Mental Distress Among Cancer Sufferers In the course of COVID-19 Widespread on earth: A planned out Evaluate.
This study aimed to describe the response of heart rate (HR) and the subjective rating of perceived exertion (RPE) during a simulated DanceSport competition. The mean and maximum HR of 18 dancers of the highest level were evaluated during a simulated DanceSport competition consisting of 5 Latin dances. RPE values were recorded immediately after each dance. The dances were ranked as follows according to the mean HR (samba [165.3 ± 16.3 bpm] less then rumba bolero [176.9 ± 9.9 bpm] less then cha-cha-chá [179.1 ± 11.4 bpm] = paso doble [182.5 ± 12.5 bpm] = jive [184.3 ± 11.4 bpm]); maximum HR (samba [185.6 ± 8.9 bpm] = rumba bolero [187.0 ± 9.1 bpm] less then cha-cha-chá [190.1 ± 8.0 bpm] = paso doble [191.4 ± 9.0 bpm] less then jive [194.2 ± 8.1 bpm]); and RPE (rumba bolero [5.22 ± 1.40] less then samba [6.42 ± 2.06] = cha-cha-chá [6.78 ± 1.31] = paso doble [7.39 ± 1.04] less then jive [8.33 ± 0.91]). The only significant correlation between RPE and HR values was observed for the maximum HR during the first dance of the competition (samba) (r = 0.485). A simulated DanceSport competition causes high physiological stress being influenced by the type of dance.
Patellofemoral chondropathy (PFC) is one of the most important causes of patellofemoral pain syndrome. RG7388 PFC may occur as a result of anatomic reasons such as patellar malalignment and/or increased patellofemoral joint stresses. Most research on this subject has involved sports injuries and anatomic variations. The literature is scarce on PFC related to the dance.

Fourteen dancers (14 knees, all male) were found to have PFC based on MRI evaluations and clinical examinations between January 2010 and December 2019 (3 dancers were excluded due to prior surgeries of the knee). Age, sex, side of injury, range of motion, Q angle, types of dances, body mass index, and patellar specifics (alta, baja, Wiberg) were recorded for 11 dancers included in the study. We observed PFC at the femoral contact areas (FCA) and patellar contact areas (PCA) of Goodfellow description.

Chondral lesions were observed at Gooodfellow areas FCA-3 in 2 dancers, FCA-4 in 5 dancers, PCA-2 in 10 dancers, PCA-3 in 10 dancers, and PCA-4 in 9 dancers.

Dance styles that include frequent deep flexions and strolling on a flexed knee joint may be risk factors for chondral lesions in the contact area of the femur in male dancers.

Hand-held dynamometry is considered an efficient, effective, and portable means of objectively measuring lower extremity strength; however, it has yet to be studied specific to dance-relevant muscle performance. Also, dynamometry is often criticized for variability in results based on tester strength and sex. Use of an external stabilizing device has been suggested to minimize differences in outcomes between male and female testers by reducing variability associated with tester strength limitations. Therefore, this study used a barre-mounted, portable dynamometer stabilizing device to improve consistency of results among different testers for assessing hip and lower extremity muscle performance in dance-relevant positions.

To assess the intra and inter-rater reliability of a barre-mounted dynamometer stabilizing device in measuring muscle performance in common dance maneuvers.

Two testers assessed muscle performance of three common dance maneuvers--développé en avant, à la secondé, and arabesque--on 11 testing device into wider scale screenings could assist in developing normative data for a population that is lacking.

Altered ground reaction force (GRF) and joint torsional stiffness are associated with various lower extremity injuries, but these have yet to be examined in dancers with flexor hallucis longus (FHL) tendinopathy. Additionally, a simple, field-friendly kinematic correlate to ground contact kinetics would be useful for clinical application. The purpose of this study was to compare lower extremity biomechanics during takeoff of a dance leap (saut de chat) in dancers with and without FHL tendinopathy, and to examine lower limb posture at initial contact as a clinical correlate of injury-related kinetic factors.

Motion capture and inverse dynamics were used to analyze saut de chat takeoff performed by 11 uninjured dancers and 8 dancers with FHL tendinopathy. GRF parameters, joint torsional stiffness of the metatarsophalangeal, ankle, and knee joints, and lower extremity posture at initial contact were compared between groups using Welch's t-tests.

Dancers with FHL tendinopathy maintained similar jump height as the uninjured dancers, but exhibited lower peak vertical GRF, longer time to peak force, and less joint torsional stiffness at the metatarsophalangeal, ankle, and knee joints during loading response of the takeoff step. Lower extremity contact angle was smaller and the horizontal distance between center-of-mass and center-of-pressure was greater in dancers with FHL tendinopathy. These two measures of lower limb posture at initial contact were significantly correlated with kinetic factors occurring later in ground contact (R2=0.29-0.51).

Dancers with FHL tendinopathy demonstrated altered lower extremity kinetics during takeoff of a leap compared to uninjured dancers, which may contribute to, or be a compensation response to, injury.

This study aimed to assess the effectiveness of the "modified graded motor imagery" (mGMI) protocol as a rehabilitative treatment of musician's focal dystonia (MFD).

Six musicians with MFD (age 43.83±17.24 yrs) performed the home-based mGMI protocol (laterality training, imagined hand movements and visual mirror feedback) once a day for 4 weeks. The mMGI protocol was designed to sequentially activate cortical motor networks and improve cortical organization. Subjects were evaluated before and after treatment with the dystonia evaluation scale (DES), arm dystonia disability scale (ADDS), Tubiana-Chamagne scale (TCS), and performing scale (PS).

All participants were compliant with the mGMI treatment protocol without any adverse events. A significant improvement was measured in ADDS (p=0.047) and TCS scores (p=0.014) but not in DES (p=0.157). The severity of MFD decreased from moderate to mild in four patients. After mGMI treatment, all musicians were able to play easy pieces (TCS median 3.5, IR 3.5-4).

The findings from this pilot study suggest that home-based mGMI treatment is a feasible and promising rehabilitative approach for patients with mild to moderate MFD.
