I suggest that the gravity reduction is the main reason for the benefit and you can do the same thing with
my cane exercises. But don't listen to me, I'm not medically trained and those exercises are obviously too dangerous to be used without your doctors ok. Good luck on getting that approval.

Abstract
OBJECTIVE:
To evaluate the efficacy of a
gravity-supported, computer-enhanced device (
Armeo(®)Spring) for upper
limb rehabilitation in chronic stroke patients.
MATERIAL AND METHODS:
We
included 23 chronic hemiparetic patients (chronicity: 328 ± 90.8 days;
distribution: 17 men and 6 women) aged 54.6 ± 9.5 years, who had
sustained ischaemic (n=12) or haemorrhagic (n=11) stroke. All patients
completed 36 one-hour sessions using the Armeo(®)Spring system. Arm
movement was assessed at the beginning and end of the treatment
programme, and once more 4 months later. Main outcome measurements
covered structure, activity, and function, as per the International
Classification of Functioning, Disability and Health: Modified Ashworth
Scale, Motricity Index (MI), Fugl-Meyer Assessment Scale (FM), Motor
Assessment Scale (MAS), Manual Function Test (MFT), and Wolf Motor
Function Test (WMFT).
RESULTS:
Repeated measures ANOVA
showed significant improvement (time effect) for all function scales
(P<.01 for FM and MI) and activity scales (P<.01 for MAS, MFT and
WMFT-ability, and P<.05 WMFT-time) without significant changes in
muscle tone. The post-hoc analysis (Bonferroni) showed different
evolutionary patterns for function and activity measurements, and clear
benefits related to Armeo(®)Spring training, especially on activity
scales.
CONCLUSIONS:
Armeo(®)Spring is an effective tool
for rehabilitating the affected arm in patients with hemiparesis
secondary to ictus, even in the chronic stage.
