Cataract phacoemulsification performed by resident trainees and staff surgeons: intraoperative complications and early postoperative intraocular pressure elevation.

PURPOSE: To determine the incidence of intraoperative complications of phacoemulsification cataract surgery in a teaching hospital and to compare the intraoperative complication rate between resident trainees and staff ophthalmologists, to ascertain the overall rate of intraocular pressure (IOP) elevation on postoperative day 1 (POD1), and, again, to compare this value between resident trainees and staff surgeons. SETTING: Centro Hospitalar São João, Oporto, Portugal. DESIGN: Retrospective study. METHODS: This study included eyes submitted for phacoemulsification cataract surgery from January 1, 2017, to December 31, 2017. There were no exclusion criteria. Data collected included the type of surgeon, level of resident training, case complexity, and intraoperative complications. From all noncomplicated surgeries, preoperative IOP and IOP-POD1 were collected. RESULTS: A total of 2937 surgeries were included; 25.6% were performed by resident trainees. The complication rate was 6.3% with resident trainees and statistically significantly lower (3.3%) in staff surgeons. The complication rate of resident trainees did not differ according to their level of residency. There was a significantly increased incidence of IOP-POD1 elevation in the resident trainee group compared with the staff surgeon group. Surgeries performed by resident trainees, a preexisting history of glaucoma, and pseudoexfoliation were significant risk factors for IOP elevation. CONCLUSIONS: To our knowledge, this is the first European study comparing the incidence of intraoperative and postoperative complications in cataract surgery performed by resident trainees and staff surgeons. We report a significantly higher rate of intraoperative complications and IOP elevation on POD1 in resident trainees vs staff surgeons.

[Virtual simulation for learning cataract surgery]. / Simulation virtuelle pour l'apprentissage de la chirurgie de cataracte.

INTRODUCTION: The training in phacoemulsification cataract surgery in our context requires a long learning curve for a novice surgeon starting from the observation period to the realization of the different operating stages being supervised by a senior surgeon, all under stressful conditions. Topical or locoregional anesthesia limits the communication in the operating room between the novice surgeon and his mentor; thus, increasing the risk of having more operative complications. To reduce the teaching time of cataract surgery, our department has introduced virtual simulator trainings for phacoemulsification. PURPOSE OF THE STUDY: To assess the impact of surgical simulator training on residents' performances. MATERIAL AND METHODS: We conducted a prospective comparative study in our department in partnership with a private ophthalmology clinic where the simulator is installed. Twelve residents were included in this study, six of them were randomly selected to participate in the phacoemulsification surgical simulator training while the others never used the simulator. The training lasted 30 hours in total. No residents had previous training in phacoemulsification. The parameters studied were: the operating time, the achievement of a circular capsulorhexis of 5-6mm in diameter and well centered, the number of capsular breaks with or without an anterior vitrectomy and finally the accumulated dissipated energy (EDC). The cataract surgery was performed on an Alcon Centurion platform. RESULTS: In the operating room, each resident operated 25 cataracts; we compared the two user groups including the simulator and non simulator user and we noticed a statistically significant difference (P<0.05) in terms of average operating time respectively 20 minutes and 37 minutes. Regarding the realization of capsulorhexis; 22 cases of rhexis wandering and 12 poorly centred rhexis on 150 operated cataracts were identified (22.7%) in the group of residents who received no simulator training versus 10 cases in the simulator user group (6.7%). The cumulative dissipated energy (EDC) was significantly lower in the simulator user group (8.1 versus 18.7). The same is true for the rate of posterior capsular rupture, which is higher in the non-user group of simulator 37 cases (24.6%) versus 10 cases (8%) in the second group. DISCUSSION: Ophthalmic surgery has benefited from the introduction of endo-ocular surgical simulation tools through simulators of vitreoretinal surgery and phacoemulsification; whose main role is primarily pedagogical because a simulator allows young residents to acquire dexterity and autonomy over a shortened period of time in addition to minimizing the risk of complications. CONCLUSION: Initial learning of phacoemulsification cataract surgery should be an integral part of the virtual simulator program before moving to the real conditions of the operating room as it allows for better operative performance with a minimal complication rate.

Postoperative Blepharoptosis After Modern Phacoemulsification Procedure.

