Effects of the Innovation Pulley-Wheel 2 in 1, Regarding the Range of Motion and Pain Score in Patient Frozen Shoulder

Abstract

          This quasi-experimental study was aimed to evaluate the effect of the innovation pulley-wheel 2 in 1, regarding the range of motion and pain score, in comparison with the traditional pulley and the shoulder wheel.  The sample size was 60 patients with frozen shoulders. This evaluation took place from January through December 2023 at the physical therapy department of the Phrachomklao Hospital in Phetchaburi.  The participants were matched 30 pairs to the experimental group and the control group by simple random sampling. The research tools were the innovation pulley-wheel 2 in 1, and the traditional pulley and the shoulder wheel. The participants were treated 3 times/week duration 40 minutes during the 8 weeks. The program included 1) the hot pack 2) mobilization technique. In addition, the experimental group received exercise consisting of the innovation pulley-wheel 2 in 1, while the control group received exercise by the traditional pulley and shoulder wheel. The outcomes were measured by using the range of motion and the shoulder pain by the visual analog scale before and after treatment. The data were used analysis along with a dependent t-test and independent t-test. The findings were the innovation pulley-wheel 2 in 1 increased significant the range of motion in flexion and abduction direction in the experimental group after treatment (p-value=0.05) and increased significant the range of both flexion and abduction motion in the experimental group more than the control group (p-value=0.05), mean of Flexion and abduction 178.13 ± 0.516, 166.2 ± 3.8 and 177.73 ± 0.59, 163.8 ± 4.4 degree. The visual analog scale showed that after the treatment were less than significant before the treatments both groups, but no significant difference between groups. The study concluded that the innovation pulley-wheel 2 in 1 could improve the range of motion of shoulder flexion and abduction direction better than the traditional pulley and wheel procedure; however, the visual analog score was not significant in patients with frozen shoulder. The innovation pulley-wheel 2 in 1 was a good choice for shoulder exercise.
