Peak et al (2005) Randomised controlled trial<br />

Hypothesis: dislocation is more<br />

likely to occur in service users<br />

who are not placed on postoperative<br />

functional<br />

restrictions (PFR) following<br />

total <strong>hip</strong> <strong>replacement</strong><br />

Randomised pre- operatively<br />

Of 630 eligible consecutive<br />

service users, 265 (303 <strong>hip</strong>s)<br />

consented to be randomised<br />

into ‘restricted’ or<br />

‘unrestricted’ group<br />

Restricted group n=152<br />

Unrestricted group n=151<br />

Mean age 58.3 years<br />

Male: female ratio = 139:126<br />

United States <strong>of</strong> America.<br />

THR – both groups:<br />

limit range <strong>of</strong> flexion,<br />

external and internal<br />

rotation, and avoid<br />

adduction during first 6<br />

weeks<br />

Restricted group: to<br />

maintain abduction<br />

while in bed, used<br />

raising equipment,<br />

prevented from<br />

sleeping on side, from<br />

driving or being a car<br />

passenger<br />

Unrestricted group: not<br />

required to follow<br />

additional restrictions,<br />

could choose to use<br />

equipment for comfort.<br />

Self- administered survey/<br />

diary to check compliance<br />

Completed surveys<br />

returned at first postoperative<br />

visit – 6 weeks<br />

after surgery<br />

Final survey at second<br />

follow- up visit about 6<br />

months after surgery<br />

• Number <strong>of</strong> dislocations<br />

• Service user satisfaction<br />

related to maximised<br />

functional<br />

independence/<br />

resumption <strong>of</strong> roles<br />

• Length <strong>of</strong> hospital stay<br />

• Cost.<br />

At 6 month follow-up, unrestricted<br />

group reported a much greater<br />

degree <strong>of</strong> satisfaction re return to<br />

pre- operative daily activities.<br />