PURPOSE: To investigate the frequency of transient (1 month) and persistent (at least 6 months) postoperative ptosis following clear corneal sutureless phacoemulsification and to analyze the factors affecting them. DESIGN: Cohort study. METHODS: Patients who underwent phacoemulsification cataract surgery from October 2016 to June 2018 in a tertiary center were enrolled. Margin reflex distance 1 (MRD1), MRD2, and levator function were measured and facial photography was taken before, 1 month, and at least 6 months after the surgery. Clinical ptosis was defined as any postoperative drop of MRD1 and clinically significant ptosis as MRD1 drop of ≥2 mm. Photo-based ptosis was assessed by a masked oculofacial plastic surgeon at the end of the study. RESULTS: A total of 234 patients (313 eyelids) were included. The majority of surgeries were performed by senior residents (65.5%, 205/313) and under topical anesthesia (78.0%, 244/313). Persistent clinical, clinically significant, and photo-based ptosis were 25.4% (71/279), 3.2% (9/279), and 3.3% (9/276). Eyelids with persistent postoperative ptosis showed a significantly (P = .03) lower preoperative levator function (13.9 vs 15.8 mm). No other factor was significantly different between the eyelids with and without postoperative ptosis. CONCLUSION: Persistent clinically significant ptosis was observed in more than 3% of patients undergoing clear corneal sutureless phacoemulsification cataract surgery. It should be counseled preoperatively. Lower preoperative levator function was significantly associated with a higher frequency of postoperative ptosis. Duration of surgery, level of surgeons, and other variables did not have any significant effect on the frequency of postoperative ptosis.

Complications in the first 10 phacoemulsification cataract surgeries with and without prior simulator training / Complicações nas 10 primeiras cirurgias de catarata por facoemulsificação com e sem treinamento prévio em simulador

ABSTRACT Purpose: To evaluate whether training medical residents with the Eyesi® cataract surgery simulator reduces the occurrence of intraoperative complications. Methods: This was a retrospective study in which the first 10 phacoemulsification surgeries performed by two groups of second-year ophthalmology residents were evaluated, during 2014 and 2015. The first Group consisted of seven residents from 2014 who had not had previous training with the simulator. The second Group was formed of seven residents in 2015, who had completed the C-level (intermediate) training with the simulator before beginning surgery on patients. We then compared these two groups regarding the frequency of occurrence of the four main intraoperative surgical complications: posterior capsule rupture, aphakia, and nucleus fragment dislocation into the vitreous, and extracapsular conversion. Results: A total of 140 surgeries were performed, 70 by Group 1 and 70 by Group 2. The total number of complications was 19 (27.14%) in Group 1 and nine (12.86%) in Group 2, and this reduction was significant (p=0.031). Fourteen (20%) surgeries in Group 1 and seven (10%) in Group 2 had complications. The complications were 13 posterior capsule ruptures (18.57%) in Group 1 and seven (10%) in Group 2; three eyes had nucleus fragment dislocations (4.29%) in Group 1, but only one (1.43%) in Group 2; two extracapsular conversions (2.86%) occurred in Group 1 and one (1.43%) in Group 2; and there was one aphakia (1.43%) in Group 1. Conclusions: The training with the Eyesi® cataract surgery simulator significantly reduced the total number of intraoperative complications in the first 10 phacoemulsification cataract surgeries performed by ophthalmology residents.

Perceived difficulties and complications in learners of phacoemulsification: A principal component analysis model.

PURPOSE: To evaluate the difficulty perceived of each step of phacoemulsification and analyze the factors affecting them. METHODS: Overall, 12 trainee residents were allotted 10 cases of phacoemulsification of eyes with senile cataract, under a single observer, and the steps of each surgery were rated from very easy to very difficult with a questionnaire. The completion rates of steps and complications of each surgery were noted. Principal component analysis of the responses to the difficulty level questionnaire was conducted to obtain factors resulting in the perceived difficulty. RESULTS: The lowest difficulty scores were for initial step of incision creation (1.63 ± 0.84), followed by intraocular lens insertion (2.51 ± 0.8). The most difficult step was divide/chop of the nucleus (3.74 ± 0.97) followed by phacoemulsification (3.32 ± 0.82). Highest completion rates were seen for the initial steps of the surgery and the lowest for divide/chop. We identified two major patterns of difficulty among the trainees - one for steps involving high amount of binocularity and the other, for steps involving high precision of hand control. The rate of complication of our study was within acceptable range. CONCLUSION: Although trainees have practiced phacoemulsification steps on simulation, real-life situation may bring in unprecedented level of difficulty and challenges, which may be documented and used for targeted improvement of surgical skills. Stereopsis and hand control training should form a major part of training modules of cataract surgery both on simulation and real-life scenarios.

