Outpatient Physical Therapy Improvement in Movement Assessment Log

Last Updated

Purpose

APTA's Outpatient Physical Therapy Improvement in Movement Assessment Log (OPTIMAL) is an instrument that measures difficulty and self-confidence in performing 22 movements that a patient/client needs to accomplish in order to do various functional activities. OPTIMAL 1.1 has been updated from the original version to increase clinical utility. This includes adding the clinically relevant item of standing and providing changes to scoring instructions to increase clinical utility. These changes will assist patient and physical therapist discussion toward identifying the primary goal for the episode of care.

Key Descriptions

  • The Outpatient Physical Therapy Improvement in Movement Assessment Log (OPTIMAL) is an instrument that measures difficulty and self-confidence in performing 22 movements that a patient/client needs to accomplish in order to do various functional activities.
  • Scoring is relatively simple, and it can be done in 3 different ways:
  • 1) The most expedient way to calculate a total score is to sum the responses (marked on a 1 to 5 scale) across all 22 items on difficulty and on self-confidence upon both the patient’s/client’s admission (baseline) and discharge from physical therapy (final). Then subtract the final sum from the baseline sum. The higher the change score, the more the patient has improved. If a particular item on the OPTIMAL is marked as "Not Applicable," then this item should be dropped completely from the overall scoring. For example, suppose that two items are marked "Not Applicable." The best possible score on "Difficulty" or "Self-confidence" for this patient would be "20" (1 x 20 items) and the worst possible score would be "100" (5 x 20 items). Do not add "9" to the score ("9" is an arbitrary coding convention to distinguish the item from missing data if you are entering information into a database).
  • 2) The instrument includes a question that asks the patient/client, “From the above list [referring to the 22 items], choose the 3 activities you would most like to be able to do without any difficulty,” which may also provide clinically meaningful information. The therapist can calculate a specific item score to appraise the changes between admission and discharge scores on these three items.
  • 3) Finally, The instrument includes a question that asks the patient/client, “From the above list of 3 activities please indicate the primary activity that you would most like to be able to do without any difficulty,” which may also provide clinically meaningful information. The therapist can calculate a specific item score to appraise the changes between admission and discharge scores on the primary goal. This scoring method allows the therapist to determine the outcome of treatment on the ability to perform the movement that is most important to the patient/client. This method particularly aids in the clinical decision-making process.

Professional Association Recommendation

Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Criterion Validity (Predictive/Concurrent)

Musculoskeletal Diagnoses:

(Guccione et al. 2005) 

  • Baseline Difficulty Scale scores had strong correlations with PF-10 (physical function subscale of the SF-36) scores (-0.80) and moderate correlations with Visual Analogue Scale (VAS) scores for overall difficulty (-0.65) 
  • The baseline Confidence Scale scores had strong correlations with PF-10 scores (-0.72) and moderate correlations with VAS scores for overall confidence (-0.60)

Construct Validity

Musculoskeletal Diagnoses:

(Guccione et al. 2005) 

The Cronbach alphas for the subscales of the Difficulty Scale at 2- and 4-week follow-ups, respectively, were: 

  • Trunk (0.82, 0.87)
  • Lower extremity (0.95, 0.96)
  • Upper extremity (0.93, 0.94)

For the subscales of the Confidence Scale, the Cronbach alphas for the 2- and 4-week follow-ups, respectively, were: 

  • Trunk (0.87, 0.87)
  • Lower extremity (0.95, 0.95) 
  • Upper extremity (0.94, 0.95)

Floor/Ceiling Effects

Musculoskeletal Diagnoses:

(Guccione et al. 2005) 

There were minimal to moderate ceiling effects for some items on the OPTIMAL.

Responsiveness

Musculoskeletal Diagnoses:

(Guccione et al. 2005) 

  • 4 of the 6 subscales had medium effect sizes from 0.21 - 0.44 at the 4 week follow up, this time frame was the most sensitive to change. 
  • The upper extremity subscale of the Difficulty scale had a small effect size and the upper extremity subscale of the Confidence scale had a negative effect size, which indicates participants became less confident with mobility over time.
