“…For the statistical analysis we chose the best value of two scores. Hamilton et al did not find any difference between using the mean values or the best value to determine the grip strength score [28]. The interindividual differences of muscular strength are wide even in healthy people and differ depending on sex, age, height and weight [3,34,42].…”

Cervical radiculopathy: Pain, muscle weakness and sensory loss in patients with cervical radiculopathy treated with surgery, physiotherapy or cervical collar A prospective, controlled study

et al. 1997

This prospective, randomised study compares the efficacy of surgery, physiotherapy and cervical collar with respect to pain, motor weakness and sensory loss in 81 patients with long-lasting cervical radiculopathy corresponding to a nerve root that was significantly compressed by spondylotic encroachment, with or without an additional bulging disk, as verified by MRI or CT-myelography. Pain intensity was registered on a visual analogue scale (VAS), muscle strength was measured by a hand-held dynamometer, Vigorometer and pinchometer. Sensory loss and paraesthesia were recorded. The measurements were performed before treatment (control 1), 4 months after the start of treatment (control 2) and after a further 12 months (control 3). A healthy control group was used for comparison and to test the reliability of the muscle-strength measurements. The study found that before start of treatment the groups were uniform with respect to pain, motor weakness and sensory loss. At control 2 the surgery group reported less pain, less sensory loss and had better muscle strength, measured as the ratio of the affected side to the non-affected side, compared to the two conservative treatment groups. After a further year (control 3), there were no differences in pain intensity, sensory loss or paraesthesia between the groups. An improvement in muscle strengths, measured as the ratio of the affected to the non-affected side, was seen in the surgery group compared to the physiotherapy group in wrist extension, elbow extension, shoulder abduction and internal rotation, but there were no differences in the ratios between the collar group and the other treatment groups. With respect to absolute muscle strength of the affected sides, there were no differences at control 1. At control 2, the surgery group performed somewhat better than the two other groups but at control 3 there were no differences between the groups. We conclude that pain intensity, muscle weakness and sensory loss can be expected to improve within a few months after surgery, while slow improvement with conservative treatments and recurrent symptoms in the surgery group make the 1-year results about equal.

Abstract-Hyperthyroidism is a pathologic condition in which the body is exposed to excessive amounts of circulating thyroid hormones. Skeletal muscle is one of the major target organs of thyroid hormones. We evaluated hand grip strength and function in patients with overt hyperthyroidism. Fifty-one patients newly diagnosed with hyperthyroidism and 44 healthy controls participated in this study. Age, height, weight, and dominant hand of all participants were recorded. The diagnosis of hyperthyroidism was confirmed by clinical examination and laboratory tests. Hand grip strength was tested at the dominant hand with a Jamar hand dynamometer. The grooved pegboard test (PGT) was used to evaluate hand dexterity. The Duruöz Hand Index (DHI) was used to assess hand function. No significant differences were found in terms of clinical and demographic findings between the patients with hyperthyroidism and healthy controls (p > 0.05). Significant differences were found between the patients with hyperthyroidism and healthy controls regarding PGT and DHI scores (p < 0.05). Hyperthyroidism seemed to affect hand dexterity and function more than hand grip strength and seemed to be associated with reduced physical function more than muscle strength. This may also indicate that patients with hyperthyroidism should be evaluated by multidisciplinary modalities.

Medida da força de preensão manual- validade e confiabilidade do dinamômetro saehan

Nada a declarar RESUMO: Existe uma grande variedade de instrumentos utilizados para a avaliação da força de preensão manual. Porém, não existem estudos demonstrando a validade e a confiabilidade da maioria destes instrumentos. O objetivo deste estudo foi avaliar a validade concorrente e a confiabilidade intraexaminador do dinamômetro Saehan hidráulico comparado-o com o dinamômetro Jamar hidráulico. Cem indivíduos sadios (50 homens e 50 mulheres), entre 20 e 50 anos de idade, sem alterações cognitivas, deficiências físicas, disfunções neuromusculares e ortopédicas e história de lesões nos membros superiores, foram testados com os dinamômetros Jamar e Saehan. A validade concorrente entre o dinamômetro Jamar e o dinamômetro Saehan foi excelente para os testes de força de preensão realizados com as mãos direita (r=0,976) e esquerda (r=0,986). A confiabilidade intra-examinador foi excelente tanto para o dinamômetro Jamar (r=0,985 mãos direita e esquerda) quanto para o dinamômetro Saehan (r=0,981 mão direita e r=0,985 mão esquerda). O dinamômetro Saehan é válido, confiável e comparável com o dinamômetro Jamar. Portanto, dados coletados com o dinamômetro Jamar são equivalentes aos dados coletados com o dinamômetro Saehan. Consequentemente, valores de força obtidos por testes com dinamômetro Saehan podem ser comparados com valores de referência de força de preensão que foram obtidos com o dinamômetro Jamar. DEScRitORES: dinamômetro; força de preensão manual; validade; confiabilidade.ABStRAct: There is a great variety of instruments available for evaluating hand grip strength. There is, however, a lack of studies showing the validity and reliability of most of these instruments. The purpose of this study was to examine the concurrent validity and test-retest reliability of the hydraulic Saehan dynamometer using the hydraulic Jamar dynamometer. One hundred healthy subjects (50 men and 50 women), between the ages of 20 and 50 years old, without cognitive impairment, physical disability, neuromuscular or orthopedic dysfunction, and history of upper extremity injuries were tested with the Jamar and Saehan dynamometers. The concurrent validity between the Jamar and the Saehan dynamometers was excellent for both the right hand (r=0.976) and the left hand (r=0.986). Test-retest reliability was excellent for both the Jamar (r=0.985 right and left hands) and the Saehan (r=0.981 right hand and r=0.985 left hand). The Saehan dynamometer is valid, reliable and comparable to the Jamar dynamometer. Therefore, the Jamar and Saehan dynamometers measure handgrip strength equivalently. As a result, strength values obtained with the Saehan dynamometer can be compared with reference values which were collected with the Jamar dynamometer.
