Trial summary

Manual wheelchairs allow individuals with spinal cord injuries (SCI) to safely and effectively access their environment. However, continual exposure to whole body vibration (WBV) is one of many contributing factors to neck pain, back pain, and fatigue in wheelchair users with SCI. Read more about this study

About this study

Official title: Effects of In-wheel Suspension in Reducing Vibration, Neck, and Back Pain

Manual wheelchairs allow individuals with spinal cord injuries (SCI) to safely and effectively access their environment. However, continual exposure to whole body vibration (WBV) is one of many contributing factors to neck pain, back pain, and fatigue in wheelchair users with SCI.

Vibration-reducing in-wheel suspension has the potential to mitigate issues associated with long-term manual wheelchair propulsion. Evidence is lacking on how well these systems work for reducing harmful shock and vibration, pain and fatigue. The purpose of this study is to examine how these wheels change the vibration levels manual wheelchair users are exposed to and how they impact pain and fatigue.

Read the detailed description

Objective: The purpose of this project is to examine how Integral or in-wheel suspension impacts shock, vibration, pain and fatigue in manual wheelchair users with spinal cord injury who have chronic neck or back pain, defined as continuous or daily recurring pain that has been present for more than 3 months.

Experimental Design: This study consists of 2 phases. The first phase is a non-experimental post-test only design. The second phase is a non-experimental pretest-post-test design.

Methods: Thirty participants will be recruited to participate.

At Baseline (visit 1) participants will be asked to complete the study questionnaires and a standardized mobility course using a pair of standard wheelchair wheels (spoked rim), Spinergy lightweight carbon fiber wheels, and Loopwheels. Vibration exposure will be measured during the various propulsion tasks. The participant will be blinded to the type of wheel being used in the trial. Participants will be given a set of wheels (either Spinergy or Loopwheels) to use at home for the 12-week intervention.

Participants will use the in-wheel suspension wheels in their normal daily routine for 12-weeks. During this time, they will receive online surveys three times per week covering pain and fatigue experienced in various parts of the body.

At Closeout (Visit 2), participants will be asked to return to the lab to collect final outcomes, complete an exit survey and have their wheels swapped out for their original set.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Suspension WheelOther

    Also called Spinergy or Loopwheel

    Participants will be given a pair of Spinergy or Loopwheels to use during the 12-week intervention period. The Spinergy wheels consist of a lightweight carbon fiber material with natural shock absorbing properties. Loopwheels offer a rigid rim, a mid-wheel shock absorbing hub and three in-wheel loops that work as a self-correcting system when encountering uneven ground.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Vibrational Dose Value (VDV)

    Amount of whole body vibration exposure in units of meters/sec to power of 1.75) computed using a 3-axis accelerometer attached to wheelchair on the obstacle course.

    Measured: Baseline Visit (Phase 1 Primary Outcome)

  2. Changes in Neck Pain

    Measured using the Numerical Rating Scale (NRS). The NRS measures amount of pain experienced in a body part over the last 24 hours on a scale of 0 = no pain to 10 = pain as bad as you can imagine.

    Measured: Baseline and 12-weeks (Phase 2 Primary Outcome)

  3. Changes in Upper Back Pain

    Measured using the Numerical Rating Scale (NRS). The NRS measures amount of pain experienced in a body part over the last 24 hours on a scale of 0 = no pain to 10 = pain as bad as you can imagine.

    Measured: Baseline and 12-weeks (Phase 2 Primary Outcome)

  4. Changes in Fatigue

    Measured using the Daily Questionnaire for Pain and Fatigue. Four questions ask specifically about fatigue experienced when using the wheelchair in and outside of the home and on smooth and uneven surfaces. The scale ranges from 0 = no fatigue to 3 = extreme fatigue.

    Measured: Baseline and 12-weeks (Phase 2 Primary Outcome)

Secondary outcomes (1)
  1. Changes in Mobility Participation in the Community

    Measured using Environmental Aspects of Mobility Questionnaire (EAMQ) a 36-item questionnaire accessing frequency of encounters and avoidances to environmental features. Each feature is scored on a 5-point scale (1=never, 2 = rarely, 3 = sometimes, 4=often, 5 = always). A separate total score is determined for Encounters ranging from 21 (never encounters any feature) to 105 (always encounters all features) and Avoidances ranging from 15 (never avoids any feature) to 75 (always avoids all features).

    Measured: Baseline and 12-weeks (Phase 2 Secondary Outcome)

Questions about this trial

What is this clinical trial studying?

A study testing Suspension Wheel in people with Spinal Cord Injuries and Fatigue, run by University of Pittsburgh at 1 site in United States.

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 8 inclusion and 4 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 9 Feb 2024. 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 United States. 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?

Vibrational Dose Value (VDV) (time frame: Baseline Visit (Phase 1 Primary Outcome)). 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Feb 2024.
