Which statement best describes the primary purpose of the SCALE and SCUES scales?

• A. They quantify the ability to perform isolated movements.
• B. They measure gait speed.
• C. They assess balance during standing.
• D. They evaluate participation.

Answer: (A)

Selective motor control is the ability to move one joint or muscle group independently from others. SCALE and SCUES are designed to quantify exactly that in cerebral palsy, by assessing how well a person can perform isolated joint movements in the lower and upper extremities, respectively. They score dissociated movement, highlighting how much unintended movement or cross-activation occurs when a single joint is asked to move. This impairment-focused measure helps gauge the level of motor control impairment and track changes over time or with intervention. These scales are not about functional performance like walking speed, standing balance, or participation in daily life. Gait speed and balance tests measure how well someone moves or maintains posture in tasks, while participation measures look at involvement in activities. SCALE and SCUES stay at the level of motor impairment, describing how selectively a person can recruit muscles and coordinate joints during isolated movements.
