description | Background
This two‐part study explored the safety, feasibility, and efficacy of a mild–moderate resistance isometric leg exercise program in ambulatory boys with Duchenne muscular dystrophy (DMD).
Methods
First, we used a dose escalation paradigm with varying intensity and frequency of leg isometric exercise to determine the dose response and safety in 10 boys. Second, we examined safety and feasibility of a 12‐wk in‐home, remotely supervised, mild–moderate intensity strengthening program in eight boys. Safety measures included T2 MRI, creatine kinase levels, and pain. Peak strength and function (time to ascend/descend four stairs) were also measured.
Results
Dose‐escalation revealed no signs of muscle damage. Seven of the eight boys completed the 12‐wk in‐home program with a compliance of 84.9%, no signs of muscle damage, and improvements in strength (knee extensors P |

Dose‐escalation revealed no signs of muscle damage. Seven of the eight boys completed the 12‐wk in‐home program with a compliance of 84.9%, no signs of muscle damage, and improvements in strength (knee extensors P < .01; knee flexors P < .05) and function (descending steps P < .05).
Conclusions
An in‐home, mild–moderate intensity leg exercise program is safe with potential to positively impact both strength and function in ambulatory boys with DMD.</description><identifier>ISSN: 0148-639X</identifier><identifier>EISSN: 1097-4598</identifier><identifier>DOI: 10.1002/mus.27137</identifier><identifier>PMID: 33295018</identifier><language>eng</language><publisher>Hoboken, USA: John Wiley & Sons, Inc</publisher><subject>Child ; Clinical Neurology ; Creatine ; Creatine kinase ; Creatine Kinase - blood ; Damage ; Duchenne muscular dystrophy ; Duchenne's muscular dystrophy ; Dystrophy ; Exercise ; Exercise Therapy - methods ; Feasibility Studies ; Flexors ; functional ability ; Hamstring Muscles - diagnostic imaging ; Humans ; in‐home exercise program ; isometric exercise ; Kinases ; Knee ; Leg ; Life Sciences & Biomedicine ; Magnetic Resonance Imaging ; Male ; Muscle contraction ; Muscle Strength ; Muscle, Skeletal - diagnostic imaging ; Muscles ; Muscular dystrophy ; Muscular Dystrophy, Duchenne - blood ; Muscular Dystrophy, Duchenne - diagnostic imaging ; Muscular Dystrophy, Duchenne - rehabilitation ; Neurosciences ; Neurosciences & Neurology ; Pain ; Quadriceps Muscle - diagnostic imaging ; Safety ; Safety measures ; Science & Technology ; Stairways ; Strengthening ; T2 MRI ; Treatment Outcome</subject><ispartof>Muscle & nerve, 2021-03, Vol.63 (3), p.320-326</ispartof><rights>2020 Wiley Periodicals LLC</rights><rights>2020 Wiley Periodicals LLC.</rights><rights>2021 Wiley Periodicals, LLC.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>true</woscitedreferencessubscribed><woscitedreferencescount>30</woscitedreferencescount><woscitedreferencesoriginalsourcerecordid>wos000600856000001</woscitedreferencesoriginalsourcerecordid><citedby>FETCH-LOGICAL-c4437-84f394e679d6a6e6a70d754c56ff7e62194914fdb6dce9fe132feb611370d6bf3</citedby><cites>FETCH-LOGICAL-c4437-84f394e679d6a6e6a70d754c56ff7e62194914fdb6dce9fe132feb611370d6bf3</cites><orcidid>0000-0002-7302-1756</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fmus.27137$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fmus.27137$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>230,315,782,786,887,1419,27933,27934,39267,45583,45584</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/33295018$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Lott, Donovan J.</creatorcontrib><creatorcontrib>Taivassalo, Tanja</creatorcontrib><creatorcontrib>Cooke, Korey D.</creatorcontrib><creatorcontrib>Park, Hyunjun</creatorcontrib><creatorcontrib>Moslemi, Zahra</creatorcontrib><creatorcontrib>Batra, Abhinandan</creatorcontrib><creatorcontrib>Forbes, Sean C.</creatorcontrib><creatorcontrib>Byrne, Barry J.</creatorcontrib><creatorcontrib>Walter, Glenn A.</creatorcontrib><creatorcontrib>Vandenborne, Krista</creatorcontrib><title>Safety, feasibility, and efficacy of strengthening exercise in Duchenne muscular dystrophy</title><title>Muscle & nerve</title><addtitle>MUSCLE NERVE</addtitle><addtitle>Muscle Nerve</addtitle><description>Background
