Hauser Ambulation Index

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Introd­uction

The AI is a rating scale developed by Hauser et al (1983) to assess mobility by evaluating the time and degree of assistance required to walk 25 feet. Scores range from 0 (asymp­tomatic and fully active) to 10 (bedri­dden). The patient is asked to walk a marked 25-foot course as quickly and safely as possible. The examiner records the time and type of assistance (e.g., cane, walker, crutches) needed.

Hauser Ambulation Index

0 = Asympt­omatic; fully active.
1 = Walks normally, but reports fatigue that interferes with athletic or other demanding activi­ties.
2 = Abnormal gait or episodic imbalance; gait disorder is noticed by family and friends; able to walk 25 feet (8 meters) in 10 seconds or less.
3 = Walks indepe­nde­ntly; able to walk 25 feet in 20 seconds or less.
4 = Requires unilateral support (cane or single crutch) to walk; walks 25 feet in 20 seconds or less.
5 = Requires bilateral support (canes, crutches, or walker) and walks 25 feet in 20 seconds or less; or requires unilateral support but needs more than 20 seconds to walk 25 feet.
6 = Requires bilateral support and more than 20 seconds to walk 25 feet; may use wheelc­hair* on occasion.
7 = Walking limited to several steps with bilateral support; unable to walk 25 feet; may use wheelc­hair* for most activi­ties.
8 = Restricted to wheelc­hair; able to transfer self indepe­nde­ntly.
9 = Restricted to wheelc­hair; unable to transfer self indepe­nde­ntly.
*The use of a wheelchair may be determined by lifestyle and motiva­tion. It is expected that patients in Grade 7 will use a wheelchair more frequently then those in Grades 5 or 6. Assignment of a grade in the range of 5 to 7, however, is determined by the patient’s ability to walk a given distance, and not by the extent to which the patient uses a wheelc­hair.
