While relapsing fever is generally in decline, or is at least limited to a few endemic areas, Lyme disease appears to be rapidly spreading across the globe. The geographical spread coincides with the inception of a variety of new reservoirs and vectors, which is in turn initiating the evolution of new Lyme disease-causing Borrelia species. Corresponding with the incidences of each disease and the impact on public health is the fact that only a modest amount of research is being done with respect to treatment and diagnosis of relapsing fever, whereas Lyme disease research is burgeoning. Despite the volume of study being conducted on Lyme disease, both clinical and laboratory diagnosis are far from perfect. The multitude of different symptoms presented, combined with the variety of emerging strains, complicates diagnoses. Neither clinical findings nor serological or molecular laboratory diagnosis is able to detect all forms of disease. Established serological tests are often challenged by conflicting clinical findings, and molecular testing, while often specific, has yet to be standardized, despite being in use for the past 15 years. Because of the changing face of this disease and its causative agent, it is likely that an accurate and sensitive laboratory diagnosis will always be elusive, and it will take a combination of both serology and molecular detection techniques to provide the greatest chance for success.

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
