Development and Content Validation of an Exercise-Based Framework for the Management of Lumbar Radiculopathy.
Review in Physiotherapy research international : the journal for researchers and clinicians in physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and purposeCurrent guidelines for the management of lumbar radiculopathy recommend patient education, staying active, manual therapy, and nonsteroidal anti-inflammatory drugs (NSAIDs) as first-line treatments. Physiotherapy-specific interventions for low back pain that radiates to the leg include specific trunk muscle activation, muscle strengthening and endurance, movement control, centralisation, directional preference exercises and nerve mobilisation. While exercise therapy is widely recognised as an effective non-invasive intervention, there is currently limited evidence for a standardised framework that integrates different evidence-based exercise approaches and clinical expertise into a structured, practically applicable protocol. The purpose of this study was to develop and content-validate a structured, evidence-based exercise framework for the physiotherapy management of lumbar radiculopathy.
methodsA comprehensive review of the literature supplemented by expert input with at least 10 years of experience was conducted to identify commonly prescribed exercise interventions for lumbar radiculopathy. Based on the identified impairments and functional deficits associated with the condition, an initial draft framework, which included trunk stabilization, mobility and flexibility training, was constructed. The draft framework was then subjected to expert validation using the content validity index (CVI) and modified kappa to confirm the relevance and perceived ease of performance of exercise by 10 physiotherapists.
resultsThe 4-stage exercise framework demonstrated excellent agreement with high CVI (100%-90%) and modified kappa (1-0.90). While some exercises of phase 2 and phase 3 were considered slightly difficult to perform, they were relevant for the condition. DISCUSSION: The developed exercise framework exhibited excellent content validity, supporting its relevance and perceived ease of performance in physiotherapy practice for managing patients with lumbar radiculopathy.
