Post-stroke recovery depends on, a) motivation for physical exercises and b) trained therapists. The objective of the study was to examine the effect an exergame with a religious ritual as gameplay theme has on the motivation for lower limb motor therapy. Two games were designed and developed, a ‘temple game’ simulating the 2400 odd steps to reach the sanctum of a famous deity located in India and a ‘trekking game’ with similar setup sans the religious symbols. A gym stair-stepper equipment was fitted with sensors to detect the action of climbing. Each physical step-action is mapped to a corressponding step in the virtual game. Data were collected from 4 stroke patients, 1 spinal cord injury patient and 13 healthy male participants. Motivation/immersion difference between the two games was compared. The post-test game experience questionnaire scored higher on immersion, motivation, and interest for the temple game. A remotely accessed and controlled exergame is considered important for doctors and patients due to the acute shortage of trained therapists. The findings open up a new genre of exergaming for neurorehabilitation customized to personal belief/faith structures. The authors do not propagate or promote any religious beliefs (+positive or −negative) but have sourced an existing belief system to build assistive devices for stroke rehab.
