Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Range of scapular downward rotation | Measured during gait assessment on post-operative day 4-12 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Bilateral upper extremity kinematics | Measured during gait assessment on post-operative day 4-12 | Hip flexion/extension, knee flexion/extension, and ankle dorsiflexion/plantar flexion; measured through optical motion tracking software |
| Bilateral upper extremity electromyographic (EMG) activity | Measured during gait assessment on post-operative day 4-12 | — |
| Upper extremity pain | Measured at 3 time points: pre-operative, during gait assessment, and 4 weeks post-operative | Measurements of pain at the shoulder, elbow, and wrist using an 11-point Numerical Rating Scale (0 = no pain, 10 = extreme pain) |
Other
| Measure | Time frame | Description |
|---|---|---|
| Weight-bearing lower extremity kinematics | Measured during gait assessment on post-operative day 4-12 | Hip flexion/extension, knee flexion/extension, and ankle dorsiflexion/plantar flexion; measured through optical motion tracking software |
| Number of falls | Measured at 4 weeks post-operation | — |
| Torso kinematics | Measured during gait assessment on post-operative day 4-12 | Thoracic flexion/extension; measured through optical motion tracking software |
| Spatiotemporal parameters | Measured during gait assessment on post-operative day 4-12 | Gait velocity, crutch stride length, weight-bearing lower extremity stride length; measured through timing lights and computer software |
| Crutch comfort | Measured during gait assessment on post-operative day 4-12 | Measured through an 11-point Numerical Rating Scale for both crutch types (0 = extremely uncomfortable, 10 = extremely comfortable) |
