摘要
目的。研究中介绍了食指掌指关节运动参数测试用的独创操纵器，给出以设备进行的食指操控技能精确测量结果，并讨论未来以其作为诊断应用的可能性。
材料及方法。共43名年轻男性参与试验，并以上述独创设备进行运动精确性评估。受试者的任务在于多次以个别运动方式反复击向指定目标。由两项参数记录进行评估，包括达成目标的时间和路线等，由类间相关分析估计测量的可靠性。
结果。结果显示必须进行25-30次以上的重复，才能达成可靠的测量。试验结果显示受试者的运动学习可能性。
结果。使用操纵器得以可靠地评估运动准确性，但必须进行大量的测量，这对测试不会造成问题，因为单次测试所需时间仅1-1.5秒，不会造成掌指关节的运动疲劳。要将运动学习效果最小化，修改运动任务的执行条件似乎是合理的。设备创作者发现受试设备可应用于造成手掌功能效能受损的风湿性或神经性疾病的早期诊断。

Abstract

Functional limitations associated with RA-induce changes within the elbow joint and result in biomechanical disturbances. Objective data on the mobility of the affected articulation would facilitate the assessment of disease severity, selection of optimal physiotherapy interventions. Materials and Methods. Our study participants performed cyclic forearm extension and flexion elbow movements with different angular velocities. Biomechanical assessment comprised of spatiotemporal properties of cyclic movements. Spatial analysis of movement included the determination of movement direction (flexion, extension) and amplitude whereas the temporal analysis included the duration of particular movement phases as well as time-frequency analysis of a movement cycle. Results. The obtained results indicate that movement parameters in patients with rheumatoid arthritis differ significantly compared to normal ranges. Movement speed and amplitude as well as frequency and duration of movement are decreased. RA patients also exhibited considerable asymmetry of cyclic flexions and extensions of the elbow joint. Conclusion. It can be concluded that a biomechanical analysis using a manipulandum apparatus is a valuable diagnostic tool allowing objective evaluation of elbow function in rheumatoid arthritis. The measurements are highly sensitive, and hence, if performed in a larger patient population, they might help develop a classification of movement dysfunction in rheumatoid arthritis of the elbow joint. The analysis might also facilitate the assessment of hand dysfunction at various stages of RA development.

Assessment of the effects of rehabilitation interventions for patients with rhematoid arthritis using biomechanical analysis of elbow function

J. Rojczyk-Chmarek, J. Cieślińska-Świder, K. Gieremek, W. Cieśla, J. Polechoński – Assessment of the effects of rehabilitation interventions for patients with rhematoid arthritis using biomechanical analysis of elbow function. FP 2015; 15(1); 36-47

Abstract

Background. The aim of the investigations was to verify the effectiveness of a method of elbow function evaluation in patients with rhematoid arthritis. The method was expected to allow monitoring of disease progression and to help assess the effects of rehabilitation interventions.
Material and Methods. Cyclic flexion-extension movements in the elbow joint were examined in 82 individuals. The measurements were carried out with a computer-controlled unit for studying elbow movements (manipulandum). The study participants performed movements 1) of minimum speed, ie., the slowest possible movement, 2) of preferred speed consistent with patient preferences and habits, and 3) of maximum speed. The measurements were carried out before and after a 3-week rehabilitation program.
Results. The obtained results indicate that the rehabilitation intervention caused improvement in several parameters of the investigated movements. Movement amplitude (range of movement),  angular velocity (especially angular velocity of elbow extension) increased, the symmetry index decreased while no changes were observed in movement cycle duration for preferred and maximum speed.
Conclusions. The results indicate that this method of isokinetic movement evaluation allows objective assessment of articular pathologies and rehabilitation/pharmacotherapy outcomes. Our investigations suggest that, in order to obtain reliable information on the patient’s functional status, the measurements should be performed during preferred and maximum speed elbow movements. Information thereby obtained might be of considerable importance for selection of appropriate physiotherapy interventions.

The effect of music on selected hemodynamic parameters in patients suffering from unresponsive wakefulness syndrome

J. Polechoński, J. Rojczyk-Chmarek, K. Gieremek, M. Tyliba – The effect of music on selected hemodynamic parameters in patients suffering from unresponsive wakefulness syndrome. FP 2017; 17(1); 96-103

Abstract

Background. The aim of the study was to evaluate the effect of different music genres of different intensity levels on heart rate and arterial blood pressure in patients suffering from unresponsive wakefulness syndrome.
Material and methods. The study group comprised 16 patients in stable vegetative state; selected hemodynamic parameters were evaluated during and after exposure to different music genres of different intensity levels.
Results. The results revealed a significant stimulating effect of music played at 80 dB on several hemodynamic parameters of patients with unresponsive wakefulness syndrome. Disco music caused an increase in heart rate as well as elevation of systolic and diastolic pressures. Rock music only resulted in significant systolic blood pressure elevation.
No statistically significant alterations in hemodynamic parameters was noted when music was played at 60 dB.
Conclusions. Exposure to music may cause significant alterations of heart rate and arterial blood pressure of patients in a vegetative state – depending on music genre and intensity level. Changes in hemodynamic parameters might be indicative of an impact of music on the emotional state, which is closely associated with cardiovascular responses.
