“…The work of Nicolay and Walker (2005) was one of the reported studies most similar to the present investigation. The static endurance during 30 s was evaluated for the dominant and non-dominant limbs of healthy non-sedentary young individuals (although no reports of physical activities were provided).…”

Abstract-This study aimed to identify useful electronic grip dynamometry parameters to track differences between trained (TR) and untrained (UT) participants, and between dominant (DO) and non-dominant (ND) limbs as a consequence of upper limbs muscle fatigue following 10 RM tests of the brachial biceps. This experimental study with transversal design involved 18 young adult males, of whom 9 were untrained and 9 were experienced in resistance training.Isometric grip force was evaluated (30 seconds long) previous and after 10RM tests by means of a G200 Model grip dynamometer with precision load cell (Biometrics®). Significant differences between initial and final measurements were found only for trained participants: Peak force for TR-DO (67.1 vs 55.5 kgf, p = .0277); Raw average for TR-DO (46.96 vs 42.22 kgf, p = .0464), and for TR-ND (40.34 vs 36.13 kgf, p = .0277). Electronic grip dynamometry efficiently identified upper limbs fatigue in trained participants, being raw average measurements the best parameter.Keywords: muscle strength dynamometer, muscle fatigue, hand strength, resistance training.Resumo-"Rastreamento de fadiga de membros superiores por meio da dinamometria eletrônica." Objetivou-se identificar parâmetros da dinamometria eletrônica de preensão palmar úteis para monitorar diferenças entre indivíduos treinados (TR) e não treinados (UT) e entre membros dominantes (DO) e não dominantes (ND) após indução de fadiga pelo teste de 10RM para bíceps braquial. Tratou-se de estudo experimental, transversal, envolvendo 18 homens adultos jovens, 9 não treinados e 9 experientes em treinamento resistido. Avaliou-se a força isométrica de preensão palmar (por 30 segundos) antes e após o teste de 10 RM por dinamômetro de preensão com célula de carga de precisão modelo G200 (Biometrics®). Houve diferença significativa entre valores iniciais e finais somente para treinados: Pico de força para TR-DO (67,1 vs 55,5 kgf, p = 0,0277); média bruta para TR-DO (46,96 vs 42,22 kgf, p = 0,0464) e para TR-ND (40,34 vs 36,13 kgf, p = 0,0277). A dinamometria eletrônica mostrou-se eficaz em identificar a fadiga de membros superiores nos participantes treinados, sendo a média bruta o melhor parâmetro.Palavras-chave: dinamômetro de força muscular, fadiga muscular, força da mão, treinamento de resistência.Resumen-"Seguimiento de fatiga de miembros superiores mediante dinamometría electrónica."

ÖzetAmaç: Pelvik organ prolapsusu(POP) doğum yapmış kadınların %50'sinde gözlenen, sık bir patolojidir. Pelvik organ prolapsusunun önde gelen sebebi pelvic taban kaslarının zayıflığıdır. El kavrama gücü, total kas gücü ile ilişkili-dir ve kişinin genel kas gücünü değerlendirmek için kullanılabilir. El kavrama gücünün ölçümü Jamar dinamometre adında taşınabilir bir dinamometre ile yapılır. POP olan hastalarda genel kas gücünün azalmış olabileceği hipotezini kurduk. Gereç ve Yöntem: Namık Kemal Üniversitesi Tıp Fakültesi Jinekoloji kliniğine başvuran hastalardan, POP tanısı alan 20 hasta ve kontrol grubuna alınan 21 hasta çalışmaya alındı. POP-Q klasifikasyonu prolapsusun şiddetini değerlendirmek için kullanıldı. Jamar hidrolik el dinamometresi ile el kavrama gücü ölçüldü. Bulgular: Prolapsus grubunda medyan POP skoru 3 (1-4) idi. İki grupta ortalama Jamar Skorları sağ el için, sol el için ve dominant el için benzerdi (p=0.774, p=0.575 and p=0.707). Prolapsus grubunda ortalama vücut yağ oranı %33.9 ± 5.7 iken kontrol grubunda %38.9 ± 7.4 idi(p=0.021). Tartış-ma: Çalışmamızda POP grubu ile sağlıklı kontroller arasında genel vücut kas gücü açısından fark bulmadık. Sonuçlarımız vücudun genel kas gücünü göste-ren Jamar Skorlarının pelvik organ kas gücü ile ilişkili olmadığını göstermiştir. Anahtar KelimelerPelvik Organ Prolapsusu; El Kavrama Gücü; Kas Gücü Abstract Aim: Pelvic organ prolapse(POP) is a common condition that is observed in 50% of parous women. Weakness of pelvic floor muscles is an important factor that leads to POP. The hand grip strength is related to total muscle strength and it could be used to evaluate one's general muscle strength. The Jamar hand dynamometer is a portable dynamometer that uses a strain gauge to measure hand grip strength. We hypothesized that general muscle strength would be impaired in patients with POP. Material and Method: Twenty patients with pelvic organ prolapse and twenty-one controls were recruited from the gynecology clinic of Namik Kemal University School of Medicine. The POP-Q classification was used to quantify the clinical severity of the prolapse. Hand grip strength was measured using a JAMAR hydraulic hand dynamometer. Results: The median pelvic organ prolapse score was 3 (1-4) in prolapse group. The mean Jamar scores of both groups were similar for the right hand, the left hand and the dominant hand (p=0.774, p=0.575 and p=0.707, respectively).The mean body fat percentage was 33.9 ± 5.7 % in prolapses group and it was 38.9 ± 7.4% in control group (p=0.021). Discussion: We found no difference in terms of general muscle strength between POP group and healthy controls. Our results showed that Jamar scores, which represented general muscle strength of body, did not related to pelvic organ muscle strength.

“…[29] Research comparing the functional and grip strength results of RHP and RHR in the treatment of Mason Type-III radial head fractures is limited. In our study, the mean functional score and grip strength results were superior in patients treated with RHP, but this difference did not reach significance, which may be attributable to our small number of patients.…”

BACKGROUND:The radial head is essential for the rotational stability of the forearm and resistance to valgus stress. Radial head fractures are the most common elbow fracture in adults. Various treatment options are available, depending on the fracture severity. However, the treatment of Type-III fractures is controversial. The aim of this study was to evaluate functional results in patients with irreparable Mason Type-III radial head fractures treated with radial head resection or prosthesis.
