Key result
Reflex sympathetic dystrophy is linked to higher tissue pH and Pi/PCr ratios in affected muscles.
Why the study?
Metabolic changes in lower leg skeletal muscles of patients with reflex sympathetic dystrophy were not well characterized using 31P NMR spectroscopy.
Does 31P NMR spectroscopy detect metabolic changes in the lower leg skeletal muscles of patients with reflex sympathetic dystrophy compared to unaffected muscles?
Observational (n=11)
Does 31P NMR spectroscopy detect metabolic changes in the lower leg skeletal muscles of patients with reflex sympathetic dystrophy compared to unaffected muscles?
31P NMR spectroscopy reveals impaired high energy phosphate metabolism in reflex sympathetic dystrophy, potentially due to cellular hypoxia or diminished oxygen utilization.

Supports 31P NMR spectroscopy evaluation in reflex sympathetic dystrophy; hypothesis-generating and should not yet change practice.
Heerschap et al. (1993) conducted an observational in Reflex sympathetic dystrophy (n=11). Reflex sympathetic dystrophy (affected legs) vs. Unaffected lower leg muscles of patients and volunteers was evaluated on Average tissue pH and inorganic phosphate/phosphocreatine ratio. Reflex sympathetic dystrophy was associated with a significant increase in average tissue pH and inorganic phosphate/phosphocreatine ratio in affected lower leg muscles.
