In the last two decades, the availability of new
disease-modifying therapies has radically changed the management of
multiple sclerosis (MS) and relapsing–remitting MS in particular (1), resulting in a longer life expectancy for patients with the disease (2).
Nevertheless, MS currently remains incurable and, in most patients,
disability will eventually progress and they must live with the very
many symptoms associated with the disease. These symptoms can have a
major impact on patient's quality of life (3)
and their management is considered important, although traditionally,
this area has received far less attention than disease-modifying
therapies (4).
A wide range of treatments are available to manage each of the MS symptoms (5–7).
Given that different agents are used for different symptoms and a
patient may have several symptoms present at the same time, many MS
patients are multi-medicated, particularly as most patients will also be
receiving disease-modifying therapies. This article will assess the
current fragmented approaches to pharmacological management of
spasticity muscle tone increase-related symptoms and their shortcomings.
Given that the treatment of MS-associated muscle spasticity has been
associated in a good number of clinical trials and also observational
studies with the improvement of several other functions/symptoms present
in MS (8),
we will conceptualize, and subsequently hypothesize, about the clinical
interest of introducing the more broad concept of “Spasticity-Plus
Syndrome” to provide a unified framework for managing all these
seemingly related functions/symptoms. By applying such a concept, it
would be possible to simplify the management of symptoms associated with
MS and reduce importantly the interactions and adverse effects
associated with poly-medication.
