A Comparative Study of Pain Description, Emotional Discomfort and Health Perception in Patients With Chronic Pain Syndrome and Rheumatoid Arthritis
F Gaston-Johansson, G Johansson, R Felldin, H Sanne
The purpose of the present study was to compare pain description and emotional and psychosomatic discomfort in patients with chronic pain syndrome (CPS) and rheumatoid arthritis (RA) in order to identify special characteristic features in patients with CPS. Methods used were a Visual Analogue Scale, the McGill Pain Questionnaire, a new pain, ache and hurt assessment tool and a questionnaire relate ...

Trunk Strength, Back Muscle Endurance and Low-Back Trouble
T Nicolaisen, K Jørgensen
The strength and endurance of the trunk muscles was studied in relation to the extent of earlier low-back trouble (LBT) in a homogeneous, and occupationally active group. Twenty-four female and 53 male postmen with an occupational seniority of more than 2 years took part in the investigation. The cumulative lifetime prevalence, the one-year and the point prevalence of LBT were 67%, 62%, and 4% in ...

Shoulder externally rotating exercises with pulley apparatus. Joint load and EMG
K Harms-Ringdahl, U P Arborelius, J Ekholm, G Németh, K Schüldt
The mechanical load on the gleno-humeral joint and the muscular activity during shoulder external rotation resisted by a pulley apparatus were analysed using normalized, low-pass-filtered EMG recorded from the infraspinatus, deltoid, pectoralis major and trapezius muscles. The load moment about the longitudinal axis of the joint was compared with the distribution of maximum muscle moment over diff ...

Change in muscle force following electrical stimulation. Dependence on stimulation waveform and frequency
Stefanovska A, Vodovnik L.
Change in muscle force in healthy subjects due to electrical stimulation was accomplished with rectangular and sinusoidal currents. The pulse width of rectangular stimuli was 0.3 ms and repetition frequency was 25 Hz. The frequency of sinusoidal stimuli was 2 500 Hz, chopped by a 25 Hz rectangular signal. Thirteen healthy subjects were involved in the study and divided into three groups. The first ...

Simulation of Paretic Gait in Normal Subjects by Loading the Ankles
S T Eke-Okoro, L E Larsson, B Sandlund
Normal subjects were loaded with increasing weights (2-6 kg) applied around the ankles. During these conditions stride length increased in relation to velocity. The percentage duration of single support in relation to stride duration increased. Provided the same load was applied around both ankles increase was symmetrical. Consequently there was also an increase of swing as well as a decrease of s ...
