Table 2: Demands of Hydroplane Racing
| Description of Sport |
Hydroplane racing involves riding small, motored boats across a lake along courses and in straight lines for speed. Participants kneel in a crouched position behind the steering wheel and utilize their lower extremities to absorb shock and guide the boat across wake in the water. Various classes exist, including technical classes that emphasize change of direction and controlled maneuvering, as well as straight line racing. Racers attain speeds of up to 50 MPH while racing. |
| Shoulder |
Active shoulder flexion range of motion of 160o is preferred. Sustained pressure needs to be maintained on steering wheel therefore adequate shoulder and upper arm strength is required. |
| Trunk Stabilizers |
Adequate trunk stabilizer strength is a key component to maintaining balance while utilizing arms to stabilize the boat and legs to control for unpredictable changes from the boat. |
| Hip |
Need to be able to maintain crouch position with hips approximately in line with knees in the sagittal plane. (Hip flexion > 125°, knee flexion >130° pending limb girth) Minimum of 5/5 hip strength in all directions with manual muscle testing. |
| Knee |
In order to assume proper crouch position in boat, a minimum of 130o of knee flexion is required. Quadriceps strength is extremely important to maintain proper position. |
| Foot/Ankle |
Full closed chain dorsiflexion is required to maximize success. |
| Balance |
Racers are commonly barefoot or wear minimalist shoe apparel and need to be able to balance on a boat changing direction and adjust various wakes in the water. |
MPH: miles per hour

PROM: passive range of motion; AROM: active range of motion; MMT: manual muscle testing; HS: hamstring. *Range of motion shorthand interpretation. The first number refers to the knee extension value, and the second number refers to the knee flexion value. For a ROM assessment of 3-75, this can be interpreted as the subject lacking 3° of knee extension and only yielding 75° of knee flexion. A reading of 3-0-120 would indicate that the subject has hyperextension of the knee by 3° and 120° of flexion.

The interventions started with a static tuck on a solid surface, and as he gained confidence, the patient was challenged to perform weight shifting and upper extremity motions such as rowing and shoulder extension while in a tuck. This replicated an unstable surface similar to what he dealt with while racing over water, and he progressed from static holds to weight shifting and reaching while on the BOSU. By modifying equipment in the environment, the therapeutic alliance was once again enhanced, and helped to build confidence that when he completed the rehabilitation process he would be safe to boat again.
