AI Answers About Frozen Shoulder: Model Comparison

Frozen shoulder (adhesive capsulitis) affects ~2-5% of the general population and up to ~20% of people with diabetes. The condition involves progressive stiffening and pain of the shoulder joint, severely restricting range of motion. It typically progresses through three stages: the freezing phase (increasing pain and stiffness over 2-9 months), the frozen phase (less pain but severe stiffness lasting 4-12 months), and the thawing phase (gradual return of motion over 5-24 months). Women aged 40-60 are most commonly affected. The prolonged duration and significant functional limitation drive people to search online for treatment options and timeline expectations.
The Question We Asked
“Over the past three months, my right shoulder has been getting progressively stiffer. I can barely raise my arm above shoulder height now, and reaching behind my back is nearly impossible. The pain was bad at first but now it’s more about the stiffness. I’m 52 and have type 2 diabetes. My doctor thinks it’s frozen shoulder. How long will this last? Is there anything that can speed it up?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 correctly described the three stages of frozen shoulder and provided realistic timeline expectations. It mentioned that diabetes is a significant risk factor associated with more severe and prolonged cases. It discussed treatment options including physical therapy, corticosteroid injections, and hydrodilatation, and correctly noted that most cases eventually resolve, though full recovery can take one to three years.
Claude 3.5
Strengths: Claude delivered the most comprehensive and honest response, correctly noting that frozen shoulder in diabetic patients tends to be more severe, more bilateral, and more resistant to treatment than in non-diabetic patients. It explained that while the condition is self-limiting, “self-limiting” does not mean short. It provided the most detailed treatment discussion including guided physical therapy, corticosteroid injections, manipulation under anesthesia, and arthroscopic capsular release for refractory cases.
Gemini
Strengths: Gemini offered practical daily adaptation strategies for living with restricted shoulder movement, including using a reacher tool, adjusting car mirror positions, and modifying dressing techniques. It emphasized the importance of gentle stretching within pain tolerance.
Med-PaLM 2
Strengths: Med-PaLM 2 provided a thorough evidence-based review of treatment outcomes, noting that corticosteroid injections provide the most benefit during the freezing phase and that physical therapy should focus on gentle stretching rather than aggressive mobilization. It discussed the role of suprascapular nerve blocks for pain management.
What Each Model Got Wrong or Missed
GPT-4
- Did not specifically address the worse prognosis in diabetic patients
- Failed to discuss when more aggressive interventions should be considered
- Could have mentioned the risk of developing frozen shoulder in the opposite shoulder
Claude 3.5
- Did not provide enough practical daily coping strategies
- Could have discussed home exercise programs in more specific detail
Gemini
- Did not adequately explain the three-stage progression or provide realistic timelines
- Oversimplified treatment by focusing mainly on stretching without discussing medical interventions
- Failed to discuss the diabetes connection and its impact on prognosis
Med-PaLM 2
- Too clinical for a patient struggling with a frustrating chronic condition
- Did not address the emotional frustration of such a prolonged condition
- Lacked practical lifestyle adaptation advice
Red Flags All Models Should Mention
While frozen shoulder is typically self-limiting, certain situations need attention:
- Severe pain that is not improving or worsening beyond the expected freezing phase — may indicate a different diagnosis
- Symptoms following a fall or injury — may be rotator cuff tear or fracture rather than adhesive capsulitis
- Weakness in addition to stiffness — suggests possible rotator cuff pathology
- Bilateral frozen shoulder developing simultaneously — warrants investigation for underlying conditions
- Fever or night sweats with shoulder symptoms — infection or other systemic cause should be excluded
- No improvement after 12-18 months — may warrant more aggressive intervention or reassessment of diagnosis
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding the three stages and natural history of frozen shoulder
- Learning about the relationship between diabetes and frozen shoulder
- Getting general information about treatment options and their timing
- Learning practical strategies for living with restricted shoulder movement
- Understanding that the condition is self-limiting, even if prolonged
See a Doctor When:
- You suspect frozen shoulder (diagnosis confirmation and baseline assessment is important)
- You have diabetes and develop shoulder stiffness (more aggressive early treatment may help)
- You want corticosteroid injections for pain management during the freezing phase
- You need a referral for guided physical therapy
- The condition is not improving after the expected timeline
- You want to discuss surgical options for refractory frozen shoulder
- Symptoms appeared after an injury or are accompanied by weakness
Methodology
Each AI model received the identical patient scenario prompt. Responses were evaluated by the mdtalks editorial team using our standardized evaluation framework, which assesses factual accuracy against current orthopedic and rehabilitation guidelines, completeness of safety warnings, readability for a general audience, and appropriateness of the recommendation to seek professional care. Scores reflect composite ratings across these dimensions.
Key Takeaways
- Claude 3.5 scored highest (8.8) for its honest discussion of the diabetes-related prognosis and comprehensive treatment overview
- Frozen shoulder in diabetic patients is typically more severe and longer-lasting than in the general population
- The condition is self-limiting but can take one to three years for full recovery
- Early intervention with corticosteroid injections during the freezing phase provides the most benefit
- Gemini scored lowest (7.2) due to oversimplification and failure to address the diabetes connection
