Background and Purpose: Several studies that compare open and laparoscopic procedures have demonstrated that the minimally invasive surgeon has greater musculoskeletal pain when compared with open surgeons. The purpose of our study was to demonstrate whether the use of the gel mat in the endoscopic setting offered any ergonomic benefit to the surgeon. Materials and

Methods: One hundred endoscopic procedures, by 11 different surgeons, were randomized intostudy (use of a gel mat) and control groups. Procedures included both percutaneous nephrolithotomies and ureteroscopies and were randomized without regard to the type or expected length of the procedure. All subjects completed a preoperative, intraoperative, immediate postoperative, and 24-hour postoperative questionnaire. During the procedures, an independent observer recorded the number of intraoperative stretches and positional changes because of discomfort.

Results: The mean preoperative metrics for the gel mat and no gel mat groups were similar with the exception of the ≤60-minute group, whose members found the gel mat group starting with greater overall discomfort (1.7 vs 1.3, P=0.0273). In the ≤60 minute group, gel mat use significantly decreased postoperative discomfort (P=0.0435) and improved postoperative energy (P=0.0411). In those procedures >60 minutes, the gel mat improved postoperative discomfort and energy as well as the number of stretches and postural changes during the procedure.

Conclusion: Application of gel mats in the endoscopic setting improves surgeon overall postoperative discomfort and energy in all cases. For cases >60 minutes duration, gel mats also decrease the number of stretches and postural changes from discomfort. Some of these salutary effects may translate into more efficient surgery and better patient outcomes.

Re: Gel mats in the OR lessen fatigue and improve energy

Effects of anti-fatigue mats on perceived discomfort and weight-shifting during prolonged standing.
Wiggermann N, Keyserling WM.
Hum Factors. 2013 Aug;55(4):764-75.

OBJECTIVE:
The aim of this experiment was to investigate the effects of anti-fatigue mats on perceived discomfort and behavioral responses (weight-shifting between the feet) during prolonged standing.
BACKGROUND:
Prolonged standing is a common requirement in the workplace and is a well-known cause of discomfort. Anti-fatigue mats have been shown to reduce discomfort resulting from standing, but no study has identified a particular mat that performs better than others or examined the relationship between discomfort and weight-shifting.
METHODS:
Participants stood for 4 hours on four commercially available "anti-fatigue" mats and a hard surface (control condition). Subjective ratings of discomfort were measured, and in-shoe pressure was recorded and used to evaluate weight-shifting during standing.
RESULTS:
Compared to the control condition, after 4 hours of standing discomfort was reduced by three of the four mats, but discomfort ratings did not significantly differ among mats. However, significant differences among mats were found in the frequency of weight-shifting, and weight-shifting was positively correlated to discomfort.
CONCLUSION:
These results suggest that subjective reports of discomfort were not sufficiently sensitive to detect differences among mats for the experimental conditions tested. Behavioral responses, specifically weight-shifting between feet, may provide a more sensitive alternative to subjective reports.

Do Portable Anti-Fatigue Mats Affect the Mechanics or Discomfort of Walking
André Gauvin
Thesis; University Sudbury, Ontario, Canada; 2016

Prolonged periods of standing and walking creates loading on the muscles of the back and legs
causing pain and discomfort to many employees who stand on hard surfaces such as cement floors.
Portable anti-fatigue mats are an ergonomic intervention that is thought to be a solution for
musculoskeletal injuries. Thirteen healthy subjects ranging from 18-55 years of age were recruited
for the study to represent a working population. Subject completed two 3 hour sessions, one with
work boots, and the other with the combination of work boots and portable anti-fatigue mats.
Subjects walked for a 3 hour period to simulate a prolonged walking period. Participants were
instrumented with reflective marker to collect kinematic data and walked on the force plate to
collect kinetic forces acting on the body. They also completed a discomfort questionnaire for “pre”,
“during” and “post” exercise. Results showed no significant differences in mechanical variables,
and showed significant differences in discomfort ratings for the ankle/foot and knee between
conditions; while showing significant differences for the ankle/foot and low back over time.

Anti-fatigue mats can reduce low back discomfort in transient pain developers
Taylor B Winberg et al
Appl Ergon. 2021 Nov 24;100:103661

Complaints of musculoskeletal pain are common among employees who stand for prolonged periods. This study sought to determine if an anti-fatigue mat (AFM) could uniquely affect low back pain (LBP), low back posture, and foot-floor interface responses in individuals prone to developing LBP (termed pain developers (PDs)) during prolonged standing experiments compared to those who do not develop LBP under the same exposures (termed non pain developers (NPDs)). Sixteen volunteers (8 PDs and 8 NPDs) were recruited based on their pain-development tendencies, which were established in previous standing experiments. They visited the laboratory on two separate days for 60 min of light manual work while standing on either a rigid floor or AFM. All participants were asymptomatic at the beginning of each experimental session. The amount of LBP experienced during the standing exposure, measured via a visual analogue scale, was reduced (p = 0.03) in the PD group when on the AFM (3.6 ± 6 mm) compared to the rigid floor (6.8 ± 7 mm). LBP levels remained low and unchanged (p = 0.5) between the AFM (2.4 ± 5 mm) and rigid floor (1.6 ± 2 mm) conditions for the NPD group. Neither postural nor foot-floor interface measures correlated with this unique reduction of LBP for the PD group when standing on the AFM. The AFM did, however, increase centre of pressure excursion (NPD 55% increase; PD 35% increase) and tended to increase the number of body weight shifts (NPD 116% increase; PD 54% increase) in both the PD and NPD groups. These findings suggest that AFMs may selectively benefit individuals prone to developing standing-induced back pain by facilitating subtle movements at the foot-floor interface.
