“…Some studies have used the coefficient of variation (CV) of the weight displacement as a measure of postural sway [35,36]. Tremor can also be assessed in the 8 Hz band [37] for the variation of movement on the platform [11,38]. The most often encountered tremors have frequencies between 4 and 12 Hz.…”

Plantar fasciitis (PF) is a common condition found in men and women and can reoccur throughout life. PF is commonly diagnosed by prolonged foot pain lasting more than 3 months and a plantar fascia over 0.4 mm thick, as measured using ultrasound imaging. This study examined the ability to balance and the occurrence of muscle tremor during different balance tasks in patients with PF compared to their control counterparts. Fifty subjects (25 patients with PF and 25 control subjects) participated in this study. Subjective pain (measured with a visual analog scale (VAS)), pressure pain threshold (PPT), and postural sway and tremor during eight different balance tasks were measured. Postural sway was measured by a balance platform, while tremor was measured as the mechanical movement of the platform in the 8 Hz frequency range. Thickness of plantar fascia, subjective pain, and PPT were significantly greater in the PF group compared to the controls (p < 0.001). Postural sway and 8 Hz tremor were significantly greater in the PF group compared to the control group for all eight balance tasks (p < 0.01). These results indicate that the lack of plantar fascia elasticity is probably the cause of the reduced balance and increased muscle tremor.

The laparoscopic approach is widely used in abdominal operations, and has replaced open surgery as the standard approach for a number of procedures. Performing operations laparoscopically has multiple benefits for patients including reduced postoperative hospital stay, cosmetic benefits, and generally reduced postoperative pain 1) -3) . In laparoscopic surgery, trocars are placed through the abdominal wall and carbon dioxide gas is insufflated to develop a pneumoperitoneum. The insertion of instruments through ports can cause surgeons to have their upper extremities raised for extended periods of time. Since instrument manipulation is limited by the position of the trocar, the procedure can be difficult 4) . Laparoscopic surgery can be time-consuming, with an increased physical burden on the surgeon. The operating room environment is not always a comfortable setting for the surgeon, and many surgeons complain about the physical burden of performing surgery 5) ,6) . Repeated muscle fatigue in the upper extremities can lead to work-related musculoskeletal disorders of the elbows and wrists, which may affect the ability to perform surgery 7) .

Differential analysis of muscle fatigue induced elbow and wrist tremor in controlled laparoscopic manoeuvring

Abstract: In this work, we have investigated the attribution of elbow and wrist joints in FIT during laparoscopic tool manipulation. The outcomes may be useful for the design of robot-assisted surgical manipulator, and can be used for quality assessment of surgical training as well.
