“…These heavier posterior borne loads may elicit a different biomechanical response than evident with the currently chosen load configurations, particularly when crossing an obstacle. As such, further research is needed to determine if these heavier, posterior borne loads result in biomechanical adaptations that subsequently increase the risk of suffering a trip-related fall when a soldier is on duty, particularly as they fatigue (Kesler et al, 2016). The current sample size may also be a limitation of the study.…”

Soldier-relevant body borne load impacts minimum foot clearance during obstacle negotiation

Soldiers often trip and fall on duty, resulting in injury. This study examined ten male soldiers' ability to negotiate an obstacle. Participants had lead and trail foot minimum foot clearance (MFC) parameters quantified while crossing a low (305 mm) and high (457 mm) obstacle with (19.4 kg) and without (6 kg) body borne load. To minimize tripping risk, participants increased lead foot MFC (p = 0.028) and reduced lead (p = 0.044) and trail (p = 0.035) foot variability when negotiating an obstacle with body borne load. While obstacle height had no effect on MFC (p = 0.273 and p = 0.126), placing the trail foot closer to the high obstacle when crossing with body borne load, resulted in greater lead (R = 0.640, b = 0.241, p = 0.046) and trail (R = 0.636, b = 0.287, p = 0.048) MFC. Soldiers, when carrying typical military loads, may be able to minimize their risk of tripping over an obstacle by creating a safety margin via greater foot clearance with reduced variability.

“…During the walking process, falls may occur due to having less that the minimum required clearance between the foot and the obstacles [ 49 , 50 , 51 , 52 ]. To control the foot clearance and avoid tripping, a virtual repulsive force is used to help the exoskeleton robot adjust the foot clearance.…”

Tripping is a common problem that everyone faces when walking. This paper mainly focuses on a lower limb exoskeleton that can help those weak in joints to avoid tripping when negotiating stairs or stepping over obstacles. This method does not need a camera or map reconstruction to recognize the obstacles and plan paths. The exoskeleton applies an impedance controller to follow and control the pilot’s movements. A virtual potential field is proposed to help the robot regulate the pilot’s motion and avoid kicking the obstacles appearing in front of the pilot’s foot during walking. Simulation and experiments show that this method works effectively and could help the elderly and those affected by joint weakness avoid tripping when walking.

“…For all the above-mentioned reasons, several studies deal with the analysis of physiological variables [6, and physical parameters [88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104][105][106][107]. Sensor-based systems, such as portable metabolic systems, heart rate monitors, ingestible temperature pills and skin temperature patches for the physiological aspects [6,25,46,48,53,[55][56][57]71,74,78,81,84], as well optoelectronic systems, inertial sensors and pressure insoles for the physical ones [94][95][96][97][98]101,102,108,109] have shown their potential mainly due to the possibility to measure several variables without influencing the FF working procedures.…”

In recent years, the necessity to prevent work-related diseases has led to the use of sensor-based systems to measure important features during working activities. This topic achieved great popularity especially in hazardous and demanding activities such as those required of firefighters. Among feasible sensor systems, wearable sensors revealed their advantages in terms of possibility to conduct measures in real conditions and without influencing the movements of workers. In addition, the advent of robotics can be also exploited in order to reduce work-related disorders. The present literature review aims at providing an overview of sensor-based systems used to monitor physiological and physical parameters in firefighters during real activities, as well as to offer ideas for understanding the potentialities of exoskeletons and assistive devices.
