Abstract:
Hermann Oppenheim described the 'Useless Hand' in 1911 as a classical but uncommon presentation of multiple sclerosis, in which a hand loses useful function due to proprioceptive loss, with relatively preserved motor function. Light touch perception may be subjectively altered or can be relatively intact. The lesion is (usually) a demyelinating plaque in the posterior columns of the cervical spinal cord. Depending on its location, it may affect one limb, or if more central, may produce a bilateral (if asymmetrical) picture. This article reviews a clinical case, historical background, pathophysiology as well as examination tips to aid its recognition.

The Nernst Equation
The interconnection between standard cell potentials and various thermodynamic parameters such as the standard free energy change ΔG° and equilibrium constant K has been previously explored. For example, a redox reaction involving zinc(II) and tin(II) ions at 1 M concentration with Eºcell = +0.291 V and ΔG° = −56.2 kJ is spontaneous.
