About this study
this study aims to evaluate balance using the biodex balance system among patients with spondylosis, spondylolisthesis, and lumber disc prolapse.
Read the detailed description
Low back pain is one of the most common causes of disability globally . While postural balance impairments have been widely documented in individuals with low back pain, there is limited understanding of how these impairments vary across specific subcategories of specific low back pain. Low back pain is generally categorized into non specific and specific types.
Non-specific LBP approximately accounts for 85-90% of all low back pain cases (Hartvigsen et al., 2018). In contrast, specific low back pain arises from a recognizable pathology such as structural abnormalities. The most common causes of specific low back pain are lumbar spondylosis, spondylolisthesis, and lumbar disc prolapse. Lumbar spondylosis has a prevalence of 74% in individuals over 60 years confirmed with radiographic findings. Spondylolisthesis affects approximately 6-11.5% of adults , lumbar disc prolapse accounts for 2-5% of all low back pain cases.
Balance deficiency among patients with spondylosis, spondylolisthesis and lumber disc prolapse was reported in literature by different objective assessment tools. Individuals with low back pain exhibit measurable deficits in balance and postural stability compared to healthy controls . Also, the chronicity of low back pain affects both static and dynamic balance.
Assessment and detection of balance deficiency among patients with spondylosis, spondylolisthesis and lumber disc prolapse will allow physical therapists to design individualized rehabilitation programs. Improve understanding of interventions focusing on core stabilization, proprioceptive retraining and dynamic balance. This may improve postural control, enhance gait performance, reduce fall risk and support better functional outcomes in daily activities.
Thus, there was a need to study the difference in balance using the biodex balance system among patients with spondylosis, spondylolisthesis and lumber disc prolapse. The current study may provide a more conclusive insight in evaluation and treatment of patients with low back pain.

Low back pain (LBP) is a leading cause of disability worldwide and is often associated with postural and balance impairments. However, limited evidence exists on how these deficits differ among specific types of LBP such as lumbar spondylosis, spondylolisthesis, and disc prolapse. Understanding these variations is crucial for accurate assessment and targeted rehabilitation. Evaluating balance using the Biodex Balance System can help identify the extent of impairment and guide physiotherapists in developing individualized rehabilitation programs that enhance postural control, stability, and functional performance, ultimately improving quality of life and reducing fall risk among LBP patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Postural stability ( Overall Stability Index)
Postural stability will be assessed using the Biodex Balance System through the Overall Stability Index (OSI).The OSI reflects the degree of platform sway, with lower values indicating better balance control. Measurements will be taken under six standardized conditions to evaluate both static and dynamic balance performance. These conditions include:
Double-Leg, Eyes Open (DLEO)
Double-Leg, Eyes Closed (DLEC)
Single-Leg, Eyes Open (SLEO) - Dominant Leg
Single-Leg, Eyes Closed (SLEC) - Dominant Leg
Single-Leg, Eyes Open (SLEO) - Non-Dominant Leg
Single-Leg, Eyes Closed (SLEC) - Non-Dominant Leg
Measured: All postural assessments will be performed for 20 seconds
Postural Stability: Medial-Lateral Stability Index (MLSI)
The Medial-Lateral Stability Index (MLSI) will be obtained from the Biodex Balance System to assess side-to-side postural control. Higher MLSI values indicate greater medial-lateral sway, while lower values reflect better stability in the frontal plane. the measurement will be in six conditions:
Double leg eyes open (DLEO), Double leg eyes closed (DLEC), Single leg eye open (SLEO) Dominant leg, Single leg eye closed (SLEC) Dominant leg, Single leg eye open (SLEO) Non-Dominant leg and Single leg eye closed (SLEC) Non-Dominant leg
Measured: All postural assessments will be performed for 20 seconds
postural stability: Anterior-Posterior Stability Index (APSI)
The Anterior-Posterior Stability Index (APSI) will be measured using the Biodex Balance System to evaluate forward-backward postural control. Lower APSI values indicate improved stability in the sagittal plane, whereas higher values reflect increased anterior-posterior sway.
the measurement will be in six conditions: Double leg eyes open (DLEO), Double leg eyes closed (DLEC), Single leg eye open (SLEO) Dominant leg, Single leg eye closed (SLEC) Dominant leg, Single leg eye open (SLEO) Non-Dominant leg and Single leg eye closed (SLEC) Non-Dominant leg
Measured: All postural assessments will be performed for 20 seconds
Limits of Stability
Limits of Stability will be assessed using the Biodex Balance System to evaluate the participant's ability to intentionally shift their center of gravity toward predefined targets without losing balance. The test measures directional control, reaction time, movement speed, and endpoint accuracy, with higher scores reflecting better dynamic balance and voluntary postural control. the measurement condition will be in Double leg eyes open (DLEO)
Measured: All postural assessments will be performed for 20 seconds
Secondary outcomes (2)
Arabic version of Numerical pain rating scale (Ar-NPRS)
The Numerical Rating Scale is used to quantify the intensity of a subjective symptom-most commonly pain-on a 0 to 10 scale. A score of 0 represents no pain or no symptom, while a score of 10 indicates the worst imaginable pain or maximum symptom severity. Higher scores reflect a worse outcome, indicating greater intensity.
Measured: Periprocedural
Arabic version of Oswestry disability index (Ar-ODI)
The arabic Oswestry Disability Index is a questionnaire used to assess disability related to low back pain. Scores range from 0 to 100, where 0 indicates no disability and 100 indicates maximum disability. Higher scores represent a worse outcome, reflecting greater functional limitation.
Measured: Periprocedural

Questions about this trial
What is this clinical trial studying?
A study testing Assessment of balance will be measured by The Biodex Balance System (BBS) which computes Postural Stability key indices: the medial-lateral stability index (MLSI), anterior-posterior stability index in people with Low Back Pain and Spondylolisthesis, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postural stability ( Overall Stability Index) (time frame: All postural assessments will be performed for 20 seconds). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
