Objectives
Narrative objectives1 Constraint induced movement therapy (CIMT) improves paretic upper extremity deficits in stroke patients. The short term benefit of CIMT for upper extremity deficits in stroke patients has been shown by many randomized controlled trials (Miller et al. 2010, Langhorn et al. 2011). Additionally, our previous study and few others have shown long term benefits (lasting 6 months to 2 years after the intervention) of CIMT for upper extremity deficits in stroke patients (Takebayashi et al. 2013, Wolf et al. 2006, Wolf et al. 2008). Plasticity of the central nervous system is one potential mechanism underlying the recovery of upper extremity function after CIMT. Several characteristics of association fibers (white matter tracts) evaluated by diffusion tensor imaging (DTI) scans have been related to the severity of motor deficits after central nervous system damage (Lee et al. 2005, Sterr et al. 2010, Radlinska et al. 2010). The fractional anisotropy (FA) value obtained from DTI scans is related to the integrity of association fibers. FA value reflects the random motion of water molecules, and low FA values reflect extensive damage to association fibers. In adult stroke patients, studies have shown a strong positive relation between the extent of motor deficit and FA quantified using DTI, particularly in the corona radiate (Zhu, 2010), cerebral crus (Koyama et al. 2013), and posterior limb of internal capsule (PLCI) (Qui et al. 2011). Additionally, FA value of the corticospinal tract predicted the short term benefit of CIMT for upper extremity motor deficits in adult stroke patients (Marumoto et al. 2013, Sterr et al. 2014). However, the mechanism by which CIMT induces long term benefits has not yet been studied. The aim of this study was to quantify the relation between the short and long term benefits of CIMT and the FA value of association fibers evaluated by DTI in adult chronic stroke patients with hemiparesis.

Key inclusion criteria Participants were chronic stroke patients (>7 months from stroke onset) with hemiparesis who received CIMT as part of their outpatient medical care at Hyogo College of Medicine Hospital between April 2010 and January 2016.
Key exclusion criteria 1) age <20 years at time of treatment, 2) bilateral or brain stem infarct or hemorrhage, 3) voluntary extension <10 degree at metacarpophalangeal and interphalangeal joints of three or more fingers and voluntary extension <20 degree at one wrist, 4) severe balance or walking disorder, indicated by the need for assistance for standing, walking, or using the toilet, 5) substantial use of the affected upper extremity before the intervention, indicated by a score >2.5 points on the Amount of Use (AOU) scale of the Motor Activity Log (MAL), 6) clear signs of dementia or cognitive disorder, indicated by a score <24 points on the Mini-Mental State Examination), 7) severe aphasia or apraxia that inhibited performance of the intervention, 8) presence of another uncontrolled medical condition or severe end-stage disease, 9) severe contraction around the shoulder, elbow, wrist, or finger, 10) absence of magnetic resonance imaging (MRI) data before the intervention, and 11) missing clinical assessment data at the 6-month follow-up time point.
