Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The association between pressure pain threshold and different aspects of low back pain has garnered attention over the years. However, since most of such studies in the past employed cross sectional designs, a longitudinal study design with follow-up measurements is required to further investigate this relationship. Studying this relationship will not only offer insights into the phenomenon of pain but may also bring us one step closer to achieving the seemingly insurmountable goal of objectively measuring back pain and its different dimensions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is aimed to examine and evaluate the true extent of the relationship between pressure pain threshold (PPT) and different aspects of somatic pain, by studying the interplay between PPT and different variables, and by further exploring the predictive capability of PPT values to estimate pain intensity, pain affect and disability associated with chronic low back pain (CLBP). In order to estimate these dimensions a calculator based on mathematical equations using different predictive models will be developed. This tool (calculator) will take into account PPT reading from the lower back region and some other variables having confounding effects on PPT and pain, and will be able to predict pain intensity, affect and associated disability with reasonable accuracy. Patients with chronic low back pain shall be the target population and shall be recruited through referrals from the medical Out-Patients Department of Institute of Physical Medicine \& Rehabilitation, Dow University of Health Sciences and Department of Rehabilitation Medicine PNS-Shifa Hospital, Karachi, Pakistan after initial screening in accordance with the inclusion and exclusion criteria. Screened patients shall then be briefed about the research project. After explaining the study objectives, procedures, potential benefits and discomforts, written informed consent shall be obtained from the patients. Only upon their agreement shall they become study participants and undergo assessments. The study participants shall receive handouts to document Depression and Anxiety, Pain Intensity, Pain Affect, and Disability. Pressure pain threshold (PPT) shall be measured using a manual Algometer. These measurements shall be followed by a session of physiotherapy treatment, after which Pain Intensity, Pain Affect, and Disability shall be recorded again.

SEGMENTAL STABILISATION TRAINING (SST)

Segmental Stabilisation Training is an established treatment technique for chronic low back pain

Group Type OTHER

segmental stability training

Intervention Type OTHER

SEGMENTAL STABILISATION TRAINING (SST): This part of the therapy shall involve Isometric co-contraction of Lumbar Transversus abdominis and Lumbar Multifidus. The patient shall perform 10 repetitions of abdominal drawing-in manoeuvre with 30-40% Maximal Voluntary Contraction (MVC) with a 10-second hold in specific prescribed positions.
