Qualitative analysis of Achilles tendon rupture

Evidano7 min read

Evidano is an AI-powered qualitative data analysis platform that transcribes interviews, assists AI-assisted coding, and secures sensitive clinical research data. Researchers and clinical teams reading the June 29, 2026 PLoS One qualitative study (n=15) will find clear, replicable signals about non-surgical Achilles tendon rupture recovery, varied injury presentation, boot-management friction, and a persistent fear of re-rupture that shapes rehab behaviour. This post shows how to turn those interview transcripts into decision-ready evidence using AI-enabled qualitative analysis. You can run a concise workflow in minutes on Evidano, and apply concrete coding and visualization ideas (theme frequency, co-occurrence maps, cross-segment comparisons) to make findings actionable for physiotherapy services, trial designers, and patient-facing teams. Read on for a snapshot of the study, practical implications for qualitative analysis of Achilles tendon rupture, and an Evidano-ready checklist to reproduce and scale the study’s insights while keeping data private and research-grade.

Key Takeaways

The PLoS One study (Published: June 29, 2026) found that early messaging, boot self-management burden, and fear of re-rupture shape rehabilitation after non-surgical Achilles tendon rupture.

  • A reflexive thematic analysis of 15 semi-structured interviews (mean age 54.5 years; mean 8.9 months since rupture; interviews Aug–Nov 2023) identified three core themes: injury presentation and system entry; non-surgical immobilisation (boot vs cast) and self-management burden; rehabilitation dominated by fear of re-rupture and uncertainty about returning to sport.
  • Variability in early messaging and boot self-management was highlighted as a likely driver of protocol deviations and long-term functional deficit.
  • AI-enabled thematic frequency, timeline, and cross-segment analyses can rapidly expose actionable differences for patient education, protocol design, and service improvements.

What happened (methods & themes)

The study used purposive sampling at a UK NHS specialist clinic and reflexive thematic analysis to identify three themes from semi-structured interviews.

The authors conducted one-to-one semi-structured interviews with a mean duration of 30 minutes, transcribed the interviews verbatim, and applied Braun & Clarke reflexive thematic analysis using NVivo.

  • Key methodological note: data saturation was assessed after 10 interviews, and recruitment continued to 15.
  • Three themes emerged that blend physical, behavioural, and system-level factors, making the data suitable for thematic frequency, timeline, and co-occurrence analyses.

Implications for qualitative analysis of Achilles tendon rupture

For researchers & trialists

Researchers should prioritise capture of early messaging and boot-adjustment instructions in transcripts, because these short interaction fragments predict protocol adherence.

Researchers should triangulate thematic findings with objective measures such as heel-rise and imaging when possible, the study notes participants sought imaging reassurance after non-surgical care.

For physiotherapy services and clinicians

Physiotherapy services should standardise boot-adjustment education with written and video materials, because qualitative patterns show self-adjustment errors and feelings of abandonment when contact is limited.

Clinicians should address psychological barriers explicitly, because fear of re-rupture is a persistent theme that affects return-to-sport decisions.

For UX / service designers

UX and service designers should use cross-segment analysis to compare messages from emergency departments, primary care, and specialist clinics, because small message differences propagate into behaviour changes such as protocol deviations and early weightbearing.

Designers should map co-occurrence of 'boot discomfort', 'night removal', and 'contact unavailable' to identify priority UX fixes such as in-app reminders and on-demand clinician chat.

Problem: scattered transcripts & inconsistent coding

Evidano imports interview audio or transcripts, applies an imported topic guide as a custom codebook, and runs AI-assisted coding to produce consistent themes and subcodes in minutes.

Import interview audio or transcripts into Evidano, import the study’s topic guide as a custom codebook, and run AI-assisted coding to produce consistent themes and subcodes in minutes.

Problem: multilingual or noisy audio & clinician jargon

Evidano transcription supports custom dictionaries and PII redaction to ensure accurate transcripts and GDPR- and HIPAA-aware handling for clinical data.