A Comparison of Deep Sclerectomy Trainer Versus Trainee Outcomes.

PURPOSE: The aim of this study was to compare the results of deep sclerectomy (DS) and combined deep sclerectomy with phacoemulsification (phaco-DS) performed by clinical fellows with those by an experienced glaucoma surgeon and DS trainer. PATIENTS AND METHODS: This is a retrospective nonrandomized study of 266 eyes of 226 consecutive patients who had DS or phaco-DS between March 2014 and December 2016 which were included from a database of all glaucoma surgery performed in our department. A minimum of 9 months follow-up was required. The cases were recorded as to whether a fellow or consultant performed the entire procedure. Overall, 114 surgeries were performed by the consultant and 164 surgeries were performed by the fellow, in which 91 cases received no assistance from the consultant. Intraocular pressure (IOP) success criteria were: (A) IOP<22 mm Hg and/or 20% decrease from baseline off any glaucoma medications and (B) IOP<16 mm Hg and/or 30% drop from baseline off any glaucoma medications. RESULTS: No statistically significant difference was noted by any criteria (P<0.05) between the 2 groups. The Kaplan-Meir IOP success rates at 2 years with criteria B (IOP<16 mm Hg without medications) were 64% for consultant, 76% for independent surgeries done by a fellow and 72% for surgeries with assistance from the consultant trainer (P=0.15). There were no significant differences between measured IOPs at any time after surgery. Intraoperative perforation of trabeculo-Descemet membrane was noted in 4 cases (3.5%) done by the consultant and 12 cases (7.3%) performed by fellows (Fisher exact P=0.19). CONCLUSIONS: IOP outcomes of DS and phaco-DS were not adversely affected if fellows performed surgery, whether under supervision or independently.

Everything is ok on YouTube! Quality assessment of YouTube videos on the topic of phacoemulsification in eyes with small pupil.

OBJECTIVE: Usage of YouTube as an educational tool is gaining attention in academic research. To date, there has been no study on the content and quality of eye surgery videos on YouTube. The aim of this study was to analyze YouTube videos on phacoemulsification in eyes with small pupil. METHODS: We searched for the phrases "small pupil cataract surgery," "small pupil phacoemulsification," "small pupil cataract surgery complications," and "small pupil phacoemulsification complications" in January 2015. Each resulting video was evaluated by all authors, and Krippendorff's alpha was calculated to measure agreement. Videos were classified according to pupil size (small/very small) in the beginning of the surgery, and whether pupillary diameter was large enough to continue surgery safely after pupillary dilation by the surgeon in the video (safe/not safe). Methods of dilatation were also analyzed. Any stated ocular comorbidity or surgical complications were noted. RESULTS: A total of 96 videos were reviewed. No mechanical intervention for pupillary dilatation was performed in 46 videos. Fifty-eight operated eyes had no stated ocular comorbidity. Ninety-five operations ended successfully without major complication. There was fair agreement between the evaluators regarding pupil sizes (Kα = 0.670) but poor agreement regarding safety (Kα = 0.337). CONCLUSIONS: YouTube videos on small pupil phacoemulsification have low complication rates when compared to the literature, although no reliable mechanical dilatation methods are used in almost half of these videos. Until YouTube's place in e-learning becomes clearer, we suggest that viewers be cautious regarding small pupil phacoemulsification videos on YouTube.

Comparison of two popular nuclear disassembly techniques for cataract surgeons in training: divide and conquer versus stop and chop.

