DM, and recovery less favorable for these people too

59
Q

How to best treat adhesive capsulitis most recent evidence

74
Q

What did Suetta et al find about THA rehab in groups with standard rehab (home-based, exercises without resistance) standard rehab plus NMES, and SR plus resistance training

A

Length of stay shorter for RT, functional skills improved for both RT and NMES. Quad cross-sectional area increased in RT and NMES, but more with RT, but decreased SR. Basically rehab with closely monitored RT is the best

75

A

At 4 -12 months gave experimental group individual home-based program for 8 weeks, control group just had ROM and isometric exercises, the experimental group had improvement on function, strength, postural stability, suggesting return to PT after several months should be considered.
