About this study

Official title: EFFECTS OF SUBTALAR JOINT MOBILIZATION WITH AND WITHOUT FOOT CORE STRENGTHENING ON PAIN, DYNAMIC BALANCE, POSTURE AND DISABILITY IN PATIENTS WITH CHRONIC PLANTAR HEEL PAIN

Chronic plantar heel pain is one of the most common musculoskeletal disorders affecting the foot and ankle region. It is frequently associated with plantar fasciitis and is characterized by pain at the medial calcaneal tubercle, especially during the first steps in the morning or after prolonged periods of rest. Chronic plantar heel pain negatively affects gait mechanics, balance, foot posture, functional activities. The condition is prevalent among physically active individuals, overweight adults, and people with prolonged standing occupations. Despite the availability of several conservative treatment approaches, optimal management remains controversial. Subtalar joint mobilization is commonly used in physiotherapy practice to improve joint biomechanics, restore mobility reduce pain, and enhance functional movement patterns. Similarly, foot core strengthening exercises aim to activate intrinsic foot muscles, improve medial longitudinal arch stability, and enhance dynamic balance and postural control. Recent evidence suggests that both interventions may independently improve symptoms associated with plantar heel pain; however, limited literature is available regarding their combined effectiveness.

The purpose of this study is to compare the effects of subtalar joint mobilization with and without foot core strengthening on pain, dynamic balance, foot posture and disability in patients with chronic plantar heel pain.

This study will be a randomized clinical trial conducted on individuals diagnosed with chronic plantar heel pain. Participants will be randomly allocated into two groups. Group A will receive subtalar joint mobilization +Baseline treatment, while Group B will receive subtalar joint mobilization combined with foot core strengthening exercises+baselinetreatment. Outcome measures will include Numeric Pain Scale (NPRS) for pain, Foot Function Index (FFI) for functional disability, Y-Balance Test or Star Excursion Balance Test for dynamic balance, Foot Posture Index-6 (FPI-6) for foot posture assessment.

The intervention protocol will be conducted over a specified treatment duration with pre- and post-treatment assessments. Data will be analysed using SPSS software. The findings of this study may provide evidence regarding a more effective rehabilitation strategy for patients with chronic plantar heel pain and may help physiotherapists improve clinical decision-making and patient outcomes.

Read the detailed description

This study will investigate the effects of subtalar joint mobilization, with and without foot core strengthening, on pain, dynamic balance, foot posture, and disability in patients with chronic plantar heel pain. Participants will be divided into three groups. All groups will receive the baseline treatment, while Group A will additionally receive subtalar joint mobilization and Group B will receive subtalar joint mobilization combined with foot core strengthening exercises. The intervention will be delivered three times per week for four weeks, for a total of 12 supervised sessions. Outcomes will be assessed before and after the intervention using the Numeric Pain Rating Scale (NPRS), Y Balance Test, Foot Function Index (FFI), and Foot Posture Index-6 (FPI-6).

Arm Description: baseline treatment only Participants will receive baseline treatment consisting of pulsed ultrasound (50% duty cycle, 1 MHz, 1.5 W/cm² for 5 minutes), plantar fascia-specific stretching, gastrocnemius stretching, and soleus stretching. Stretching will be performed for three sets of three repetitions, with each stretch held for 30 seconds. Participants will also be instructed to perform the stretching exercises at home twice daily. Treatment will be provided three times per week for four weeks.

Experimental Group A-Basline treatment+Subtalar joint mobilization Participants will receive the same baseline treatment as the control group, along with subtalar joint mobilization. Mobilization will be performed with the participant in a side-lying position. The talus will be stabilized while the calcaneus is grasped to apply lateral and medial gliding techniques to facilitate calcaneal eversion and inversion, respectively. Each glide will be applied for 1.5 minutes, for a total mobilization time of 3 minutes per session. Treatment will be delivered three times per week for four weeks.

Experimental Group B-Basline treatment+Subtalar joint mobilization +Foot core strengthening Participants will receive the same baseline treatment and subtalar joint mobilization as Group A, in addition to a progressive foot core strengthening program. Exercises will include foot doming, toe spreading, towel curls, double-leg heel raises, single-leg heel raises, balance-board exercises, and foot relaxation. During sessions 1-6 (weeks 1-2), exercises will be performed at the initial prescribed repetitions and durations. During sessions 7-12 (weeks 3-4), repetitions and exercise duration will be progressed according to the study protocol. Treatment will be delivered three times per week for four weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. NPRS

    The Numeric pain rating scale NPRS is an 11-point scale ranging from 0 to 10 used to assess pain intensity, where 0 indicates no pain and 10 indicates the worst pain imaginable.

    Measured: BASELINE AND AFTER 4 WEEKS

  2. FOOT FUNCTION INDEX

    The Foot Function Index (FFI) is a standardized questionnaire used to assess the impact of foot pathology on pain, disability, and activity limitation. The questionnaire contains 23 items divided into three subscales:

    • Pain Subscale • Disability Subscale • Activity Limitation Subscale Scores range from 0 to 100, with higher scores indicating greater disability and functional impairment

    Measured: BASELINE AND AFTER 4 WEEKS

  3. FOOT POSTURE INDEX-6 (FPI-6)

    The Foot Posture Index-6 is a clinical assessment tool used to quantify static foot posture. It evaluates six criteria:

    • Talar head palpation • Supra and infra malleolar curvature • Calcaneal frontal plane position • Talonavicular prominence • Medial longitudinal arch height • Forefoot abduction/adduction. Each item is scored from -2 to +2. Total scores range from -12 to +12. Interpretation: • Negative scores indicate supinated foot posture. • Positive scores indicate pronated foot posture. • Scores around zero indicate neutral posture.

    Measured: BASELINE AND AFTER 4 WEEKS

  4. Y-BALANCE TEST (YBT)

    The Y-Balance Test is a reliable measure of dynamic balance and neuromuscular control. It is a simplified version of the Star Excursion Balance Test. Participants maintain a single-leg stance while reaching in three directions:

    • Anterior • Posteromedial • Posterolateral Reach distances are recorded and normalized to limb length. Greater reach distances indicate better dynamic balance performance.

    Measured: BASELINE AND AFTER 4 WEEKS
