PURPOSE To determine the reliability and measurement error of measurements of intrinsic muscle strength of a new hand-held dynamometer (the Rotterdam Intrinsic Hand Myometer [RIHM]). METHODS With the RIHM we obtained repeated measurements of the intrinsic muscle strength of the hand in 27 patients with peripheral nerve injury of the ulnar and/or median nerve in different stages of rehabilitat...

Carbonyls from gasoline-powered light-duty vehicles (LDVs) and heavy-duty diesel-powered vehicles (HDDVs) operated on chassis dynamometers were measured by use of an annular denuder-quartz filter-polyurethane foam sampler with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine derivatization and chromatography-mass spectrometry analyses. Two internal standards were utilized based on carbonyl recovery...

Tillage is the base operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. To measure the implement force requirements, are used dynamometers that are pull or three-point hitch types. In this research, an 82 kW research tractor equipped with an instrumentation system was used to determine the draft force inputs for four common tillag...

It has been shown that, in a bilateral force-matching task, subjects presenting weakness in one limb produce a lower force in the weakened limb even though they subjectively perceive that they are exerting the same force. The aim of this study was to verify whether subjects with hemiparesis produced asymmetrical forces during a bilateral submaximal grip task and whether this asymmetry is relate...

The engine control unit (ECU) is the primary component of current injection technique used in spark ignition (SI) engines. combustion system, which includes timing and timing, controlled by map recorded ECU. To maximize an engine's performance, ECU remapping can be used. Remapping currently not efficient because data typically employed a trial-and-error fashion. solve these issues, artificial n...

The type of muscle action is important when designing exercise interventions for older individuals and may result in different effects. In this study we performed a systematic review controlled trials comparing the effects concentric eccentric resistance training, on isokinetic dynamometers, lower extremity muscular functional performance adults (CDR42017075316). Six databases (Pubmed, CINAHL, ...

Original scientific paper The slip, the resistance to rolling and pulling force are interconnected. The influence of tyre wear on the tractor pulling force and slip on three different grounds was observed. The tangential force was measured by dynamometers fixed to tractor driving half-axle. The pulling force on the pulling rods was measured by dynamometer fixed to the pulling force. The tractor...

BACKGROUND Hand strength deficit following digital replantation is usually attributed to the mechanical deficiency of the replanted digit. Zone 1 replantation, however, should not be associated with any mechanical deficit, as the joint and tendon are intact. We evaluate short-term motor functions in patients who have undergone single-digit zone 1 replantation. METHODS A single-institution ret...

Sarcopenia is characterized by a lower skeletal muscle quantity, higher fat accumulation in the muscle, lower muscle strength, and lower physical performance. The most commonly used, low cost and accessible methods to assess skeletal muscle mass include dual energy X-ray absorptiometry (DEXA), anthropometry and bioelectrical impedance analysis (BIA). Magnetic resonance imaging (MRI), computeriz...

INTRODUCTION Hand strength is a good indicator of physical fitness and frailty among the elderly. However, there are no published hand strength references for Malaysians aged > 65 years. This study aimed to establish normative data for hand grip strength (HGS) and key pinch strength (KPS) for Malaysians aged ≥ 60 years, and explore the relationship between hand strength and physical ability. ...
