About

Pes planus, commonly known as flat feet, is a condition characterized by a reduced or absent arch in the foot, which often leads to pain and functional limitations. This study aims to evaluate the effectiveness of two therapeutic interventions-tissue flossing and myofascial release-in improving balance, arch height, and range of motion (ROM) in patients with flexible flatfoot. The research will be conducted at the Margalla Rehabilitation Center over a duration of six months, involving a total of 44 participants divided into two equal groups. One group will receive tissue flossing as the intervention, while the other group will undergo myofascial release. Participants will be selected using non-probability convenience sampling. Eligible individuals will be adults aged 18-25 years with flexible pes planus and limited ankle dorsiflexion. The study seeks to provide valuable insights into the comparative effectiveness of these interventions for managing symptoms associated with flat feet. Data was be analyzed through SPSS version 25.

Full description

Pes planus, or flat feet, is characterized by a reduced or absent arch, causing the entire sole to contact the ground. It is categorized into flexible and rigid types, with flexible pes planus being more common. In this form, the arch is visible in non-weight-bearing positions but flattens during standing or walking, while rigid pes planus remains flat irrespective of weight-bearing. The condition often results in foot instability, excessive eversion, and midfoot abduction, leading to pain, fatigue, and reduced shock absorption during activities.

Flexible flatfoot is prevalent in children but can persist into adulthood, affecting 2% to 23% of adults in the U.S. and 13.6% in India. It disrupts gait mechanics, shifting weight medially, impairing balance, and increasing injury risk. Management ranges from conservative treatments like physical therapy to surgical interventions in severe cases.

Emerging therapies include tissue flossing and myofascial release (MFR). Tissue flossing uses compression bands to improve blood flow, reduce pain, and enhance range of motion (ROM). In contrast, MFR applies sustained pressure to relieve fascial tension, promoting flexibility and reducing discomfort. Both techniques show promise for addressing the biomechanical and functional impairments associated with pes planus.

Literature review: According to literature, Galis et al. (2022) performed a study that aimed to examine the effects of applying tissue flossing band at different pressure levels on ankle ROM, strength and power performance in university students. The results showed an increase in dorsiflexion ROM and power. Furthermore, the author concluded that this can aid injury prevention, performance enhancement, and functional ability.

In another study, Driller et al. (2016) conducted a study on the effects of tissue flossing on ankle ROM and jump performance in recreational athletes. The study concluded that applying floss bands to the ankle effectively increased both dorsiflexion and plantarflexion ROM and enhances single-leg jump performance in recreational athletes.

Similarly, Choi et al. (2022) conducted a study aimed at investigating the impact of myofascial release of the peroneus longus muscle on the activity of the abductor hallucis muscle and the medial longitudinal arch in individuals with flexible pes planus. The results showed an increase in abductor hallucis muscle activity and elevation of the medial longitudinal arch.

A study conducted by Chang et al. (2021) examined the effect of a single session of tissue flossing on the knee joint in female college students. The results showed a significant improvement with a medium-to-large effect in the Y-Balance test assessment immediately postintervention. He concluded that tissue flossing can indeed enhance dynamic balance.

44 participants in 2 patient groups

Tissue flossing

Experimental group

Description:

* Tissue flossing involves wrapping a latex band around the calf muscles with 50-75% elongation, followed by active ankle movements (dorsiflexion, plantarflexion, circles, heel raises). * Protocol: 4 sets of 8 repetitions, 10-second rest between sets * Performed twice weekly for 3 weeks. Conventional Treatment

Treatment:

Other: Conventional treatment

Other: Tissue flossing

Myofascial release

Active Comparator group

Description:

* Myofascial release is a manual therapy applying sustained pressure on the calf muscles to release fascial restrictions. * Protocol: 3 sets of 2-minute pressure applications with a 1-minute break between sets * Performed twice weekly for 3 weeks Conventional Treatment

Treatment:

Other: Conventional treatment

Other: Myofascial release
