| Label | Type | Description | Intervention Names |
|---|---|---|---|
| AFES and RMT Paraplegia Group | Experimental | Patients with a diagnosis of paraplegia will receive co-treatment with abdominal functional electrical stimulation (AFES) and respiratory muscle training (RMT) for 2 weeks. |
|

| Xcite Clinical Station | Device | The abdominal functional electrical stimulation (AFES) will be conducted using the Xcite system. This is a battery-powered stimulator with up to 12 channels of cyclical stimulation. It is a task-specific modality to enhance mass practice during neurological re-education. The electrical stimulation will be applied to the abdominal and back muscles. In addition, participants will receive two specific respiratory muscle training exercises performed 3 days per week. |
| Measure | Description | Time Frame |
|---|---|---|
| Percentage change in peak cough flow (PCF) | Assessing the percentage change in peak cough flow as assessed by peak expiratory flow meter with a pillow face mask. | one week pre-intervention and up to 4 weeks post-intervention |
| Percentage change in peak expiratory flow | Assessing the percentage change in peak expiratory flow as assessed by peak expiratory flow meter with a pillow face mask. | one week pre-intervention and up to 4 weeks post-intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Percentage change in forced expiratory volume in 1 second (FEV1) | Assessing the percentage change in forced expiratory volume in 1 second (FEV1) as measured by the spirobank II. Measured in Liters/minute. | one week pre-intervention and up to 4 weeks post-intervention |
| Percentage change in forced vital capacity (FVC) |

Assessing the percentage change in forced vital capacity (FVC) as measured by the spirobank II. Measured in Liters/minute. |
| one week pre-intervention and up to 4 weeks post-intervention |
| Percentage change in maximum inspiratory pressure (MIP) | Assessing the percentage change in maximum inspiratory pressure (MIP) as measured by the MicroSpiro. Measured in Liters/minute. | one week pre-intervention and up to 4 weeks post-intervention |
| Percentage change in maximum expiratory pressure (MEP) | Assessing the percentage change in maximum expiratory pressure (MEP) as measured by the MicroSpiro. Measured in Liters/minute. | one week pre-intervention and up to 4 weeks post-intervention |
| Change in cough effectiveness as measured by Likert Scale | The 5-point Likert scale will be used to obtain a self-rated perception of cough effectiveness. The participant will be asked to rate how strong and how well secretions were cleared after coughing. The rating scale will range from 1=very poor; 2=poor; 3=fair, 4=good; 5= very good. A score of 4 or 5 is classified as effectively clearing secretions after coughing. | one week pre-intervention and up to 4 weeks post-intervention |
