An interventional study of Augmented Feedback and Control Group in Low Back Pain, sponsored by Zurich University of Applied Sciences. Completed at 1 site in Switzerland. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2019-02-15.
Sponsored by Zurich University of Applied Sciences · Not applicable, Interventional, and Treatment
Exercise therapy is effective in improving pain experience and disability in patients with non-specific low back pain (NSLBP) and movement/postural control impairments. However, patients often find traditional exercises monotonous and discontinue their execution. Augmented feedback tools (AF) might improve patient adherence and therapy outcomes, but evidence is currently lacking on their effects on movement/postural control. In a pilot randomised controlled trial (RCT) on a population of patients with NSLBP and movement control impairment, treatment with physiotherapy and home exercise supported by AF is compared to traditional physiotherapy and home exercise treatment without AF (control group). The primary outcomes are defined as lumbar movement control and postural control, measured using an inertial measurement system.

Exclusion Criteria:
The exercises were conducted with the aim of improving postural- and movement control and awareness of the lumbar spine in both treatment groups. Both groups received nine 30-minute therapy sessions, during which they performed a series of exercises from an exercise catalogue. The exercises were selected based on their compatibility with the AF-system. Each patient performed impairment-specific exercises. The AF group received additional AF feedback during both the therapy sessions and the home exercise program, by combining the exercises with games designed to target movement control, body awareness, and stabilisation exercises.
Device: Augmented Feedback
The control group performed the impairment-specific exercises without AF. The control group was able to receive conventional visual feedback, such as use of mirrors, as deemed appropriate by the therapists but no AF.
Other: Control Group
An inertial measurement unit (IMU) system is the basis of the augmented feedback (AF) system, where the IMU-system communicates with a laptop using a bluetooth dongle. The corresponding software includes therapeutic games. Movements of the lower back and pelvis by the patient are used to control an avatars movement or the graphical interface in computer exercises. The AF-system provides real-time feedback regarding the patient's performance and helps to rectify incorrect execution of the exercises. The intervention took place at a physiotherapy clinic and in an home environment. In the physiotherapy clinic the patients exercised under the supervision of the physiotherapists. They continued the exercises at home as home exercises.

Change from Baseline ratio of the range of motion (ROM) of the stabilized lumbar spine (ROMLS) over the moving body segment, the hip (ROMHip)
Movement control was quantified using the ratio of the range of motion (ROM) of the stabilized lumbar spine (ROMLS) over the moving body segment, the hip (ROMHip) during the movement control test (lumbar spine (LS) over the hip)
Time frame: From Baseline to the completion of nine physiotherapy sessions, which are completed after a maximum of five weeks (Swiss standard prescription)
Changes from Baseline of the mean absolute deviation of lumbar agular displacement
Postural control was quantified using the mean absolute deviation of lumbar angular displacement (MAD)
Time frame: From Baseline to the completion of nine physiotherapy sessions, which are completed after a maximum of five weeks (Swiss standard prescription)
