[Purpose] To investigate the suitability and reliability of the Borg Category Ratio Scale (CR-10) for isometric contraction exercises performed by polio survivors. [Subjects] The subjects were 15 polio survivors and 45 age-matched normally healthy persons. [Methods] Subjects performed isometric contraction exercise for the knee extensors. The exercise intensity (CalcVal) was derived from the maximum muscle strength, and measured the Borg CR-10 value when reproducing the exercise using CalcVal as visual feedback. Then, we measured muscle strength (RealVal) when performing exercise with the Borg CR-10 value as an index of exercise intensity. We investigated the agreement of CalcVal and RealVal, and the correlation between the Borg CR-10 value and exercise intensity. [Results] Moderately high agreement was found between CalcVal and RealVal, and the Borg CR-10 value correlation with exercise intensity was high. [Conclusion] The results suggest that for polio survivors, an exercise intensity of Borg CR-10 value=4, quite strong, can prevent “muscle overuse and disuse”. - Systematic Reviews of Sports Physiotherapy

To clarify the evidence in the field of sports physiotherapy, we selected and analyzed 76 systematic reviews of sports physiotherapy published since 2000. Reports on, knees and shins (n=26), ankles and feet (n=20) were greater in number than other body parts, while pain, weakness, and motor tolerance were common topics. As physical therapy interventions, stretching, mobilization, massage, muscle strengthening, orthosis, taping, splint and physical medicine were common themes.

In this study, we measured sitting posture and forces applied to the buttocks with a sitting device that can tilt each seat and backrest four kinds. In the sitting device used for measurement, all subjects exceeded 200mmHg at buttock pressure and exceeded 100 mmHg at back pressure. The use of ROHO cushion reduced the pressure of the sacrum, the left sciatica and back, but the shear force increased. Even with ROHO cushion, the pressure of the sacrum was 48-60mmHg. The shear force of the buttocks at the time of sitting on the ROHO cushion became larger in the frontal plane than in the sagittal plane. A correlation was found between the change in posture and the external force occurring in the buttocks, but the changes in posture due to the seat inclination and the back inclination used in this study were not siginificant.