PURPOSE: To compare two common phacoemulsification techniques in the learning curve phase, and their effect on ultrasound energy dissipation. METHODS: One hundred and ten consecutive patients scheduled for cataract surgery with the same surgeon in training were prospectively enrolled. Study was divided in two parts. In the first one, 60 patients were stratified for cataract grade [nuclear opalescence (NO) grade 2-4] and divided in two groups receiving surgery with the divide-and-conquer technique (Group-1) and with the stop-and-chop technique (Group-2). In the second part, 50 patients were stratified according to cataract grade (NO2-6), and the surgeon had to choose one of the two techniques according to personal preference. The primary outcome was the cumulative dissipated energy (CDE). RESULTS: Significant differences of CDE were observed between the NO3 and NO4 cataracts in Group-1. In Group-2, this difference was not significant, suggesting that with more advanced cataracts, the stop-and-chop technique allows less ultrasound use. In the second part of the study, the stop and chop was most frequently used for more advanced cataracts. When considering harder cataracts (NO5-NO6), patients receiving surgery with the divide-and-conquer technique had higher CDE values compared to stop and chop. CONCLUSIONS: Both divide-and-conquer and stop-and-chop techniques are efficient in the learning curve. Stop and chop dissipates less energy in harder nuclei. Once surgeons reach sufficient experience with both techniques, they should switch to a stop-and-chop technique, allowing lower levels of ultrasound energy.

Computer analysis of individual cataract surgery segments in the operating room.

PURPOSE: Objective feedback is important for the continuous development of surgical skills. Motion tracking, which has previously been validated across an entire cataract procedure, can be a useful adjunct. We aimed to measure quantitative differences between junior and senior surgeons' performance in three distinct segments. We further explored whether automated analysis of trainee surgical videos through PhacoTracking could be aligned with metrics from the EyeSi virtual reality simulator, allowing focused improvement of these areas in a controlled environment. METHODS: Prospective cohort analysis, comparing junior vs. senior surgeons' real-life performance in distinct segments of cataract surgery: continuous curvilinear capsulorhexis (CCC), phacoemulsification, and irrigation and aspiration (I&A). EyeSi metrics that could be aligned with motion tracking parameters were identified. Motion tracking parameters (instrument path length, number of movements and total time) were measured. t-test used between the two cohorts for each component to check for any significance (p < 0.05). RESULTS: A total of 120 segments from videos of 20 junior and 20 senior surgeons were analysed. Significant differences between junior and senior surgeons were found during CCC (path length p = 0.0004; number of movements p < 0.0001; time taken p < 0.0001), phacoemulsification (path length p < 0.0001; number of movements p < 0.0001; time taken p < 0.0001), and irrigation and aspiration (path length p = 0.006; number of movements p = 0.013; time taken p = 0.036). CONCLUSION: Individual segments of cataract surgery analysed using motion tracking appear to discriminate between junior and senior surgeons. Alignment of motion tracking and EyeSi parameters could enable independent, task specific, objective and quantitative feedback for each segment of surgery thus mirroring the widely utilised modular training.

Outcomes in resident-performed cataract surgeries with iris challenges: Results from the Perioperative Care for Intraocular Lens study.

PURPOSE: To assess the outcomes of resident-performed cataract surgeries with iris challenges and to compare these outcomes with similar surgeries performed by attending surgeons. SETTING: Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, Massachusetts, USA. DESIGN: Retrospective chart review. METHODS: All cases of cataract extraction by phacoemulsification with intraocular lens implantation, performed by comprehensive ophthalmologists between January 1 and December 31, 2014, were reviewed. Cases with preoperative or intraoperative miosis, iris prolapse, and intraoperative floppy iris syndrome, were included for analysis. Visual outcomes and the rate of perioperative adverse events were compared between resident and attending surgeon cases. Factors predicting adverse events were also assessed. RESULTS: In total, 1931 eye cases of 1434 patients were reviewed, and 65 resident cases and 168 attending surgeon cases were included. The mean logarithm of the minimum angle of resolution corrected distance visual acuity was better in the resident group 1 month after surgery (0.051 ± 0.10 [SD] versus 0.132 ± 0.30, P = .03); however, the difference was eliminated when controlling for macular disease. The mean operative time was 43.8 ± 26.5 minutes and 30.9 ± 12.6 minutes for cases performed by resident surgeons and attending surgeons, respectively (P  .0001). Residents utilized supplemental pharmacologic dilation or retraction more frequently than attending surgeons (98% versus 87% of cases, P = .008). The overall rate of adverse events was no different between residents and attending surgeons (P = 0.16). Dense nuclear sclerosis predicted adverse events in cataract cases with iris challenges (adjusted odds ratio, 1.86; 95% confidence interval, 1.17-2.94; P = .001). CONCLUSION: Although requiring longer operative times and more surgical manipulation, residents who performed cataract surgeries with iris challenges achieved outcomes comparable to those performed by attending surgeons, and residents should be given the opportunity to operate on these eyes.

