“…Against this background, we carried out a double-blinded, randomized trial that aimed to evaluate the efficacy of compression therapy in both an objective and subjective manner. Both MRI and perometry are well-established, reliable methods to measure the change in volume of soft tissue [ 14 , 15 , 16 , 18 , 20 ]. The measurement using MRI showed a significant reduction in volume during wearing of compression stockings for class I and class II.…”

Venous malformations are one of the most common vascular anomalies. Our study aimed to investigate the effect of medical compression stockings of class I and II on the volume of venous malformations. Patients with venous malformations on upper or lower extremities were enrolled. They wore flat-knitted medical compression stockings of class I and II in a randomized order for four weeks each. Magnetic resonance imaging (MRI) and perometry were performed with and without wearing compression stockings. The 12-Item Short Form Survey (SF-12) questionnaire was performed before and after wearing compression stockings for four weeks each. A total of 18 patients completed the evaluations. Both compression classes showed a significant reduction of the volume of the venous malformations in the lesion itself based on MRI in comparison with baseline (both p < 0.001). Measurements taken with perometry did not reveal a significant difference in comparison to baseline (p = 0.09 and p = 0.22). The results of the SF-12 questionnaire demonstrated no significant differences before and after wearing the compression stockings of class I or class II for four weeks or between the two classes of compression therapy. Our results indicate that wearing medical compression stockings of both class I and class II significantly reduces the volume of venous malformation, without compromising the quality of life, while the effect of class II compression stockings on volume reduction was significantly better than that of class I.

“…Perometry is a noninvasive measurement of the volume of the limbs via an optoelectronic system using infrared beams, which has been broadly applied on the evaluation of lymphedema [ 15 , 18 , 19 , 20 ]. The diameter of the limb can be calculated to an accuracy of ±2.54 mm by the number of light diodes that are attenuated by the limb.…”

“…In humans, objective limb volume measurements have been used in sports to assess muscle hypertrophy in response to training [9], as well as in medicine to assess the efficacy of treatments to lessen edema [10]. Human medical and research studies have compared the strengths and weaknesses of several methods for objective limb volume measurements including perometry, water displacement, circumferential models, as well as computed tomography and magnetic resonance imaging [11,12]. Advanced imaging and perometry devices have the greatest accuracy and reproducibility, but are only available in specialized facilities due to their expense and size.…”

Simple SummaryWhen horse athletes exercise, forces are applied to their legs during each step. Repetitive loads applied during training and competition contribute to stress of leg structures. Swelling (i.e., local fluid accumulation) in the legs is a sign of increased stress in these structures. Currently, horse riders and trainers make training decisions based on visual observations of horse leg swelling, which are potentially subjective and imprecise. The aim of this study was to develop a low-cost, noninvasive method to measure lower leg volume in horses, as well as to assess the ability to detect differences before and after exercise. The tablet-mounted scanner measured increased lower leg volume after jumping, compared to scans before exercise. This method may serve as an objective tool for horse riders and trainers to prevent injury by modulating horse training frequency and intensity in response to physiological signs of stress, like leg swelling. Scans may also be used to seek veterinary consultation and treatment, as well as to guide rehabilitation from injury. AbstractEquine athletes can incur musculoskeletal injuries due to repetitive loading during training and competition. Prior to signs of lameness, horse trainers and veterinarians may observe swelling in the distal limbs, where injuries most frequently occur. Early observations may guide modulation of training to manage physiological stress and mitigate risk of injury. However, these observations of changing limb volume can be subjective and imprecise. The aim of this study was to assess the accuracy and applicability of a tablet-mounted, 3D scanner to measure and record distal limb volumes of horses before and after exercise. Users recorded scans of a cylinder of known volume with errors up to 8%. Experienced users’ measures were biased (i.e., consistently overestimated). The scanner was able to detect statistically significant increases in volume for both fore and hind limbs after one jumping session (310–2058 cm3). Age and intensity of workload may play a role in magnitude of limb swelling, but had mixed conclusions between fore and hind limbs. More studies with additional horses must be performed to solidify these relationships. The evaluated 3D scanner is a low-cost, accessible tool that was able to detect changes in limb swelling as a result of exercise and mechanical stress. With continued research, this information may guide training programs to decrease injury and maximize performance of equine athletes in the future.

Background Breast cancer‐related lymphoedema (BCRL) presents a significant healthcare burden and adversely affects quality of life of breast cancer survivors. A prospective feasibility study was performed on lymphaticovenous anastomosis (LVA) for the treatment of BCRL. Methods Patients with BCRL underwent near‐infrared spectroscopy with indocyanine green lymphatic mapping to identify suitable lymphatic channels for LVA. End‐to‐end anastomoses to subdermal venules were performed and patients recommenced compression garment therapy (CGT) after surgery. Volumetric assessment of the affected limb was performed at regular intervals using infrared perometry to calculate the excess volume reduction. Results Over a 24‐month interval, 27 patients with BCRL underwent LVA. The mean duration of lymphoedema was 3·5 (range 0·5–18) years, and the mean number of LVAs performed was 3 (range 2–5). Twenty‐four of the 27 patients completed 12‐month follow‐up. Patients exhibited three patterns of volumetric response following LVA: sustained response (16 patients), transient response (5) or no response (6). Sustained responders showed an excess volume reduction of −33·2 per cent at 12 months, and this correlated positively with the number of LVAs performed (r = −0·56, P = 0·034). Overall, ten patients were able to downgrade CGT after surgery, and two patients were CGT‐free at 12 months. Conclusion LVA resulted in a sustained volume reduction in selected patients and may offset the burden of CGT. Further work is required to identify biomarkers that predict a favourable response to LVA surgery.
