Spasticity/ToneSpasticity/Tone
• Spasticity is velocity related Spasticity is velocity related • Postural tone Postural tone • Mild to severe Mild to severe • Often co-exists with weaknessOften co-exists with weakness• More apparent in the lower extremities More apparent in the lower extremities

Weakness Weakness Management Management
• Primary weaknessPrimary weakness- Strengthening exercise to - Strengthening exercise to
maintainmaintain- Be aware of overuse- Be aware of overuse- May require compensatory - May require compensatory intervention (mobility aids, intervention (mobility aids, electrical stimulation, bracing, electrical stimulation, bracing,
etc.)etc.)
• Secondary weaknessSecondary weakness- Often overlooked- Often overlooked- May be minimized with early - May be minimized with early intervention intervention
- emphasize posture/stability- emphasize posture/stability- correct compensatory gait- correct compensatory gait- reduce lifestyle risk factors- reduce lifestyle risk factors- incorporate energy - incorporate energy management strategies management strategies

Treatment Considerations Lower Extremity FWS
Functional considerations •Gait/standing/transfers•Wheelchair/sitting posture to help
reduce extensor/flexor/adductor tone•Bed positioning to help reduce same•Driving: gassing/braking
Ankle/Foot• Weak dorsiflexion vs. strong, spastic plantar
flexion vs. extensor tone• Stretch ankle into dorsiflexion• Strengthen anterior tib with knee flexed• Strengthen anterior tib with knee in
extension• If a walker, consider rocker bottom shoe;
use the toe test• Consider extensor tone during gait on
ankle/knee/hip synergy• AFO to help prevent foot drop; consider
weight increase/influence on hip flexion; disuse atrophy
• FES of anterior tib; consider over stimulation/fatigue/spasticity; disuse atrophy
Knee• Quadriceps/hamstring strength/spasticity
inequities vs. extensor/flexor tone•Stretch and strengthen both•Consider stretch of antagonist prior to
strengthening agonist •Position to reduce tone •When strengthening use a circuit of
alternating between knee extension and knee flexion
Hip
• Hip flexor/extensor imbalance– Stretch and strengthen– Positioning/posture considerations
• Hip abductor/adductor imbalance– Stretch and strengthen– Positioning/posture considerations
• Trunk instability/“core” weakness– Get “on the ball”– Pilates concepts
Other Considerations
• Asymmetry of weakness/spasticity • Increased work of mobility with gait
aids; cane, crutches, walkers• Wheelchair use• Other MS symptoms - pain, tremor,
sensory dysfunction, central ataxia, cognitive dysfunction, emotional dysfunction
• Other diseases: Cardiopulmonary/vascular, arthritis, etc
Conclusions
• Fatigue, weakness and spasticity (FWS) are common symptoms of MS
• FWS are manageable through physical and medical interventions
• Self-management of FWS is challenging and requires effort, consistency and support
