What is a PICO Question in Physical Therapy?
Before diving into examples, it’s important to clarify what a PICO question entails within the context of physical therapy.
Definition of PICO
- Population (P): The specific group of patients or individuals being studied.
- Intervention (I): The treatment, therapy, or intervention being considered.
- Comparison (C): The alternative to the intervention, such as a placebo, different therapy, or no treatment.
- Outcome (O): The measurable result or effect of the intervention.
Importance of PICO in Physical Therapy
Utilizing PICO questions ensures:
- Focused literature searches
- Clear clinical decision-making
- Evidence-based practice
- Improved patient outcomes

Popular PICO Question Examples in Physical Therapy
This section presents curated examples demonstrating how to formulate PICO questions across different scenarios in physical therapy practice.
1. PICO Questions for Managing Low Back Pain
Low back pain is a common reason for physical therapy referrals. Here are examples illustrating different research questions:
Example 1: Effectiveness of Manual Therapy
- P: Adults with chronic non-specific low back pain
- I: Manual therapy combined with exercise
- C: Exercise alone
- O: Reduction in pain and disability
Formulated PICO:
In adults with chronic non-specific low back pain, does manual therapy combined with exercise, compared to exercise alone, result in greater reductions in pain and disability?
Example 2: Comparing Modalities
- P: Patients with acute low back strain
- I: Ultrasound therapy
- C: Rest and analgesics
- O: Time to return to work
Formulated PICO:
In patients with acute low back strain, does ultrasound therapy, compared to rest and analgesics, decrease time to return to work?

2. PICO Questions for Postoperative Rehabilitation
Post-surgical patients often require tailored physical therapy programs. Here are relevant PICO questions:
Example 1: Early vs. Delayed Mobilization after Knee Arthroplasty
- P: Patients post-total knee arthroplasty
- I: Early mobilization within 24 hours
- C: Delayed mobilization after 72 hours
- O: Range of motion and functional mobility
Formulated PICO:
In patients after total knee arthroplasty, does early mobilization within 24 hours, compared to delayed mobilization after 72 hours, improve range of motion and functional mobility?
Example 2: Use of Neuromuscular Electrical Stimulation (NMES)
- P: Post-ACL reconstruction patients
- I: NMES combined with traditional physical therapy
- C: Traditional physical therapy alone
- O: Quadriceps strength and knee stability
Formulated PICO:
In patients following ACL reconstruction, does adding neuromuscular electrical stimulation to traditional physical therapy improve quadriceps strength and knee stability compared to traditional therapy alone?

3. PICO Questions for Sports Injury Rehabilitation
Physical therapists working with athletes often focus on returning to play safely and efficiently.
Example 1: Balance Training for Ankle Sprains
- P: Athletes with lateral ankle sprains
- I: Balance training exercises
- C: Standard rehabilitation without balance training
- O: Time to return to sport and re-injury rates
Formulated PICO:
In athletes with lateral ankle sprains, does incorporating balance training into rehabilitation, compared to standard therapy without balance exercises, reduce time to return to sport and re-injury rates?
Example 2: Effects of Plyometric Exercises
- P: Youth soccer players recovering from hamstring strain
- I: Plyometric training during rehab
- C: Conventional strengthening exercises
- O: Return-to-play time and reinjury incidence
Formulated PICO:
In youth soccer players recovering from hamstring strain, does plyometric training during rehabilitation, compared to conventional strengthening exercises, decrease return-to-play time and reinjury rates?

4. PICO Questions for Chronic Conditions Managed with Physical Therapy
Chronic conditions like osteoarthritis or fibromyalgia often require long-term management strategies.
Example 1: Exercise Modalities for Osteoarthritis
- P: Elderly patients with knee osteoarthritis
- I: Aquatic exercise
- C: Land-based exercise
- O: Pain reduction and improved mobility
Formulated PICO:
In elderly patients with knee osteoarthritis, does aquatic exercise, compared to land-based exercise, lead to greater pain reduction and improved mobility?
Example 2: Education vs. Exercise Alone in Fibromyalgia
- P: Adults with fibromyalgia
- I: Patient education combined with physical activity
- C: Physical activity alone
- O: Fatigue levels and quality of life
Formulated PICO:
In adults with fibromyalgia, does combining patient education with physical activity, compared to physical activity alone, improve fatigue levels and quality of life?

How to Create Your Own PICO Questions in Physical Therapy
Developing effective PICO questions involves a systematic approach:
Step-by-Step Guide
1. Identify the Clinical Issue: What problem are you addressing?
2. Define the Population: Who are your patients? Consider age, condition, severity.
3. Determine Interventions: What treatments or therapies are you comparing?
4. Select Comparators: What is the alternative or control?
5. Decide on Outcomes: What results matter most? Pain reduction, function, mobility, quality of life?
6. Formulate the Question: Combine these elements into a clear, concise question.
Tips for Effective PICO Questions
- Be specific with patient characteristics.
- Use measurable outcomes.
- Ensure the comparison is relevant.
- Focus on clinically significant results.

Utilizing PICO Questions to Enhance Evidence-Based Practice
Once formulated, PICO questions serve as the foundation for literature searches, guiding clinicians to relevant research studies, systematic reviews, and clinical guidelines.
Benefits of Using PICO in Physical Therapy
- Streamlines the research process
- Ensures focused and relevant evidence gathering
- Supports shared decision-making with patients
- Facilitates critical appraisal of literature

Resources for Finding Evidence Based on PICO Questions
Physical therapists can utilize multiple tools and databases to find evidence aligned with their PICO questions:
- PubMed/MEDLINE: For peer-reviewed articles
- Cochrane Library: For systematic reviews
- PEDro (Physiotherapy Evidence Database): Specifically for physiotherapy research
- Google Scholar: For broader searches
