Treatments
A six-pillar approach, without surgery
In the majority of cases, FHL is treated effectively without surgery. Conservative management combines physiotherapy, core strengthening, osteopathy, foot core work, and foot orthoses to release the tendon, restore its gliding, and reharmonize gait.
Treatments
Comprehensive, progressive care
Once the diagnosis of functional hallux limitus has been established, the physician first directs the patient toward conservative management. The foundation of treatment is mobilization of the subtalar joint by a healthcare professional familiar with this pathology. Before stretching exercises can be considered, free gliding of the flexor hallucis longus tendon must first be restored. Physiotherapy exercises are then performed at home.
Signature maneuver
The Hoover cord maneuver
Imagine a vacuum cleaner cord stuck under a table leg. Pulling on it along its axis is useless; you have to change the angle of traction to free it. The big toe tendon follows the same logic. The maneuver, developed at the Centre du pied, releases the blockage by traction along the axis of the calcaneus with progressive shearing movements. Once the tendon is freed, the stretch test becomes negative and stretching exercises finally become effective.
Osteopathy complements physiotherapy. FHL disrupts the mechanics of gait, with repercussions throughout the body, particularly the lumbo-abdomino-pelvic complex. Joint blockages such as the sacroiliac joints or the thoracolumbar junction are frequent and must be released alongside physiotherapy.
Orthopedic treatment is not limited to unblocking the tendon. Once the foot has been released, it must be reawakened by toning the short muscles to give it a solid base. The program is completed by correcting the forward-leaning posture imposed by FHL, through abdomino-lumbo-pelvic core strengthening exercises.
The six pillars of management
Each pillar plays a distinct but complementary role. None is sufficient on its own. It is their combination that ensures long-term treatment success.
Pillar 1 · Physiotherapy
Physiotherapy is the cornerstone of management. It systematically begins with a detailed assessment, then combines local treatment of the tendon with global postural rebalancing. The patient’s motivation to practice their exercises between sessions is decisive.
Step 1
Initial functional assessment
- Posture, gait, balance
- Joint function, muscle testing, pain
- Sports and occupational history
Step 2
Local treatment
- Hoover cord maneuver
- Selective tendon stretching
- Guided stretching exercises at home
Step 3
Comprehensive management
- Muscle and capsular rebalancing
- Hip flexibility work
- Treatment of associated muscle tightness
Step 4
Progress evaluation
- Six sessions on average
- Failure declared after 6 to 8 sessions
- Possible surgical referral
Practical advice
Encourage barefoot walking whenever possible, and strictly avoid wearing flip-flops, clogs, or Crocs, which worsen gait imbalance.
Pillar 2 · Abdomino-lumbo-pelvic core strengthening
The trunk is the central block around which the limbs and head articulate. Good stability of this block is essential for developing effective force in the segments attached to it. By imposing a forward projection of the trunk, FHL destabilizes this foundation. Core strengthening restores it.
Girdle 1
Abdominal girdle
Muscles connecting the rib cage to the pelvis, which stabilize the lumbar spine. Training mainly involves isometric or small-amplitude contractions.
Girdle 2
Pelvic girdle
Muscles connecting the pelvis to the abdomen and lower limbs. The skills sought are fatigue resistance and keeping the bony structures stable.
Progression
As the level increases, ground contact points are reduced and support on unstable surfaces is increased. Technical rigor is essential. Poor execution can generate tension and make the situation worse, hence the importance of professional supervision.
Pillar 3 · Foot core, core strengthening for the foot
The foot is made up of a passive framework (bones, joints, ligaments) supported by an active framework of short intrinsic muscles. Wearing shoes in our modern societies deconditions these muscles, which worsens FHL by promoting collapse of the arch. Foot core training strengthens this supporting musculature.
Target muscles of the protocol: abductor hallucis, flexor digitorum brevis, quadratus plantae, dorsal interossei.
The short foot
Stimulates the abductor hallucis, flexor digitorum brevis, and quadratus plantae. Creates a contraction of the arch without curling the toes.
