Walking Training After Lumbar Decompression Surgery

2026. november 9. frissítette: salih tan, Istanbul Medipol University Hospital

Effectiveness of Task-Specific Gait Training After Lumbar Decompression: An Assessor-Blinded Randomized Controlled Trial

This study will test whether adding walking practice to standard rehabilitation improves balance while walking after lower back surgery. The study will include 60 adults aged 30 to 65 who still have difficulty walking or keeping their balance after surgery to relieve pressure on the nerves in the lower back caused by a narrowing of the spinal canal.

Participants will be assigned by chance to one of two groups. One group will receive standard rehabilitation. The other group will receive the same rehabilitation plus extra practice with everyday walking tasks, such as changing speed, turning, and stepping over obstacles. Both groups will attend three supervised sessions per week for eight weeks.

Participants will be assessed before starting the program and again at weeks 4 and 8. The person who performs the assessments will be unaware of each participant's group assignment. The main outcome is balance during walking tasks at week 8. The study will also assess walking speed and distance, the ability to get up from a chair and move around, back and leg pain, and how back problems affect daily activities.

Részletes leírás

This is an assessor-blinded, parallel-group randomized controlled trial in adults with persistent walking or balance difficulties after lumbar decompression without fusion for lumbar spinal stenosis. Baseline assessments will take place 6 to 12 weeks after surgery, before randomization. Participants will be assigned in a 1:1 ratio to standard rehabilitation or standard rehabilitation plus task-specific gait training.

The additional training will be progressed according to each participant's ability to complete the walking tasks safely and without a marked increase in symptoms. The comparison will estimate the effect of adding the training program to standard rehabilitation, including the additional exercise time and therapist contact.

The primary analysis will compare Functional Gait Assessment (FGA) total scores at week 8 between groups, adjusting for baseline FGA scores. Weeks 4 and 8 are measured from the start of the rehabilitation program. Week 4 assessments are exploratory. Adverse events will be monitored and documented throughout the intervention period.

Aktív összehasonlító: Standard Rehabilitation

Participants will receive approximately 40 minutes of supervised standard rehabilitation per session, three times per week for eight weeks. They will also receive the standard home exercise program.

The supervised program includes a warm-up, trunk control exercises, lower-limb strengthening, flexibility and mobility exercises, comfortable walking on a level and unobstructed surface, and a cool-down. Exercises are individualized according to postoperative restrictions, symptoms, and movement quality. Both groups receive the same home program, which takes approximately 15 to 20 minutes and is performed three days per week.

Kísérleti: Standard Rehabilitation Plus Task-Specific Gait Training

Participants will receive the same supervised standard rehabilitation and home exercise program as the active comparator group. Each supervised session will also include approximately 20 minutes of task-specific gait training, for a total of approximately 60 minutes per session, three times per week for eight weeks.

The supervised program includes a warm-up, trunk control exercises, lower-limb strengthening, flexibility and mobility exercises, comfortable walking on a level and unobstructed surface, and a cool-down. Exercises are individualized according to postoperative restrictions, symptoms, and movement quality. Both groups receive the same home program, which takes approximately 15 to 20 minutes and is performed three days per week.

The additional supervised training includes starting and stopping, changing walking speed and step length, turning, side-stepping, and stepping over obstacles. Tasks progress from individual skills to courses that combine multiple walking tasks. Difficulty is adjusted according to each participant's ability to complete the tasks safely and without a marked increase in symptoms.

Időkeret
Functional Gait Assessment (FGA) Total Score at Week 8
Időkeret: Week 8 after the start of the rehabilitation program

The Functional Gait Assessment evaluates balance during 10 walking tasks. Each item is scored from 0 to 3, yielding a total score from 0 to 30. Higher scores indicate better walking balance. The primary analysis will compare week 8 scores between groups, adjusting for baseline FGA scores.