Improved utilization of operating room time for trainee cataract surgery in a public hospital setting.

PURPOSE: To examine the effect of group goal and group performance theories on operating room efficiency in resident-performed cataract surgery. SETTING: Zuckerberg San Francisco General Hospital and Trauma Center, Department of Ophthalmology, University of California, San Francisco, California, USA. DESIGN: Prospective case series. METHODS: This study assessed 4 specific segments of operating room utilization identified as room-to-incision time, incision-to-close time, close-to-exit time, and room turnover time. The time segments were measured for resident-performed cataract cases before the proposed intervention. Then, group goals were set for ideal times of each utilization segment. Behaviors of the surgery, anesthesia, nursing, pharmacy, and housekeeping teams that would improve group performance were identified. Utilization segments were measured again after the intervention. RESULTS: The time segments were measured for 134 resident-performed cataract cases before the proposed intervention and again after the intervention for 136 resident-performed cataract cases. Before the intervention, the mean overall case time was 55 minutes, allowing for 10 cases in a 10-hour day. After the intervention, the mean overall case time was 46 minutes, allowing for 13 cases in a 10-hour day. The decrease in postintervention times for overall case time, room-to-incision time, and close-to-exit time were statistically significant. CONCLUSIONS: Operating room utilization for resident-performed cataract surgery was enhanced by setting group goals. A multidisciplinary effort to enhance group performance through behavior modification can be implemented immediately and improve efficiency without compromising patient safety or resident teaching.

Supervised resident manual small-incision cataract surgery outcomes at large urban United States residency training program.

PURPOSE: To examine the outcomes of resident-performed manual small-incision cataract surgery (SICS) in an urban academic setting. SETTING: Parkland Memorial Hospital, Dallas, Texas, USA. DESIGN: Retrospective case series. METHODS: Manual SICS was used only in selected cases for which phacoemulsification was expected to be difficult, namely for mature or brunescent cataracts, traumatic cataracts, and pseudoexfoliation syndrome or other causes of zonular weakness. All manual SICS cases performed by resident physicians as the primary surgeon over a 5-year period were reviewed. Postoperative visual acuity, intraoperative complications, and early postoperative complications were the main outcomes measured. RESULTS: For the 52 cases identified, the mean preoperative visual acuity was 2.165 logarithm of the minimum angle of resolution (logMAR) ± 0.141 (SD) (95% confidence interval) (slightly better than had motion acuity), improving to 0.278 ± 0.131 logMAR (Snellen 20/38) corrected visual acuity postoperatively. Of the 52 cases, the most frequent intraoperative complications were iris prolapse (5 cases [9.6%]) and zonular dialysis (4 cases [7.7%]), with vitreous loss occurring in 1 case (1.9%). The most frequent postoperative complications were cystoid macular edema (3 cases [5.8%]), retained ophthalmic viscosurgical device (2 cases [3.8%]), intraocular lens displacement (2 cases [3.8%]), and microhyphema (2 cases [3.8%]). CONCLUSIONS: Although the more advanced wound construction in manual SICS might be challenging to surgeons unfamiliar with the technique, it was a safe and efficacious technique in the hands of learning residents. With several advantages over phacoemulsification, such as cost and ability to remove very dense nuclei, manual SICS will play a valuable role in modern cataract surgery.

A review of teaching methods and outcomes of resident phacoemulsification.

Cataract surgery with phacoemulsification is a challenging procedure for surgeons in training to learn to perform safely, efficiently, and effectively. We review the auxiliary learning tools outside the operating room that residency programs have incorporated into their curriculum to improve surgical skills, including wet laboratory and surgical simulators. We then discuss different methods of teaching cataract surgery in the operating room. Our goal is to define a learning curve for cataract surgery. We demonstrate that complication rates decline significantly after a resident performs an average of 70 cases. We summarize the reported incidence and risk factors for complications in resident-performed cataract surgery to help identify cases that require a higher level of skill to improve visual outcomes. We suggest that future studies include details on preoperative comorbidities, risk stratification, resident skill level, and frequency of takeover by attending.

