviates muscle spasm through modulation of energy-related metabolic pathways, providing mechanistic evidence for manual therapy's therapeutic effects on musculoskeletal pain and circulatory dysfunction.
