Good and Bad News About Hand Recovery

I do not have a high level of hand recovery so I look for studies that do not cherry-pick high functioning stroke survivors to test the efficacy of hand rehab.  Many studies with positive results start with stroke survivors who already have beginning finger and thumb movement.  To decide how excited to get I look at the outcome measures to see if the results apply to someone like me.

Franck studied stroke survivors with no spontaneous hand recovery (1).  Group 1 was taught to keep the affected arm/hand in an "optimal condition" and told what to do when discomfort occurred. Before rehab, the highest score on the Fugl-Meyer test was a 9 out of 66.  After 6 weeks of rehab for 4.5 hours per week, the highest Fugl-Meyer score was a 20 which can be achieved with
NO hand or wrist movement.  After rehab, object manipulation on the Action Research Arm Test (ARAT) improved from 0 to 1 out of 57 for one subject.  This is bad news.

Before rehab, Group 2 had a small amount of hand use during object manipulation as seen by ARAT scores that ranged from 1 to 9 out of 57 (1). Group 2 was given "high-intensity" therapy for
6 hours per week for 6 weeks to use their hand during functional tasks.  After rehab the highest ARAT score improved from 9 to 42 out of 57.  This level of improvement can be achieved ONLY by gaining the ability to pick up objects like a ball.  After rehab, the highest Fugl-Meyer score improved from 25 to 54 out of 66.  This dramatic improvement can ONLY be achieved with hand and wrist movements.  Turning a little bit of spontaneous recovery into the ability to pick up objects is good news.
