To create a comprehensive definition of the MWC propulsion cycle and demonstrate its clinical benefit. |
n=54 (44 men and 10 women); Mean injury time: 14.4 years (±10.4); Mean age: 40.7 years old (±11.3); Bodyweight: 76.6 kg (±16.4) |
Kinetic and kinematic data were collected during MWC propulsion on the dynamometer. |
The propulsion cycle was divided into: contact phase (initial contact, propulsion, and release) and recovery phase; The initial contact and release periods were considered as non-propulsive moments of the hand's contact with the rim; The loss of power and the increase in the braking moment occurs as the impulse speed increases during the initial contact and release periods; The use of a propulsion pattern with the hands below the rim during the initial contact period decreasing the braking moment and increasing power. |

To determine whether the magnitude of the hand/forearm speed and the reaction force depends on the propulsion technique. |
n=34 (31 men and 3 women); Mean injury time: WD; Mean age: WD; Mean body weight: 74.5 kg (±12) |
Kinetic and kinematic data were collected during the MWC propulsion on the stationary ergometer. |
Participants with paraplegia preferably used the SLOP standard in comparison to other standards (ARCH and SC); The speed of the hand/forearm before contact with the rim was correlated with the effective force during propulsion; There was no correlation between the reaction force and the propulsion patterns. |

To investigate the relationships between the location of the hand in the periods of initial contact and release, and propulsion characteristics, reaction forces, and shoulder kinetics during propulsion. |
n=222 (198 men and 24 women); Mean injury time: 9.3 years (± 6.1); Man age: 34.7 years old (± 9.3); Mean body weight: 74.4 kg (±15.9)
|
Kinetic and kinematic data were collected during MWC propulsion on the stationary ergometer. |
PCA and ARA of the hand reduced cadence and greater distance between cycles. Only ARA was associated with increased speed; ARA increased forces in the rim and over the shoulder as well as in the moments of adductors and external rotators; The PCA increased the posterior strength and shoulder flexor moments. |

To evaluate the effect of backrest height on kinematics and kinetics during propulsion. |
n= (26 men and 10 women); Mean injury time: 11.88 years (±8.4); Man age: 39.1 years old (±10.5); Mean body weight: WD |
Kinetic and kinematic data were collected during MWC propulsion on the motorized treadmill in level or inclined condition (3rd), using a low or high backrest. |
The use of the low backrest allowed greater shoulder ROM, reduced cadence and increased angle, and impulse time, regardless of the leveling or inclination of the treadmill. |

To determine predictors of shoulder joint pain in people with paraplegia. |
n= 223 (198 men and 25 women); Mean injury time: 9.3 years (±6.2); Man age: 34.7 years old (±9.3); Mean body weight: 74.1 kg (±16.3) |
Participants were assessed for shoulder pain for 3 years using WUSPI. Daily activity variables (mean speed and propulsion distance; transfer and sports participation) and shoulder torque variables were measured. |
Among 201 participants, 39.8% developed shoulder pain. The daily activity variables and the baseline maximum isometric torque were lower in those who developed shoulder pain. The adduction torque of the shoulder was considered a predictor of pain onset. However, none of the factors were considered to be strong predictors of shoulder pain. |

To determine how MWC users modify the UL mechanics as the propulsion speed increases. |
n=40 (32 men and 8 women); Mean injury time: 8.25 years; Man age: 35 years old; Mean body weight: 74.5 kg (±18) |
The UL kinematics and the reaction forces generated in the rim were measured during the propulsion of free and fast speed in the stationary ergometer. |
The increase in the propulsion speed reduced the contact time with the rim and increased the magnitude of the reaction forces; The magnitude of the shoulder moment does not necessarily correspond to the increase in speed, but it can be changed according to the UL orientation. |
