The aim of this feasibility study is to evaluate the practicality of conducting a future randomized controlled trial comparing two rehabilitation approaches for older adults with degenerative chronic low back pain: impairment-based treatment (IBT) and a modified short Functional Restoration Program (FRP).
Impairment-based treatment is an individualized approach in which interventions are tailored to the patient's specific physical deficits, such as limitations in mobility, strength, and motor control. In contrast, the Functional Restoration Program is a structured, standardized approach focusing on improving overall functional capacity through progressive exercise, movement retraining, and activity-based rehabilitation.
Participants will be randomly allocated to one of the two groups. Both interventions will be delivered by trained physiotherapists following standardized protocols over a 6-week period, with supervised sessions conducted according to a predefined rehabilitation schedule.

| Pain intensity | -Numerical pain rating scale (NPRS) from 1 to 10 , minimum 1 and maximum 10 . The bigger the numbers means the worse . | Baseline (week =zero) Intervention Mid Intervention (week 2) Post intervention (week 6) Follow up (1 month post intervention) |
| Function | Modified Oswestry disability Index the MOLBPDQ consists of 10 patient-completed questions in which the response options are presented as 6-point Likert scales. Scores range from 0% (no disability) to 100% (most severe disability). | Baseline (week =zero) Intervention Mid Intervention (week 2) Post intervention (weak 6) Follow up (1 month post intervention) |
| Strength | Hand held dynamometer (activ force 2) | Baseline (week =zero) Intervention Mid Intervention (week 2) Post intervention (week 6) Follow up (1 month post intervention) |
| Eligibility rate | Eligibility rate will be calculated as the proportion of screened participants who meet the study eligibility criteria. All individuals assessed for participation will be recorded, including those who are eligible and those who are excluded with reasons for exclusion. Eligibility Rate (%) = Number of Eligible Participants ÷ Number of Screened Participants × 100 | Post intervention (week 6) |
| Retention | Participant Retention Rate Description: Percentage of enrolled participants who complete the study through the final follow-up assessment, as determined from study participation and completion records. Unit of Measure: Percentage (%) Measurement Tool: Study participation and completion records | Post intervention (week 6) Follow up (1 month post intervention) |
| Measure | Description | Time Frame |
|---|---|---|
| Adherence | Participant adherence will be assessed throughout the intervention period using session attendance records, completion of the prescribed exercise program, and therapist documentation. Attendance adherence will be calculated as the percentage of attended treatment sessions out of the total scheduled sessions. Home exercise adherence will be monitored using a patient exercise diary or checklist, where participants record the frequency of performed exercises. Overall adherence will be considered acceptable when the participant completes at least 80% of the scheduled sessions and prescribed home exercises. Adherence rate will be calculated using the following formula: Adherence Rate (%) = Number of Completed Sessions or Exercises ÷ Total Prescribed Sessions or Exercises × 100 |

| Modified Functional restoration program | Other | The modified short Functional Restoration Program (FRP) is a structured, time-efficient rehabilitation approach designed to improve functional capacity in patients with chronic low back pain. It is based on a biopsychosocial model and combines progressive physical reconditioning with functional task training and patient education. The program includes aerobic conditioning, strengthening exercises, movement retraining, and graded activity exposure, with emphasis on restoring tolerance to daily activities rather than focusing solely on pain reduction. In this modified short version, the program is adapted for older adults and delivered over a limited timeframe, with standardized session content and progression criteria to ensure consistency, safety, and feasibility within a clinical outpatient setting. |

| Intervention fidelity |
Percentage of predefined treatment components delivered according to the study protocol, as assessed using a standardized intervention fidelity checklist completed by an independent assessor during treatment sessions. Fidelity scores will be calculated as the proportion of protocol-required components successfully delivered.

Adverse events may include increased pain, excessive fatigue, symptom aggravation, dizziness, discomfort during or after treatment, or any other unexpected clinical complaint reported by the participant or observed by the therapist. | every session |
