Leeds Adult Spasticity Impact Scale (LASIS)

Purpose of the measure

The Leeds Adult Spasticity Impact Scale (LASIS) is a measure of passive arm function that is administered by semi-structured interview to the patient or carer. It consists of 12 items of low difficulty that evaluate performance of daily functional tasks in the individual’s normal environment. The LASIS is useful for patients with minimal or no active movement or function but with self-care issues of the upper extremity (Ashford et al., 2008).

Available versions

The LASIS was originally published as the Patient Disability and Carer Burden Scale by Bhakta et al. (1996), which included 8 patient items and 4 carer items (Bhakta et al., 2000). The four carer items have been excluded from the current version of the LASIS.

Features of the measure

The LASIS consists of 12 items that measure passive and low-level active function.

Passive function items:

  • 1 Cleaning the palm (affected hand)*
  • Cutting fingernails (affected hand)*
  • Cleaning the affected elbow*
  • Cleaning the affected armpit*
  • Cleaning the unaffected elbow*
  • Putting arm through coat sleeve*
  • Difficulty putting on a glove
  • Difficulty rolling over in bed
  • Doing physiotherapy exercises to arm*

Active function items:

  • Difficulty balancing in standing*
  • Difficulty balancing when walking*
  • Hold object steady, use other hand (jar)

* Items originally included in the Patient Disability and Carer Burden Rating Scale (Bhakta et al., 2000).

Items are rated between 0 – 4 according to the following criteria:

0 = No difficulty
1 = Little difficulty
2 = Moderate difficulty
3 = A great deal of difficulty
4 = Inability to perform the activity

The total score is calculated as the sum of individual scores, divided by the total number of questions answered. This results in a total score between 0 – 4 that represent disability or carer burden (Ashford et al., 2008).
Note: As the final score does not rely on responses to all 12 items, it may not reflect actual disability or function in the arm (Ashford et al., 2008).

Description of tasks:
The LASIS is administered through semi-structured interview with the patient or carer, with regard to the patient’s performance of tasks over the past 7 days.

The LASIS takes approximately 10 minutes to administer (Ashford et al., 2008).

Training requirements:
The LASIS should be administered by a clinician (Ashford et al., 2008).

Equipment such as a jar may be required to validate responses.
