Measures


Green et al. [20]

• Hydrotherapy and home exercise

• Home exercise only

• 47 subjects referred from specialist clinics (mean age, 66.8 years)

• OA hip diagnosed with radiology (with approximately 75% of subjects moderate to severe). Hip pain ≥ 6 months. Normal ESR and negative rheumatoid factor

• No baseline pain measures provided.

• Hydrotherapy and home exercise vs. home exercise only

• Two groups of subjects:

    Hydrotherapy and home exercise:
(24 subjects) home exercise 2× daily and hydrotherapy 2× per week for 6 week

    Home exercise only:
(23 subjects): 2× daily for 6 weeks with compliance monitored

• 3 mobility and 2 strengthening exercises; 10 repetitions progressing to 30

• Baseline measurements 3 times over 6 weeks before intervention, immediately after intervention, then follow-up at 6 weeks and 3 months

Haslam [19]

• Acupuncture

• Exercise therapy

• 32 subjects referred from specialist clinics (> 39 years)

• OA hip diagnosed with radiology, excluding RA, steroid injection, and hip surgery. Mean duration of symptoms was 6 and 9 years

• No information provided concerning baseline pain levels

• Acupuncture vs. exercise therapy

• Two groups of 16 subjects:

    Acupuncture
: 25 minutes, 1×

per week for 6 weeks

    Exercises and advice
: baseline visit and 3-week check-up to correct exercises and progressed gently

• 5 exercises (not described)

• Measurements before and after intervention, then follow-up at 2 months

    Self-reported pain and function

Modified WOMAC questionnaire

Hoeksma et al. [15]

• Combined exercise therapy

• Comparison intervention

manual therapy

• 109 subjects referred from specialist clinics (> 60 years)

• Unilateral OA hip diagnosed by using American College of Rheumatology criteria (with approximately 80% of subjects moderate to severe). Hip symptoms ranged from 1 month to ≤ 10 years

• Baseline mean pain level during walking was 29 and 34/100 within groups

• Exercise therapy vs. manual therapy

• Two groups of 109 subjects:

    Exercise therapy
: (53 subjects) 25 min 2× per week for 5 weeks, total of 9 individual sessions + home program

    Manual therapy
: (56 subjects) 25 min 2× per week for 5 weeks total of 9 individual sessions (hip-joint stretches, manual traction, manipulation traction and education)

• Strengthening with weights, endurance (treadmill or cycling), range of motion, stretches, balance, and education).

• Measurements before and after intervention and then follow-up at 3 and 6 months

• Hydrotherapy and education

• One control (education only) and one comparison intervention (electro-acupuncture and

education)

• 45 subjects referred from specialist clinics (> 42 years)

• OA hip diagnosed by general practitioner with x-rays and pain consistent with OA

• Baseline median pain level during loading was 37, 55, and 56/100 within groups

• Hydrotherapy vs. control

vs. acupuncture

• Three groups of 15 subjects:

    Hydrotherapy & education
: 30 min, 2× per week for 5 weeks (10 sessions)

    Electro-acupuncture & education
: 30 min, 2× per week for 5 weeks (10 sessions)

    Education only
: 2-hr group session, 2× over 5 weeks. Included exercises undertaken once per day

• 10 exercises (not described) to improve joint strength, stability, and range of motion

• Measurements before and after intervention, then follow-up at 1, 3, and 6 months
