This pilot A-B study aims to develop and validate personalized training programs for older adults with decreased mobility on a Semi-Reclining Intelligent Stationary Bike prototype.

The study also aims to assess the feasibility and acceptability of the training programs and to document their preliminary effects on physical health, perceived well-being, and quality of life. Ten participants will take part in five personalized training sessions with the intelligent bike and five standard training sessions with a traditional stationary bike.

An intelligent stationary bike prototype (iBike) is being developed to evaluate the lower limbs' function during pedaling. The iBike uses artificial intelligence to prescribe personalized training programs based on individual pedaling data. This pilot study aims to develop the training programs, validate their prescription by the iBike, and assess their feasibility, acceptability, and preliminary effects on physical health, perceived well-being, and quality of life in older adults with decreased mobility.

First, the iBike training modules will be developed through a thorough literature review, and prescription criteria will be identified based on the users' pedaling and clinical data as well as expert opinion. Second, 10 participants' lower limb function (i.e. strength, range of motion, coordination and endurance) will be evaluated by the iBike during active and passive pedaling. The evaluation results will be used by the iBike to prescribe a personalized training program. Expert clinicians will also be provided with the ibike evaluation data and will be asked to recommend a personalized exercise program for each participant based on their data. The iBike's prescription of training programs will be validated by comparing it with that of expert clinicians. Third, the feasibility, acceptability, and preliminary effects of the iBike training programs on mobility, physical health, perceived well-being, and quality of life will be assessed through ten training sessions (twice weekly for 45 minutes) with ten older adults using an A-B study design. During the A and B phases, participants will undergo training with either the iBike or a conventional stationary bike.

Ultimately, the goal is to deploy and test this technology in various living spaces and rehabilitation environments to demonstrate its benefits on the physical activity level of healthy older adults and those with mobility problems.
