Comparing Hot Pack, Short-Wave Diathermy, Ultrasound, and TENS on Isokinetic Strength, Pain, and Functional Status of Women with Osteoarthritic Knees: A Single-Blind, Randomized, Controlled Trial
Cetin N , Aytar A , Atalay A , Akman MN : Comparing hot pack , short-wave diathermy , ultrasound , and TENS on isokinetic strength , pain , and functional status of women with osteoarthritic knees : a single-blind , r and omized , controlled trial . Am J Phys Med Rehabil 2008;87:443–451 . Objective : To investigate the therapeutic effects of physical agents administered before isokinetic exercise in women with knee osteoarthritis . Design : One hundred patients with bilateral knee osteoarthritis were r and omized into five groups of 20 patients each : group 1 received short-wave diathermy + hot packs and isokinetic exercise ; group 2 received transcutaneous electrical nerve stimulation + hot packs and isokinetic exercise ; group 3 received ultrasound + hot packs and isokinetic exercise ; group 4 received hot packs and isokinetic exercise ; and group 5 served as controls and received only isokinetic exercise . Results : Pain and disability index scores were significantly reduced in each group . Patients in the study groups had significantly greater reductions in their visual analog scale scores and scores on the Lequesne index than did patients in the control group ( group 5 ) . They also showed greater increases than did controls in muscular strength at all angular velocities . In most parameters , improvements were greatest in groups 1 and 2 compared with groups 3 and 4 . Conclusions : Using physical agents before isokinetic exercises in women with knee osteoarthritis leads to augmented exercise performance , reduced pain , and improved function . Hot pack with a transcutaneous electrical nerve stimulator or short-wave diathermy has the best outcome
