Effect of Retrowalking Program Versus Whole Body Vibration in Patients With Chronic Knee Osteoarthritis
Condition: Knee Osteoarthritis
MeSH terms: Osteoarthritis; Osteoarthritis, Knee
Study type: Interventional

Summary: 
      Osteoarthritis is one of the most common degenerative joint disease that affects
      approximately more than 300 million people worldwide
    

Detailed description: 
      this study compare the efficacy of Retro-walking program and whole body vibration on
      quadriceps muscle torque,endurance, Balance and knee functional disability in patients with
      chronic unilateral knee Osteoarthritis . it has three groups. first group recieves The
      Routine physiotherapy program comprises a combination of closed kinetic chain and open
      kinetic chain exercises cause the least intraarticular inflammation, bone destruction, and
      pressure over the joint. the seconed group recieves routine physiotherapy and Retro-walking
      which is considered a safe Closed Kinematic Chain exercise since the compressive forces at
      the patello-femoral joint are reduced. it include improvement in muscle activation pattern,
      Reduction in adductor moment at knee during stance phase of gait and augmented stretch of
      hamstring muscle groups during the stride; all of these may have helped in reducing
      disability thus leading to improved function.It reduces quadriceps eccentric function, while
      the isometric and concentric quadriceps strength are preserved improved pain relief and
      aerobic fitness level, without aggravating symptoms following walking programs in patients
      with knee OA. the third group recieves routine physiotherapy program and Whole-body vibration
      training which is now a day's got its wider importance, especially in clinical cases. It has
      a role in maintaining balance, proprioception, blood circulation, and hormone level that
      enhances the effect on the neuromuscular system . it is a new type of exercise therapy, which
      mainly improves muscle coordination to optimize joint function .it is performed as a
      neuromuscular modality in muscle strength training . As it is safe, effective and potentially
      feasible treatment, WBV training has also been proposed for several musculoskeletal system
      diseases.

      the study ethical committee number is NO:P.T.REC/012/004280. the total sample size are 45
      (for 3 groups), 45 patients (15 patients per group).
    

Intervention name(s): routine physiotherapy program for knee osteoarthritis; Retro-walking program; whole body vibration training
Intervention type(s): Other; Other; Other
Intervention description(s): The Routine physiotherapy program comprises a combination of closed kinetic chain and open kinetic chain exercises, including straight leg raising, isometric quadriceps, isometric hip adduction, terminal knee extension, semi-squat, and leg press for 6 weeks.; Retro-walking program is about 10 min of supervised retro walking training 3 days a week for 6 weeks at their comfortable walking speed . The participants will be instructed to gradually increase their walking time up to 30 min over the 6-week period.; whole body vibration is 3 days per week for 6 weeks. During the training, the participants will perform static squat training barefoot on the platform with bent knees (30° and 60°). The distance between the feet was consistent with the shoulders. the duration time, sets and total time will be increased progressively over the 6-week.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: interventions; the first intervention: The Routine physiotherapy program comprises a combination of closed kinetic chain and open kinetic chain exercises, including straight leg raising, isometric quadriceps, isometric hip adduction, terminal knee extension, semi-squat, and leg press for 6 weeks.
the other intervention : Retro-walking program is about 10 min of supervised retro walking training 3 days a week for 6 weeks at their comfortable walking speed . The participants will be instructed to gradually increase their walking time up to 30 min over the 6-week period.
the last intervention is whole body vibration is 3 days per week for 6 weeks. During the training, the participants will perform static squat training barefoot on the platform with bent knees (30° and 60°). The distance between the feet was consistent with the shoulders. the duration time, sets and total time will be increased progressively over the 6-week.
