Maximal isometric knee strength increased more in HG than in C (<jats:italic>p<\/jats:italic> = .03) and with increasing guidance (<jats:italic>p<\/jats:italic> = .03). The effect was mainly the result of participants with low initial strength. Walking speed increased more for HG than for C (<jats:italic>p<\/jats:italic> = .02) and than for MG (<jats:italic>p<\/jats:italic> = .06). No statistically significant improvements were seen on other functional tests. In summary, the study shows a trend toward better results with more supervision, but more and larger studies are needed to confirm this.<\/jats:p>","DOI":"10.1123\/japa.13.1.5","type":"journal-article","created":{"date-parts":[[2016,8,10]],"date-time":"2016-08-10T13:20:38Z","timestamp":1470835238000},"page":"5-22","source":"Crossref","is-referenced-by-count":58,"title":["The
