Motoneuron activity and muscle fibre type composition in hemiparesis
Jakobsson F, Grimby L, Edström L
The firing of single motor units (MUs) in musculus tibialis anterior (TA) was studied during maximal voluntary effort and maximal speed of walking in 10 patients with severe chronic hemiparesis and the findings compared to normal data. As shown in a previous study, the paralysed TA exhibited an increase in proportion of type 2 fibres as compared with normal muscle. Thus, 57% of the muscle fibres w ...

Gait evaluation in hemiparetic patients using subcutaneous peroneal electrical stimulation
Kljajić M, Malezic M, Aćimović R, Vavken E, Stanic U, Pangrsic B, Rozman J
In hemiparetic patients with an implantable peroneal stimulator for correction of drop foot the gait pattern was studied over several years. The gait parameters and M-waves of subcutaneously stimulated muscles were compared with the results obtained before implantation and their variation was observed over time. Of a group of 35 patients with previously implanted electrodes 19 were evaluated. Sign ...

Symmetry of electro- and acoustic myographic activity of the lumbar paraspinal muscles in normal adults
Wright F, Stokes MJ
The symmetry of paraspinal muscle activity was examined in 15 healthy adults (aged 31-60 years). Acoustic myography (AMG), which provides a measure of force, was recorded with electromyography (EMG) to assess electromechanical relationships during contraction. Bilateral recordings of EMG and AMG were made over the paraspinal muscles at the level of the 4th lumbar vertebra during a fatiguing test m ...

Work-related chronic neck impairment. Neck motion analysis in female traverse crane operators
Alund M, Larsson SE, Lewin T.
Twenty-one female steel industry traverse crane operators with long-term sick-leave (3 (1-8) years) due to chronic neck disability underwent careful analysis of case history, physical status and electrogoniometric three-dimensional recordings of active neck motion. Results were compared with those from working female crane operators having identical work posture and tasks and, further, with a grou ...

ORIGINAL REPORT
Mechanical performance, level of continuous contraction and muscle pain symptoms in home care personnel
Elert J, Brulin C, Gerdle B, Johansson H
The interrelationships between reported complaints, clinical status, mechanical performance and EMG pattern of the shoulder flexors and the knee extensors, respectively, during maximum dynamic contractions were investigated. A group of 97 randomly selected women employed in the home care service participated. Those who reported complaints had more clinical findings, such as reduced mobility, tende ...

Torque-velocity relation and muscle fibre characteristics of foot dorsiflexors after long-term overuse of residual muscle fibres due to prior polio or L5 root lesion
Tollbäck A, Knutsson E, Borg J, Borg K, Jakobsson F
Isokinetic foot dorsiflexion strength and muscle biopsy data from eight patients with overuse of tibialis anterior muscle (TA) fibres due to weakness after prior polio or L5 root lesion were compared to data from age and sex matched, healthy subjects. Concentric peak torque at an angular velocity of 30 degrees/s was 6-24 Nm in the patients and 15-34 Nm in the controls (p < 0.01). Muscle biopsies f ...

Rehabilitation and Parkinson's disease
Formisano R, Pratesi L, Modarelli FT, Bonifati V, Meco G.
In this study we evaluated the efficacy of physical therapy together with drug therapy in a group of parkinsonian patients, compared with a group of patients treated using drug therapy only. The physical therapy program lasted four months and included passive and active mobilization exercises, adopted for postural control and equilibrium, walking and prevention of contractures and ankylosis. The a ...
