Study on the mechanical parameters of neuromuscular joint facilitation rehabilitation techniques for lumbar...

[Purpose] To measure the reliability of and quantify the force on the spinous process during lumbar neuromuscular joint facilitation using mechanical measuring gloves. [Participants and Methods] We recruited 12 healthy participants. The operator wore a mechanical measuring glove and performed evaluations in the four modes of neuromuscular joint facilitation of the lumbar spine. The mechanical glove was used to measure the force applied by the fingers on the spinous process during the intervention. [Results] The reliability of measuring the supraspinous force during lumbar neuromuscular joint facilitation with mechanical gloves was found to be good; the force was 30.9 ± 6.6 N for front lifting, 37.1 ± 9.1 N for rear descent, 36.8 ± 9.0 N for forward descent, and 24.6 ± 4.7 N for rear lifting. Overall, the average force was 32.3 ± 9.0 N. No statistical difference was observed between passive and resistance motion. [Conclusion] This study confirmed that the measurement of the force on the spinous process in lumbar neuromuscular joint facilitation using mechanical measurement gloves has good reliability. Furthermore, we determined the average force exerted on the spinous process during lumbar neuromuscular joint facilitation and quantified the operation specifications of this manipulation were.
