Clinical Trial Summary

The overall purpose of this project is to test the feasibility of a manual wheelchair propulsion program which aims to reduce the chance of development of upper limbs pain and injury.

Description:

The purpose of this project is to develop a feasible wheelchair propulsion training that can fit into an in-patient rehabilitation schedule, and determine the effectiveness of the training protocol. This project consists of a randomized control trial (RCT) for manual wheelchair users (MWUs) that examines the number of manual wheelchair propulsion repetitions required to produce change. For the RCT, we will recruit twenty individuals who use manual wheelchairs as their primary means of mobility and who do not follow the recommended clinical guidelines for propulsion. Participants will be randomized into two independent groups: motor learning repetitions overground (Training Group; n =10), and general education on recommended propulsion techniques (Education Group; n =10). Demographics, cognition, shoulder strength, participation, and wheelchair seating may only be assessed at baseline. Participants then may be assessed from the kinematics of their wheelchair performance overground and on a motorized treadmill. Participants may be tested on their wheelchair propulsion techniques in and outside of the lab, upper extremity pain at baseline, post-intervention, and three-week follow-up; participants may also be asked qualitative questions regarding the intervention experience, the experience with the equipment and the laboratory research, the monitoring setting, and the general experience with the research study.

The primary research question is that will repetition of proper propulsion technique practiced overground result in improved manual wheelchair propulsion biomechanics?

Intervention

Behavioral:
• In-person wheelchair propulsion training program
The wheelchair propulsion (WP) intervention is based on our previous pilot work and the best available evidence on WP training. The CPGs recommend minimizing the force and frequency of pushes while using long strokes during propulsion. Each training session will include massed practice with repetitions overground. Each session is organized to limit the number of variables (i.e., long push strokes and dropping the hands down below axle) presented to the participant at one time. Propulsion Set A will focus on using longer push strokes. Propulsion Set B will focus on dropping the hand down toward the axle. Propulsion Set C will focus on both A and B.
• 30-minute education session
Both groups will receive a 30-minute education session regarding the CPGs. This education session will follow the instructions provided in Rice and colleagues. (L. A. Rice et al., 2014). It consists of the importance of practicing biomechanical efficient propulsion. The material lists out the consequences and the impact of upper limb pain and injury. It provides a detailed step by step on how to propel properly. They will view the video that shows the biomechanics of efficient and inefficient propulsion.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Motion capture - changes in push angle	Push angle during the push phase of propulsion is assessed with video motion capture (VMC). The VMC system consists of 14 Vero 2.2 digital cameras to detect the location of the reflective markers, specifically on the shoulder, elbow, and wrist. The 3D infrared coordinates will be recorded while participants propel their wheelchair over the ground and on a dynamic roller system. Push angle will be calculated by finding the inner product of the vectors formed by the elbow-shoulder and elbow-wrist. The push angles will be compared across the three testing sessions. This variable corresponds to the recommendations outlined in the clinical practice guidelines. We hypothesize that the increase of push angle will be greater in the training group than the control group.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
Primary	Motion capture - changes in hand-axle distance	Hand-axle distance during the recovery phase of propulsion assessed with video motion capture (VMC). The VMC system consists of 14 Vero 2.2 digital cameras to detect the location of the reflective markers, specifically on the axle and the third metacarpal joint. The 3D infrared coordinates will be recorded while participants propel their wheelchair over the ground and on a dynamic roller system. Hand-axle distance will be calculated by the magnitude of the vector formed by the third metacarpal joint and the axle. The hand-axle will be compared across the three testing sessions. This variable corresponds to the recommendations outlined in the clinical practice guidelines. We hypothesize that the increase of hand-axle distance will be greater in the training group than the control group.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
Primary	Wheelchair Propulsion Test (WPT) - changes in effectiveness	The WPT assesses wheelchair mobility and performance of manual wheelchair users (MWU). The WPT requires MWU to propel using a self-selected natural velocity across 10 meters of a smooth flat surface from a static start. The number of pushes and the time will be recorded. The effectiveness of the propulsion is the displacement per push and will be calculated by the 10 meters divided by the number of pushes. We hypothesize that the increase in the effectiveness of propulsion will be greater in the training group than the control group.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
Primary	Wheelchair Propulsion Test (WPT) - changes in cadence	The WPT assesses wheelchair mobility and performance of manual wheelchair users (MWU). The WPT requires MWU to propel using a self-selected natural velocity across 10 meters of a smooth flat surface from a static start. The number of pushes and the time will be recorded. The cadence of the propulsion is the number of push per second and will be calculated by the number of push divided by the time spent finishing the 10-meters line. We hypothesize that the decrease of cadence will be greater in the training group than the control group.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
Primary	Wheelchair Propulsion Test (WPT) - changes in propulsion pattern	The WPT assesses wheelchair mobility and performance of manual wheelchair users (MWU). The WPT requires MWU to propel using a self-selected natural velocity across 10 meters of a smooth flat surface from a static start. The number of pushes and the time will be recorded. Clinicians will also record whether"during the contact phases, did the subject generally begin the contact between the hands and the hand-rims behind the top dead center of the rear wheel?", and " during the recovery phases, did the subject generally use a path of the hands that was predominantly beneath the handrims?" The clinician will provide his/her evaluation by answering the two questions. It is expected that after the training, the subject will change his/her pattern from both "no" to both "yes". These two questions are based on the clinical practice guidelines (CPG) and only when both answers are "yes", then the participant will be considered following CPG.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
Primary	Outdoor propulsion - ratio of efficient propulsion pattern	During the outdoor propulsion session, participants will push their wheelchair in an outdoor, asphalt surface parking lot with no ceiling for approximately three to five minutes across approximately 200 meters. The parking lot consists of 5°-10°slopes, a flat surface with small potholes, and two small bumps/thresholds. Participants will be told to propel their wheelchair at their regular speed in the parking lot. An experimenter will follow the participant with a body harnessed action camera to record participant's left side propulsion. A video coder will be viewing the recording then judge whether each push with the two questions mentioned in WPT form. The changes in propulsion patterns will be calculated by the amount of CPG-based propulsion divided by the total amount of propulsion. We hypothesize that the ratio increases of the CPG-based propulsion will be greater in the training group than controls.	Baseline, 3-week after baseline for the control group/immediate after training group intervention, 3-weeks after second assessment
