Training the unimpaired arm improves the motion of the impaired arm and the sitting balance in chronic stroke survivors

 Didn't your competent? doctor train you on this years ago? Oh, that's right, you DON'T have a functioning stroke doctor, do you? S/he knows nothing about recovery, but to quote this fuckingly lazy saying: 'All strokes are different, all stroke recoveries are different'! If you hear that from anyone you need TO GET THEM FIRED!

Here's proof for how long your complete stroke hospital is INCOMPETENT!

Abstract - 

Robot-assisted rehabilitation of stroke survivors mainly focuses on the impaired side of the body while the role of the unimpaired side in the recovery after stroke is still controversial. The goal of this study is to investigate the influence on sitting balance and paretic arm functions of a training protocol based on movements of the unimpaired arm. Sixteen chronic stroke survivors underwent nineteen training sessions, in which they performed active movements with the unimpaired arm supported by a passive exoskeleton. Performance of the trunk and upper limbs was evaluated before treatment, after treatment and at six months follow up with clinical scales and an instrumented evaluation. A reaching test executed with the exoskeleton was used to assess changes in performance of both arms. The treatment based on the unimpaired arm’s movements executed with a correct body posture led to benefits in control of the trunk and of both the trained and the untrained arm. The amount of impaired arm improvement in the Fugl-Meyer score was comparable to the outcome of robotic treatments focused directly on this arm. Our results highlight the importance of taking into account all body schema in the rehabilitation robotic program, instead of focusing only on the impaired side of the body.

INTRODUCTION Stroke is a cerebrovascular accident that often results in severe motor impairment and disability on the side of the body contralateral to the cerebral lesion. However, some studies highlight that the ipsilateral side also has deficits in muscle strength, coordination and dexterity [1-3] that are correlated with the level of impairment of the more affected contralateral side [4].

Research as well as rehabilitation, both traditional and robotic, focuses mainly on the most impaired arm [5, 6]. The role of the other arm in the recovery process is still controversial, ranging from approaches that promote the ‘no use’ [7] to methods that highlight a positive influence of the unimpaired arm motion [8]. Constraint Induced Movement Therapy (CIMT[9]) is based on limiting the movement of the unimpaired arm to promote the use of the other arm. CIMT seems to be effective at improving the most affected arm functions in daily life activities, but positive changes are observed mostly in stroke survivors with active wrist and finger movements, good cognitive abilities and limited spasticity [10]. Moreover these changes could be mainly due to an adaptation process rather than to recovery of normal functions and relearning upper arm use [11]. A recent review [12] found that CIMT is associated with some degree of recovery of motor functions, but does not reduce disability. This method indeed may improve functional abilities by increasing compensatory strategies along with a small reduction in impairment [13]. Conversely, there are other approaches that highlight a positive influence of the unimpaired arm motion on the more impaired side, such as the “cross education” method [14]. A recent review [15] examining the effects of cross-education in the rehabilitation of post-stroke hemiplegic survivors suggested that there is moderate evidence that cross- education has positive effects on muscle strength. Few other recent studies directly investigated if the training of the unimpaired side can influence body posture and impaired arm performance in stroke survivors. Exercises performed with the unimpaired arm seem to have positive effects on reducing spasticity [16] and enhancing balance and functions of the more affected arm [17]. Pandian et al. [18] showed also that this training could be effective not only for improving muscle strength, dexterity and coordination of the less-affected side directly involved in the training, but also for promoting the motor recovery of the more affected side. However, the evidence of the positive effects of this approach is still controversial. Moreover, several studies [19-24] highlighted limitations on the transfer of a learned skill from one arm to the other in healthy subjects. This work focuses on a training protocol based on active movements of the unimpaired arm in a population of chronic stroke survivors. We used a passive exoskeleton to facilitate a correct sitting posture and to propose exercises that required the recruitment of low back muscles with the goal of improving core stability.
