stage. Wind driven clouds bump into the balloon and move the balloon arbitrarily

which the patient has to counteract with trunk movements.

Therapy Game 3: Sunrise

This experience is based on simple shoulder flexion. The patient holds their arms

out straight in front of them and raises their arms up and over their head in a motion

that ideally, is pure shoulder flexion with a maximum, healthy ROM of 180 degrees.

This exercise may be done passively with HCP assistance or actively by the patient

themselves.

When this motion is initiated, a Sun character rises up from beyond the horizon in

proportion to the patient’s shoulder flexion ROM. The sun also rotates in the sky

and translates side to side, depending on the patient’s postural symmetry. When the

patient’s arms are horizontally and vertically symmetric, and their torso is in vertical

alignment with their pelvis and head, the sun will be smiling broadly and high in the

sky straight ahead of the patient.

If the patient’s posture exhibits asymmetry or other compensating characteristics,

the sun’s position and the expression on its face will alter from the “ideal” state,

thereby providing the patient an external visual cue as to their posture, and allowing

them to learn via alternative references, what is proper, non-compensating posture.

Maximum shoulder flexion ROM achieved during this experience will be stored as a

session output for the HCP’s record.

Sub-Activity 1: Sunrise

As the patient fully lowers and fully raises their arms to the best of their ability, the

lighting in the virtual world will exhibit night-time or daytime according to the sun’s

position, thus greatly accentuating the experience and feedback of a simple coordi-

nated arm raise.

Sub-Activity 2: Harvest

The Bumper Crop sub-activity involves growing a variety of vegetables by raising

and lowering ones arms a number of times in order to trigger the appearance of day-

night cycles. Different numbers of cycles necessary to fully grow a vegetable can be

controlled by the HCP through difficulty settings. Upon full growth of each veg-

etable, the patient receives an award that is saved in their game record. This activity

creates an incentive for the patient to do multiple repetitions of this exercise if called

for by the patient’s rehabilitation plan.