Use Evidano transcription with a custom dictionary to capture medical terms such as 'Vacoped' and 'LAMP' and redact personal identifiers automatically.

Problem: linking themes to participant attributes

Evidano cross-segment analyses compare sporting versus non-sporting injuries, gender, or time-since-injury and export frequency tables for reporting or R analyses.

Use Evidano cross-segment analyses to compare sporting vs non-sporting injuries, male vs female participants, or different time-since-injury groups and export results for further analysis.

Problem: conveying fear & co-occurrence patterns

Evidano generates co-occurrence networks and hierarchical theme→subtheme visualisations to show how 'fear of re-rupture' ties to 'boot adjustments', 'healthcare contact', and 'return-to-sport' outcomes.

Generate co-occurrence networks and hierarchical visualisations to communicate the links between psychological themes and practical self-management issues.

Security & reproducibility

Evidano uses encrypted storage and proprietary LLMs tuned for qualitative research, it does not use customer data to train third-party models, supporting sensitive clinical projects.

Rely on Evidano’s encryption and model policies to meet reproducibility and data-protection needs for clinical qualitative research.

Checklist, reproduce this study in Evidano (7 steps)

Follow these seven steps to reproduce the study in Evidano.

1) Gather audio/transcripts and the interview topic guide; de-identify PII, or let Evidano redact automatically.

2) Upload files to Evidano and run transcription with a custom dictionary (medical terms: 'Vacoped', 'LAMP').

3) Import or create the codebook (three high-level themes) and run AI-assisted coding; review and lock codes.

4) Run thematic frequency and cross-segment analyses (sporting vs non-sporting; male vs female; time-since-injury).

5) Generate co-occurrence networks to surface relationships (fear ↔ boot adjustments ↔ service contact).

6) Extract exemplar quotes, create stakeholder-ready visual reports and share via secure export.

7) Iterate: re-run with new interviews to detect saturation (Evidano flags diminishing new themes).

Ethics note: non-diagnostic, research-focused analysis only, follow consent and local governance for clinical interview data.

FAQ: Achilles tendon rupture qualitative analysis

What did the PLoS One study of non-surgical Achilles tendon rupture find?

The PLoS One study found three core qualitative themes: injury presentation and system entry; non-surgical immobilisation and self-management burden; and rehabilitation dominated by fear of re-rupture and uncertainty about returning to sport.

The study used 15 semi-structured interviews (mean age 54.5; mean 8.9 months since rupture; interviews Aug–Nov 2023) and reported data saturation at around 10 interviews.

How were interviews analysed in the study?

The interviews were transcribed verbatim and analysed using Braun & Clarke reflexive thematic analysis in NVivo with independent coding by two researchers and team review following COREQ guidance.

The authors assessed saturation after 10 interviews and continued recruitment to 15 participants.

Which practical problems from the study can qualitative analysis address?

Qualitative analysis can surface variability in early messaging, boot self-management errors, and psychological barriers such as fear of re-rupture that affect rehabilitation behaviour.

Analysts can use thematic frequency, co-occurrence, and cross-segment comparisons to inform patient education, protocol design, and service fixes.

How can teams reproduce the study’s workflow using Evidano?

Teams can reproduce the study by uploading transcripts, using a three-theme codebook, running AI-assisted coding, and producing frequency and co-occurrence visualisations as described in the seven-step checklist.

The checklist includes automatic PII redaction, custom dictionaries for medical terms, and secure export of reports.

Wrapping up & next step

Briggs-Price et al. (PLoS One, June 29, 2026) provide a concise qualitative picture of non-surgical ATR recovery, emphasising early messaging, boot self-management, and fear-driven rehab decisions.

These patterns are amenable to AI-enabled thematic, frequency, and cross-segment analysis to inform patient education, protocol design, and service fixes.
