Pharmacological and SurgicalProcedures for the Treatment of Spasticity Luigi Piccinini M.D., PM&R ScientificInstitute «Medea» Bosisio Parini (LC) Italy
SpasticityReduction vs Function • Spasticity = pathologicalfactor • Spasticity = tool for function • Spasticity + MuscleWeakness
«May the force be with you» (Starwars) • Considermusclestrength and weakness (Piccinini)
Aims of Treatment • Painreduction • Functionalimprovements • Facilitate use of orthosis • Preventsecondaryproblems (muscle & bone deformities) (Early Treatment) • Facilitate nursing and caring
Treatment Options General SDR Oraldrugs ITB Reversible Not reversibile BTX Surgery Focal
OralDrugs • Diffusedspasticity • Mild/moderate Spasticity • Too young for otheroptions
Side Effects • Sedation • Sleepiness • Increasedsialorrhea • Excessivehypotonia • Hypotension
Baclofen (Lioresal) • 5 mgs/day • Increasedosage of 5 mgseach 3-4 days • Maxdosage: ???
BotulinumToxin • Identifyfunctionalproblem • Measureit • Intervention • Outcomemeasurement • Maintainimprovement
BotulinumToxin • Safe • No anaphylacticreactionsreported • Avoid use duringpregnancy
BotulinumToxin • Botox • Dysport • Xeomin • ………
BotulinumToxinDilution • 1 cc • 2 cc • 5 cc • ………………. • Reduced or increaseddiffusion
Primary Non- Responders • Musclefixedcontractures • Subclinicpreviousbotulism • USA Armyimmunization
Secondary Non-Responders • Antibodies in 5-10% pts
AdverseEvents BoNtA Placebo • > Falls 9,3% 3% • Pain 2,3% / • Local weakness 2,3% / • General weakness 1% /
Therapeuticaleffect • Begins in 3-4 days • Maxeffect: 2-3 weeks • Duration: 3-6 months
Action 2 3 1 4 5 Adapted from: dePaiva et al. PNAS 1999, 96:3200
Repeat treatment • Samemuscles: 3 months • Differentmuscles: 1 month
Until……… • Musclefixedcontracture • Antibodies
InjectionTechniques • Free? • EMG guided? • CT guided? • US guided ?
Sedation • Midazolam? • EMLA? • Spray Ice? • ???
CombinedTherapies • BoNtA + PT • BoNtA + orthosis • BoNtA + casting /serial casting
Casting / Serial Casting • 1 week afterinjection • Removeafter 2 weeks • Possible re-casting with increaseddorsiflexion • Afterremoving, orthosis + PT
Results • OxygenConsumption • HR • Endurance • Improvement of kinetic and kinematicparameters
ITB Advantages • Reduced side effects • Reducedeffective dose compared to oraldrug • Telemetricprogramming
ITB: Effects • Improvement of ADLs • Improvedcompliance for PT • Reduce pain • Sleepimproving
ITB Management • Bolus test • Goodresponsepumpimplantation • Progressive dose increaseuntiloptimaleffect • Effectmonitoring • Refill
ITB Advantages • High concentration in CSF • Reduced side effects • Reducedspasticityonlyduring the day • Increasedwalkingability • Increasedcomplianceduring PT • Reducedpain • Reversibility
ITB Disadvantages • Surgery • Management difficulty • Periodicsurgery • Complications
RelationshipOrthopaedicIssues/SpasticityTreatment • Givepriority to primaryproblems • Correctlaterorthopaedicdeformities • Youcouldavoidorthopaedicsurgery
Post- Surgery • Rehabilitation Center • Progressive increase of drug flow (20%/day) • Complicationsmonitoring • Posturalassessment • Evaluation for assistivedevices and/or orthosis • Encourage the achievement of new motor pattern
Complications • Infectionsremove • CatheterkinkingXRaysurgery • CathetercollapseXRaysurgery • Leaking
Removal Management • Gradual flow reduction (20%/day) • Oraldrugs • Pumpswitch-off / pumpremoval
Rhyzotomy • No experience in HSP (only CP) • Notreversible
OrthopaedicSurgery • Notspecific for spasticity • Secondaryproblems
Aims of Treatment • Rule # 1: choose THAT treatment for THAT spasticity in THATpatient
