Influence of active kinetic treatment and passive balneotherapy on chronic low back pain.
81 patients with chronic low back pain aged 48.9 ± 8.4 years were treated for three weeks in a Rehabilitation Centre. Significant improvement of movement and reduction in pain were documented (p < 0.001). Body weight and cholesterol level decreased significantly.
Our patients evaluated the treatment in the following succession: Physiotherapeutic exercises, massage, movement therapy in a swimming pool, thermotherapy with peloids, exercise with spinal rehabilitation equipment, and electrotherapy. The electrotherapy contributed less to the improvement of disorders compared with other kinds of therapeutic treatment.
The patients were divided into the following groups:
Lumbar disc prolapse[s]persisting for less than 6 months,
Lumbar disc prolapse[s] persisting for more than 6 months,
Chronic difficulties caused by degenerative changes without lumbar disc prolapse.
No fundamental differences in the action of treatment [the effects of the treatments] in relation to the group and the chronicity of disorders were observed.
[Cannot say if singular prolapse or plural prolapses was intended.]
Physical activity in a cold environment
The man is a typical tropical animal. Rectal temperature (Tr) in winter swimmers during 20 min. swimming in water temperature (Tw) 4 °C decreased to 34.8 °C. Both blood pressures (BP) (systolic and diastolic) increased, plasma volume decreased (by 8%). The cold is a stress stimulus which triggers a marked catecholamine release. Norepinephrine (NE) increases BP, free fatty acids (FFA) mobilization, leucocytosis and spleen lymphocytesmobilization. The pituitary–adrenal axis is also activated. For the development of the cold adaptation, thyroid hormones are necessary. Catecholamine in cold and exercise causes reduction of the blood flow to the skin, intestines and kidneys. Both the plasma flow in the kidneys and glomerular filtration rate decrease, while protenuria increases. Blood glucose plays an important role in cold tolerance and exercise endurance. Hypoglycaemia suppresses shivering and significantly reduces Tr. Hence during endurance activities in a cold environment, refreshment through food intakeplays an important role.
Protection against heat losses is possible in two ways: Extension of the isolative ability of the body surface and Thermogenesis. Man intensifies body insulation through his actions, such as reduction of the body surface with the help of the shrink [I am not sure what is meant by this - does he mean weight-reduction?] and selection of suitable clothing.
Air temperature alone is not a valid indicator of thermal stress. A cold wind increases the rate of heat loss significantly, and the more humid the air, the greater the stress. Cooling a muscle causes its function to worsen. In hypothermia, exercise activity declines and this reduces metabolic heat production, whereby a potentially dangerous situation can occur. Seniors have lower heat production and less ability to avoid heat losses.
Hardening against cold is an instrument for the prevention of illnesses from cold. An increased immunity against respiratory infections was documented in subjects who regularly shower or bathe in cold water, as shown by the higher level of plasmatic IgA.
Hope this helps.
