HOW WE REVIEW EVIDENCE
Read beyond the conclusion.
Every review should help the reader judge relevance, limitations and practical meaning—not simply report whether a result was statistically significant.
How trustworthy is the design?
Study type, allocation, masking, attrition, confounding and risk of bias.
How large and precise was the effect?
Absolute change, uncertainty, clinical importance and adverse events.
Does it apply to this patient?
Setting, eligibility, presentation, comorbidity, intervention dose and feasibility.
How does it fit the wider evidence?
Consistency with guidelines, reviews, previous trials and plausible alternatives.
What should change—if anything?
Practical interpretation, residual uncertainty and questions for shared decisions.

Substantial clinician-facing reviews covering diagnosis, rehabilitation, injections, procedures, prognosis and guideline implementation.
Frozen shoulder guidelines: recommendations, certainty and implementation
CLINICAL EVIDENCE REVIEW · GUIDELINES Guidelines translate research, clinical expertise, patient priorities and health-system constraints into recommendations. They can improve consistency, but they do not remove uncertainty, replace clinical reasoning or guarantee that one pathway transfers unchanged to every patient, profession and country. Evidence in...
Natural history, risk factors and recovery
CLINICAL EVIDENCE REVIEW · PROGNOSIS Frozen shoulder often improves substantially, but “self-limiting” is an incomplete prognosis. Recovery is variable, pain and function do not change on the same timetable, and some people retain measurable stiffness or disability for years. Evidence in briefTraditional freezing, frozen and...
Manipulation, capsular release and post-procedure care
Manipulation under anaesthesia and arthroscopic capsular release are options for selected patients whose disability remains unacceptable after an appropriate non-operative pathway. Neither should be presented as an inevitable next stage of frozen shoulder. Evidence in briefThe 503-participant UK FROST trial found no clinically important superiority...
Corticosteroid injection and hydrodilatation
CLINICAL EVIDENCE REVIEW · INJECTIONS Injection decisions in frozen shoulder should begin with the problem being treated. Corticosteroid injection is principally an option for reducing pain and improving function in the shorter term; hydrodilatation adds capsular distension, but the size and clinical importance of that...
Exercise, manual therapy and rehabilitation dosage
CLINICAL EVIDENCE REVIEW · REHABILITATION Rehabilitation for frozen shoulder is not a standard sequence of stretches. It is a continuing dosage decision: select movement and loading that address the person’s priorities, deliver enough stimulus to support adaptation, and avoid a symptom response that repeatedly removes...
Clinical assessment, imaging and differential diagnosis
CLINICAL EVIDENCE REVIEW · DIAGNOSIS Frozen shoulder remains primarily a clinical diagnosis. The difficult part is not recognising a very typical presentation; it is deciding how much uncertainty remains, identifying conditions that can imitate or coexist with capsular stiffness, and using imaging only when it...

CRITICAL READING
Questions to take into every paper.
A compact appraisal prompt for clinicians reading beyond our summaries.
01
Was the study design suitable for the question?
02
Were participants comparable to the people in your setting?
03
Were intervention and comparator doses described well enough to reproduce?
04
Were outcomes important to patients and measured at useful time points?
05
How precise, clinically meaningful and complete were the results?
06
What bias, conflict, attrition or selective reporting could alter interpretation?
07
Were adverse events and treatment burden captured adequately?
08
Does the finding justify changing practice—or only changing certainty?
EDITORIAL STANDARD
Transparent about evidence—and uncertainty.
Reviews distinguish study findings from editorial interpretation, link to the original source wherever possible and identify important limitations or conflicts.
Content is educational, periodically reviewed and corrected when necessary. It does not replace full-text appraisal, local guidance, individual assessment or professional judgement.
