Finger movements induced by transcranial magnetic stimulation change with hand posture, but not with coil position
1998
We attempted to map the representations of movements in 2 normal subjects by delivering five transcranial magnetic stimuli (TMS) with a focal coil to each of a grid of positions over the primary motor area (M1). Isometric forces were recorded from the contralateral index finger. Maps were made with the hand in a semiflexed “neutral” position, and with the thumb and index finger opposed in a “pincer” grip. The electromyogram (EMG) was monitored to ensure relaxation. The wrist was immobilized. In the neutral position, TMS at almost all positions produced abduction. Flexion was produced in the pincer position. Thus, while sensitive to changes in posture, TMS mapping may not be sensitive to the…
The treatment of wrist fractures with Epibloc System
2011
BACKGROUND Fractures of the distal extremity of the radius are the most common bone lesions of the superior extremity of the body, representing 17% of the fractures treated in First Aid facilities. The restoration of anatomical relationships in the radiocarpal joint is considered to be a prerequisite for good functional recovery. There are numerous methods of treatment of these fractures. The Epibloc system is a percutaneous endomedullary synthesis alternative to the plaster cast in wrist fracture treatment. MATERIALS AND METHODS The authors describe their experience with 81 fractures (63 type A2-3 fractures and 18 type C1) of the wrist treated with the Epibloc System (ES). The results were…
The Advantages of Type III Scaphoid Nonunion Advanced Collapse (SNAC) Treatment With Partial Carpal Arthrodesis in the Dominant Hand: Results of 5-ye…
2018
Introduction The SNAC wrist (Scaphoid nonunion advanced collapse) is one of the complications following scaphoid fractures treated conservatively and one of the causes of wrist arthritis that the hand surgeon has to face most frequently. In these cases surgical management is usually warranted. Materials and methods In the set time frame of 6 years we treated 15 SNAC wrist cases. On average patients underwent surgery five years after the trauma. All patients were treated via dorsal incision with partial carpal arthrodesis and total scaphoidectomy, associated with denervation of the posterior interosseous nerves. A plaster cast was applied to all patients for 3 weeks postoperatively. In the p…
Influence of somatosensory input on motor function in patients with chronic stroke.
2004
In healthy volunteers, reduction of somatosensory input from one hand leads to rapid performance improvements in the other hand. Thus, it is possible that reduction of somatosensory input from the healthy hand can influence motor function in the paretic hand of chronic stroke patients with unilateral hand weakness. To test this hypothesis, we had 13 chronic stroke patients perform motor tasks with the paretic hand and arm during cutaneous anesthesia of the healthy hand and healthy foot in separate sessions. Performance of a finger tapping task, but not a wrist flexion task, improved significantly with anesthesia of the hand, but not the foot. This effect progressed with the duration of anes…
Increased cross-education of muscle strength and reduced corticospinal inhibition following eccentric strength training.
2015
Aim: Strength training of one limb results in a substantial increase in the strength of the untrained limb, however, it remains unknown what the corticospinal responses are following either eccentric or concentric strength training and how this relates to the cross-education of strength. The aim of this study was to determine if eccentric or concentric unilateral strength training differentially modulates corticospinal excitability, inhibition and the cross-transfer of strength. Methods: Changes in contralateral (left limb) concentric strength, eccentric strength, motor-evoked potentials, short-interval intracortical inhibition and silent period durations were analyzed in groups of young ad…
Three-year (2014-2016) activity report of the Replantation Service for hand amputations in Poland
2018
W pracy przedstawiono podsumowanie 32 miesięcy działalności Serwisu Replantacyjnego dla amputacji rąk w Polsce od stycznia 2014 roku do sierpnia 2016 roku. W analizowanym czasie zgłoszono łącznie 568 przypadków – amputacji, częściowych amputacji i innych rozległych urazów kończyn górnych, z czego zaakceptowano 354 przypadki (62%), a odrzucono 214 (38%). Wśród 354 wszystkich zaakceptowanych przypadków znalazło się 167 całkowitych amputacji (47%), 142 amputacji niecałkowitych (40%) i 45 (13%) innych ciężkich urazów, które zagrażały utratą kończyny. W większości ofiarami byli mężczyźni o średniej wieku 39 lat. Najwięcej pacjentów przeszło amputacje kilku palców i kciuków – łącznie 229 (65%) os…
Hand trajectory formation during whole body reaching movements in man.
1998
End-effector trajectory formation was studied during a reaching movement using the whole body. The movements of various parts of the body were measured with the optoelectronic ELITE system. Wrist reaching movement paths showed noticeable curvatures. The analysis of various marker onset latencies revealed that the wrist was the last to move, always after the head, knee or trunk, suggesting a subordinate role of the focal component with respect to the primary role of the equilibrium component. These results suggest that reaching wrist movements are subjected to whole-body equilibrium constraints in addition to constraints placed upon end-effector kinematics or the dynamic optimization of uppe…
Structural validity of the Boston Carpal Tunnel Questionnaire and its short version, the 6-Item CTS symptoms scale : a Rasch analysis one year after …
2020
Abstract Background: The Boston Carpal Tunnel Questionnaire (BCTQ) and its shorter version, the Six-Item Carpal Tunnel Symptoms Scale (CTS-6), are widely used for assessing function and/or symptoms in patients with carpal tunnel syndrome. This study examined the structural validity of the BCTQ and CTS-6 among patients who had undergone surgery for treatment of carpal tunnel syndrome. Methods: The data for this cross-sectional analysis were obtained from 217 adult patients who had undergone carpal tunnel release surgery one year earlier. All patients completed the CTS-6, Symptom Severity Scale (SSS) and Functional Status Scale (FSS) of the BCTQ at 12 months after surgery. The Rasch Measureme…
Absolute Accelerometer-Based Intensity Prescription Compared to Physiological Variables in Pregnant and Nonpregnant Women
2020
Estimation of the intensity of physical activity (PA) based on absolute accelerometer cut points (Cp) likely over- or underestimates intensity for a specific individual. The purpose of this study was to investigate the relationship between absolute moderate intensity Cp and the first ventilatory threshold (VT1). A group of 24 pregnant and 15 nonpregnant women who performed a submaximal incremental walking test with measures of ventilatory parameters and accelerations from three different accelerometers on the wrist (ActiGraph wGT3X-BT, GENEActiv, Axivity AX3) and one on the hip (Actigraph wGT3X-BT) were analyzed. Cp were determined corresponding to 3 metabolic equivalents of task (MET), usi…
Perceived effects of health status on sexual activity in women and men older than 50 years
2014
Background Sexual activity and enjoyment are considered to be important components of quality of life (QOL) for adults of all ages. However, limited data are available on the effects of health status on sexual activity in women and men older than 50 years. Thus, our aim was to explore the perceived effects of health status on sexual activity in women and men older than 50 years. Methods For this purpose we used data from an age and gender matched control study initially designed to study QOL in patients with low-energy wrist fracture. We investigated patients with wrist fractures older than 50 years (n = 181), as well as age- and gender-matched controls (n = 226), who participated in the QO…
