The effect of joystick handle size and gain at two levels of required precision on performance and physical load on crane operators
Article Abstract:
A study was designed to determine the effect of joystick handle size and gain at two levels of required task precision on performance and physical load on eight experienced crane operators. Data recommended a joystick with a short handle, leading to an increased performance whilst the operator's physical load decreased or remained the same, thus indicating that further optimization of performance and physical load could be achieved by optimizing gain settings of the joystick in relation to the task and type of joystick used.

Effect of joystick stiffness, movement speed and movement direction on joystick and upper limb kinematics when using hydraulic-actuation joystick controls in heavy vehicles
Article Abstract:
A study is conducted to quantify and compare the effects of three hydraulic-actuation joystick kinematics as an initial step towards the development of hydraulic-actuation joystick design protocol. The findings of this study show that joystick stiffness and speed alternations affect joystick and upper limb kinematics minimally.

The effects of shoulder load and pinch force on electromyographic activity and blood flow in the forearm during a pinch task
Article Abstract:
The effect of static contraction of proximal musculature on the blood flow more distally in the upper extremity is investigated. The results have shown that shoulder load might influence blood flow to the forearm.
