This post explains how qualitative evidence can shape tailored preoperative physical activity programs for spine surgery candidates, focusing on patients with lumbar stenosis or disc herniation. The primary keyword is preoperative physical activity and this article is written for clinical researchers, physiotherapists, and UX teams designing behaviour-change interventions; it shows how thematic, theory-driven findings from a PLOS One qualitative study can be operationalised and scaled with AI-enabled synthesis.
Key Takeaways
Preoperative physical activity for patients awaiting spine surgery is constrained by pain, fear of harm, and access barriers, yet can be shifted by tailored, theory-driven support that addresses skills, beliefs, environment, and emotion, according to the PLOS One study (published August 4, 2026) PLOS One.
- The PLOS One study (published August 4, 2026) interviewed 18 patients between 21 August 2024 and 12 February 2025, with 11 patients having lumbar stenosis and 7 having lumbar disc herniation.
- The PLOS One study (published August 4, 2026) reported a mean participant age of 54.7 years (SD 17.3) and mean interview length of 35.5 minutes (SD 8.2).
- The PLOS One study (published August 4, 2026) identified five key Theoretical Domains Framework domains to target in interventions: skills, beliefs about capabilities, beliefs about consequences, environmental context and resources, and emotion.
- The PLOS One study (published August 4, 2026) noted that only about 17% of patients met WHO-recommended activity levels while waiting for lumbar spine surgery, highlighting the scope for preoperative programmes.
- Design implication from the PLOS One study (published August 4, 2026): combine symptom‑sensitive action plans, professional guidance, and habit scaffolds rather than issuing generic activity advice.
What Happened: study methods and core findings
The PLOS One study (published August 4, 2026) used data‑prompted semi-structured interviews with 18 surgical candidates to explore barriers and facilitators to preoperative physical activity.
According to the PLOS One study (published August 4, 2026), researchers coded interviews to the Theoretical Domains Framework and identified five key domains that most strongly influenced preoperative physical activity: skills, beliefs about capabilities, beliefs about consequences, environmental context and resources, and emotion.
According to the PLOS One study (published August 4, 2026), pain and functional limitation were transversal themes that reduced capability and increased avoidance across domains.
Participant voices in the PLOS One study (published August 4, 2026) illustrate the mechanisms: “I can’t trust my legs and hips to do anything that is [a] big exertion” (Patient 4, 70–79 years, lumbar stenosis) and “I know if I do something […], I’ll pay for it [in] the morning. Well, tonight I’ll feel it.” (Patient 15, 50–59 years, lumbar disc herniation).
According to the PLOS One study (published August 4, 2026), professional guidance and safe environments functioned as concrete facilitators: “It was good to have guidance to make sure I was doing it right, they [the physiotherapists] were getting the most benefit whatever I was doing.” (Patient 14, 70–79 years, lumbar stenosis).
Findings Snapshot
| Date | Metric | Value | Implication |
|---|---|---|---|
| Aug 4, 2026 | Sample size | 18 patients | Small qualitative sample supports in-depth mapping of barriers and facilitators to inform targeted interventions |
| Aug 4, 2026 | Diagnoses | 11 lumbar stenosis, 7 disc herniation | Findings likely generalise across common degenerative lumbar conditions in pre-op populations |
| Aug 4, 2026 | Mean age | 54.7 years (SD 17.3) | Population spans working-age to older adults; interventions must accommodate comorbidities |
| Aug 4, 2026 | Interview duration | Mean 35.5 minutes (SD 8.2) | Interviews were sufficiently deep to reach saturation for this study's objectives |
| Aug 4, 2026 | Activity prevalence | ~17% met WHO-recommended levels | Most patients waiting for surgery are inactive, creating an opportunity for prehab programmes |
Implications for clinical researchers and rehabilitation teams
Clinical researchers should treat preoperative physical activity as a multi-domain problem, not a single education need, according to the PLOS One study (published August 4, 2026).
- According to the PLOS One study (published August 4, 2026), target skills deficits by offering supervised, graded practice and explicit instructions to rebuild confidence.
- According to the PLOS One study (published August 4, 2026), address beliefs about consequences with motivational interviewing and experience‑based exposure to safe activity.
- According to the PLOS One study (published August 4, 2026), reduce environmental barriers by recommending home-based or hybrid delivery and low‑cost resources where financial or access constraints exist.