Advanced cataract learning experience in United States ophthalmology residency programs.

This study examined resident exposure to and competency in new techniques for cataract removal and intraocular lens (IOL) implantation. A questionnaire was sent to 116 United States ophthalmology program directors and completed by 71. In response to the questionnaire, program directors reported that 95.3% of their graduating seniors were competent to select and implant toric IOLs and 52.3% were competent to implant capsular tension rings (CTRs). Divide and conquer (56.6%) and stop and chop (25.4%) dominated phacoemulsification teaching. Femtosecond laser-assisted cataract surgery was performed by residents in 44.1% of programs. In 25.4%, residents observed but did not perform the procedure; in 35.6%, they received didactic-only training; and in 22.0%, they received no exposure. Most programs (73.2%) had virtual-reality simulators for cataract surgery, but wet-lab practice (91.1%), didactic training (82.1%), and watching videos (82.1%) were the primary curricular tools used to teach advanced technologies.

[Cost of teaching cataract surgery in a public hospital]. / Évaluation du coût de l'enseignement de la chirurgie de la cataracte dans un établissement public de santé.

INTRODUCTION: The gold standard of cataract surgery, phacoemulsification is the most commonly performed surgical procedure in France. Surgical instruction often takes place in the operating room where residents and fellows perform real surgery, supervised by an experienced surgeon. The goals of this study were double: evaluate surgical times according to the person performing the surgery, in order to quantitate the cost incurred by teaching and compare complication rate between surgeons. METHODS: A retrospective single center study was performed at Simone-Veil Hospital, Eaubonne-Montmorency, France. Over a period of 13 consecutive weeks from January to March 2016, all patients who underwent phacoemulsification for cataract extraction were included. Patients were separated into three groups, according to the primary surgeon: group S for Senior was composed of two experienced surgeons who typically performed over 500 procedures per year; group A for assistant was composed of three residents who performed less than 500 procedures per year; 2 inexperienced interns constituted group I. Surgery duration was recorded by the OR nurse in minutes between the first incision and removal of the lid speculum. The cost of operating room time was estimated at seven euros per minute. The occurrence of complications was determined from the operative report. RESULTS: 408 cataract surgeries were performed during the study period, divided into 156 eyes in group S, 142 in group A and 110 surgeries in group I. The mean age at surgery was 74.1±9 years (39-95), comparable in the 3 groups. The operative time was significantly shorter in group S (11.7min) than in A (18.7min; P<0.001) and in I (18.8min; P<0.001). The complication rate was higher in group I than in group S (P=0.03). The average additional cost related to the lengthening of the teaching procedure was 49 euros for Group A and 49.7 euros for Group I. DISCUSSION: The hospital reimbursement for cataract surgery is higher in the public sector than in the private sector; it can absorb the cost of university training. CONCLUSION: Teaching cataract surgery entails an additional financial cost for the hospital. It is also responsible for a higher human cost due to a greater number of operative complications with interns.

[Evaluation of surgical simulation sessions of the French society of ophthalmology. A new surgical instruction method]. / Évaluation des sessions sur simulateurs chirurgicaux de la Société française d'ophtalmologie. Une nouvelle pédagogie chirurgicale.

INTRODUCTION: Since 2013, at the French society of ophthalmology (FSO) meetings, two simulators for intraocular surgeries have been available. The goal of this study was to assess the satisfaction of the participants in these organized training sessions. MATERIALS AND METHODS: A questionnaire was mailed to participants in the FSO sessions as well as those carried out during the annual congress. This questionnaire collected data on the participants and the practical modalities of the sessions, and assessed participants' feelings and satisfaction with these sessions. RESULTS: The participants in the SFO sessions were young members of the SFO (31.8±12.3 years). 53.8 % were in training, looking to improve a problematic surgical step (capsulorhexis in 51.5 %). They spent nearly 5hours on simulators (4.8hours) and were alone on a simulator 50 % of the time. The sessions held during the annual congress were used by older physicians (41.9±26.4 years) already in practice (66.6 %). The goal of such training was curiosity in a third of the cases (to try the simulators). The majority spent less than an hour on the devices and were at least two participants per machine. Despite these differences, participants cited a role for their surgical learning curve and recommended such training to their colleagues. CONCLUSIONS: The participants' enthusiasm for this new training technique is highlighted by the results of this study.