Tips
Slow, controlled contraction
No toe curling
10 repetitions × 3 sets
Toes spread out
Targets the dorsal interossei, important for keeping the metatarsals in position during weight-bearing.
Tips
Spread the toes as far as possible
Hold the position for 5 seconds
10 repetitions × 3 sets
The snail drawing
Targets the adductor hallucis. Excellent for training overall foot dexterity. Requires an A4 sheet of paper and a pen.
Tips
Pen held by the toes
Slow spiral drawing
5 minutes per foot
Typical program
Six weeks of care, with one to two sessions per week in the clinic. Home exercises once or twice a day. The final strengthening stage involves supervised barefoot running or running in minimalist shoes.

Pillar 4 · Osteopathy
Osteopathy harmonizes the whole body when a reversible dysfunction is present. FHL causes disorders at multiple levels that often warrant osteopathic intervention alongside physiotherapy. The discipline is suitable for all ages, including children.
Locally — Mobilization of the subtalar joint (Hoover cord maneuver), treatment of the proximal tibiofibular joint, often involved through disturbed rotational synchronism, and massage of the popliteus muscle to facilitate manipulation.
Repercussions on the pelvis — Anterior pelvic tilt alters the force vector of the gluteus medius, recruiting the piriformis, which tightens. The resulting shortening limits the excursion of the sacroiliac joint, which can become fixed in malposition, creating a false short or false long leg.
Repercussions on the back — The forward tilt of the trunk overloads the trunk erectors, accentuates lordosis, and stiffens the lumbar segment. A trigger point at the thoracolumbar junction is frequent. The problem then shifts to the cervical level, a source of headaches and limited rotation.
Pediatric application — The stretch test can be performed from infancy. An in-toeing gait in young children should raise concern. Hindfoot manipulation combined with daily FHL stretches performed by the parents gives excellent results. At-risk population: young dancers and skaters training on demi-pointe.
Pillar 5 · Sports activities, the return to movement
Once the tendon has been released, you must relearn how to use your foot and your whole body in a harmonious way. FHL affects the entire biomechanics. This movement retraining can require several dozen hours for complex sports such as ball sports.
recommended
Nordic walking
An outdoor activity for all seasons, accessible at any age. Straightens the body, harmonizes the spinal curves, and stimulates balance.
progressive
Running
Moderate practice (less than 20 km per week). A running school is recommended for technique. Not recommended for untrained people over 40.
specific
Pivoting sports
Tennis, skiing, basketball. Specific preparation required, explosive-power work, ground anchoring on unstable surfaces; foot orthoses are useful.
« The foot needs to move freely and to be stimulated by the surfaces it rests on. All barefoot activities are beneficial. Yoga, martial arts, and gentle gymnastics are excellent allies in the relearning process. »

Pillar 6 · Next-generation foot orthoses
Conventional foot orthoses are designed in a static position and lock the foot into a rigid posture. This approach bypasses the action of the intrinsic muscles, which atrophy. The concept developed for FHL is radically different.
Conventional approach
Molded static support
Designed in a motionless standing position. Locks the foot into a set posture. Suitable for diabetes and severe deformities. Major drawback: progressive atrophy of the intrinsic muscles through disuse.
FHL approach
Guided dynamic support
No rigid molding. Calcaneal stirrups for postural feedback, a medial counter to resynchronize the roll-over of the foot, and cushioning under the first metatarsal. The foot remains free to stretch and to play its muscular role.
The orthosis acts as a guide, not a corset. It prevents the abrupt tip into pronation imposed by FHL at the end of the stance phase, without constraining the foot. The proprioceptive feedback stimulated by the stirrups activates the intrinsic muscles and provides a solid base for aligning the upper body.
When to move on to surgery?
Surgical treatment remains the most effective option when conservative treatments fail. A physiotherapist or osteopath familiar with the pathology considers treatment to have failed after six to eight well-conducted sessions, when the subtalar blockage recurs despite manipulations and stretching exercises.
Surgery may also be indicated from the outset, particularly when mobilization of the subtalar joint is difficult or impossible, or in the presence of a poorly tolerated, symptomatic hallux rigidus.