- According to the PLOS One study (published August 4, 2026), incorporate emotional supports and habit scaffolds because emotion and routine were strong determinants of whether patients acted on motivation.
Health services designers should prioritise brief, symptom‑sensitive action plans and consistent guidance across providers, because the PLOS One study (published August 4, 2026) reported that inconsistent advice and lack of guidance undermined patient confidence.
How Evidano helps translate these qualitative findings into programs
Evidano definition
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
According to the Evidano platform approach, researchers can ingest transcripts and prompts, then produce thematic maps aligned to frameworks like the Theoretical Domains Framework to prioritise intervention targets.
Problem: small qualitative datasets, slow synthesis → Solution: rapid thematic mapping
Problem statement: The PLOS One study (published August 4, 2026) used manual, line-by-line coding that is rigorous but time consuming for design teams.
Evidano solution: Evidano automates initial deductive mapping to frameworks such as the TDF and surfaces high-frequency beliefs and illustrative quotes, accelerating synthesis while preserving auditability. See Evidano features for thematic and code-hierarchy tools.
Problem: personalised intervention content is needed → Solution: cross-segment analysis
Problem statement: The PLOS One study (published August 4, 2026) suggests distinct patient profiles (low fitness/high barriers, higher fitness/strong facilitators, and low fitness/open to change) that require tailored messaging.
Evidano solution: Evidano supports cross-segment analyses to compare codes and quote distributions by subgroup, enabling teams to design profile-specific action plans and prototype messaging quickly.
Problem: interviews and multimodal data need consistent capture → Solution: integrated transcription and prompts
Problem statement: The PLOS One study (published August 4, 2026) relied on recorded interviews and field notes, which are easy to fragment without a consistent pipeline.
Evidano solution: Evidano provides secure transcription with custom dictionaries and redaction plus structured prompts so research teams can standardise transcripts and ensure quotes map back to participant metadata for triangulation. For more on transcription see Evidano speech-to-text.
FAQ: preoperative physical activity
What are the main barriers to preoperative physical activity for spine surgery patients?
+
Direct answer: The main barriers are pain and functional limitation, fear of harm or symptom exacerbation, unsuitable environments, limited professional guidance, and negative emotions, according to the PLOS One study (published August 4, 2026).
Supporting detail: The PLOS One study (published August 4, 2026) identified those themes across five key TDF domains; participants described unpredictable pain, balance problems, and learned avoidance that limited daily activity.
Which facilitators should interventions prioritise?
+
Direct answer: Interventions should prioritise professional guidance, social support, symptom‑sensitive action plans, and habit formation, according to the PLOS One study (published August 4, 2026).
Supporting detail: The PLOS One study (published August 4, 2026) reported that physiotherapy guidance and accessible environments enabled patients to adapt safely and feel confident about activity.
Can qualitative findings be scaled into program design?
+
Direct answer: Yes, qualitative findings can be scaled into program features and messaging when thematic maps are combined with cross-segment frequency analysis and exemplar quotes, as recommended by the PLOS One study (published August 4, 2026).
Supporting detail: The PLOS One study (published August 4, 2026) recommends mapping behaviour change techniques to identified TDF domains; AI tools can speed the mapping and maintain traceability to source quotes.
How should researchers measure change in preoperative activity?
+
Direct answer: Researchers should pair qualitative process data with objective activity measures such as accelerometers and with pre/post measures of beliefs and function, as suggested in the PLOS One study (published August 4, 2026).
Supporting detail: The PLOS One study (published August 4, 2026) noted the absence of objective activity metrics in that study and recommended accelerometry for future feasibility and outcome trials.
Conclusion & Next Steps
The PLOS One study (published August 4, 2026) shows that preoperative physical activity behaviours are shaped by an interplay of physical, emotional, and contextual factors that must be assessed and targeted individually.
The PLOS One study (published August 4, 2026) implies that brief, safe, and guided prehabilitation that builds skills, reframes consequence beliefs, and scaffolds routines is more promising than generic advice.
If you design preoperative programs or conduct qualitative research, Evidano can accelerate synthesis from interviews, map findings to the TDF, and help you operationalise profiles into tailored interventions; see Evidano features to learn more.
Next step: translate the PLOS One findings into a pilot prehab protocol that pairs symptom‑sensitive action plans with supervised guidance and objective monitoring.
