Wearable Spine Assessment in Adults With and Without Low Back or Neck Pain (AxiSens-01)

16. juni 2026 oppdatert av: Ashkan Vaziri

Wearable Spine Assessment in Adults With and Without Low Back or Neck Pain: A Single-Site Observational Feasibility and Validity Study

This is a single-site, prospective, observational, single-visit feasibility and validity study. Adult participants with and without low back or neck pain will be screened, consented, and enrolled to undergo a structured wearable-sensor-based spine assessment in a single on-site visit.

Approximately 20 participants will be enrolled at a single site:

  • Approximately 10 adults with self-reported chronic or subacute low back or neck pain (LBP/Neck Pain group)
  • Approximately 10 adults without current back or neck pain (Control group)

The AxiSens battery includes the Fingertip-to-Floor (FTF) test for lumbar flexion, the Chin-to-Chest (CTC) test for cervical flexion, a seated Trunk Stability Test on an unstable surface, the Cervical Flexor Endurance Test, the five-times sit-to-stand F5xSTS) test, and a brief functional task module covering overhead and forward reach.

To support intra-rater repeatability characterization, the AxiSens wearable assessment is performed twice within the same visit by a single trained operator, with sensor doffing and re-donning between the two assessments. A short rest interval is provided between the two assessments.

Following the on-site assessment, participants complete a brief end-of-session usability and tolerability questionnaire and the Technology Acceptance Model (TAM) questionnaire.

Detaljert beskrivelse

Low back and neck pain are among the most common, costly, and disabling musculoskeletal conditions in the United States and worldwide. Low back pain is the leading cause of years lived with disability globally, and neck pain is consistently within the top ten. Both are leading drivers of healthcare expenditure, exceeding spending on diabetes, heart disease, and cancer in some recent analyses. Despite this magnitude, the clinical assessment of spine function remains heavily reliant on subjective self-report and clinician examination, with limited use of objective, quantitative, point-of-care measurement tools.

Wearable sensors, particularly inertial measurement units (IMUs), have matured into a credible technology base for objective musculoskeletal assessment. Multiple research groups have published validation studies establishing the accuracy of IMU-based segmental kinematics against optical motion capture, and feasibility studies demonstrating the utility of wearable kinematics in occupational and clinical settings. Most published wearable-spine assessment work to date has focused on lumbar kinematics in isolation, with cervical kinematic assessment less well-developed and integrated full-spine kinematic assessment relatively rare.

Recent peer-reviewed work demonstrated the feasibility of using wearable IMU technology to objectively assess cervical and upper-back posture in high-risk professional populations during prolonged work tasks. This work established that IMU-based monitoring of upper-body kinematics is feasible in real-world settings and that the methodology generates objective, reproducible data suitable for biofeedback and longitudinal monitoring. The current study extends this established methodology to a broader spine assessment configuration covering cervical, thoracic, lumbar, and pelvic segments, and integrated with validated patient-reported outcome instruments to enable a holistic biopsychosocial assessment of spine function.

The objective of this study is to evaluate the ability of a wearable, multi-modal spine assessment system - AxiSens - to discriminate between adults with low back or neck pain and healthy controls, and to characterize its intra-rater repeatability and workflow feasibility. There is no investigational therapeutic intervention. All participants undergo the same wearable-sensor-based spine assessment procedures in a single on-site visit. Approximately 20 participants will be enrolled, comprising approximately 10 participants in the LBP/Neck Pain group and approximately 10 participants in the Control group.

To support intra-rater repeatability characterization within this single-visit design, the AxiSens wearable assessment is performed twice within the visit by a single trained operator, with sensor doffing and re-donning between the two assessments and a short rest interval. The two within-visit assessments support estimation of the intra-rater repeatability of AxiSens-derived kinematic and composite outcomes.

Tiltaksbeskrivelse
Tidsramme
Numeric Pain Rating Scale
Tidsramme: Baseline Visit
The Numeric Pain Rating Scale (NPRS) is an 11-point, self-reported assessment tool where 0 means "no pain" and 10 represents the "worst pain imaginable." It is scored simply by recording the whole number indicated by the patient, usually evaluated for current, average, or worst pain levels.
Baseline Visit
Neck Disability Index
Tidsramme: Baseline Visit
The Neck Disability Index (NDI) is a 10-question survey that measures how neck pain affects activities of daily life. Each section is scored from 0 to 5, where 5 is a worst outcome. The total is calculated as a percentage to determine the level of functional disability.
Baseline Visit
Oswestry Disability Index
Tidsramme: Baseline Visit

The Oswestry Disability Index (ODI) is the gold standard patient-reported questionnaire used to quantify functional disability in individuals with low back pain. It evaluates 10 everyday activities, such as personal care, lifting, walking, and sleeping.

Each of the 10 sections is rated on a 6-point scale from 0 to 5, where 0 indicates no disability and 5 represents the most severe disability.

Baseline Visit
Pain, Enjoyment, General Activity (PEG-3)
Tidsramme: Baseline Visit
The PEG-3 is used to assess chronic pain. Patients rate their pain, enjoyment of life, and general activity on a scale of 0 to 10 based on the past week. A higher score indicates a worst outcome.
