PMID 28210066WHAT IT FOUND
In one woman with Parkinson's disease, balance and hand scores improved during interactive metronome training, but this case report cannot show the training caused them.
Key findings
01The Berg balance scale score was 46 at pre-test and 52 at post-test in the text, while Table 1 reports 56 at post-test.
02Wolf motor function test functional ability scores were 4.73 at pre-test and 4.93 at post-test for the right hand, and 4.66 at pre-test and 4.93 at post-test for the left hand.
03Box-and-block test scores for the right hand were 54, 66, and 71.5 at first baseline, treatment, and second baseline; left-hand scores were 50.3, 65.5, and 74.8.

What it does not show
Only one participant was studied, so the findings cannot be generalized to all stages of Parkinson's disease. No comparison group was used, and the single-participant design does not show that the training caused the score changes. The number of treatment sessions is not stated. The Berg balance scale post-test is reported as 52 in the text and 56 in Table 1. The box-and-block left-hand scores are reported as 50.3, 65.5, and 74.8 in the text and 50.25, 65.53, and 74.75 in Table 2.
The easy way to misread this
Do not conclude that interactive metronome training improved Parkinson's disease symptoms. This was one participant in a single-participant case report, the number of treatment sessions is not stated, and the Berg balance scale post-test is reported as 52 in the text but 56 in Table 1.
