NCT04332900

Brief Summary

This is a crossover study that will investigate the immediate effects of a proximal therapeutic approach (SERF strap) and a distal one (foot orthoses) on knee pain intensity, global change, symptoms, ease of performance and confidence after each task and lower limb kinematics (hip adduction and internal hip rotation peak, rearfoor eversion peak) during functional taks (level-ground walking and stepping manoeuvres) in people with patellofemoral ostheoartritis

Study Arms (3)

Control condition

NO INTERVENTION

In this condition there will not be any application of therapeutic approach.

Intervention proximal condition

EXPERIMENTAL

The proximal therapeutic approach will be the SERF strap (S.E.R.F. strap; DonJoy Orthopedics, Inc., vista, CA).

Device: Elastic hip strap

Intervention distal condition

EXPERIMENTAL

The distal therapeutic approach will be a pair of foot orthoses with semi-rigid arch support and medial elevation at the forefoot and at the rearfoot by 7° each (Propulsão Produtos Biomecânicos, Minas Gerais, Brazil).

Device: Insole

Interventions

The SERF Strap consist of a thin, elastic material that is secured to the proximal aspect of the leg, wraps in a spiral fashion around the thigh, and is anchored around the pelvis. The line of action of the SERF Strap pulls the hip into abdcution and external rotation.

Also known as: S.E.R.F. Strap; DonJoy Orthopedics, Inc, vista, CA
Intervention proximal condition
InsoleDEVICE

Foot orthoses with semi-rigid arch support and medial elevation at the forefoot and at the rearfoot by 7° each that is made from a block of ethyl vinyl acetate with a thermo-moldable polymer (shore hardness of 45 A) and is manufactured through an automated computer numeric control machine (CNC routers).

Eligibility Criteria

Age40 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Reporting pain of at least 3 on an 11-point scale (0 for no pain and 10 for the worst possible pain) during the activities described above and on most days during the last month;
  • Have evidence of osteophyte formation in the patellofemoral joint on radiographs in the profile and axial skyline views through the Kellgren-Lawrence (K-L) grade ≥ 2, with minimal impairment in the tibiofemoral joint (KL \<2);
  • Body mass index (BMI) \<35 Kg / m². Participants with unilateral or bilateral symptoms will be included in the study.

You may not qualify if:

  • Current use or in the last 12 months of foot orthoses;
  • Previous history of fracture or recurrent subluxation of the patella;
  • Arthroscopic surgery or knee infiltrations in the last 3 months;
  • Osteoarthritis known in other weight-bearing joints, including the spine;
  • History of surgery on the hip, knee, ankle and foot joints;
  • History of ankle sprain in the last 12 months;
  • Osteotomy in the lower limbs;
  • Current physical therapy in the lower limbs or in the last 6 weeks;
  • Use of a cane or other walking aid;
