AI Article Synopsis

  • The study investigates the effects of end-range and not end-range Maitland mobilization techniques on pain sensitivity and functional measures in patients with knee osteoarthritis.
  • Sixty-six patients were randomly assigned to receive either end-range mobilization, not end-range mobilization, or a sham therapy, with evaluations conducted before, immediately after, and a few days post-intervention.
  • Results showed that end-range mobilization significantly improved pain thresholds, reduced time on the Timed Up and Go Test, and provided benefits that persisted over a short-term follow-up compared to the sham technique and not end-range mobilization.

Article Abstract

Background: Hyperalgesia is attributed to peripheral and central sensitization in knee osteoarthritis (OA). Pressure pain threshold (PPT) is a relevant method for evaluating pain sensitivity in knee OA. The effect of end-range and not end-range Maitland mobilization for certain time-period on pain sensitivity has not been investigated in knee OA.

Aim: The aim of this study was to investigate the effect of end-range and not end-range Maitland mobilization compared to sham manual therapy technique on PPT and functional measures.

Design: Randomised, controlled clinical trial.

Setting: Outpatient setting.

Population: Sixty-six patients with mild-to-severe knee OA.

Methods: Twenty-one patients (N.=21) received end-range Maitland mobilization (EMGr), twenty patients (N.=20) received not end-range Maitland mobilization (nEMGr) and twenty-two patients (N.=22) received sham manual therapy technique (CG). All interventions were performed once. Evaluation was conducted pre-, postintervention and on the following consecutive second days within a 6-day period. Outcomes were local and distant PPT, Timed Up and Go Test (TUG) and strength of passive resistance of knee at onset of pain.

Results: Local and distant PPT increased, TUG time and strength of passive resistance decreased immediately, local and distant PPT remained decreased in 6-day and 4-day period, TUG time remained decreased in 6-day period in EMGr (all changes P≤0.017). Local PPT increased immediately compared to baseline in nEMGr. In between group comparison, increase of local, distant PPT and strength of passive resistance endures on 2 day, 4 day and postintervention, respectively, in EMGr compared to CG. EMGr compared to nEMGr presented significant difference on 6 day and 4 day in local and distant PPT, respectively (all changes P≤0.021). NEMGr presented no significant difference compared to CG on either follow-up.

Conclusions: Single end-range Maitland mobilization is effective immediately and in 4-day period on pain sensitization and immediately on physical function compared to not end-range Maitland mobilization and sham manual therapy technique in knee OA.

Clinical Rehabilitation Impact: Based on the present results, applying end-range Maitland mobilization is suggested on every second day to maintain alleviation of pain sensitization and increasing passive knee joint mobility effectively in knee OA.

Background: Pressure pain threshold (PPT) is a widely applied method for measuring the magnitude of increased peripheral and central pain sensitivity causing hyperalgesia in knee osteoarthritis (OA). Although manual therapy techniques effects positively PPT, the effect of end-range Maitland mobilization has not been evaluated in knee OA.

Aim: The aim of this study was to investigate the effect of end-range Maitland mobilization compared to sham manual therapy technique on PPT and function-related measures.

Background/aim: Different manual therapy techniques and conservative therapy have been used separately for alleviation of pain and improvement of physical function in patients with knee osteoarthritis (KOA). However, no study has reported the effect of combination of these treatment modalities in the management of KOA. Our aim was to test the feasibility of the study design and to compare the effect of end-range Maitland mobilization to conservative therapy in KOA.

Background: Manual therapy of the cervical spine has occasionally been associated with serious adverse events involving compromise of the craniocervical arteries. Ultrasound studies have shown certain neck positions can alter craniocervical arterial blood flow velocities; however, findings are conflicting. Knowledge about the effects of neck position on blood flow may assist clinicians in avoiding potentially hazardous practices.
