About

This is a two-stage pathway that streamlines the delivery, reminders, scoring, analysis, and data export of the Patient Specific Functional Scale (PSFS ) PROM for clinicians and researchers.

This pathway is designed to enable clinicians and researchers to

  • deliver the PSFS PROM tool to their patients quickly and easily,
  • provide patients with contextual information about the tool,
  • automatically remind patients to submit the PSFS PROM,
  • collect the results of the submitted PSFS PROM,
  • calculate the PSFS PROM Score based on the answers submitted,
  • allocate PSFS PROM Cut Points based on the score calculations,
  • display survey results, Score and Cut Points, and
  • provide an export of deidentified PSFS PROM data for research purposes.
Intended Population

Adults with musculoskeletal disorders (back, neck, knee, upper extremity), stroke rehabilitation, and some non-musculoskeletal populations.

Method of use

The Patient-Specific Functional Scale (PSFS) is administered through a structured patient-centred process to identify and track functional limitations.

PROM details
PROMs included
  • Patient Specific Functional Scale (PSFS)
Description

Patient-specific questionnaire where patients identify & rate difficulty of 3-5 functional activities (0-10 scale). Measures activity limitations in musculoskeletal/neurological conditions.

Type

Evaluative (monitors functional changes over time)

Advantages
  • Patient-centered goals
  • Quick administration (<5 mins)
  • Flexible across conditions
  • High clinical responsiveness
Disadvantages
  • Requires patient engagement to identify activities
  • Not standardized for direct comparisons
  • Less validated in non-musculoskeletal populations
Evidence

Strong validity/reliability in musculoskeletal populations. Emerging evidence for stroke & community-dwelling older adults.

Reliability

ICC 0.82 (cervical radiculopathy), 0.71-0.90 (upper extremity). MDC 2.0-2.8 points.

Reference population

Adults with chronic pain, post-surgical rehabilitation, neurological conditions (stroke).

Scoring

Average score of 3-5 self-identified activities (0=unable to perform, 10=no difficulty). PSFS 2.0 (2024 update) uses inverted 0-10 scoring (0=no difficulty) with improved responsiveness

Cut Points
  • MDC: 2.0-2.8 points
  • MCID: 2.0 points (musculoskeletal)
  • Threshold for “meaningful change”: ≥3.3 points
