Objectives:
To investigate how Goal Attainment Scale (GAS) in spinal muscular atrophy (SMA) identifies patient-reported clinically meaningful improvement after disease-modifying treatment and to evaluate whether the patient-stated goals identified through GAS are already captured by items in existing motor assessment scales.
Design:
Longitudinal retrospective study considering the first available follow-up.
Setting:
The study was conducted in a rehabilitation center dedicated to neuromuscular diseases.
Participants:
The GAS was recorded from N=58 SMA patients on treatment with nusinersen or risdiplam regularly followed for clinical follow-up in 2023.
Main Outcome Measures:
Clinical and demographic data, SMA type, Hammersmith Functional Motor Scale, Children's Hospital of Philadelphia scale, Revised Upper Limb Module, 6 Minute Walk Test, and GAS questionnaire were collected.
Results:
One hundred forty-nine SMART goals were clustered in 15 macrodomains, with the most frequent being mobility, upper limb strength, and activities of daily living. Most smart goals (72%) could be redirected to items of standardized motor and functional scales. Unmet goals primarily involved activities of daily living, endurance, and mobility, with a particular focus on upper limb strength.
Conclusions:
The GAS provides an individualized, reliable, and quantifiable measure of goal attainment, and is useful in setting realistic treatment expectations that could guide patients and physicians to interpret changes over time.

01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
