Brief 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.

Outcome Measures

Primary Outcomes (1)

• Lumbar Stiffness Disability Index

  'Lumbar Stiffness Disability Index,' was developed by Hart et al. in 2013. It comprises 10 items and aims to assess the degree of impairment in the performance of daily activities due to the lack of mobility in individuals with compromised or lost lumbar spine flexibility. It queries the degree of execution of 10 movements related to the lumbar region in daily life, scored between 0 and 40, where a higher score indicates a higher level of disability (loss of ability). It can also be converted into a 100-point version. Developed as a 5-point Likert scale, it ranges from 0, indicating no impact and the activity being entirely achievable, to 4, meaning the activity is almost impossible to perform. Participants are asked to mark the value that is suitable for them in each activity.

Interventions

Lumbar Stiffness Disability Index OTHER

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.

Also known as: Oswestry Disability Index, Functional Reach Test, Goniometric Measurements of Lumbar Region, Trunk Flexion and Hamstring Length Flexibility Test, Trunk Lateral Flexion Flexibility Test
