GAIT CONTROL USING ROBOTIC HIP EXOSKELETON 2
Executive summary
Biomedical engineering is a multidisciplinary field that plays an essential role in the
combination of engineering principles to the provision of different solutions to healthcare and
medicine. Examples of the critical research areas include kidney dialysis, advanced prosthetics,
artificial organs and the surgical robotics concepts. This research work will be specifically
focused on the utilization of the surgical robotic hip exoskeleton in the improvement of the
efficiency of the metallic gate for the elderly. Robotic exoskeletons have proved to be promising
technologies that can be used effectively in the rehabilitation of the neurological gait (Del-Am et
al., 2014). This research work has focused on the Active Pelvis Orthosis feasibility for the
elderly gait training. Among the ten healthy adult volunteers used in the training procedure for
the APO program, it was noted that they exhibited a tremendous in the level of oxygen
consumption and an approximated value of (−26.6 ± 16.1%). The above results portrayed a
significant improvement in comparison to the cost of metabolism and oxygen consumption for
the other volunteers who had engaged in traditional overground walking. The above findings,
therefore, support the necessitation of the use of exoskeleton in frail individuals' training as
one of the effective strategies that can play a critical role in the practice of aging adults.
Background
A significant portion of the current world population is aging. This, therefore, results in
tremendous challenges to specific global issues for the elderly population (Jimenez et al.,
2012). The aging population is affected by concerns of mobility issues that pose a challenge to
their level of social interaction and is therefore likely to results in sedentary lifestyles. The

concepts of successful or active aging have thus recently emerged as one of the most effective
strategies to help in the improvement of the levels of the lifestyles for the adults (Banala et al.
2008). One of the critical areas for the application of the concept in the research work is the
concept of the use of the robotic exoskeleton in the improvement of the gait efficiency for the
elderly. Exoskeleton robotics can play an essential role in the preservation and the restoration
of mobility in the promotion of independence and the general health of these adults (Del-Am et
al., 2014). They are therefore responsible for the pre-facilitative effects when utilized as
training tools. This poses a tremendous advantage in comparison to the use of the tradition
exercise for the optimization of the training for the adults. Exoskeleton training can enable the
physical practice of adults at much higher velocities. More workloads and volumes can also be
used in exoskeleton training without the need for more efforts from the elderly.
The exoskeleton can, therefore, be utilized in the redefinition of muscular coordination
and the training of different movements. This research work has consequently focused on the
main strategies that can help. The health metric for the energy expenditure is the MCoT
analysis is an effective active strategy for the inventions in the aging strategy. The efficiency
of these aging strategies has been correlated to the quantifiable outcomes and the already set
objectives for aging individuals.
Methodology
A randomized controlled trial plot was conducted on various individuals as an essential
stage of the study. One of the research team members then screened the interested volunteers.
Passing of the screening text guaranteed the participants participated in the entire research
work. An opportunity was given to all the participants to write consents for their agreement in

the participation in scientific research. The approval of the research work was ensured through
consultation with the associated legal protection body (Del-Am et al. 2014). This research
study mainly utilized the elderly individuals and other participants who had specific walking
mobility difficulties. As previously stated, the elderly individuals usually suffer from severe
mobility issues. This can be attributed to the reduced body strength in their limbs that affects
their mobility effectiveness. The use of the robotic exoskeleton is therefore very useful in the
provision of aid that can quickly help them walk with minimal difficulties.
This research work has focused on different tests that have investigated the
effectiveness of the robotic-assisted four-week training process that is focused on the provision
of the solution to the problem of mobility evident among most of the adult population. This
research work was conducted with the utilization of ten random adults who were subjected
both traditional aided walking exercise and robotic-aided walking exercise (Banala et al. 2008).
The training strategy that was used as an integrated mechanism in providing the combination
of the elements in strength training of the walking exercise on the brisk treadmill (Low 2011).
This part o the practice used the hip skeleton that was powered and referred to as the Active
Pelvis Orthosis (APO). The production of this exoskeleton aided exercise was achieved
through the use of the torque profile that was gait modulated. The robotic exoskeleton design
employed the use of torque profile design for the hip extensors enhancement that plays an
essential role in the provision of assistance to the hip flexor at the conditions of the swing of
the participants. This was very effective in helping towards the general reduction of the
walking costs of the elderly participants (Jimenez et al. 2012). The robotic exoskeleton was
also employed to assist in the general reduction the level of the oxygen intake for these
different participants used in the study. The profile for the combined-assistance facilitated the
