Trunk Impairment Scale

Quantifies disability after stroke; also validated in Parkinson disease.

  • Starting position for each item is the same: 
    • The patient sits on the edge of a bed or table without back or arm support. 
    • Thighs are fully in contact with the surface.
    • Knees are bent at 90 degrees.
    • Feet are hip width apart and flat on the floor.
    • Arms are resting on the legs.
    • Head and trunk are in midline position.
    • If hypertonia is present, the position of the hemiplegic arm is taken as the starting position.
  • Tests are verbally explained to the patient and can be demonstrated if needed.
  • Each item can be performed 3 times; the highest score is recorded.
    • The patient can be corrected between the attempts.
    • No practice session is allowed.
  • If the patient scores 0 on the first item, the total score is 0.

Advice
  • Combine these results with other functional measures (e.g., gait assessments, functional independence scales) for a more comprehensive view of recovery.
  • Focus interventions on identified areas of deficit (e.g., trunk coordination, static balance, dynamic control).
  • Use results to track progress over time and update rehabilitation goals as patients improve.
