The Measurement of Force and Endurance during Wheelchair Propulsion in Paraplegics Using BTE Work Simulator

OBJECTIVE: To evaluate the force, endurance and influencing factors for wheelchair propulsion in paraplegics using BTE work simulator, and to find out a better method improving fitness levels for the paraplegics. METHOD: Seventeen paraplegic men were enrolled for the study. Isometirc and isotonic strength and dynamic endurance levels for wheelchair propulsion were measured using BTE work simulator. Neurological and demographical characteristics of patients were collected by personal interviews and direct examinations. RESULT: The spinal cord injured level showed a significant correlation with dynamic endurance (r=0.503, p<0.05) but not with the isometric and isotonic strength. The total duration of wheelchair use showed a significant correlation with the isotonic strength (r=0.497, p<0.05), but not with the isometric strength and dynamic endurance. The age and outdoor activities or exercise time during one week showed no significant correlation. CONCLUSION: Spinal cord injured level positively correlated with dynamic endurance. Both cardiorespiratory effect and trunk balance may influence this correlation. The total duration of wheelchair use wasn't correlate with dynamic endurnace. It seems to be more advisable trunk balance training goes with dynamic endurance training in rehabilitation program.

A Study of Serum Lipid Profiles in Paraplegics

Generally, regular exercise is known to help to improve lipid metabolism. In the spinal cord injured, relative inactivity to able-bodied person causes altered lipid profiles and, in turn, possibly increases cardiovascular mortality. We performed this study to measure serum lipid profiles in paraplegics and to evaluate effect of regular exercise on lipid profiles. The subjects are 21 paraplegics, who are divided into 2 groups, 10 SCI athletes and 11 SCI non-athletes. The serum levels of lipoproteins in these subjects were measured and compared each other. The levels of serum HDL-cholesterol were lower in the order of, non-athlete group, athelte group, and normal control group, and there was a significant difference between athlete and non-athlete groups. The ratios of total cholesterol to HDL-cholesterol were higher in the order of non-athlete group, athlete group, and normal control group, and there was a significant difference between control and non-athlete groups. The serum levels of total cholesterol, LDL-cholesterol, and triglyceride in three groups showed no significant differences. In conclusion, serum levels of HDL-cholesterol were positively affected by regular exercise, and it is advised that the HDL-cholesterol levels of spinal cord injured should be checked regularly for follow-up examinations.
