Summary

Despite advancements in assessment and treatment methods, diagnosing and treating lower back pain remains challenging for researchers and clinicians. The literature doesn't support a definitive cause for the onset of back pain, as risk factors are diverse, population-specific, and inadequate when solely associated with back pain. Evaluating spinal stiffness is crucial, as it can either cause or result from back pain. However, assessing spinal stiffness lacks standardized and reliable methods, and studies regarding its relation to pain and movement are insufficient. The measurement principles and optimization techniques for assessing spinal stiffness haven't been fully explained or practically recommended. Creating a practical diagnostic process involving examination procedures, a diagnostic checklist, and practical indices for evidence in clinical assessments is crucial. Early identification of individuals at risk of prolonged disability and illness is vital since specific interventions can be developed in the early stages. The Lumbar Stiffness Disability Index (LSDI) stands out among valid and reliable tools for assessing lumbar stiffness and disability. It is an index designed in English, translated into languages like Chinese and Japanese, proving to be a useful tool to describe a patient's condition based on pain, function, and disability, tracking changes throughout treatment.

Detailed description

Back pain is typically described as localized stiffness, often associated with muscle tension or in the lower border of the ribs and upper gluteal region, radiating or non-radiating to the leg. Back pain can be acute, subacute, or chronic, classified as such if it lasts less than six weeks, between six weeks and three months, or more than three months, respectively. Chronic back pain, especially, exhibits a high prevalence and continues to rise with industrialization, peaking in the 50-55 age group, with a notable increase in prevalence after the age of 80. It is more common in women. According to 2020 data from the World Health Organization, back pain has affected 619 million people globally, with an estimated increase to 843 million by 2050 due to population growth and aging. Back pain affects individuals of all age groups and is a leading cause of disability worldwide, imposing a significant financial burden on patients. Non-specific back pain accounts for approximately 90% of all cases. Non-specific back pain poses a significant public health issue, lacking a sufficiently reliable and valid classification system for diagnosis in the literature. Imaging methods have limited effectiveness in diagnosis, as individuals with chronic back pain often present non-specific findings in imaging studies. Even asymptomatic patients frequently exhibit abnormal findings. Despite advancements in assessment and treatment methods, diagnosing and treating back pain remains challenging for both researchers and clinicians. The literature does not support a specific cause for the onset of back pain, as risk factors are diverse, population-specific, and associating back pain alone is inadequate. Spinal segmental stiffness can either cause or result from back pain and is widely assessed in clinical and research settings. Despite frequent use of manual techniques in clinical assessments, the reliability of spinal stiffness assessment is weak, and studies on its relationship with pain and movement are insufficient. Existing reviews have not fully explained the principles of measurement methods for spinal stiffness or provided practical recommendations for optimizing measurements. To demonstrate evidence in clinical assessments, a practical diagnostic process involving examination procedures and a diagnostic checklist with a specific index is crucial. Early identification of individuals at risk of prolonged disability and illness is essential, as specific interventions can be developed in the early stages. Improvement becomes more challenging as symptoms persist and the condition becomes chronic. When examining the literature, the Lumbar Stiffness Disability Index (LSDI) stands out among valid and reliable assessment tools for evaluating lumbar stiffness. Developed in English, translated into languages such as Chinese and Japanese, the LSDI is becoming widely recognized as a useful index for assessing lumbar spine rigidity and flexibility. The creation of a Turkish version of this index is considered valuable for clinical use.

Type	Name	Description
OTHER	Lumbar Stiffness Disability Index	The development and evaluation of the Turkish version of the Lumbar Stiffness Disability Index (LSDI) are planned. After ensuring the eligibility of adult participants included in the study, language validity will be established for the Turkish version of LSDI, and internal consistency will be assessed using Cronbach's alpha coefficient. Additionally, the test-retest reliability of the index will be evaluated by reapplying it to participants with a one-week interval. For external structure validity, LSDI scores will be correlated with Oswestry Disability Index, Functional Reach Test, and goniometric measurements. The study will include demographic data and measurements to examine the eligibility of individuals with specific medical conditions for the intervention.
