Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will participate in 5-week hydrotherapy (group A) or manual therapy (group B) programme 2 times a week. Each session will last for approximately 45 minutes.
Hydrotherapy (Watsu) will take place in a pool with a warm water (32-34 degrees Celsius). Before the first session the therapist will explain how the Watsu therapy session starts and ends. The therapist and patient dressed in swimwear together will enter the pool. The patient, supported by the therapist lies on his/her back in the water and closes his/her eyes. Supported mainly by the forearms placed under the head and initially under the pelvis the therapist moves the patient through the water in flowing, rhythmical motions which includes intermittent gentle massage and stretching. During each session the therapist will perform the same techniques in a sequence recommended by Worldwide Aquatic Bodywork Association (WABA): breath dance, slow offering, freeing the spine, one leg slow offering, two legs slow offering, accordion, accordion in rotation, near leg rotation, far leg rotation, arm leg rock, thigh press, arm play and lift, chest opening, leg press, arm back around, lengthening spine, spine pull, undulating spine, hip push, seaweed, figure 4 (it is the name of movement sequence), breath dance, wall return. There should be no conversation between the patient and therapist during therapy, however patient should inform about any pain during therapy. The distance between the patient and the therapist ranges from full arms length to close cradling. After a session of approximately 45 min, the therapist assists the patient to a seated position in the pool. Next, the patient shower, dress, rest for 5–15 min and then leave.
Manual therapy in group B will take place indoor. It will consists of hip joint traction, post isometric muscle relaxation of identified shortened muscles surrounding the hip joint, trigger point therapy. In both groups all manipulations will be repeated until the therapist stated optimal results of the session.
In both groups a physical therapist will administrate the intervention. It will be one-on-one face-to-face exercise session. There will be an attendance list to monitor patients adherence to intervention.

Comparator / control treatment
The comparator group will be manual therapy group (group B).

Manual therapy intervention (group B) will be performed 2 times per week for 5 weeks. Each session will last for approximately 45 minutes. Manual therapy will take place indoor. It will consists of hip joint traction, post isometric muscle relaxation of identified shortened muscles surrounding the hip joint, trigger point therapy. All manipulations will be repeated until the therapist stated optimal results of the session.
Physical therapist will administrate the intervention. It will be one-on-one face-to-face intervention. There will be an attendance list to monitor patients adherence to intervention.

Summary
Brief summary
The goal of the study is to assess and compare changes in functional status in patients with hip osteoarthritis. Study participants will be patients with hip osteoarthritsis, stage II before arthroplasty recruited from the Department of Ortopedic Surgery, Specialistic Hospital in Szczecin Zdunowo and the Department of Ortopedic Surgery Specialistic Hospital in Gorzow Wielkopolski. 60 patients will be randomised into 2 groups - the hydrotherapy group - patients will undergo the 5-week hydrotherapy (Watsu) 2 times a week, the manual therapy group will undergo the 5-week manual therapy 2 times a week. Hydrotherapy (Watsu) will take place in a warm (34 degrees od Celsius) pool. During each session the therapist will perform the same techniques in a sequence recommended by Worldwide Aquatic Bodywork Association (WABA). Manual therapy will consists of hip joint traction, post isometric muscle relaxation of identified shortened muscles surrounding the hip joint, trigger point therapy. In both groups all manipulations will be repeated until the therapist stated optimal results of the session.
Before and after 5 weeks, 1 and 3 month after intervention completion patients will undergo the following examinations: functional status, pain level, hip range of motion, gluteus medius, tensor fasciae latae, lumbar erector spinae muscles activity (sEMG). Statistical analysis will be performed with the use of Statistica 10 software. Study has been approved by the research Bioethics Comittee.
