The<unk>  of<unk> <unk> s per muscle can change due to aging, disease, or injury. These techniques are used to diagnose disease or monitor the effects of aging, disease and injury over time. In neuropathies,<unk> eurons die off, reducing the<unk>  of<unk> <unk> s progressively. In myopathies the size of the<unk> <unk> s is reduced because of the death of<unk>  fibres, but the<unk>  of<unk> <unk> s remains the same until the disease progresses to a very severe state. In collaboration with other electromyography techniques, these conditions can be diagnosed and monitored. In a similar vein, normal aging also reduces the<unk>  of<unk> <unk> s but not to the same degree as disease. The effects of injury depend on the circumstances.
