Competing interests: KAV, BHC, and SMZ declare employment at Alere Wellbeing, the provider of quitline services in this study. Ethics approval: Indiana University Institutional Review Board approved the study protocol (approval ID number 1009001892). Provenance and peer review: Not commissioned; externally peer reviewed. Data sharing statement: The full trial protocol is available on request, from the lead author. iConsistent with recommendation of the SRNT Subcommittee on Biochemical Verification (2000) for large scale (ie, >1000 participans), population-based studies with limited face-to-face contact and studies where the optimal data collection methods are through the mail, telephone, or internet, biochemical validation of abstinence was not obtained.""Architectural adaptations of the lower limb muscles in individuals with CP compared to typically developing individuals include (1) reduced muscle volume,14�C16 (2) increased muscle fascicle stiffness,17 (3) reduced18�C20 or similar15 21 muscle fascicle lengths, (4) increased intramuscular fat22 and (5) increased Achilles tendon length.23 Alterations to muscle architecture in individuals with CP begin to occur within the first 5?years of life14 24 25 which may progress into adulthood.23 Muscle architecture is the primary determinant of muscle function26 and the specific musculotendinous adaptations in individuals with CP may contribute to a loss of muscle click here strength8 27 28 and functional ability.29 The decline in force-generating capacity of the muscle has been directly attributed to a reduced muscle volume.23 Increased muscle fascicle stiffness17 may also result in the inability of the muscle fascicles to reach lengths favourable for high force production.26 Furthermore, weaker calf muscles with stiffer muscle fascicles interacting with a longer Achilles tendon in series, as observed in individuals with CP,17 23 27 may result in altered muscle function during walking.30 A higher intramuscular fat content translates to a reduced proportion of contractile tissue within the muscle.22 This reduced muscle quality may therefore be a contributing factor to muscle weakness and have implications for functional performance in individuals with spastic CP. The alterations to the musculotendinous unit may also contribute to the reduced power generation during gait,31 and diminished anaerobic performance32 in individuals with CP. Moderate to high correlations have also been reported between strength and walking speed (r=0.61)33 and between strength and activity limitations (r=0.70�C0.83)5 suggesting that muscle weakness plays a role in the mobility difficulties associated with spastic CP. Neural factors underlying reduced muscle force and the resultant joint torque in individuals with CP include reduced excitatory drive to the agonist muscle and increased coactivation of antagonists.
