Descrição detalhada

A randomized controlled trial is conducted with a total of 54 non-professional ballet dancers recruited from ballet studios across the Klang Valley following inclusion and exclusion criteria. Baseline measurement of calf muscle performance was conducted before randomization using knee-to-wall (KtW) test, handheld dynamometer (HHD) and Y-balance (YBT). Participants were allocated to experimental (NM and self-stretching) or control (self stretching) .

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: Neural mobilisation group
neural mobilisation of tibial nerve and gastrocnemius stretching
Outro: Neural mobilisation
the neural mobilisation was done with placement of participant's leg in hip flexion, knee extension, ankle dorsiflexion and eversion to load the nerve. Then leg is placed back to neutral position, with ankle naturally plantarflexed to unload the nerve. NM of tibial nerve was done in a total of 10 seconds each repetition, with 5 seconds each for loading and unloading of nerve. Then 12 repetition was done in one set, which amount to a total of 120seconds or 2 minute per set. A total of 3 sets was done on each leg, with a 1-minute resting interval after each set. NM was administered to participants in experimental group before their ballet class for 3 times a week lasting for 4 weeks.

  • nerve tensioning
Outro: Gastrocnemius stretching
Participants was instructed to perform the classic wall stretch for gastrocnemius as self-stretching for a duration of 30 seconds each leg. It was done facing the wall and one leg had knee flexed in front while the other leg had knee extended behind. A 30 second hold was maintained at maximum stretched position by leaning forward while both soles of feet remain contact on the ground. Self-stretch was performed throughout the 4-week study duration before every ballet training or class.
Outros nomes:
  • calf self stretching
Comparador Ativo: Gastrocnemius stretching group
Participants was instructed to perform the classic wall stretch for gastrocnemius as self-stretching for a duration of 30 seconds each leg. It was done facing the wall and one leg had knee flexed in front while the other leg had knee extended behind. A 30 second hold was maintained at maximum tretched position by leaning forward while both soles of feet remain contact on the round. Self-stretch was performed throughout the 4-week study duration before every ballet training or class.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
knee to wall test
Prazo: From enrollment to the end of treatment at 4 weeks
The participants placed the testing foot onto the measuring tape with foot perpendicular to the wall while lunging or bending the knee to touch the wall. Then participants slide their foot further away from the wall as much as ossible while maintaining contact of knee to the wall as well as heel of foot on the floor. The calf muscle flexibility is evaluated with the measurement of distance from the great toe to the wall will be the maximum possible ankle dorsiflexion for the individual.
From enrollment to the end of treatment at 4 weeks

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Calf muscle strength
Prazo: From enrollment to the end of treatment at 4 weeks
Calf muscle strength was measured using handheld dynamometer (HHD).The device was placed at the plantar aspect of metatarsophalangeal joint height and the body of HHD should be maintained perpendicular to the plane of ankle plantarflexion movement. Isometric contraction of ankle plantarflexor was done in maximum possible force for 5 seconds. Participant performed one trial to familiarize with the test, followed by 3 repetitions alternated on each leg with 1-minute resting interval.
From enrollment to the end of treatment at 4 weeks
Dynamic balance using Modified Star Excursion Balance Test (mSEBT)
Prazo: From enrollment to the end of treatment at 4 weeks
Participants maintained their hands on the hip and reached tip of hallux to the maximal distance. The reaching foot were to avoid touching the ground and the heel of standing foot should remain on the ground. One trial on each direction was performed to familiarize with the test, followed by three trials with 1 minute resting interval. Normalize reach distance to lower limb length and normalized composite score were calculated to ultimately evaluate dynamic balance of an individual.
From enrollment to the end of treatment at 4 weeks
