Effectiveness of high intensity gait training (HIGT) is supported by the literature. HIGT is defined as 60-80% heart rate reserve for 30-40 minutes performed over ground or on the treadmill. Presently, there is limited evidence investigating clinically feasible treatment strategies to achieve HIGT. This case study’s purpose is to identify clinically feasible interventions to achieve HIGT and promote efficient knowledge translation. The patient was a 23-year-old male with C5 incomplete spinal cord injury presenting with left hemiparesis. Interventions incorporated treadmill training (TT) and over ground training (OGT) for a maximum of 30mins each per session. Strategies included: varying speed; limb weighting; uneven surface gradients; and complex skills training. Results indicate that HIGT is clinically feasible. HIGT was achieved 90.9% of the time with TT vs. 66.7% of the time during OGT. HIGT OGT was accomplished with: running; resisted fast walking; ankle/trunk weighting; and stairs. TT achieved HIGT by: varying speed; increasing gradient; and limb weighting. Harness support would be recommended, as appropriate, to ensure safety and to maximize task demands with both OGT and TT. Future studies with larger sample sizes could provide evidence to identify the most effective training approaches for HIGT and give clearer guidelines to overcome potential clinical barriers to HIGT. To conclude, this case study provided examples of clinically feasible interventions to promote knowledge translation of HIGT.
