Associations between postural kyphosis and tactile sensation, proprioception, and body image in young individuals: an analytical cross-sectional study.
Observational study in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06420869 (Investigation of the Effect of Thoracic Kyphosis on Posture, Proprioception and Perception of Postural Appearance in Young Individuals), which is not on this map.

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.

Abstract
backgroundPostural kyphosis is considered a common spinal alignment disorder characterized by an increased thoracic curvature without structural vertebral abnormalities. Changes in sagittal alignment may affect load distribution throughout the body and alter sensorimotor integration, thereby influencing somatosensory inputs and body perception. However, to our knowledge, no previous study has simultaneously evaluated trunk and plantar tactile sensitivity, proprioception, and body image perception in young adults with postural kyphosis. Understanding these multidimensional alterations is clinically important, as they may contribute to impaired postural control and inform rehabilitation strategies. Therefore, this study aims to compare trunk and plantar tactile sensitivity, trunk and ankle joint position sense, and body image perception between young adults with postural kyphosis and healthy individuals of similar age.
methodsThis analytical cross-sectional study included 62 individuals aged 18-25 years, comprising 31 individuals with postural kyphosis and 31 healthy controls. Thoracic kyphosis angle was measured using the flexicurve method. Tactile sensation in the trunk and foot regions was assessed using the Semmes-Weinstein monofilament test, while proprioception was evaluated using a digital goniometer to assess joint position sense. Body image sensation was assessed using the Kyphosis-Specific Spine Appearance Questionnaire (KSAQ).
resultsIndividuals with postural kyphosis demonstrated significantly reduced tactile sensation at the T4, T5, and T6 vertebral levels (p < 0.001) and at the first metatarsal region of both feet (p < 0.05) compared with healthy controls. Proprioceptive sensitivity was significantly lower in the postural kyphosis group during trunk flexion, extension, and right and left lateral flexion, as well as during ankle dorsiflexion and plantar flexion (all p < 0.001). In addition, KSAQ scores were significantly higher in individuals with postural kyphosis than in healthy controls (p < 0.001).
conclusionThe findings of this study suggest that postural kyphosis is associated not only with altered spinal alignment but also with changes in tactile sensation, proprioception, and body image in young individuals. These results highlight the importance of considering sensory-motor integration and psychosocial aspects when planning rehabilitation strategies for individuals with postural kyphosis.
