Physical assessments for infantile-onset SMA

Motor milestones 

The Hammersmith Infant Neurological Examination (HINE) Section 2

The HINE Section 2 measures changes in key developmental motor milestones in infants and weaker children with SMA. Results are measured on a point system used to score improvement or worsening in motor milestone achievement.

8 motor milestones scored:

Assessment criteria

Motor function 

The Children’s Hospital of Philadelphia Infant Test of Neurological Disorders (CHOP INTEND)

The CHOP INTEND measures incremental motor function changes such as increased movement, flexibility and strength.

16 motor functions scored within 4 categories:

Motor function 

The Hammersmith Functional Motor Scale – Expanded (HFMSE)

The HFMSE measures motor function changes in a broad range of ambulatory and nonambulatory individuals. An increase of ≥2 points is typically considered a clinically meaningful improvement.

This assessment should be performed by a physical therapist or trained HCP.

33 functions scored using 7 categories:

Assessment criteria

Walking ability 

The 6-Minute Walk Test (6MWT)

The 6MWT is a dynamic exercise assessment that measures fatigue-related changes in walking ability. Participants are instructed to walk as fast as possible along a 25-meter course, turn around, and return in the opposite direction. The course is repeated as often as possible for 6 minutes. Running or jogging is not permitted.

Assessment criteria

Upper limb function 

The Revised Upper Limb Module (RULM)

The RULM is an updated version of the Upper Limb Module (ULM) assessment. It includes more activities related to daily life such as lifting heavier objects. The RULM measures upper limb strength in most individuals with SMA while the ULM is typically for weaker, nonambulatory individuals with SMA.
