Treadmill walking with partial body weight support versus floor walking in hemiparetic subjects

It seems there was no objective analysis of the walking disability. If so, nothing here is repeatable.  I found these body weight supported systems useless, my spasticity in my legs required my full body weight to counteract that.  But my therapists strapped me in these regardless. It is the one size fits all approach.

ABSTRACT.

Treadmill walking with partial body weight support versus floor walking in hemiparetic subjects. Arch Phys Med Rehabil 1999;80: 421-7. 
Objective: 
To compare the gait of hemiparetic subjects walking on a treadmill with various body weight supports and walking on the floor. 
Design: 
Hemiparetic subjects walked on a treadmill, secured in a harness, with no body weight support and with 15% and 30% body weight relief, and walked on a floor. Setting: Kinematic laboratory of a department of rehabilitation. 
Subjects: 
Eighteen hemiparetic stroke patients. 
Main Outcome Measures: 
Gait cycle parameters and kinesiologic electromyogram of six muscles of the affected side and of two muscles of the nonaffected side. 
Results: 
On the treadmill, patients walked more slowly because of a reduced cadence, with a longer single stance period of the paretic limb, more symmetrically, and with a larger hip extension (multivariate profile analysis, p < .05). The mean functional activities of the gastrocnemius muscle and of the first crest of the erector spinae of the paretic side were smaller on the treadmill (univariate test, p < .05). Further, the premature activity of the gastrocnemius muscle, indicating spasticity, was less on the treadmill (univariate test, p < .05); correspondingly the qualitative muscle pattern analysis re- vealed less co-contraction between the gastrocnemius and tibialis anterior muscles in 11 of the 18 subjects. 
Conclusions: 
Treadmill training with partial body weight support in hemiparetic subjects allows them to practice a favorable gait characterized by a greater stimulus for balance training because of the prolonged single stance period of the affected limb, a higher symmetry, less plantar flexor spasticity, and a more regular activation pattern of the shank muscles as compared with floor walking. 0 1999 by the American Congress of Rehabilitation Medi- cine and the American Academy of Physical Medicine and Rehabilitation
