Shear stress measured on beds and wheelchairs
R H Goossens, C J Snijders, T G Holscher, W C Heerens, A E Holman
Local shear is understood to be one of the principal risk factors for the development of pressure sores. There is a need for a small deformable sensor that can measure the shear force between skin and deformable materials without disturbing the shear phenomenon. In the present study a new shear sensor is introduced with a contact area of 4. 05 cm2. A series of validation experiments was performed ...

Dynamometric assessment of the plantarflexors in hemiparetic subjects: relations between muscular, gait and clinical parameters
S Nadeau, D Gravel, A B Arsenault, D Bourbonnais, M Goyette
The aims of this study were to investigate, in 16 subjects with hemiparesis, the plantarflexor muscle performance of the paretic side and to determine the level of the relationships between muscular parameters, clinical measures and gait performance. A Biodex dynamometric system was used to evaluate static and dynamic torques, power and maximal rate of tension development of the plantarflexor musc ...

Non-reflex mediated changes in plantarflexor muscles early after stroke
F Malouin, C Bonneau, L Pichard, D Corriveau
The aims of this study were to determine whether changes in the non-reflex component of spastic plantarflexors had developed 2 and 4 months after stroke and to study their relationship with the level of impairment. One group of adults with hemiparesis (HPs) was tested 2 and 4 months after the onset of stroke, and data were compared with a control group (CTLs) tested once. Twenty-two patients (14 m ...

Prediction of recovery from upper extremity paralysis after stroke by measuring evoked potentials
H T Hendricks, G Hageman, J van Limbeek
Paralysis of the upper extremity is a severe motor impairment that can occur after stroke. Prediction of recovery from paralysis is difficult and is primarily based on subjective clinical evaluation. However, the integrity of the sensorimotor system can be assessed objectively and quantitatively by measuring evoked potentials. In this retrospective exploratory study, we evaluated the predictive va ...

Self-selected walking speed in patients with hemiparesis after stroke
U S Witte 1, J Y Carlsson
"Self-selected walking speed" was measured in 18 patients with hemiparesis after stroke and compared with that in a healthy control group. The average speed of the patient group for a 30 m walk was 0. 78 m/s (SD 0. 24) and of the control group 1. 69 m/s (SD 0. 05). The intraindividual variation for the patients was 0. 004 m/s and the interindividual variation 0. 37 m/s. For the controls, the corre ...

Reduced mobility in the cervico-thoracic motion segment--a risk factor for musculoskeletal neck-shoulder pain: a two-year prospective follow-up study
S Norlander, B A Gustavsson, J Lindell, B Nordgren
The aim of this study was to evaluate the variations in C7-T1 mobility in order to decide whether inverse C7-T1 function, defined as equal or less mobility in motion segment C7-T1 compared with T1-T2, could be used for prediction of neck-shoulder pain (NSP). One hundred and sixty-one female laundry workers participated in a prospective two-year follow-up study which included a self-report question ...

Force output and energy metabolism during neuromuscular electrical stimulation: a 31P-NMR study
G O Matheson, R J Dunlop, D C McKenzie, C F Smith, P S Allen
The purpose of this study was to determine the acute physiologic effects of two electrical stimulation protocols commonly used for muscle rehabilitation. Surface electrodes were used to provide 12 stimulations of the calf musculature. In protocol A the duty cycle was fixed at 1:1 (10-second stimulation: 10-second rest); for protocol B it was 1:5 (10-second stimulation: 50-second rest). We continuo ...

Effect of training on physical capacity and physical strain in persons with tetraplegia
A J Dallmeijer, M T Hopman, E L Angenot, L H van der Woude
The effects of quad rugby training on physical capacity and physical strain during standardized activities of daily living were investigated in 9 trained (A) and 5 untrained quad rugby players (B), and 7 inactive persons with tetraplegia (C) at 0, 3 and 6 months after the start of a quad rugby training program (1. 5h. wk[-1]). Physical capacity was measured as maximal isometric strength, peak powe ...

Isokinetic and psychophysical lifting strength, static back muscle endurance, and magnetic resonance imaging of the paraspinal muscles as predictors of low back pain in men
L E Gibbons, T Videman, M C Battié
Magnetic resonance imaging was used to determine the cross-sectional areas and the T2-weighted and proton density-weighted signal intensities of the paraspinal muscles in a group of 128 men, aged 35-63, who had varied histories of occupational and leisure-time physical activities. These measures, and the isokinetic lifting, psychophysical lifting, and static back muscle endurance tests were examin ...
