Selective Voluntary Motor Control (SVMC)

The ability to perform isolated joint movements

upon request, without using mass

flexor/extensor patterns and without undesired

movement at other joints, such as mirroring

Overview of SVMC

• Results from damage to the corticospinal tracts – pathwaysfor voluntary movement responsible for fine control

• Important for treatment planning and surgical decisionmaking

• While only assessed in patient’s with spastic CP, it has aseparate mechanism from spasticity

• Used as screening for selective posterior rhizotomy

Corticospinal Tracts

• Commonly injured in CP

• White matter damage of prematurity (e.g. PVL)

• Responsible for voluntary movement− Force

− Speed

− Timing

− Patternface

Tools

• Lower extremity – SCALE − Developed at UCLA (Fowler et al 2009)

− Hip, knee, ankle, subtalar joint, toes

• Upper extremity – TASC− Developed at Northwestern University

− Shoulder, elbow, forearm, wrist, fingers, thumb

• Both ask patient to perform selective movementtask

• Similar administration and scoring

Scoring

• SVMC at each joint is graded as:

− Normal = 2 points

− Unable/Absent = 0 points

− Impaired = anything else = 1 point

• SCALE 5 joints for a maximum of 10 points per limb

• TASC 8 movement patterns for a maximum of 16 points per limb

SCALE Validity and Reliability

• Content validity

• 14 expert clinicians

• Rated content, administration and grading

• Mean agreement 91.9%

• Recommendations incorporated into final tool

• Construct validity

• Interrater reliability

• Hip, knee, ankle, subtalar and toe motion

• Non-synergistic movement task

• Check available passive ROM

• Move within 3 second verbal count

• Move ONLY the joint being tested

• Grade best performance

Maximum score per each lower limb = 10

Grading

• Normal− Completes isolated movement within 3 seconds

• Unable− Does not move requested joint or

− Cannot perform movement out of synergy

• Impaired− Less than 50% available motion

− Slower than 3 second verbal count

− Mirror movements of contralateral limb

Grading Guidelines

• Only grade what you observe – no assumptions

• If contracture is present

− Grade movement that you see, not palpate

− Note contracture in descriptor section

− Area for comments
